A tribute to Clouds…

No page on Cloud Computing can start without a proper tribute to Clouds, “bows and flows of angel hair, and ice cream castles in the air, and feather canyons everywhere…”

Cloud Computing

Cloud Computing (from Wikipedia) is the use of computing resources (hardware and software) that are delivered as a service over a network (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 cloud computing:

• Infrastructure as a service (IaaS)
• Platform as a service (PaaS)
• Software as a service (SaaS)
• Storage as a service (STaaS)
• Security as a service (SECaaS)
• Data as a service (DaaS)
• Test environment as a service (TEaaS)
• Desktop as a service (DaaS)
• API as a service (APIaaS)

With this business model, using software as a service, users also rent application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run.

End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user’s data are stored on servers at a remote location. Proponents claim that cloud computing allows enterprises to get their applications up and running faster, with improved manageability and less maintenance, and enables IT to more rapidly adjust resources to meet fluctuating and unpredictable business demand.

Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.

The Electrical Engineering and Computer Sciences College of Engineering at Berkely has produced a wonderful Introduction to Cloud Computing covering both the technical and the economical aspects.
