Aaxsys Cluster Architecture

Aaxsys clustering is based on two fundamental decisions. First, each request to Aaxsys servers is atomic. This means that any member of the web cluster can handle the request independently, without consulting the database or other servers. The request already contains all information needed for its processing. Each cluster member being identical with respect to Aaxsys, it does not matter "through" which member the request goes. Each cluster member only needs to communicate with the database in order to process the request.

Secondly, all updates are synchronized through Aaxsys itself. Instead of relying on an external clustering software, or scheduled updates, Aaxsys modules themselves are written to do all file updates etc. in a synchronizing manner.
