Cloud Computing

Cloud computing lets businesses outsource server and storage resources to trusted third-party vendors with pay-as-you-go pricing.

Prescio can help you choose the appropriate cloud computing vendor, reduce IT costs, design systems for your applications, and train your team to maintain the different systems and storage services.

The service models of cloud computing

  1. Software as a Service (SaaS): Consumers can access applications via thin clients such as web browsers. They have no control over underlying infrastructure such as operating systems and servers.
  2. Platform as a Service (PaaS): Consumers can develop their own applications using programming languages, libraries, databases and tools that the cloud service provider supports. The consumers cannot change the underlying operating systems and servers.
  3. Infrastructure as a Service (IaaS): Consumers are given the computing infrastructure such as virtual machines and storage to configure their own operating systems and deploy custom applications.

The deployment models of cloud computing

  1. Private Cloud: Access to cloud infrastructure as the name implied is limited to a particular organization. Management of such infrastructure can be done by the organization, the service provider, or jointly.
  2. Community Cloud: Access to cloud infrastructure is open to sanctioned organizations sharing a mission, a cause, or location. Management of the infrastructure can be done by any or all of the organization onboard.
  3. Public Cloud: Access to cloud infrastructure is open to the public and managed by organizations that provide access such as government or universities or by the cloud service provider.
  4. Hybrid Cloud: This type of deployment refers to infrastructure being composed of a mixture of private, community and public cloud. They remain distinct entities but share a standardized platform which enables portability of applications and data.
