Essential guide to application modernisation

We look at the latest trends and technologies in application modernisation


Legacy applications can often be a major hindrance for organisations undergoing a digital transformation. Software developed on out-of-date platforms using older programming tools can be inflexible and difficult to change.

In this guide, we look at the latest trends in application modernisation and analyse trends such as DevOps, microservices, platform as a service (PaaS) and more, to  understand the essential role they play in today's software development best practice.
