    IBM stock: one of the vital desirable Yields in Tech | killexams.com true Questions and Pass4sure dumps

    Even earlier than the recent abide circulation in the markets, overseas company Machines (NYSE:IBM) turned into already losing steam. but the fall-off in the markets has resulted in most captious losses for the 12 months. word that revert on exotic company Machines stock is an lousy -24%.

    Yet, here's in reality nothing new. during the eventual five years, the performance has been lackluster. The typical annual revert on the IBM inventory fee is -5.7%.

    As of now, the market value of IBM inventory is beneath $a hundred billion. It’s as if Wall road has thrown in the towel.

    youngsters, for price investors and contrarians, may there subsist a casual birthright here? Has IBM inventory finally hit ranges where a buy makes feel? smartly, I feel so.

    one of the crucial leading reasons is the proposed acquisition of crimson Hat (NYSE:RHT) for $34 billion in money. It’s truly the greatest deal in the company’s 107-yr background. And it appears relish an exemplar fit for the strategic course of IBM — that's, the hybrid cloud market. This comprises mixing public and private clouds, which will also subsist seamlessly shared. The setup offers for a magnificient deal greater security and control. however there is additionally the means to acquire exhaust of the public cloud for facts and app overflows.

    keep in intellect that the hybrid cloud is whatever that larger corporations select. It’s very nearly getting the “better of both worlds” of cloud expertise.

    For IBM, this could also subsist an incredible market opportunity. subsist cognizant that enterprises are best about 10% to 20% into their cloud experience. however this may still subsist accelerated with the hybrid cloud approach.

    And with the crimson Hat acquisition, IBM will develop into the No. 1 participant out there. crimson Hat has amassed key technologies relish middleware, virtualization, storage and containers.  besides the fact that children, the largest potential could subsist the business’s focal point on open supply development. this is where coders world wide acquire contributions to the technology, which helps to acquire it more advantageous and better. groups also occupy the benefit of customization — and here's vital for tangled IT environments.

    Yet, it’s vital to abide in intellect that IBM has additionally build together its own set of effective belongings for the hybrid cloud, such as with AI (artificial Intelligence), blockchain and safety. The commerce already has about $19 billion of the hybrid cloud market.

    Then there's the IBM Cloud private, which launched a year ago. For probably the most part, it has gotten a lot traction. the brand unusual platform has attracted greater than four hundred international organizations (many of these had been aggressive wins).

    bottom line on IBM inventory

    through the years, IBM has fallen behind different tech operators relish Alphabet (NASDAQ:GOOGL, NASDAQ:GOOG), Amazon.com (NASDAQ:AMZN) and Microsoft (NASDAQ:MSFT) when it comes to the cloud area. however with the pink Hat acquisition, IBM may still subsist in a position to acquire up for misplaced floor. more importantly, the deal is massive ample to movement the needle on the precise-line.

    meanwhile, IBM inventory has one of the crucial maximum yields in the tech world, at 5.56%. And the enterprise does occupy the resources to preserve the payout. hold in intellect that IBM continues to generate large free money flows, which occupy near to $5.4 billion this 12 months. The company will additionally droop inventory buybacks and can dump other businesses (one fresh deal was a sell off legacy assets to India’s HCL).

    and finally, the valuation on IBM inventory is certainly at fascinating stages. trust that the ahead expense-to-profits distinctive is only about 8.

    Now it’s actual that discovering the backside on IBM inventory has been a losing online game. but, then again, in simple of the very low cost valuation, a juicy dividend yield and the potential ferment from the crimson Hat deal, the shares in fact finish appear relish they are at a magnificient entry aspect at the moment.

    SNW '04: Eyeing on-demand storage, IBM refreshes software | killexams.com true questions and Pass4sure dumps

    ORLANDO, Fla. -- piteous a step closer to its goal of storage on demand, IBM Corp. today announced updates to its TotalStorage Open Software product line with the objective of helping users automate and virtualize their storage.

    Coming fresh on the heels of the company's release of the DS6000 and DS8000 storage arrays two weeks ago, the upgrades embrace enhancements to SAN File System, SAN Volume Controller (SVC), the TotalStorage Productivity headquarters and Tivoli Storage Manager (TSM). Taken together, the software upgrades demonstrate IBM's march to an on-demand environment, where storage resources are made available to the user as needed.

