Data On-Boarding in Federated Storage Clouds

One of the main obstacles hindering wider adoption of storage cloud services is vendor lock-in, a situation in which large amounts of data that are placed in one storage system can not be migrated to another vendor, e.g., due to time and cost considerations. To prevent this situation we present an advanced on-boarding federation mechanism, enabling a cloud to add a special federation layer to efficiently import data from other storage clouds. This is achieved without being dependent on any special function from the other clouds. We design a generic, modular on-boarding architecture and demonstrate its implementation as part of a VISION Cloud, which is a large scale storage cloud designed for content-centric data. Our system is capable of integrating storage data from various clouds, providing a common global view of storage data. The users can access the data through the new cloud provider immediately after the setup, maintaining the normal operation of applications, so that they do not need to wait for the completion of the data migration process. Finally, we analyze the payment models of existing storage clouds, showing that transferring the data via on-boarding federation with a direct link between clouds can lead to significant time and cost savings.

Platforms for Smart Cities – connecting humans, infrastructure and industrial IT

Todays platforms have come a long way from being focused on technical aspects - improving the lives of engineers and developers - to powerful, socio-economic platforms affecting the daily lives of millions of users. These socio-economic platforms enable a new class of applications and services to emerge at an unprecedented speed, quality and cost. Cities and Urban Areas can increase their pace of innovation, while effort for planning and implementation can be reduced from timespans of years or even a decade to months. In this paper, we will show examples of such platforms and how they impact the communities they are implemented in.

Towards Cost Aspects in Cloud Architectures

One of the important aspects of Cloud computing is certainly the pay-per-use model; users have to pay only for those resources they are actively using, on a timely basis. This model paired with principally infinite resources promises to run applications at lower costs, arguably.
