—Cloud Computing aims to provide reliable services within data centres that contain servers, storage and
networks. The services are delivered to the users transparently without their need to know the details of the underlying
software and hardware. One of the challenge of cloud computing is to ensure that the applications run without a hiatus
in the services they provide to the users. In most of the real time cloud applications, processing is done on remote
cloud computing nodes. So there are more chances of errors. Also, the correctness of the applications running on the
system depends not only on the logical result, but also the time it was delivered. Failure to respond is as bad as the
wrong response. These systems have two basic characteristics that is Timeliness & Fault tolerance. For this purpose,
we have presented a model for the fault tolerance of systems that mainly determines timeliness of the output and
reliability of the systems. Our proposed method identifies the fault based on the resource availability of Virtual
machines (VM). The reliability of the VM can be identified based on the response time or resource availability. The
resource availability is the one of the proposed techniques used in this paper.
