  HISTORY  Concept originatedfrom telecommunication companies changing to VPN.  1999: Salesforce.com – Delivery of application via web.  In 2002 Amazon provided first public cloud AWS (Amazon web service).  In 2006 Google docs etc.

  INTRODUCTION  Cloud computingis “Internet based computing”, where by shared resources, software and information are provided to computers and other devices on demand , like the electricity grid.  Cloud computing is a paradigm shift following the shift from mainframe to client-server in the early 1980s.Details are abstracted from the user, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud “ that supports them.

  TYPES OF CLOUDCOMPUTING
• 7.
  PUBLIC CLOUD  Publicclouds are made available to the general public by a service provider who host the cloud infrastructure. Generally, public could providers like Amazon AWS, Microsoft and Google own and operate the infrastructure and offer access over the Internet.  With this model, customer have no visibility or control over where the infrastructure is located.  It is important to note that all customers on public clouds share the same infrastructure pool with limited configuration , security protections and availability variances.

  PRIVATE CLOUD  Privatecloud is cloud infrastructure dedicated to a particular organization.  Private clouds allow businesses to host applications in the cloud, while addressing concerns regarding data security and control which is often lacking in a public cloud environment .  It is not shared with other organizations, whether managed internally or by a third party , and it can be hosted internally or externally.
• 9.
  HYBRID CLOUD  Hybridclouds are a composition of two or more clouds (private, community or public) that remain unique entities but are bound together offering the advantages of multiple deployment models.  In a hybrid cloud, you can leverage third party cloud providers in either a full or partial manner, increasing the flexibility of computing.  Augmenting a traditional private cloud with the recourses of public cloud can be used to manage any unexpected surges in workload.

  COMPONENTS OF CLOUDCOMPUTING 1.laaS(Infrastructure as a service): IaaS refers to computer infrastructure that’s delivered as a service. 2.PaaS(Platform as a service): Offer the run time environment or API for application. It also offer development & deployment tools, required to develop application. 3.SaaS(Software as a service): SaaS refers to software that’s made available as a web-based service.
