Cloud

Cloud Computing as a service over the Internet with defined characteristic such as
  • Virtual
  • Flexible and scalable
  • Elastic resources
  • Pay for use
  • Self Service
Public cloud : Owned and operated by companies that use them to offer rapid access to affordable computing resources to other organizations or individuals. With public cloud services, users don’t need to purchase hardware, software or supporting infrastructure, which is owned and managed by providers.
Private cloud : Dedicated to company that controls the way virtualized resources and automated services are customized and used by various lines of business and constituent groups. Private clouds exist to take advantage of many of cloud’s efficiencies, while providing more control of resources and steering clear of multi-tenancy.
Hybrid cloud : Combined with the strategic use of public cloud services. The reality is a private cloud can’t exist in isolation from the rest of a company’s IT resources and the public cloud. Most companies with private clouds will evolve to manage workloads across data centers, private clouds and public clouds—thereby creating hybrid clouds.

SaaS – Software as a service : run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the Internet and, usually, a web browser.
PaaS – Platform as a service : provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications—without the cost and complexity of buying and managing the underlying hardware, software, provisioning and hosting.
IaaS – Infrastructure as a service : provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.
