Abstract:
Large Enterprises have its own information technology systems
running on their owned data centers. 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.
