Green cloud computing is a trend which has become popular with the emergence of internet driven services in every field of life. It refers to the prospective environmental advantages that computer based internet services can guarantee to the environment, by processing huge amount of data and information from collective resources pool. The cloud computing is emerged as an effective substitute to a traditional office based processing of services.
What is Cloud Computing?
It is a system that permits a convenient means of network access as per demand, from a common pool of configurable computing means which can be swiftly provided and managed without much service interface or supervision. The cloud computing can be private or public, based on the requirements and enormity of the service. According to the expert researches, it is stated that the widespread usage of cloud computing can lead to a saving of around 38% of the global data centre energy outflows.
Given below are the major reasons of why cloud computing is environment friendly or greener, whether it is private or public:
Virtualisation of Resources , Enable Energy and Resource Efficiencies
Resources virtualisation is the key to cloud computing, in which a single physical server machine runs a set of operating system machines in different locations simultaneously. Such a set-up can drastically reduce the number of physical equipment requirement to process the workload, and hence the data hub space as well as the e-waste. It also reduces the number of physical servers required for processing the data and thus saves the electricity required to operate multiple machines.
Automation Software – Helps to Maximize Merging and Utilization
Along with virtualisation, the cloud based computing relies heavily on automation software to swiftly process, move and balance workloads. Software professionals optimize their infrastructure cost of cloud computing by expanding the limits of old-style linking and deployment ratios, by using the right automation software. When these ratios are higher, the physical infrastructure requirements are lesser and this will enhance the utilization of resources and energy.
Payment as Per Usage and Self Service
The cloud based system uses the pay as per usage method and this force the users to consume just what is needed and nothing more. This optimal usage united with self-service enhances life cycle management, as users will switch off the resources once their usage is over. This infrastructure of cloud computing can of enterprise the productivity of energy and resources due to optimal usage.
Multitenancy or Benefit for Many Units
A shared cloud computing infrastructure lets diverse business units in a public cloud to share the same resources from remote locations. In case of a private cloud system, the common resources are shares with different units in the same business organisation. This can lead to massive reduction in the cost of resources infrastructure as well as energy consumption by the various units involved.
It is indeed a great step for organisations to switch from usual processing of workloads to cloud computing system, in terms of both energy competence and sustainability objectives. Many IT organisations today are joining in the green cloud computing system in an attempt to preserve our valuable resources.
