Cloud computing


Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user’s data, software and computation.

Cloud computing refers to the use of Internet-based computing, storage
and connectivity technology to deliver a variety of different services.

There are many types of public cloud computing:
  • Infrastructure as a service (IaaS)
  • Platform as a service (PaaS)
  • Software as a service (SaaS)
  • Storage as a service (STaaS)
  • Security as a service (SECaaS)
  • Data as a service (DaaS)
  • Test environment as a service (TEaaS)
  • Desktop virtualization
  • API as a service (APIaaS)
  • Backend as a service (BaaS)
