Modernisation. Redefined.

We are passionately pragmatic, and will meet you where you are on your modernisation journey. Often our clients have deployed workloads in AWS, however they are not yet getting full value because they:

Learn more about the modernisation journey
  • Are spending too much
  • Have too much manual work / process inefficiency between systems
  • Have applications built on a legacy code base, including outdated design patterns and frameworks
  • Have not fully adopted a DevOps mindset and are not confident to release code
  • Have siloed data across multiple systems which is not yet providing the value it should

We strongly believe that modernisation across infrastructure, applications and data provides a clear pathway to ultimately getting AI done right, first time.

D55 Background

AWS excellence at our core

We specialise in complex application modernisation, not undifferentiated lift and shift. Examples of our common engagements include:

  • Application level development, we’re specialists in .Net and Java – and crucially how these frameworks best interact with AWS services such as Lambda, ECS and DynamoDB to build a truly modern architecture. Often this involves moving from traditional 3-tier configurations to a low cost, scalable serverless architecture using Node.js and Lambda.
  • Infrastructure optimisation, such as the move to a blisteringly fast and fully managed serverless Aurora database – and associated removal of expensive Microsoft or Oracle licensing costs.
  • Meaningfully improve data quality, introducing new event driven workflows using your business logic. We can perform complex systems integration, including provisioning data lakes to not just aggregate and query data in real time.

Our Advanced Partnership status with AWS and multiple service delivery specialisms validate D55’s profound technical expertise, experience and track record in delivering cutting edge solutions to our clients. Working with D55 and AWS is a true partnership. If you want us to manage it all, we will - but more commonly, we’ll work with your teams to upskill and enable them along the way.
