Public Cloud enables easy access for the general public to systems and services. Cloud services are available via the Internet by IT heavyweights like Google, Amazon, and Microsoft.


Cloud deployment as a public cloud model has several advantages.

  • Effective cost: Since the public cloud shares identical resources with many clients, it is cost-effective.
  • Trustworthiness: The public Cloud uses many resources at several locations. If any of the resources fail, a different cloud can be used.
  • Flexibility: the public Cloud can combine smoothly and flexibly with the private Cloud.
  • Independence of location: Public cloud services are provided via the Internet, guaranteeing location independence.
  • Costing of Utilities: The Pay-Per-Use model is also used in the public Cloud, and resources are accessible as customers require.
  • High Scalability: Cloud resources from a pool of resources are available on request, i.e., they can be extended or downgraded as necessary.


Here are some of the public cloud model disadvantages:

  • Low security: data is hosted off-site in the public cloud model, and resources are openly distributed so that a greater level of security is not guaranteed.
  • Less adaptable: It is relatively less customizable than the private Cloud.
