These data centers require a regular monitoring, maintenance and investments to assure its functionality with effectiveness to serve the enterprise business goals. The existing knowledge revealed many operational, scalability and cost challenges that faces enterprise’s IT services. To overcome these challenges, the enterprises can adopt Cloud Computing services to achieve high levels of scalability, while making IT services accessible to all users at reasonable infrastructure costs and on-demand. Considering the known security and operational risks, the Hybrid Cloud Computing deployment model can be the optimum model for large enterprises. For conducting the transition from on-premises IT infrastructure to a hybrid cloud computing model, an effective migration framework is crucial for a successful migration. Literature review presented the known migration types, methods and frameworks that can be followed in cloud computing migration scenarios. Famous migration methods and frameworks have been discussed and compared. The research shows that typical information technology systems and applications, can be migrated to a Hybrid Cloud Computing model using the standard migration framework for Cloud Standards Customers Council (CSCC). This framework has shown superiority over the other frameworks in the scanned literature. This research also discusses the implementation of the proposed framework in an Egyptian enterprise’s case study, including a business case with cost analysis, developing the technical approach, the compliance, and the security requirements. This is in addition to considering the business and technical concerns, and finally the migration steps with IT infrastructure necessary modifications prior migration. | |
