Hi All,
We provide a web based service. Currently, we have one web server, and one backend MySQL server on two physical servers.
What we need is to be able to provision additional web or sql servers as demand grows, or shut them down again as demand decreases. We would also like to be able to deploy test machines as required or "demo" machines as required. This is why I am looking at the Ubuntu cloud approach.
This leaves us in the situation that we have no failover or scalability.
Is the Ubuntu Cloud a good solution for this situation? If so, can anyone give me some pointers as to the correct hardware configuration to achieve scalability as well as failover/loadbalancing?
From my initial look through the Ubuntu Cloud site, I would suspect that we would need.
3 physical machines and one shared data store - NAS/SAN?
one server would be the Cloud Controller, booting off local disks
The other two machines, booting off local disks but using the external storage for vm's as a cluster.
Thanks in advance,
Leslie
