Case Studies - Cloud Adoption Programme

Client

Cloud Migration Solutions were the technical delivery partner with another of the Department for Educations technical associates.

Requirements

  • Produce and implement a cloud first digital strategy.

  • Design with future hybrid/native cloud strategies in mind.

  • Design and implement a dedicated cloud hosting platform.

  • Design and implement on-premise hosting capabilities.

  • Exit expensive physical third-party hosted data centres.

  • On board 125+ workloads into the cloud and non-cloud compatible workloads into on-prem hosting.

  • Upgrade out of support OS, Middleware and Application components.

  • Produce a Continuous Service Improvement (CSI) log.

  • Reduce the time of business and digital strategies deployment to market.

Challenges

  • Complex, high-profile and politically sensitive programme of works.

  • The end-client had adopted a cloud first digital strategy; however, still had critical citizen services and core business workloads hosted on out of support infrastructure in third-party data centres.

  • Multi-vendor programme and resource augmented capacity profile.

  • Manage costs, RAID and functional / non-functional requirements.

  • Aggressive timeframes due to hosting contract renewals and out of support technologies.

  • Out of support technology stack.

  • Out of date workload design and build artefacts.

  • Fundamental issues with technical and security debt.

  • Issues exacerbated with a convoluted cloud hosting landscape.

​​

Activities

  • Discovery of the legacy technical estate and identifying key information, high risk issues recorded in RAID and technical debt registers, trends from service desk incident, major incident and requests.

  • Produce a workload strategic roadmap of where, when and how it would be on boarded into the cloud based on its business priority and activity.

  • Produce a full transformation cost analysis and risk reduction profile for each of the workloads.

  • Produce a series of updated build and passport, high- and low-level design artefacts.
  • Design and build a dedicated Azure hybrid-cloud hosting platform.

  • Design and build on-premise hosting capabilities for workloads that were not cloud compatible..

  • Attain authorisation of the design and supporting artefacts by the end clients Technical Design Authority.

  • Implement DevOps CI/CD pipelines for repeatable deployment and testing.

  • On board 125+ workloads from on-prem in to the cloud using migration and transformation techniques.
  • Provide early life support and handover into BAU.

Delivery

  • Operated at C-Suite level and chaired programme boards,

  • Agile, MSP and PRINCE2 disciplines.

  • Lean Six Sigma productivity best practices.

  • ITIL service delivery.

  • Rigorous governance across all delivery execution activities to safeguarding success.

  • Provided regular quality assurance reviews to our clients to maintain transparency and delivery confidence.

Technologies

  • ESX

  • Microsoft Azure.

  • AD / IDAMS

  • Encrypted VPN.

  • Third-party mass migration tools.

  • Data centre and cloud firewall configuration.

  • Design, implementation and configuration of residual services for environment security and management.

  • Database management, conversion and optimisation.​

  • SMTP management, conversion and optimisation.​

  • Development skills including web technologies, .NET, C++, python and apache skills.

  • DevOps CI/CD pipelines and code development for repeatable deployment and testing..

  • Containers, Kubernetes and Docker.

Benefits

  • Exited third-party hosted data centres without having to extend expensive contracts.

  • ​Offer a more robust, stable environment improving productivity and heightening the user experience, therefore their perception of the service.​

  • Take advantage of fit for purpose technologies updated to vender support levels.

  • Access to dedicated hybrid-cloud and on-premise hosting capabilities.

  • Realised operational and security efficiencies, significantly reducing technical debt and the risk profile.

  • Decreased technical skillsets and knowledge requirements by simplifying the estate, therefore the number of resources required to manage the estate.

  • Significantly reduce operational support costs..

  • Allow efficient connectivity to workloads hosted in multiple Azure subscriptions.

Outcome

The programme of works was achieved on-time and approximately 5% under the £4MIL budget. Once workloads had been on boarded into Azure, other workstreams of Continuous Service Improvement (CSI) activities were provisioned to enhance the technical estate further..