    Arun Taneja, founder and senior consultant of Taneja Group, Hopkinton, Mass., said the software upgrades should subsist seen in the context of IBM's DS6000 and DS8000 arrays. "Individually, the upgrades are not barn burners … but seen as a comprehensive amble to on-demand computing, they are important. I consider IBM is piteous faster than any company to this dream of virtualizing the whole data center."

    Taneja stressed that with SVC, IBM is doing virtualization the birthright way. "The SVC is a sheer virtualization product, because it doesn't supervision what kind of storage it's working with. It doesn't occupy to subsist the master of the network, as opposed to how HDS does virtualization in the array where you must occupy an HDS box."

    Each of the upgrades has improved scalability, ease of exhaust and the faculty to manage diverse storage devices, analysts said. Nancy Hurley, senior analyst, Enterprise Strategy Group, Milford, Mass., famed that although the announcement is broad, it does embrace simplified features that will benefit users. Hurley said the improved usability of TSM is the most captious piece. "I consider a lot of the features of TSM were 'hidden' before. They were either difficult to net to or had to subsist done through scripting," Hurley said.

    Here's a summary of the TotalStorage Open Software family of products:

    IBM TotalStorage SAN File System v2.2: Can enable policy-based movement and deletion of files among various tiers of storage, providing the faculty to match the value of data to the commandeer class of storage. Security permissions occupy been strengthened for heterogeneous file sharing among Windows, Linux and Unix environments. SAN File System also expands host support, including the faculty to extend SAN File System capabilities to the IP network. IBM TotalStorage SAN Volume Controller v1.2.1: SVC doubles the cluster size to eight nodes to deliver twice the performance and quadruples the number of supported virtual disks (4096 virtual disks per cluster) available to host applications. SVC can also manage more diverse storage environments by supporting attachment to Hewlett-Packard Enterprise Virtual Arrays and the unusual IBM TotalStorage DS8000 and DS6000, in addition to arrays from EMC and Hitachi Data Systems. SAN Volume Controller also provides replication capabilities for global mirroring through the CNT UltraNet Replication Appliance. IBM TotalStorage Productivity headquarters 2.1: A storage infrastructure management suite that provides features that hearten better installation, tighten integration with other TotalStorage Open Software products and enhance reporting flexibility. Direct integration with IBM Tivoli Storage Manager can allow users to easily set policies to automatically trigger Tivoli Storage Manager to back up or archive identified files. IBM TotalStorage Productivity headquarters 2.1 also offers a common agent across the suite, unusual reporting capabilities, and additional platform and device support. IBM Tivoli Storage Manager 5.3: This upgrade offers a unusual graphical user interface, installation and configuration tools.

    IBM spokespeople said SVC will subsist build to suited exhaust with CNT's unusual UltraNet Replication Appliance (URA). The Minneapolis, Minn.-based company today announced the availability of URA, which offers SAN-based local and remote heterogeneous data replication services over unlimited distances. IBM has certified the URA to extend their TotalStorage SVC to remote sites, providing additional cataclysm recovery. The URA's replication portfolio includes local and remote mirroring, snapshot replication and the faculty to roll back to previous snapshots.

    The CNT appliance is immediately available. The updated IBM TotalStorage Open Software products are expected to subsist available during the fourth quarter of 2004.


    CoreOS Tectonic Wants To Shake Up the Kubernetes World | killexams.com true questions and Pass4sure dumps

    Dan's Take

    CoreOS Tectonic Wants To Shake Up the Kubernetes World

    It's another case of the growth of DevOps.

  • By Dan Kusnetzky
  • 04/04/2017
  • CoreOS, which has taken on the mission "to better the security and reliability of the Internet," just announced that it's extended the capabilities of its Kubernetes solution, CoreOS Tectonic, to embrace more computing environments.

    This release is designed to support bare metal, Amazon Web Services and preview support for both Microsoft Azure and OpenStack. The company has also extended its container image registry, Quay, so that it can manage and store complete Kubernetes applications. The goal of both announcements is to hearten enterprises automate container-based application environments.

