Cloud Computing Concept

There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing:

  • Deployment Models
  • Service Models

Cloud Computing Deployment Models

There are following types of deployment models:-

  • Public Cloud
  • Private Cloud
  • Community Cloud
  • Hybrid Cloud

Cloud Computing Service Models

The Three Types of Cloud Computing Service Models are :

  • IaaS – Infrastructure As A Services
  • PaaS – Platform As A Services
  • SaaS – Software As A Services

IaaS – Infrastructure As A Service

  • It provides only Infrastructure (i.e Servers, load balancer, Storage, Network etc) to clients.
  • The client needs to install our Operating systems and applications on those virtual machines.
  • It requires System Admin to configure the servers.

  • The client needs to install only applications on those platforms. No need to worry about maintaining platforms.
  • It requires Programmers to develop applications.

Providers: Google App Engine; Microsoft’s Azure Service; Force (SalesForce); etc.

SaaS – Software As A Service

  • A client doesn’t need to perform any task, just need to use the applications over the internet.
  • It requires only End users to use the applications, no manpower required by clients.

Networks: Sales-force; Google; SAP; Oracle; Microsoft; and many more.
