Integration has always been an important and tricky task for IT-businesses. There are several products available for solving integration issues, one of them is the long developed platform BizTalk from Microsoft. As cloud computing has grown in recent years, Microsoft has been putting more focus towards the cloud. With their cloud, named Azure, expanding a new integration platform have been released, the iPaaS (integration Platform as a Service) Logic Apps. This report aims to evaluate the integration platforms Logic Apps and BizTalk with the purpose of finding out if the new Logic Apps can replace the long developed BizTalk. The evaluation is performed by implementing an application in both platforms, then evaluating selected parameters by giving each a score to concretize our assessment on quantify whether Logic Apps can replace BizTalk.

Cloud computing is still in an early stage of development and Microsoft is now investing considerable amount of resources in the cloud. Microsoft Azure is a cloud platform developed by Microsoft and it is continuously evolving, new features are constantly being added and old features are being updated. Integration Software, which is a company that focuses on products for system integration strongly believes that cloud­-based solutions will have a significant impact on their future. This is why selling and developing solutions and services for the cloud are strategically important for them. The objective of this dissertation is to investigate Microsoft Azure in general and Azure Marketplace in particular. This investigation consisted of an implementation of a Microsoft Azure application and integrating this application with Azure Marketplace and evaluating the expenses for running the application. The purpose for this project is to gain practical experience and to work with new techniques and help Integration Software better understand Azure Marketplace. The application is a Log Agent which fetches data from an external source and resends the data to an external party (Integration Manager). Our first intention was to package and deploy the application to a newly updated Azure Marketplace. The new Azure Marketplace was never released during this dissertation so we decided to deploy the application to the existing version of Azure Marketplace. This was however not fully successful. We encountered some problems in successfully deploying the application to Azure Marketplace. The evaluations for the cost of running an Azure application were not carried out due to lack of time.
