CLOUD COMPUTING

 Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over anetwork (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.

There are many types of public cloud computing:

• Infrastructure as a service (IaaS)
• Platform as a service (PaaS)

• Desktop as a service (DaaS - see above)
• Database as a service (DBaaS)
• Test environment as a service (TEaaS)
• API as a service (APIaaS)
• Backend as a service (BaaS)
• Integrated development environment as a service (IDEaaS)
