IBM WebSphere Application Server, IBM's WebSphere Application server, is the Java Platform, Enterprise Edition (Java EE) and Web Services application platform, IBM W The foundation of Ebsphere software platform. WebSphere Application Server delivers a secure, scalable, resilient application infrastructure that helps build, run, integrate, and manage dynamic, on-demand business applications. These infrastructures are required to implement service-oriented architecture (services oriented Application,soa).

Different business scenarios require different levels of application server functionality, and WebSphere Application Server V6 offers several different packages. Each product package is tailored to different solutions and requirements. As your business grows, you can upgrade to a product package that supports higher-level requirements in the was product family based on migration guidance.

In accordance with user requirements and product capability-oriented enhancements, the was family includes the following packages: WebSphere application Server Community Edition V1 WebSphere Application server-express V6 WebSphere Application Server V6.1 WebSphere Application Server network deployment V6.1 WebSphere Application Server for ZOS V6.1 WebSphere Extended Deployment V6

Figure 1. Product packs for WebSphere application Server family WebSphere application Server Community Edition V1.1: WebSphere Application Server Community Edition abbreviation was CE, is a lightweight Java EE application Server, which is based on the Apache Software Foundation's Open source application server project Apache Ger On the basis of Onimo. Was CE is designed to help you accelerate development and deployment, leverage the latest technology from the open source community, and provide an easy access and flexible foundation for building Java applications. was CE for small and medium-sized enterprises, can be free to download and use, and access to IBM's world-class technical support.WebSphere application server-express V6: The Express edition of WebSphere application Server is suitable for fast and easy application development. It provides full 1.4 support for Java EE. The Express edition is designed for basic programming and run-time needs for desktop developers whose run-time environment is for standards-based Web programming and component-based programming and Web Service. The management model for this product is a single-server environment, no clusters, and no centralized management of multiple server instances. Unlike other packages in the family, the Express edition includes the Rational Web Developer application development tool. The Rational Web Developer is an enhanced version of the WebSphere Studio Site Developer in the WebSphere application Server V5.WebSphere application Server V6.1: This is the basic version of was, and the Express version is functionally close, but it offers a different version and license for the package. The basic version of WebSphere application Server is located in a medium business or a department in a large enterprise.
The WebSphere Application Server package provides a trial version of Application Server Toolkit and Rational application Developer products. Application Server Toolkit includes a set of development toolset that supports the development, assembly, and deployment of Java EE 1.4 applications, and supports the development of java-based 5.

These functions are suitable for large and medium-sized enterprises.WebSphere application Server for ZOS V6.1: The WebSphere Application Server for ZOS V6.1 contains all the features of the WebSphere Application Server network Deployment V6.1, and for the IBM System The z server is optimized for running, while leveraging IBM z/OS's service quality advantages.WebSphere Extended Deployment V6: WebSphere Extended Deployment (WebSphere XD) is a platform for Java EE Application Virtualization. It is not an application server, it runs on top of an application server, and is used to aggregate application servers into a single grid or virtualized environment. In addition, WebSphere XD extends to a large extent the quality of service provided by the application server to maximize its scalability, manageability, flexibility, and performance.

Small tip:

Was's Express version basically contains the full functionality of the was base version, so that small and medium enterprises can develop the full application of Java EE based on the WebSphere application Server Express Edition. The main difference between it and the basic version is the licensing limit, the Express version can only support 2 CPU hardware servers, while the WebSphere Application Server basic version has no CPU limitations. In addition, the WebSphere Application Server network deployment contains all the features of the WebSphere Application Server Express Edition and the basic edition, and also passes deployment The manager process provides multi-machine hosting and centralized management.
