Cloud Migration
NHS
One key challenge of the NHS is to migrate all software and applications to new technology to simplify internal IT so that server, storage, and operating system software doesn't need to be installed locally. This would improve and be easily scalable for futureproofing. The solution for this would be to utilise a major Cloud computing provider such as Amazon Web Services.
General Practice Data Collector was an application originally built on a hardware server. Due to servers being considered legacy technology and having limitations such as memory and storage capacity, it was imperative that GPDC was migrated to AWS Cloud platform. GPDC was dependent on several other databases, applications and interfaces which meant that this wasn’t a simple “lift and shift”.
ThinkTribal provided a blended team of external consultants that worked with senior NHS resource to ensure all requirements were captured and prioritised prior to creating a full backlog. This included developers, data engineers and technical leads.
Our solution consisted of developing a minimal viable product that could be released in parallel to the legacy system. This could be tested by the agile team, and the live service team that administered the data collections, before switching off the server and switching on the new application in the Cloud.
ThinkTribal’s involvement supported NHS Digital’s roadmap to move all applications to AWS Cloud. This was delivered in under 6 months and resulted in just 4 hours of system downtime which was conducted outside of peak data collection hours.
ThinkTribal then seamlessly handed over GPDC to the live service data operations team who could continue administrating and maintaining the dataflows to ensure all supplier and customers could continue business as usual.
