When you plan to build an amazing website based on a portal, you may commonly consider a lot of questions. Some of them would look like the following:
- Are you planning to build a website with an open source enterprise portal solution using SOA framework, ESB and Web 2.0 technologies?
- Do you want to add collaborative tools, such as Wikis, Blogs, Discussion Forums, Shared Calendar, RSS, mail, Tagging, and instant messaging in the same website?
- Do you want to manage, publish and maintain web contents and documents in the same website?
- Are you eager to integrate with LDAP, SSO and third-party systems like JBoss jBPM, Alfresco, Orbeon Forms, and Pentaho BI/Reporting in the same website?
As the world's leading open source portal platform, Liferay provides a unified web interface to data and tools scattered across many sources. Within Liferay portal, a portal interface is composed of a number of portlets—self contained interactive elements that are written to a particular standard. Since portlets are developed independently of the portal itself, and loosely coupled with the portal, they are apparently SOA (Service-Oriented Architecture).
