The development of information technologies and the expansion of the Internet have brought us to an environment, which is filled with huge amounts of information. A number of content management systems have appeared which aim to support the management of these large amounts of content. Many CMS solutions are currently based on client/server model with a central server for storage and management. However, such centralized systems lack scalability and reliability. P2P-based CMS solutions can solve the scalable problem, but they have some shortcomings such as security, reliability, etc. We present a P2P-based content management architecture (PCMA) with some grid properties such as security, reliability, etc., which combines the advantages of the above two models and avoids their shortcomings. PCMA can exactly discovery services and scales much better.
