Legacy application transformation

We’ll support you in transforming your legacy technology and applications so you can provide systems and services that meet your users’ needs.

How we can help

The legacy technology challenge

Legacy technology means technology that is out of date or obsolete. This can refer to systems, technologies, software or hardware. Often this technology supports extremely important functions and services within an organisation.

Legacy applications make it difficult to modernise in the public sector, because when systems are out of date, organisations struggle to deliver great services.

Sometimes, teams can update the customer interfaces, but the back-end systems are harder to change.

They are also not able to respond to the needs of growing numbers of service users across the UK.  Moving systems to the cloud is a critical step in modernisation.  But this can be difficult because of:

  • complex, inflexible platforms 
  • long legacy contracts
  • locked-in data

Legacy systems often need manual, tedious processes to minimise risk and maintain compliance. This can hold organisations back.  As a result, software releases become infrequent and time-consuming.

How we work

We support public sector organisations to move to the cloud, building new skills and confidence into every step of the journey.

We will work with you to transform your legacy applications and systems into cloud-native applications. We can help you to:

  • reduce time, cost and operational inefficiencies
  • maintain security
  • build in resilience and compliance

We’ll work alongside you to plan and implement your modernisation process. Our approach involves measured, incremental steps. We will support you to increase:

  • the cloud maturity of your platforms and systems
  • the automation in your software development lifecycle (SDLC) 
  • the knowledge and ways of working within your teams

The five phases of legacy application transformation

Made Tech uses 5 phases to transform legacy applications to cloud-native.

We start by rapidly mapping out your applications and systems. We identify the technologies and dependencies your applications are using. This helps us to draw a picture of how your technology works and to recognise areas of complexity. We can then identify where we can make quick wins.

Next, we analyse your current technical systems, scoring them against 36 maturity factors. We use quadrant mapping to measure the business value of modernising them and the technical effort needed. This helps us identify and agree on which legacy applications we can move forward with.

In the next phase, we’ll move a set of legacy applications to a cloud platform. The process is called re-platforming, and it takes weeks, not months. Re-platformed apps often don’t yet meet all 36 maturity factors — that’s something we’ll do in step four.

The cloud maturity of re-platformed applications improves and larger, more complex apps are transformed. We’ll also focus on complex, non-functional requirements. These can include performance, security and compliance.

We will support and coach your teams to use the new cloud-native approach. They will become self-sufficient, and will be able to deliver software products using a cloud-native approach.

Authentication remains a pain point for millions of people when they try to use a digital service. But we can solve much of this with a simple change in mindset – accepting that it’s fine for someone to do something on someone else’s behalf.
