Abstract |
: |
Recently, cloud computing has become one of the most interesting issues in information technology. The basic idea underlying cloud computing is to utilize shared and metered resources over the Internet. The need for cloud computing comes from the increase in highly distributed large scale systems, high performance computing, and the high cost of the large number of required resources. This new technology comes with the promise to overcome the high costs of resources management. Cloud computing offers easily provisioned, on demand services with less management required.
One of the critical obstacles in the adoption of cloud computing services is the service availability, which is one of the measures of cloud computing performability. Therefore, studying and evaluating the service availability helps both the cloud service provider and the customer.
The service availability may be affected by several factors like the failure of the resources that are used, the number of the resources used, and the number of competitors that compete for these resources.
Studies like these need referenced techniques to be used in their evaluation. Using analytical and simulation models helps to estimate the behavior of the systems, and in reporting the conclusions that are used in making those decisions.
Moreover, cloud computing services should be deployed in a high availability form. For the sake of high availability, service protection techniques can be used to preserve the original services.
This thesis studies and evaluates the service availability for the protection models in a hybrid cloud computing architecture. The author presents three studies including a one to one protection model, one to N protection model, and M to N protection model.
For each of the three protection models the thesis employs two referenced techniques, the Markov Chain and Discrete Event Simulation, to study and analyze the service availability, and to explain the impact of the factors that affect the service availability in each model. As a result, this thesis gives a classification of the impacts of these factors. |
