Research in cloud federation and the applicability of clouds 

Since mature cloud computing solutions are already existing and commercially available, our research efforts target specific open issues in the area of cloud federation and the applicability of clouds to the Telco domain.

While intra-cloud service offerings can be handled today, the migration of services between clouds is still an open issue today. This is due to the lack of widely accepted standards and agreed inter-cloud interfaces. Our research is centered on cloud federation and seamless integration of services between different cloud providers. This enables a number of scenarios for different sectors (e.g. Energy – “Follow the sun”, IT – “Shortest link to my virtual computer”, etc.)

In the Telco domain, cloud scenarios for fixed and mobile services offer a range of new business models and revenue streams. Due to reduced requirements for upfront investment, out- and In-sourcing of services offers new possibilities to SMEs and startups to get their business from the ground. The flexibility and elasticity of the cloud in combination with cloud-based Telco SDPs allow operators to quickly adapt to new situations and react to market demands rapidly. Smaller companies and individuals benefit from a low risk of acquiring (on demand) high end computing infrastructure and are relived at the same time from time and resource consuming tasks like maintenance, security updates, etc.

Also for smart cities and in the context of the currently ongoing Future Internet discussions, cloud scenarios are highly interesting for supporting future applications, e-government services and regional service markets. Many regional data and service providers like governmental authorities, insurance companies, power suppliers, etc. would benefit from integrated processes to share data and enable the composition of new services (e.g. the “house-moving application”).
