To complete the migration fast and minimize project complexity, RBI engaged Hitachi Digital Services. Through this collaboration, RBI aimed to capitalize on the proven capabilities, expertise, global footprint, and scalable team of Hitachi Digital Services to usher in transformation and add a sustainable edge to its operations.
Marek Chlebicki adds: “It was crucial for us to establish not merely an outsourcing relationship, but a genuine partnership. Our aim was to tackle challenges and navigate the path ahead collaboratively. This represented a departure from traditional models; we envisioned a symbiotic relationship, focusing on mutual goals, growth and understanding. We firmly believed this progressive approach was the optimal way forward.”
RBI worked with Hitachi Digital Services to execute a strategy encompassing four elements. In the initial Assessment phase, Hitachi Digital Services performed a deep-dive analysis of the ‘as-is’ state for all technical and functional components of applications used by RBI’s network of subsidiary banks. This enabled the formation of the target cloud architecture for each application, aligned with broad business objectives.
Then, in the Mobilization stage, Hitachi Digital Services crafted plans for the target operating model, configuration of Amazon Web Services (AWS) Virtual Private Clouds, landing zones, and security group structures.
For the Migration and Modernization process, RBI set up a dedicated Migration Factory function. Utilizing the AWS Migration Acceleration Program, this approach streamlined the transition, and enabled on-the-fly modernization work, such as replatforming and refactoring to optimize applications for the cloud from the start.
Furthermore, RBI inaugurated monthly AWS Immersion Days with the Hitachi Digital Services team, focused on topics that help to accelerate and standardize migration patterns and reinforce execution quality.
The new cloud environment harnesses a broad range of AWS services. For example, RBI modernized application workloads using container platforms such as EKS and ECS with Fargate, moved key databases to RDS for Oracle and RDS for PostgreSQL, and migrated storage to EFS and FSx. The bank also uses OpenSearch for data indexing, CloudWatch for application monitoring, and Security Hub, KMS, and WAF to protect the environment.
In the fourth element of the strategy, Hitachi Digital Services helped to launch a dedicated training initiative, involving workshops, learning sessions, and hands-on experiences for RBI employees. This process equips users with the skills required to operate effectively within the new AWS cloud ecosystem.