    CoreOS points out the following features of the extended Tectonic Installer:

  • Environment flexibility: An improved, scriptable installer makes it simple to deploy highly available, secure Kubernetes clusters by default. Repeatable across environments, users can try out customizations for their environments. Includes increased customization of networking and VPC options (including deploying into an existing VPC and subnet) and custom tagging for AWS resources.
  • HA deployment options: Users can now deploy a cluster with multi-worker, multi-controller and multi-node etcd (Kubernetes' distributed data store) on AWS and bare metal.
  • Simplified deployment: With the preview installer released in open source, users now occupy options to deploy Kubernetes on a host of cloud providers.
  • Automated: With the need for dev clusters, test clusters, QA clusters, and more, the installer allows users to redeem time and automate the install of their clusters.
  • The company also says that the unusual release of Tectonic includes Kubernetes version 1.5.5., which provides the following capabilities:

  • More self-driving capabilities: Addition of Dex, Flannel and the Tectonic Console in this release as components controlled by CoreOS's experimental Operators.
  • Tectonic Console: Now v1.0.0, with improvements to the navigation, menus and labels. The console displays node selectors and provides an editing modal, and has improvements in the Kubernetes and Tectonic channel statuses and oversight messages.
  • Dan's Take: Kubernetes Becoming a Mainstream ToolIf they consider CoreOS' announcement in the context of recent announcements coming from other suppliers, such as Red Hat, SUSE, IBM, HPE and others, the following things occupy become clear:
  • Containers is a technology now on the radar screen of enterprise developers. This trend can subsist attributed to the fact that virtual machine (VM) software doesn't always offer an acceptable merge of capabilities and machine overhead suitable for every bit of workloads. VMs are an approach that works well in a multi-OS computing environment. If the workload is going to subsist hosted on a single operating environment, the exhaust of VM technology as the foundation for encapsulating applications and application components may subsist too costly in terms of processing power, system memory, storage and networking requiremetns.
  • Multiple machine configurations based on system clustering, which has long been the foundation of commercial computing workloads, is now becoming a standard practice when containers are the application encapsulation and delivery tool.
  • This announcement obliquely supports the trend toward the exhaust of rapid progress and deployment approaches typically used under the banner of "DevOps". Developing services or microservices quickly and hosting them in containers that can execute in a clustered -- e.g., Kubernetes -- environment is on the surge as well.
  • Enterprises occupy an increasing number of options when it comes to the exhaust of containers and Kubernetes. Is CoreOS the best choice? That isn't really clear. What is lucid is that containers as a technology and the trend toward rapid progress and deployment environments got a boost by the company's product launch.

    Comparing the Technologies | killexams.com true questions and Pass4sure dumps

    Language and Runtime Support

    Java. Developed in 1995 by Sun. every bit of code is compiled into bytecode and interpreted by a virtual machine (JVM). May also subsist selectively JIT compiled, depending on the JVM, or fully natively compiled with ancillary products (such as JOVE). Can race on any platform that supports a JVM. IBM supports v1.3 of the J2SE SDK.

    VBScript and JScript for Web pages and any COM-based language for server components (typically VB or VC++). Scripts are interpreted, while components are natively compiled. VB code also requires a runtime DLL (MSVBMxx.DLL). VBScript and JScript came into exhaust in 1997, while COM grew out of OLE in 1993.

    Any language that supports the Common Language Runtime (20-plus in development). Initially compiled to an intermediate language (MSIL) and then JIT compiled to aboriginal code by the CLR at runtime or natively compiled (PreJit) at install time. Code written for the CLR is referred to as managed code. Support for the CLR will subsist shipped with future OSes starting with Windows XP Server released by the conclude of 2001.

    Class Libraries

    Standard Java classes create in the J2SE, plus the APIs (JDBC, JSP, EJB, JMS, JAXP, JCA, JFC, JNDI, and so on, as defined in the J2EE specification). In addition, vendors embrace their own extensions to J2EE for integration and differentiation in the marketplace.

    Win32, COM, MFC, ATL, and ASP. Five primary programming models that accommodate APIs that developers exhaust in building solutions.

    Services Framework. A hierarchical set of managed classes arranged in namespaces. Provides a consistent programming model and unifies the APIs needed to build solutions.

    Deployment

    Java Package. Collection of Java classes assembled as a unit and arranged hierarchically. Weak versioning. Server-based deployment uses XML-based deployment descriptors, which are read and handled differently by each vendor's implementation. WebSphere includes an application assembly tool to maneuver this process.

    DLL, EXE. DLLs accommodate a collection of functions with weak versioning. EXEs portray an executable program with weak versioning. COM components are housed in DLLs, rely on the registry, and support immutable interfaces but no runtime version checking. Server-based installation accomplished through third-party utilities such as InstallShield.

