One of our clients, an offshore financial institution, split from their parent company and were required to migrate workloads, applications and data from an on-prem/cloud hybrid infrastructure to fully cloud-based, within a very aggressive timeline.
Sidero employed the Assess, Design, Build and Migrate framework to facilitate the programme of work. The initial activities involved understanding what the application landscape consisted of, including any and all interdependencies, infrastructure, user-access, and so on. The design aspect was a consultative approach with the client, building the To-Be state based not only on like-for-like, but also taking into account budgets, timelines & milestones, future operating models and resources/skills.
A fundamental aspect of this part of the engagement was analysing the most appropriate end-state for each application stack/workload, using the 6 R’s [Rehost, Re-Platform, Re-factor, Re-purchase, Retire or Retain]. Our consultative approach brought subject matter expertise to the project, allowing us to make sound recommendations to the client.
Once architectural design principles were agreed, we worked with the client to build the agreed operating environments for the necessary workloads. Due to the aggressive timelines involved, the optimal outcome involved re-hosting the majority of the applications, with some re-platforming involved. Subsequent programmes of work will involve optimising these workloads to take into account cloud-native features.
This programme was delivered out of Ireland for a non-Irish based bank with a North American AWS Region as the preferred hosting environment.
