Application Modernization

One of the simplest ways of modernising applications for the cloud is rehosting, also known as “lift and shift”. In this process we move your existing applications, in their entirety, from a legacy environment such as an on-premise server to a public cloud to improve accessibility and performance. This is the least resource-intensive method and allows us to migrate applications rapidly. However, it may not be the optimal choice for complex applications where high performance is required.

For many applications, in order to ensure optimal performance, we will need to modify or adapt the underlying code, to ensure it can take full advantage of the features available when running in a cloud environment. The re-platforming process does not involve a full rewrite of the application, but instead, we make functional changes, for example, modifying or restructuring the backend database to ensure it works efficiently on the target infrastructure.

For complex and business-critical applications the most effective modernisation approach is to restructure and rewrite legacy software to optimise it to run in a cloud environment. This approach is often used in order to break down large legacy applications and decouple functionality to achieve a microservices architecture, which maximises the benefits of cloud-native tools such as containers and container orchestration.

As part of the application modernisation process, we assess and document existing interdependencies as well as compatibility and integration requirements in the target cloud environment. We adapt or redevelop software integrations as necessary to ensure that your systems remain compatible and interoperable once the migration to the multicloud is complete.
