As enterprise community looks at reducing their capital expenditure and at the same time increasing their productivity levels, the era of cloud computing is furthering moving deeper into the enterprise space. More and more enterprise are now living in a cloudy & virtualized world.
As far as cloud implementations are concerned, the starting point or the bottom layer is often the physical hardware – the servers in enterprise datacentres, whether owned by an enterprise or being provided by a service provider like that of Amazon or Google for public access.
Then it is virtualization. Virtualization is a technology that enables a single physical server to run many independent virtual servers simultaneously and is a very important component and an integral part of gaining the efficiencies that cloud computing can offer to an enterprise while running the datacentres.
Cloud and virtualization are automating the allocation of computing resources amongst the virtual servers and tracking end user (customer) resource use requires a management layer. This has heralded a new era that allows “true pay-as-you-go” billing which is part of the big bonus towards going in for cloud for the enterprise.
Cloud computing ecosystem also enables a set of services that allows users to tap the processing and storage capability of the overall cloud network. The cloud ecosystem does not stop here. Driving software delivery over the web, the provision of software (services) to end-users directed by the web is what has come to be known as Software as a Service.
This has driven a new software arena that builds a further layer – the software running in the cloud and being accessed by a lot of users through their browser. Cloud when clubbed with virtualization is today holding huge potential and is regarded by many as the next big thing in technology that will remain in action for a long time to come.
