I want to try Ubuntu OpenStack with Metal-as-a-Service (MaaS) for web application purposes. I would be using Apache2, PHP, MySQL and Postgres.
If I got 5 or more machines setup and installed all those application would it be able work as cluster, for parallel execution?
For example, would a MySQL insert of 1500 rows be able to execute using resources (RAM, CPU, disk, etc) from multiple machines in the cluster? For another example, if I got 1000 requests to the site, would Apache and PHP be able to use multiple machines to handle the requests?
Basically, could I use OpenStack to create a cluster that would perform a lot faster than a single server without OpenStack would?
