Cloud services
Cloud services refer to any IT services that are provisioned and accessed from a cloud computing provider. This is a broad term that incorporates all delivery and service models of cloud computing and related solutions. Cloud services are delivered over the internet and accessible globally from the internet.
Cloud services provide many IT services traditionally hosted in-house, including provisioning an application/database server from the cloud, replacing in-house storage/backup with cloud storage and accessing software and applications directly from a web browser without prior installation.

There are three basic types of cloud services:

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

Cloud services provide great flexibility in provisioning, duplicating and scaling resources to balance the requirements of users, hosted applications and solutions. Cloud services are built, operated and managed by a cloud service provider, which works to ensure end-to-end availability, reliability, and security of the cloud.
