采用Web 2.0技术:快速、简单地开发与部署应用

Web 2.0 and RESTful SOA

Simple to use Simple to access

AJAX•Highly Interactive•Browser invoked services

JSON / XML / ATOM •Information exchange•JavaScript Friendly

REST•Easily invoked•HTTP-Centric Patterns

Web 2.0 Support

Ajax Messaging For connecting Ajax clients to real-time updated data like stock quotes or instant messaging.

Ajax Application

IBM $125.25 +$2.50… MSFT $43.75 -$1.50 …

Ajax Development ToolkitBased on Dojo (dojotoolkit.org) with IBM extensions. Reduces time to market and helps lower Ajax adoption costs.

EJBs POJOsSOA

Ajax Proxy

WebSphereApplication Server

ServiceBus (JMS)

Web 2.0 to SOA ConnectivityFor enabling connectivity from Ajax clients to SOA services and other JEE assets. Extends enterprise data to customers and partners through web feeds.

Web Feeds

• WebSPhere sMash Strategy – Embed in products including

CICS, WMB and Rainmaker– Web-based Developer Tools

(Forms applications)– Partner enabling

REST enabled WebSphere Portfolio

Model application data• Constrained set of APIs encourage a RESTful application

architecture• Data model that maps well into Atom feeds and JSON

formats• Robust framework for persistence, validation, and

serializationAccess resource data with Dojo

WebSphere sMash application

Light-weight Flow in WebSphere sMash

• Assemble Flow is target to compose application with the flow pattern by “wiring” activities.

Pain Points:•Many Apps in a few JVMs in Shared Common AP Servers

•Cannot visualize/understand each Apps behavior

•Not all Apps are well-behaved

Solution:1. Add WVE between Web Server and WAS2. Health Control3. Operational ReportingResults:

•200 Enterprise Apps well controlled

•Runtime Visualization

•Autonomic Control

•No Change to Existing Systems

•Higher Availability Achieved

WebSphere eXtreme ScaleRealizing high performance, scalable for data-intensive applications

It can be used as a very powerful cache that

scales from simple in-process topologies to powerful distributed

topologies.

It can be used as a platform for building

powerful XTP/Data Grid applications.It can be used as a form of

in memory database to manage application state (and it scales to 1000’s of

servers). This is sometimes referred to as

Distributed Application State Management.
