title: Pitfalls associated with moving a physical Cassandra cluster to a cloud based cluster?
body: <p>We're discussing transitioning our physical infrastructure to a cloud based solution, for a number of reasons, but a major one is so that we can scale out much more easily, along with all of the other "not having to host/maintain physical hardware" benefits you get with a cloud solution.</p>
  
  <p>That said, with Cassandra being a shared nothing architecture, what kind of performance hits will we most likely experience?  For starters we'd be sharing physical resources most likely storage, etc so how big an impact could this potentially be?</p>
  
  <p>I know companies like NetFlix have large cloud based cassandra clusters, but I'm assuming with their budget they can afford to have their stuff sitting on its own hardware and not sharing anything with any other companies...we obviously don't have that kind of budget.</p>
  
  <p>Just trying to get an idea of any major pitfalls to look for now, especially from anybody who has successfully done a migration like this.</p>
