Thread: autoscale cluster
hi everyone,
I'm looking for info about autoscale a cluster. I mean...with amazon you can generate automatically virtual machine as far as you need...if you configure that when the machine get 90% busy a new one will be created. The thing is that i'd like to do something like that for my database...whem my datbase get 90% busy...automatically another machine is created to share the charge.
I dont know if it is possible..can anyone give some piece of advice???
thanks

Auto-creating a new app server is a whole different idea than autogenerating another database server. An app server is a relatively independent processing unit. Requests go in, get processed, and results are spit back out. Each request is independent of the other requests. A database is a storage engine that ensures that each unit of information put into it fits within all the proper constraints of all the other data already in place, and that updates and changes happen in whole or none at all. How do you just "throw another db" at a problem? You cluster it. That's a complex problem to solve in comparison to app servers. > I dont know if it is possible..can anyone give some piece of advice??? You can most certainly using clustering to increase db performance for many work loads. Whether a certain method works for you or not depends on what you're doing. Making it automagically create new virtual cluster members sounds like a really cool feature that would make you pull your hair out developing it.
