1.	Liferay is by heart a portal solution with a very strong & active community behind it and an impressive clientele to prove its credentials.	Alfresco is an Enterprise Content Management Software which also has an equally powerful & vigorous community supporting it and an imposing set of customers using the software. This is again, the most admired ECMS solution available in today’s open source market.
2.	Liferay has been wonderful in handling portal problems and its scalability have been the main driver that helped itself to be adopted in a variety of business verticals. However, as since its primary focus has been a portal solution, the document and content management capabilities of this framework does not make it very much enterprise ready, and not at all extensible, specially if we compare it with proper document and content management systems. However, the collaboration features of Liferay are definitely quite powerful.	On the other hand, Alfresco has been fantastic as an Enterprise Document and Content Management solution. The framework’s architecture, functionality and extensibility makes it really the best choice for an enterprise business. Having features like customizable workflow, templated UI, user-defined data-types, powerful rules engine etc makes this one of the best ECMS solution. Conversely, since it is not intended to be a collaboration solution, these features are not very well provided.
3.	Good Web Interface	The Web interface is not at all suitable for business users.
4.	In case of Integrated Solutions iferay providing the portal environment	while Alfresco sits at the lower level of the stack supplying the content management services.
5.	support Single Sign On	support Single Sign On
6.	standard LDAP providers	standard LDAP providers
7.	Alfresco can be integrated in Liferay	Alfresco Web Script is a very great framework which makes this solution even more feasible and extensible. Web Scripts can be used as a pltaform of SOA architecture based solution as well as these can be used as standard JSR portlets deployed in Liferay.

10.	Liferay started out as a project for a local church and grew into one of the most popular open source portal systems around (in a very competitive portal market).	Alfresco’s heritage is in large companies like Documentum and Interwoven and they have quickly become one of the most recognizable names in open source content management.
