Question

Explain in detail virtualization techniques in cloud computing.

Answer 1

A virtualization solution can have different CPU management facilities, most of them rely on schedulers that support weighted shares and maxCPU limit. Some of them support minCPU limit and additional facili- ties. Therefore, capacity planning for each VM in large-scale scenarios is a challenge and requires additional guidelines[23] and expertise to properly set the configuration parameters and amounts which better match each workload. At the end, a VMM manages the physical hardware and it does not need to know which workload each VM is running in. Therefore, upper management layers can leverage the VMM facilities in order to implement application-aware resource managers. We are working towards a management layer for cloud computing providers. The challenge is to abstract virtualization facilities in order to support high-level application requirements at each of the physical machines.
