Cloud Computing Components and Market Statistics

December 3rd, 2011 by

I attended the IBM Cloud Symposium for IT Architects/Managers this week; it brought together a cross-section of Cloud professionals, including industry analysts, social media influencers, corporate clients and IBM global experts. It included discussions, panels and an interactive round-table that shared Cloud best practices, examined common pitfalls, introduce solutions and looked at key strategies for seizing the Cloud business opportunity.

The three areas of focus in the presentation were Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). This blog is going to share the definition of SaaS, IaaS and PaaS and share some Cloud Computing growth statistics.

What is Cloud Computing?

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet). Three examples of Cloud Computing are Software as a Service, Infrastructure as a Service and What is Platform as a Service.

What is Software as a Service (SaaS)?
Software as a service (SaaS, typically pronounced [sæs]), sometimes referred to as “on-demand software,” is a software delivery model in which software and its associated data are hosted centrally (typically in the (Internet) cloud) and are typically accessed by users using a thin client, normally using a web browser over the Internet.

What is Infrastructure as a Service (IaaS)?
Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it.

What is Platform as a Service (PaaS)?
Platform as a service (PaaS) is a category of cloud computing services that provide a computing platform and a solution stack as a service. PaaS offerings may include facilities for application design, application development, testing, deployment and hosting as well as application services such as team collaboration, web service integration and marshalling, database integration, security, scalability, storage, persistence, state management, application versioning, application instrumentation and developer community facilitation. These services may be provisioned as an integrated solution over the web.
