An Early Performance Analysis of Cloud Computing Services for Scientific Computing
Scientific computing requires an ever-increasing number of resources to deliver results for growing problem sizes in a reasonable time frame. In the last decade, while the largest research projects were able to afford expensive supercomputers, other projects were forced to opt for cheaper resources such as commodity clusters and grids. Cloud computing proposes an alternative […]
The NIST Definition of Cloud Computing
Note 1: Cloud computing is still an evolving paradigm. Its definitions, use cases, underlying technologies, issues, risks, and benefits will be refined in a spirited debate by the public and private sectors. These definitions, attributes, and characteristics will evolve and change over time. Note 2: The cloud computing industry represents a large ecosystem of many […]
The Eucalyptus Open source Cloud computing System
Cloud computing systems fundamentally provide access to large pools of data and computational resources through a variety of interfaces similar in spirit to existing grid and HPC resource management and programming systems. These types of systems offer a new programming target for scalable application developers and have gained popularity over the past few years. However, […]
