cloud computing

In this post at poly-technology at blogger we are going to tell you what cloud computing is and why the businesses should join cloud computing for their services and not to build data centers at their company to host their data because this way it is more expensive then hosting their data in cloud computing.

Businesses can not be distracted from their objective , by their purpose . But , of course, in this case appeared skeptics suspecting that a company can provide business data and these data can not lose . Cloud Engineers Petrovic: answered skeptics by developing these powerful techniques for data security , such as encryption .Since the technologies including the Internet , web browsers -at ,virtual servers , and software parallelism open source are combined have brought a set of options to get more products from computers .The term cloud computing is a concise description of these combined technologies .

" Cloud " in the term cloud computing is a metaphor for computational resources ( computing resources , hardware and software ) to access the companies and users without the need to know exactly , where they are physically located hardware and software .

In the second part of the diploma addressed two very important elements for cloud computing as live migration and data backup . Before we did the live migration should definitely clarify the virtualization . Virtualization is a key technology that enables operation of cloud computing because it allows the resources accessed by different applications depending on the requirements and hides the complexity of resource allocation from the cloud 's users .

If a virtual machine is an application executes its CPU stops or charged more , then the application can be migrated from one virtual machine to another . Migration of live virtual machine includes the transfer of memory pages that were working with , the transfer of resources that are participating in this application ( network card , disk , etc. . ) And CPU status . Each virtual machine has its CPU , its physical memory ( which is shared between virtual machines ) , I / O , etc. 

Data backup is very important in the cloud , as the company requires that their data are not lost for any reason . For this reason, depending on the contract i'u providers make data backup client . These data should not only be stored in a data center but must have a data synchronization with another center . 

This technique should be performed as in the case of any natural destroying the first center of this information will have the opportunity to do the backup . Backup of data should be in place between the same center servers to data storage . So if a server falls within this center should unquestionably be restored data .
