Cloud migration of standard software

The software solution is made up of two components. The main application runs on a number of VMs in an 'Infrastructure as a Service' environment in Azure. An additional middleware component is responsible for the data transfer between the application and the other internal and external systems. The middleware is a 'Platform as a Service' solution and makes use of a variety of Azure services, including messaging via an Azure Service Bus. An important part of the project is the appraisal and, where necessary, upgrade of the application architecture in agreement with the software vendor. PTA also has complete responsibility for the test management, including the test concept, as well as supervising the technical and business/key user tests.
