Case Study: FAB Bank's Two-Phase Migration to the Cloud Introduction; FAB Bank is a financial institution that operates in the United Arab Emirates and has multiple software applications, including a core banking system, archiving system, e-payment system, ATM switch, and human resource management system. The bank is planning to move its systems to the cloud in two phases to minimize risk and take advantage of the benefits of cloud computing. Phase 1: In the first phase of migration, the bank should prioritize moving its less critical applications to the cloud, such as its internal archiving system and human resource management system. These systems are less essential to the bank's day-to-day operations, and any downtime or issues during the migration process would not have a significant impact on the bank's operations. Service Models; for these less critical applications, the bank should consider using infrastructure as a Service (laaS) and Software as a Service (SaaS) models, which will provide the bank with the necessary computing resources and storage for these systems, without the need for the bank to manage the underlying infrastructure. Deployment Models; For the first phase of migration, the bank should consider using a public cloud deployment model, as this will provide the bank with the lowest cost option for these less critical applications. This will also provide the bank with the ability to take advantage of the economies of scale provided by a public cloud provider. Risks: The main risks associated with this phase of migration include data privacy and security, as well as the need to ensure that the bank's data is stored and managed in a compliant manner. To mitigate these risks, the bank should ensure that the cloud provider is following all relevant regulations and standards, and that the bank's data is encrypted and stored in a secure manner. Benefits: The benefits of this phase of migration include reduced costs, increased scalability, and the ability to take advantage of the latest technologies. Additionally, moving these less critical applications to the cloud will allow the bank to focus on its core operations and reduce the burden of managing and maintaining these systems. Phase 2: In the second phase of migration, the bank should prioritize moving its critical systems; such as its core banking system, ATM switch, and e-payment, to the cloud. These systems are essential to the bank's day-to-day operations, and any downtime or issues during the migration process would have a significant impact on the bank's operations. Service Models: For these critical systems, the bank should consider using Infrastructure as a Service (laaS) and Software as a Service (SaaS) models, as these models provide the bank with the necessary software and platforms, while still ensuring that the bank maintains control over the data and configuration of these systems. Deplovment Models; for the second phase of migration, the bank should consider using a hybrid cloud deployment model, as this will provide the bank with the necessary level of control and security for its critical systems, while still allowing the bank to take advantage of the benefits of a public cloud. Bisks: The main risks associated with this phase of migration include downtime, data privacy and security, and compliance with regulations and standards. To mitigate these risks, the bank should ensure that it has a comprehensive migration plan in place, that its data is encrypted and stored in a secure manner, and that the cloud provider is following all relevant regulations and standards. Benefits: The benefits of this phase of migration include increased efficiency, scalability, and the ability to take advantage of the latest technologies. Additionally, moving these critical systems to the cloud will provide the bank with increased flexibility and reduced operational costs, as the bank will no longer need to maintain and manage these systems on-premises. Conclusion: The migration of FAB Bank's systems to the cloud is a significant undertaking, but it has the potential to provide the bank with numerous benefits, including reduced costs, increased efficiency, and the ability to take advantage of the latest technologies. By following a phased approach to migration, the bank can minimize risk and ensure a successful transition to the cloud. Case questions: 1.
