Is there any documentation, white-papers or guides on clustering?
I''m working on a HA load-balanced system where the DB back-end consists of a large MySQL cluster. The plan is to make the front-end HA load-balanced too, but I''ve been unable to discover any useful information on clustering multiple netkernel nodes - especially any caveats that might impact on the design of the netkernel applications.
The client-side is 95% AJAX so there''s a constant stream of requests arriving on keep-alive connections.
My gut instinct is that provided the session data is committed to the DB there shouldn''t be an issue, but I''ve a nagging feeling that I''m overlooking something.
I expect a cluster will scale almost linearly as nodes are added, which should mean we simply need to add nodes as demand increases.
The front-end needs to be able to sustain 100,000 requests per second from 50,000 unique clients and be able to grow from there.
