Clustering is mentionned here http://www.virtualizor.com/tour but without much details.
Is it like clustering found in some control panels ?, ie :
All
shared-hosting services are normally placed on one physical server.
This approach has proven its stability, but has a number of drawbacks.
For example, it does not provide high availability and scalability.
Failover.
Different kinds of services and tasks are distributed among several
machines, and when one of them fails, it does not affect the whole
system. In case of failure, everything you need is to change one server
into another.
Scalability. As the number of your
clients and/or load they create grows, you simply add new servers into
the cluster. The redundancy and the fall are not enough. When one of
the servers of a cluster breaks down, the session PHP stored in the
computer has to remain accessible to the other servers. Otherwise, the
end user will see his interrupted transactions(deals), his emptied
baskets of purchase and his lost work.Suggestion here is to bring PHP
sessions clustering with the help of an easy clustered db, i propose
couchbase for that task.
Single entry point.
Unlike a traditional approach "many servers - many control panels", all
the servers can be managed through a single control panel.
- Server status and events through a gui console
- Single configuration management for all servers regarding web servers and PHP.
- Capacity to add or suppress a server from the cluster, taking into account the sessions to redistribute.