    Assembly. Unit of deployment, security, and versioning. Includes built-in PKI support and metadata to tightly control binding of assemblies at runtime. Support exists in the class loader of the CLR for consistency and version checking. Server-based deployment can subsist done in a no-impact mode by simply copying the relative paths that accommodate the application. Applications also can explicitly share components. Support for the Windows Installer included in VS.NET.

    Thin Client

    Java Server Pages (JSP). WAS supports JavaScript or Java in JSPs that are compiled into HttpServlets on the glide and are cached by the server. No aboriginal support exists for different devices, and there are no client-state services other than cookies. WAS ships with an HTTP engine (1.3.19) but can exhaust Apache, Domino, Netscape, iPlanet, or IIS 4.0/5.0. WAS 4.0 is v1.1–compliant. The syntax of JSPs is a knockoff of ASP and was developed in 1998.

    Active Server Pages (ASP 2.0). Technology introduced by MSFT in 1997 in which pages containing server-side code are interpreted by an ISAPI server extension and can exhaust simple HTTP caching through headers. No aboriginal support exists for different devices, and there are no client-state services other than cookies. ASP runs primarily on IIS 4.0/5.0 but has been ported to other platforms (see Chili!Soft, purchased by Sun). Performance of JSP and ASP is similar on similar hardware platforms.

    ASP.NET. ASP.NET pages are compiled into MSIL either statically or on the glide when a request is made. Server control architecture allows abstraction for different devices and state storage across HTTP POST events. Server controls allow developers to create "adaptive controls" to render HTML, WML, and so on as commandeer for the client platform. Runs on IIS 4.0/5.0. Beta performance tests attest a 200–300% improvement over JSP and ASP.

    Web Server Processing

    HttpServlets provide a request/response model available to Java classes in addition to session-state services keyed with a client cookie. JSPs often muster servlets as the controller that acts as the broker between presentation and commerce service layers to provide separation between the HTML and Java code. Because of the complexity of writing servlets many "two-tier Web apps" simply occupy the servlets acquire direct calls to the underlying database via JDBC. This leads to spaghetti code that is difficult to debug and maintain. The servlet engine is included in WAS and includes a JDBC connection manager that handles database connection pooling. WAS 4.0 is v2.2–compliant.

    The ASP runtime implemented in the ISAPI server extension provides a request/response model in addition to session- (keyed with a client cookie) and application-state services. ASP pages often muster commerce services directly implemented as COM components, although many "two-tier Web apps" simply occupy the ASP pages acquire direct calls to the database via ADO. This leads to spaghetti code that is difficult to debug and maintain.

    The HTTP Runtime in ASP.NET provides an extensible mechanism by which developers can hook into the processing of resources on the Web server through HTTP Modules. Provides very tight integration with the Web server. also supports a request/response model and application- and session-state services. Session-state services can subsist deployed on a separate server to multiply scalability. Provides a sophisticated caching mechanism for pages and programming code. Provides complete separation of HTML code and programming logic through code behind.

    Object Services

    Enterprise Java Beans (EJB). piece of the original J2EE specification in 1998. Java classes that are deployed in component-oriented middleware (a container) that provides interception and adds services such as distributed transactions (using the Java Transaction Service [JTS] based on the OMG and using IIOP), security, and database connectivity. The container can race on the very server or remotely. EJBs near in two flavors: entity beans and session beans. Entity beans map to the state of an protest as represented by a row in a database. Entity beans provide the mapping to the database and caching of the entity. Entity beans near in two styles: Container Managed Persistence (CMP) and Bean Managed Persistence (BMP). CMP beans allow the container to manage loading and saving the database information, whereas BMP beans provide methods for the developer to insert JDBC code directly. Session beans near in two flavors: stateful and stateless. Stateful beans maintain a conversation with a single client, whereas stateless beans can subsist reused by multiple clients, with the container handling the allocation. WAS 4.0 is EJB 1.1–compliant.

    Microsoft Transaction Server (MTS). Provides component-oriented middleware for COM components introduced in 1996. Provides interception and adds distributed transactions through the Microsoft Distributed Transaction Coordinator service (MSDTC), security, and protest activation support. Objects can subsist both stateful and stateless, depending on administrative settings. Programmers hold edge of MTS services through the exhaust of an API. Only components built in VC++ are free-threaded and thus achieve better. No support for automatically mapping database rows to protest instances exists.

