WSO2 Application Server is an open source, multi-tenant application server that provides scalable web services and web application hosting. It is built on the WSO2 Carbon middleware platform and supports standards like SOAP, REST, and JAX-WS. Key features include lazy loading, clustering, caching, and integration with the WSO2 identity server. Developers can use WSO2 Developer Studio for configuration and development. The application server also supports Jaggery.js for writing web applications and APIs in JavaScript.

12. WSO2 Application Server architecture

13. 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.

14. lazy loading and resource
management
• Tenant lazy loading.
• Web Service lazy loading.
• Web Application lazy loading.

15. Web Service lazy loading.

16. Web Application lazy loading.

17. 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.

18. 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

19. Deployment Synchronization

20. 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

21. WSO2 Carbon features with
Webapps

22. 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)

23. 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

24. Web service development
• SOAP 1.1/1.2 and RESTfull Axis2 web services.
• JAX-WS 2.2 web services and JAX-RS services.

25. WSO2 Developer Studio based
development

26. 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

27. 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.
