A Method for Increasing Modifiability in Enterprise Architecture Implementation Using Cloud Computing

Present period is overflowing of continues changes that have been occurred in business environment and technologies to business. Organizations for following their practices are forced to manage these changes. Changes management in organization requires tools that one of those is enterprise architecture. It is a tools to manage business changes around technologies. But if enterprise architecture itself as tools for changes management has not have due efficiency and flexibility, it should be a barrier to progress the changes. Thus, it is required to make method and tools to increase modifiability in enterprise architecture. Therefore, tools and methods that are flexible make easier and more flexible to achieve the objectives and changes ' management become easier. In recent work, using cloud computing and service oriented architectures Proposed an algorithm to implement EA. then mapping supports this implementation and shows the documents for it. Cloud computing as a modern field of involvement quickly and is one of the most prominent feature cloud computing is flexibility. Now if it has been applied as a device in EA it will surely enhance flexibility in EA. As a result, EA and cloud computing should be joined in a suitable method. Business, data and application layer as whole, designing and logic in implantation of EA should be considered and in architectural layer of technology it is address in the implementation's details. Thus applying cloud computing has been investigated in this layer to implementing EA. certainly ,for having modifiable architecture ,it is required to design modifiability in Business layers data and application as well. It can transfer changes in this layer appropriately to technological one. Meanwhile, using service oriented architectures is beneficial. In a similar work, there is different architecture for measuring modifiability AHP method is proper to evaluate in terms of all criteria. In this article, Proposed method are compared with similar those of implementing EA. Obtained results indicate modifiability in implementing EA by cloud computing.
