Cloud computing is a
general term for the delivery of hosted services over the Internet. Cloud
computing enables companies to consume compute as a utility – similar to
electricity or a telephone service – rather than building and maintaining
computing infrastructures. The practice of using a network of remote servers
hosted on the Internet to store, manage, and process data, rather than a local
server or a personal computer the cloud. Cache as a service (CaaS) model is an
additional service to Infrastructure as a service (IaaS). The cloud server
process introduce, pricing model together with the elastic cache system. This
will increase the disk I/O performance of the IaaS, and it will reduce the
usage of the physical machines. The emerging cloud applications provide data
management services allowing the user to query the cloud data, paying the price
for the infrastructure they use. A virtual machine (VM) is a typical instance
of IaaS. Although a VM as an isolated computing platform which is capable of
running multiple applications, it is assumed in this study to be solely
dedicated to a single application; and thus, we use the expressions VM and
application interchangeably hereafter. Cloud services as virtualized entities
are essentially elastic making an illusion of “unlimited” resource capacity.
This elasticity with utility computing (i.e., pay-as-you-go pricing) inherently
brings cost effectiveness that is the primary driving force behind the cloud.
Caching technology improves the performance.
