       In Last post , we discussed about what is cloud ? This post discussed about how it differ from On-premise.

     As we know, All IT companies are going for cost cutting, but they won't compromise security and availability of resource for their customers. In this situation cloud service companies started around 2010.

What cloud does?
 
     Very good question, what it does, simply it working as on-premise server only  except all the services provided via internet, Services means request, response especially User Interface . So, the cloud data and cloud resource have to store somewhere in the on-premise only.
    
     Companies have to focus only on their customer business functionality and will get what they want, they no need worry about hardware, softwares, servers, Data storage process especially security mechanism like anti-virus, firewalls and so on.

    The following are cloud categories with service offered company.

  Software As a Service (SaaS)

     - Salesforce.com, Sugar CRM , Zscalar (Security) Products , Eloqua , SAP  and so on.

 Platform As a Service (PaaS)

    - Salesforce Force.com, Google App Engine, Windows Azure, Amazon Web Service , RightScale  and so on.

Infrastructure As  a Service (IaaS)

  - Amazon (Famous one ), CA Technology , Hp  , GoGrid and So On.

Apart from in emerging Cloud services like Data As a Service, Security As a Service and So on.

One thing we need to remember the Word “On- Demand “which means whenever you need. For example some software or business is for only short term like marketing some products only on summer.
