In cloud computing, you do not have to be in a particular place in order to get access to information, data, tools or applications, which are stored in clouds. Companies that engage the services of cloud computing can actually reduce the costs in information management because they do not have to procure servers, although having your own servers is an option. In off-site servers, companies lease the servers from cloud computing service providers that are also the third parties.
As technology continues to advance, the carbon footprints, along with varying energy levels become more widespread, aggravating the already acute global warming. But cloud computing is different. It supports the green technology planning in the following manners.
Cloud computing arrangement adopts virtualization and companies in taking advantage of its benefits can save huge when it comes to energy costs: application management may be outsourced to cloud service provider and the internal servers may be reduced.
On the other hand, from the cloud provider’s end, the use of energy can be centralized and become more efficacious by supporting several cloud clients with application and server capacity services like the Software-as-a-Service or SaaS.
And since in Saas is a pay-as-you-use model, it allows businesses to select only the particular applications they require at a given time, in contrast to paying for the whole suite of applications or software on their area.
The staff needed for IT purposes for off-site servers may also be reduced as the cloud computing provider shoulder the expenses and responsibilities for managing and maintaining the servers.
There are several cloud computing service providers that use green energy to power up their servers. Instead of using fuel, many cloud-hosting providers now use wind, hydro or solar power as a component of their energy resources. In the United Kingdom and some countries in Europe, hosting companies are already use green power.
Flexibility In Computing
In Infrastructure-as-a-Service cloud or IaaS, cloud providers give adjustable computing power to organizations without asking them to provide some in-house hardware services. In a IaaS setup, the cloud computing providers furnish the needed infrastructures for their clients to run their applications.
IaaS scales the processing power to avoid the situations of overload, while averting the expenses needed for the under-used capacity. Similar to Saas, the IaaS also lowers costs for IT staff.
Virtualization on itself does not maximize resource and energy efficiencies. In order to move or scale the workloads, cloud computing service providers commit to automation software. Software automation enables IT experts push maximize the traditional utilization and consolidation ratios.
When the ratios are higher, the lesser are the physical infrastructures needed. As a consequence, the resources and energy efficiencies are maximized from virtualization.
Multi-tenancy enables various organizations or business units in one organization to enjoy the advantages of using or sharing from one cloud-base infrastructure. When demand patterns are combined from several business units and organization, the ups and down in compute requirements are flattened out.