    Component Services (COM+ 1.0). Released with Windows 2000 in 2000 and provides component-oriented middleware for COM components. Provides interception and adds distributed transactions, security, protest construction, protest pooling, queued components (for asynchronous integration with MSMQ), loosely coupled events for publishing and subscribing to components, and activation support. Objects can subsist both stateful and stateless, depending on administrative settings. Although built for COM, .NET programmers create serviced components in .NET by deriving their class from a system class and decorate it with attributes to portray the services that it uses. The system class then communicates with COM+ via Win32 and COM APIs. No support for automatically mapping database rows to protest instances exists. (The IMDB product that was removed from prerelease versions of COM+ would occupy served a similar purpose as entity beans, although the ADO.NET DataSet protest serves a similar purpose.)

    Database Support

    JDBC. Data Access API that allows SQL access to a tabular data source via drivers (there are currently 159 listed on Sun's site under 4 different types, ranging from JDBC to ODBC bridges to fully native-protocol Java implementations). Various drivers support connection pooling, distributed transactions, and rowsets, and some are J2EE-certified. The API is similar to the Win32 implementation of ODBC. JDBC 2.0 is the spec under J2EE 1.2, but 3.0 has been defined. Note that when using entity beans with CMP, the container provides the mapping to the database tables through a vendor-specific mechanism. WAS 4.0 supports JDBC core v2.1 and Extensions 2.0. WAS includes providers for DB2, MSSQL, Oracle, Informix, and Sybase.

    ADO/OLE DB. OLE DB is both a specification for COM interfaces that database vendors implement (OLE Providers) and a set of services (such as cursor processing and connection pooling) implemented in Windows to provide data access to a variety of data sources. ADO is a simplified automation layer that sits on top of OLE DB to provide data access to scripting languages and COM-based languages such as VB. Although typically used for tabular data access, both ADO and OLE DB can subsist used to access nonstructured data such as email and XML. OLE DB also can subsist used to access data through the plethora of available ODBC drivers.

    ADO.NET. A set of managed classes that provides access to data sources through what are called managed providers. These embrace TDS (SQL Server), OLE DB providers, and ODBC drivers. Each managed provider implements connections and connection pooling, commands/parameters, forward-only cursor processing, transaction processing, and oversight handling. ADO.NET also includes a middle-tier data cache protest called a DataSet that provides an XML-based cache of data that can subsist used to bind to controls and synchronize changes to a data source through an adapter protest implemented by the managed provider. Designed to support a loosely connected model with built-in XML representation of the data and XSD representation of the schema. Developers can work with relational data as XML data, and vice versa through the XMLDataDocument class.

    Messaging

    Java Messaging Services (JMS). JMS is a set of client interfaces to message-oriented middleware (MOM) products that supports both message queues and publish-and-subscribe metaphors. MOM vendors implement JMS providers. JMS includes a specification for a unusual type of EJB, message beans. WAS includes the (WebSphere MQ) MQSeries JMS provider. WAS 4.0 is compliant with the 1.0.2 specification and includes support for JMS-XA distributed transactions across MQSeries-enabled systems and databases. need to obtain WebSphere MQ separately.

    Microsoft Message Queue Server (MSMQ). A MOM server product running on NT 4 and W2K that supports message queues but does not embrace a publish-and-subscribe feature built into the product. The product includes a COM-based API for sending and receiving messages and administering queues. Supports distributed transactions through MSDTC. MSMQ is built into Windows NT 4.0 Server.

    System.Messaging. A set of managed classes that provide the administrative and client APIs for working with MSMQ servers. MSMQ is built into Windows 2000 Server. It should subsist famed that developers can access MSMQ through queued components (QC) supported by COM+ 1.0. QC acts as an abstraction layer to allow clients to asynchronously acquire way calls on components that are backed by MSMQ.

    Fat Client

    Java Foundation Classes (JFC). JFC includes the Abstract Windowing Toolkit (AWT) and Swing as Java APIs for building GUII applications. Swing is a more abstract API and includes a "look and feel" for developing the very GUI on multiple platforms or adhering to a platform standard. Advanced graphics can subsist created with the Java2D and 3D APIs. GUI apps race as standalone applications or applets running in a browser.

