What Are the 5 Main Types of Clouds Computing? Types of Cloud Computing

There are four main types of cloud computing: private clouds, public clouds, hybrid clouds, and multi-clouds.

Cloud Service Models

Cloud computing services have three main types: Infrastructure-as-a-Service (IaaS), Platforms-as-a-Service (PaaS), and Software-as-a-Service (SaaS).

Public Clouds

The public cloud refers to computing services over the internet by third-party providers, offering services that can be purchased or used by anyone interested. Users can access public clouds for free or on-demand, paying only for resources used.

Private Clouds

Choosing a cloud computing type is very crucial. Private cloud service is intended for single-use, resources found on-premises or a third-party operates offsite. When delicate data is involved, Federal agencies opt for personal clouds.

NIST lists five essential characteristics:

  1. On-demand self-service
  2. Broad network access
  3. Resource pooling
  4. Rapid elasticity
  5. Measured service
