Poskytování ICT služeb v cloudu

This thesis focuses on the ubiquitous cloud computing trend and particularly Software as a Service. The main goal is to specify all pros and cons of this concept for its customers and also cloud providers. The global perspective is then specified to Software as a Service and deployment of SaaS ERP products. The next goal is to define an appropriate method to analyze a company's needs prior to switching to the cloud. Furthermore, recommendations as to whether the cloud is better than an on-premise version should result from the previous analysis. Another aim is to form a process for successful switch to the cloud and ensure all important aspects of using cloud services are covered. Theoretical findings and recommendations are used in a practical example of SaaS ERP deployment. To reach all goals, a theoretical analysis of all available monograph and electronic sources, covering cloud computing and consultations with experts from the company; Algotech BSC, were used. The main added value is in the dual point of view on the topic, from customer's and provider's viewpoints with a more detailed focus on ERP. The author suggests the right procedure for switching to the cloud, guidance with calculating ROI, TCO and preparing all necessary contracts and agreements.
