1. Concepts for Websphere Learning Notes
These days, you need to use Websphere for your work, so learn about this middleware after work. Today I’ll look at some concepts and the architecture of Websphere itself.
l Websphere
Concept from Baidu Baike:
Is IBM WebSpheresoftwareplatform. It includes writing, running, and monitoring an industrial-strength, on-demand Web around the clockThe applicationAnd acrossplatform, the entire middleware infrastructure, such as servers, services, and tools, required for cross-product solutions. WebSphere provides reliability, flexibility, and robustnesssoftware.
WebSphere ApplicationServer is the foundation of this facility, and all other products run on top of it. WebSphere Process Server is based on WebSphere Application Server and WebSphere Enterprise Service Bus and is service-orientedarchitectureModularity (SOA)The applicationProvides the foundation and enables the application of business rules to drive applications that support business processes. High-performance environments also use WebSphere Extended Deployment as part of their infrastructure. Other WebSphere products provide a wide range of other services.
WebSphere is modularplatform, based on industry-supported open standards. You can continue to scale the environment by plugging existing assets into WebSphere through trusted and persistent interfaces. WebSphere is available in manyplatformRun on Intel, Linux, and Z /OS.
WebSphere is the mainstay of the on demand e-business erasoftwareplatform, which can be used by enterprises to develop, deploy and integrate a new generation ofThe electronic commerceApplications, such asB2BAnd supports business applications ranging from simple web content publishing to enterprise transaction processing. WebSphere can createThe electronic commerceSite that extends applications to federated mobile devices, consolidates existing applications and provides automated business processes.
The concept is quite abstract, but very comprehensive. If we don’t understand it well now, it’s ok to understand it slowly later. After all, such a large software platform is the same in concept.
L SOA (Service-oriented Architecture)
Let’s take a look at the concept from Baidu Baike:
Service-oriented Architecture (SOA) is a component model that willThe applicationThe different units of functionality (called services) are connected through well-defined interfaces and contracts between these services. Interfaces are defined in a neutral manner and should be independent of the hardware platform implementing the service,The operating systemAnd programming languages. This allows services built on a variety of systems to interact in a unified and common way.
L architecture
Websphere Application Server provides an environment for deploying middleware solutions. The core component is the application server running environment, which provides the framework for business application running. An application server provides a set of services that business applications need to run and provides a platform for developing and deploying these applications.
Just as the business needs to upgrade, new technical standards emerge. Since 1998, Websphere Application Server has evolved and adapted to the latest technologies and standards. It provides an innovative, cutting-edge environment for designing fully integrated, standards-based solutions.