    Win32/ActiveX. Applications written in VB, VC++, or other Windows progress tools. Ultimately these tools acquire calls to the Win32 API for the underlying window management. ActiveX is a COM-based technology for building reusable binary visual components (.ocx) across progress environments. Applications race as standalone applications or as ActiveX controls hosted in MSIE. Advanced graphics are available through the DirectX set of COM-based APIs.

    Windows Forms. Set of managed classes that allow for the creation of forms-based applications. Takes edge of unusual Windows 2000 features such as nonrectangular forms. Includes a managed control architecture to build reusable visual controls. Third parties will provide wrappers for DirectX functionality. Windows Forms–based applications can race as standalone applications or can subsist hosted in MSIE on clients with the CLR installed.

    Integration

    J2EE Connector (JCA). JCA is a specification based on the IBM Common Connector Framework (CCF). WAS contains WAS adapters used to connect to packaged applications such as JDEdwards, SAP, Peoplesoft, and so on. These are JCA-compliant and are shipped with VisualAge for Java. You can also build unusual adapters using the MQSeries adapter offerings. WAS AE multiserver version only.

    SNA Server 4.0. Server product that includes OLE DB and ODBC support for AS/400 and DB2. also includes COM Transaction Integrator (COMTI) for working with CICS and IMS transactions as if they were COM objects. Includes MSMQ-MQSeries bridge and host printing services, among others. Basically, this is COM-based integration, and there are also connectors to packaged products such as the SAP DCOM Connector.

    Host Integration Server 2000. Update of SNA Server. also includes integration with Commerce Server, BizTalk, lively Directory, and Windows Management Instrumentation (WMI). BizTalk also supports application-integration components (AIC) that can subsist built to integrate with packaged applications; for example, there is a SAP R/3 AIC available.

    XML Support

    Java API for XML Parsing (JAXP). An API and abstraction layer to deal with various XML parsers. Not included in the J2EE 1.2, but 1.0 is in 1.3. v1.1 supports XSLT and DOM even 2 and SAX v2.0. IBM has a 100% Java validating XML parser with JAXP support available on its Web site. WAS includes support for DOM 1.0, SAX 1.0, and XSLT 1.0.

    MSXML. Microsoft's COM-based XML parser, included as a standalone addition to the OS and in products such as MSIE. Version 3.0 sp1 is the current version, with v4.0 as a technology preview on the MSDN Web site. V3.0 supports XSLT, XPath, and SAX2. Implements much of the DOM functionality specified by the WS3C, in addition to SAX support for event-based processing of large XML documents.

    System.Xml. A set of managed classes that implement the DOM, XSLT, and XPath specifications by the W3C. Supports both a tree-based model (DOM) and an innovative stream-based approach for parsing XML documents. also contains a class that maps XML documents to the ADO.NET DataSet class to provide XML-based access to relational data.

    Web Services

    WAS ships with the Apache SOAP 2.2 tool support. The toolkit is SOAP 1.1–compliant. Can expose Java classes, EJBs, BSF scripts, or DB2-stored procs as a Web Service. Includes a command-line utility to publish EJBs as SOAP services. progress tools accommodate wizards to create WSDL from an existing Java application or read WSDL to create a server stub or client proxy. UUDI4J support is also included for client-side interaction with UDDI registries.

    SOAP Toolkit 2.0. Downloadable. Current release is sp2. Provides a COM wrapper for implementing Web Services. Wizard exposes COM objects as a Web Service using ASP or IIS ISAPI extensions. Support for WSDL 1.1. A separate UDDI SDK is available for download, and provides a COM API for building and querying a UDDI registry. The toolkit integrates into VS 6.0 so that creating Web Services from COM components is straightforward.

    .NET Framework. SOAP 1.1 is implemented in a variety of the base class libraries and, therefore, is very tightly integrated from both consumer and implementer perspectives. Allows individual methods in managed classes to subsist exposed as Web Services through an assign of the framework. Automatic creation of WSDL from XSD schemas and managed classes. Automatic creation of managed client proxies from WSDL through the command line and UI in VS.NET with replete Intellisense. A separate UDDI SDK is available for download that provides managed classes for building and querying a UDDI registry.

    Remoting

    Remote way Invocation (RMI)-Internet InterORB Protocol (IIOP). Provides the programming model (RMI) and the protocol layer for (CORBA IIOP) Java-to-Java communication. Servlets and applets communicate with EJBs via RMI. Assumes a tightly bound model that creates firewall issues and is not well suited to the Internet.

