WSO2 Application Server architecture

lazy loading and resource management ?

• Application servers usually run for a long time, keeping inactive applications on memory for a long time can effect to performance.

• Application server restarting can cause considerable amount of application downtime and effect to availability.

• Resources such as memory, cache and processor time are expensive hence need better resource management.

• Lazy loading and resource sharing mechanisms should not negatively effect on end user experience.

lazy loading and resource management

• Tenant lazy loading.

• Web Service lazy loading.

• Web Application lazy loading.

Web Service lazy loading.

Web Application lazy loading.

Clustering and session replication

• The ability to store session specific data in Web services is an important feature.

* Supports 3 levels.

ServiceContext level.

ServiceGroupContext level.

ConfigurationContext level.

• AppServer clustering is based on the Apache Tomcat Tribes group management system.

Deployment Synchronization

• Used to synchronize the main repository of a Carbon server with set of nodes.

• Usually one READ-WRITE repository with number of READ-ONLY repositories.

• Offer two different approaches.

* SVN based synchronizer

* Registry based synchronizer

Deployment Synchronization

WSO2 Carbon features with Webapps

• Carbon Webapp which is running on Tomcat.

• Other webapps are also deployed in parallel with the Carbon Webapp.

• Some API’s are shared across all Webapps to make important Carbon features available for external Webapps as well.

* Authentication

* Registry (Metadata Repository)

* Carbon Caching

WSO2 Carbon features with Webapps

Carbon Authentication for Webapps

• All Carbon functionalities are implemented as Web Services which are called Carbon Admin Services.

• AuthenticationAdmin Service handles all Authentication functionalities.

• AuthenticationAdminClient API is provided to talk to the Admin Service.

• Webapps can use that API to communicate with the Carbon User store.

• Any User store can be plugged into Carbon (Default LDAP)

Registry for Webapps

• WSO2 Registry is used by all WSO2 products as a metadata repository

• Webappsalso can use it for the same purpose through the CarbonContextAPI

Web service development

• SOAP 1.1/1.2 and RESTfull Axis2 web services.

• JAX-WS 2.2 web services and JAX-RS services.

WSO2 Developer Studio based development

WSO2 Developer Studio

WSO2 Developer Studio is the development

tool for writing applications that get hosted on

one or more of carbon servers.

• This is based on the popular Eclipse IDE with all the familiar tools at hand.

• Developer Studio contains diverse set of tools

vital for configuring your enterprise architecture

Jaggery.JS support

A completely Javascript way of writing all parts of the Web applications and services. Closes the gap between Web apps from Web services by allowing one to create both applications and

APIs at the same time.
