Application modernization services address the migration of legacy to new applications or platforms, including the integration of new functionality to provide the latest functions to the business. Modernization options include re-platforming, re-hosting, recoding, rearchitecting, re-engineering, interoperability, replacement and retirement, as well as changes to the application architecture to clarify which option should be selected.

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 Software developed on out-of-date platforms using older programming tools can be inflexible and difficult to change. But tools and technologies are emerging that help IT leaders, to modernise existing applications and maintain their investment in systems that can still be critical to the business. In DwellTec, 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.
