Cloud migration

Abstract

Migrating on-premises applications to cloud environment has become a popular task for organizations. In this thesis, cloud migration is defined to be an action where one or more parts of an application are migrated to a cloud platform. Multiple motivations are mentioned for such migration like reducing costs, flexibility, and scalability of the application. This thesis also goes through different strategies for cloud migration. After that, a literature-based, generalized migration process for cloud migration was created. This created migration process was then validated against case process.

Phases in the case process were investigated through interviews. Interviews were done in two parts. First, all interviewees were interviewed one at a time. From these interviews, a draft of the case process was done. This draft was then validated and supplemented with a group interview.

After creating both processes, they were compared. It was found that the literature-based process had a lot of similarities with the case process. Also, it was found that the case process had a few tasks that were not mentioned in the literature-based process. These tasks were discussing future of the application, estimating workload and project end date, defining migration scope, and familiarizing customers with application. These can be said to be important tasks, and they should have been in the literature-based process too.
