Open source vs. commercial portals

January 30, 2012

A user uses an open source portal product, free of charge. User can modify and extend its
source code. Liferay Portal is an open source portal. It is distributed under the GNU, Lesser
General Public License (LGPL) (http://www.gnu.org/copyleft/lesser.html).
Liferay Portal is available in two versions: Community Edition (CE) and Enterprise Edition (EE).
A client can use its community edition, free of charge. If a client wants support from Liferay,
Inc., they can buy the Enterprise Edition.


You can study the source code of an open source portal to learn portal technologies (Refer
to https://github.com/liferay for the source code of Liferay Portal). A commercial
portal product is more expensive than the enterprise version of an open source portal. IBM
WebSphere portal and Microsoft SharePoint portal are commercial portal products.
This book is based on Liferay Portal Version 6.0. We will use this CE version to illustrate the
features of Liferay Portal and set up a sample website.