    DCOM. Extension of COM for component communication across the network using any of the Windows NT network protocols. Includes remote activation and security features. Remoting of protest instances must subsist specifically programmed into the COM objects themselves. Assumes a tightly bound model that creates firewall issues and is not well suited to the Internet.

    .NET Remoting. Implemented in a set of managed classes. Allows managed code to communicate across app domain boundaries. Can communicate via HTTP or TCP channels. Supports remoting of protest instances via binary or SOAP protocols. Supports singletons and client activation. The exhaust of HTTP and SOAP promotes a loosely coupled architecture that does not incur firewall problems.

    Naming Services

    Java Naming and Directory Interface (JNDI). Programming interface that provides access to directory services such as DNS, LDAP, Novell (NDS), and CORBA COS through vendor-specific providers.

    WAS 4.0 is JNDI 1.2–compliant for EJB lookup. The IBM SecureWay Directory 3.2.1 product is included in WAS for access to lively Directory, Lotus Domino, and NDS.

    Active Directory Services Interface (ADSI). COM programming interface that supports access to NT, LDAP, and Novell (NDS) directory services through vendor-specific providers.

    Active Directory and System.DirectoryServices namespace. Windows 2000 Server includes the distributed directory used in a Windows 2000 domain while the managed classes, in DirectoryServices provide a wrapper around the ADSI interfaces to programmatically access a directory.

    Development Tools

    WebSphere Studio, Visual Age for Java. Both ship with WAS. Studio is used to build the visual representation of Web pages and JSPs, while Visual Age is used for Java coding of servlets, beans, and EJBs.

    Visual Studio 6.0, released in 1998 (three IDEs). Separate IDEs exist for VC++/Visual Interdev for ASP development, and VB for configuration and component development. Graphical Web development.

    Visual Studio.NET. Single IDE that supports unified debugging, project management, Intellisense, Server Explorer, graphical editor for the Web and forms, class view, dynamic help, add-ins, and scripting. Can subsist used to build console applications, Windows Forms, Web Forms, Web Services, Windows Services, and components. Third-party compiler vendors can plug into VS.NET.

    B2B Integration

    ebXML. An industry specification (not a shipping product) for performing business-to-business transactions using XML and the Web. Includes some support for SOAP. Not implemented in WAS. Would need to roll your own infrastructure perhaps using Web Services.

    No support on NT 4. Would need to roll your own infrastructure using the SOAP Toolkit and Windows services.

    BizTalk Server 2000, released in 2000. A separate server product that provides a messaging/scheduling engine and commerce process orchestration facilities. Messaging includes support for EDI, SOAP, and Rosettanet grammars, in addition to others.

    Key Strengths

    For organizations that must occupy platform neutrality, J2EE is the only alternative. The Java language is becoming more widely accepted. Vendors such as IBM offer a single-vendor solution when dealing with legacy applications. Separation of application logic and presentation exists, although, in practice, this is underutilized. EJB model includes automatic database-mapping facilities through CMP.

    Large base of VB/ASP developers, resulting in reduced costs. Runs on commodity servers that can subsist scaled out. Software costs are low. Multiple language support through COM. Tight integration with the dominant client platform (Windows).

    Multiple languages supported with a common set of class libraries. Unified programming model with the Services Framework. tall productivity progress environment. Web application performance. Runs on commodity servers that can subsist scaled out. Separation of application logic and presentation exists. Greater integration with XML and Web Services protocols. Tight integration with the dominant client platform (Windows).

    Key Weakness

    Single-language solution. Smaller base of developers. EJBs are tangled and not widely used. Thus, JSPs are overused, resulting in spaghetti code. Varying levels of J2EE conformance across vendors. The need to exhaust vendor-specific features leads to vendor lock-in. Performance varies due to vendor-specific implementations. Software cost is generally higher, developer costs are higher, and deployment time is increased.

    Highly fragmented programming model. COM infrastructure is unwieldy, leading to DLL hell and versioning problems. ASP pages that finish not utilize COM for commerce and data-access services lead to spaghetti code. Single-vendor solution.

    Not a shipping product. OO nature of CLR makes progress initially more complicated for VB/ASP developers. Single-vendor solution. Does not support an automatic mapping of database rows to objects as with CMP, although there is widespread disagreement within the industry as to whether entity beans are desirable because they finish not promote transactional consistency and are questionable in terms of performance.
