Towards Secure Migration to Cloud Environment

Abstract

As the amount of data trafic increases around the world, development of bigger and more effective systems is needed. Cloud services introduces the possibility of running systems in a scalable and exible environment. Instead of upgrading On-Premise systems to fit the new demands of data ow, migration of these systems and their corresponding services to the cloud is a good option to be considered. However, migrating systems to the cloud might introduce security questions and reservations, as the data isn't located and controlled On-Premise any more. This thesis aims to show that a system migrated to the cloud, is at least as secure as hosting it On-premise, when a first step towards a migration is performed. This step is implementing a hybrid cloud solution, based on Windows cloud service called Azure, where the type of the migrated system is of integration nature based on Microsoft's integration platform BizTalk. The cloud services are still rather new on the market, which in practice means that there still are room for development and standardizations for security aspects. If having no rush into the cloud environments, small steps towards a hybrid solution really seems like a good way to go, as this minimizes security implications. The results provided in this thesis, shows that a hybrid cloud solution is as least as secure as a traditional, On-Premise system.
