Abstract

Cloud based operation model has become a new standard in ERP system implementation. This has brought a new software abstraction layer over the already existing datacentre model, which covered all the middleware, operating system and database level architecture elements. This new abstraction layer covers the complexity of the middleware and below layers, making it possible for the owners to deal with only implementing the core business logic. There is always a risk that more resources are allocated to the infrastructure side, using this model resources can be reallocated back to the business side. Overall this could lead to longer software lifecycle, because the core logic is separated from the rapidly changing implementation layer. The standard release management, which covered the way from pre alpha state to the gold release, was substituted in this model with a continuous release process. This leads to the possibility of using the latest version of the software always in the Software as a Service operating model. The code reusability (and refactoring) is also modified, having an abstraction layer between the platform independent model and the platform specific model. The transformation layer between these two has to be able to ensure the long term reliability of the software product. Having a proper transformation layer keeps the roles separated, the end user do not have to build up an IT support background, because this layer hides the infrastructure questions. This paper focuses on the change management procedures when change the operation environment from the standard datacentre solution to the cloud based SaaS model. This paper describes the different directions which can be used for an ERP environment offered by cloud technology, and focuses on the diverse change management procedures on switching the operation environment from the standard on premise datacenter solution to the cloud based SaaS model.
