Objectives
The company needed to develop a new digital platform to support their banking business. They had a complex infrastructure, including x86 workloads, a UNIX estate, and two mainframes running several core banking business products. The need to improve speed to market was crucial for this customer while ensuring they remained compliant with strict Financial Conduct Authority guidelines.
Key objectives:
- Exit the existing data centre and retire legacy technology where possible.
- Formulate a strategy to exit mainframes and modernise products.
- Improve security controls to maintain regulatory compliance.
- Develop a new application platform for product development.
- Improve technical debt position across the portfolio.
Approach
- Data ingestion of customer assets including, application and infrastructure data.
- Rapid discovery and assessment and cloud strategy development, including 25 different migration grouping scenarios.
- Migration strategy and roadmap underpinned by applications and infrastructure data.
- Rapid mapping of workloads to one of the six R transformation methods
- A Migration Readiness Assessment has been performed, the assessment covered the following areas, Governance, People, Operations, Security and Platform.
- Creation of a full business case including, operations, infrastructure and facilities costs for comparison to future cloud costs.
- Development of mainframe migration strategy and business case, multiple scenarios.
Results
- Rapid discovery and assessment and cloud strategy development, enabling first migrations in under 45 days.
- Migration ASIS and TOBE architectural model, including technology, treatments and landing zone identification for x86 and UNIX workloads.
- Migration ASIS and TOBE architectural design for mainframe modernisation, including rehosting into cloud or modernisation of specific services to cloud native technologies.
- Migration risk analysis and mitigation report.
- Compare migration costs between AWS and Azure.
- Detailed database analysis of their existing Oracle workloads for potential adoption of Azure native database services.
- Business case development, including ASIS costs, migration costs and future operational costs, including cloud infrastructure services, modelled over five and 10-year timelines.

- Industry: Financial Service
- Size: Large
- Location: United Kingdom
Key Metrics
- 6 files were ingested
- 10 elapsed days to complete
- 13 Scenarios were created
Objectives
The customer’s main objective was to move to the cloud across their estate whilst also reducing their footprint in its on-premise data centres.
Key objectives:
- “Cloud First” objective as well as a goal to reduce its footprint in its On-Premise Data Centres
- Emphasis is on the closure of 4 main sites
Approach
- Working with a service integrator already appointed by the customer.
- Junkshon team analysed the source data and determined that the most appropriate migration scenario, in this case, would be to split and present the data by Operating System
- Production of a cost model with greater accuracy given OS to server mapping was available
- Clear view of migration treatments and enabled the production of the Migration Flight Plan
Results
- The primary migration method is Platespin for the rehosting and re-platforming activities
- The recommended target state is IaaS on Azure
- Azure supports running industry-standard Linux distributions, including CentOS, Debian, Red Hat Enterprise, Ubuntu, and FreeBSD
- We recommend that to get the most value from utilising the cloud, priority should be given to the Rehost projects, allowing time to prepare and execute the Replatforming elements
- It is clear there is a desire to migrate application by application. Considering a deeper dive analysis on the 70 client/server applications identified by the Customer and how they align to the OS level breakdown provided by Junkshon
