Enterprises in the Clouds – Current Trends and Future Directions

Cloud Computing is an emerging area of research with many directions. Computational and data clouds are large-scale distributed systems used for serving demanding applications. Cloud computing is a concept that has emerged from grid computing; it provides users the ability to acquire computational resources on demand from its virtually infinite pool on a pay-as-you-go basis.

The cloud computing paradigm can offer various types of services, such as computational resources for high-performance computing (HPC) applications, web services, social networking, etc.

For many years now, the use of HPC has become important in the enterprise. Companies need to process large amounts of data and realise that they need HPC for success of their business. While large enterprises have budget for a HPC system, smaller companies usually do not have enough funds to deploy such solutions. However, they can extend their computing provision by consuming Cloud services. Therefore, software structures that best exploit clouds capabilities while providing enterprise applications compatibility should be examined.

In this talk we will present issues that must be addressed in order to make clouds viable for enterprise HPC, and will review research, based on existing or simulated cloud systems, that provide insight into problems solving. Advanced modeling and simulation techniques are a basic aspect of performance evaluation that is needed before the costly prototyping actions required for cloud systems.
