Cloud Service Attributes

Cloud computing is the delivery of on-demand computing services -- from applications to storage and processing power -- typically over the internet and on a pay-as-you-go basis. In cloud computing, rather the owning their own computing infrastructure or data centers, organizations can rent access to anything from applications to storage from a cloud service provider.
 
There are certain attributes that service has to provide before it can accurately be calleda  cloud service. Here are a few attributes.
 
 
  • Self Service
    Here the user should be able to get service by making an online payment and then accessing it via online too. These services should be on an on-demand basis.

  • Pay Per User
    User should be allowed to use some features of services without any cost; i.e. some features of the services should be free so that any user can use it to explore before actually buying it.

  • Elastic
    User should be allowed to provision/de-provision their resources as and when needed. It’s not only about the resourcses but the billing model should also be elastic.

  • Scalable
    User should be able to scale resources up or down as per Internet speed.

  • Fully Virtual and Automated
    Services should be fully automated. User shouldn’t be allowed to access physical infra/layer of the services. Instead he should be given access to the simulated layer of that physical layer.

  • Multi-Tenant
    Cloud service should support a multi tenant model; i.e., multiple users should be able to access the same application without compromising safety/security and privacy of the user.
If any of the above attributes are missing, organizations cannot say that the service they provide is a cloud service. And also, users should be aware of  these attributes before buying any service.
