The concept of cloud computing is quickly scaling the chasm between hype and reality. Cloud Computing is rapidly becoming popular amongst enterprises that realize the benefits of shared infrastructure, lowered costs and minimal management overheads. But not all organizations and applications may benefit from a cloud computing platform. A legacy application ported in a native fashion to a cloud computing platform may not utilize any of the platform’s USPs at all. More importantly, wrong choice of platform can be disastrous. Deciding the optimal cloud vendor or platform for your requirements is a complex task.
Consider the plethora of choices available in the world of cloud computing:
* Public Cloud or Private Cloud or Hybrid Cloud
* Infrastructure-as-a-Service (IaaS): Amazon AWS, Rackspace Cloud, GoGrid, Terremark,
* Platform-as-a-Service (PaaS): Google AppEngine, Microsoft Azure, Heroku
* Software-as-a-Service (SaaS): Salesforce, Netsuite, Google Apps, saas.com
* Should you use IaaS, PaaS or SaaS for your application?
* Which cloud database fits your application? SimpleDB, SQL, RDS, Hadoop?
