Types of Cloud Services

Cloud Service Models

On-demand cloud services are of mainly three types:

  • AWS EC2
  • Google Compute Engine (GCE)
  • Digital Ocean
  • The user can modify the architecture as per their requirements since it is basic cloud infrastructure.
  • The user has full control over all the computing resources.
  • Windows Azure
  • OpenShift
  • AWS Elastic Beanstalk.
  • It is a simple model to use and deploy applications.
  • Low cost: Since the platform is already built, the user needs to create only their applications. This reduces the costs related to hardware and software.
  • Platform restrictions: The platforms provided by some vendors may have certain restrictions, for instance, the user can use only certain specified languages.
  • Google Apps
  • Salesforce
  • Dropbox.
  • There are two modes of SaaS:
  • Simple Multi-Tenancy: Each user has independent resources that are different from the resources of other users.
  • Fine Grain Multi-Tenancy: Resources are shared by several users but the functionality of these resources remains the same.
  • Low maintenance: Users need not update an application. The application is on the server, and it is the service provider’s responsibility to maintain the application.
  • Quick setup: Users do not require any hardware to install the application. The SaaS application is already present on the cloud.
  • Connectivity issue: The applications can only be accessed only via the Internet. Hence, if there is no Internet, then the users cannot access the applications.
