Cloud computing emerges as one of the hottest topic in field of information technology. Cloud computing is based on several other computing research areas such as HPC, virtualization, utility computing and grid computing. The ready availability of cloud storage and compute services provides a potentially attractive option for curation and preservation of research information. In contrast to deploying infrastructure within an organisation, which normally requires long lead times and upfront capital investment, cloud infrastructure is available on demand and is highly scalable. However, use of commercial cloud services in particular raises issues of governance, cost-effectiveness, trust and quality of service. In order to make clear of Cloud Computing, this report emphasize the Cloud computing models, types of cloud computing, benefits of cloud computing, milestone in development of cloud computing, some cloud computing using organization and future development areas of cloud computing.
1. Cloud Computing An Overview
The term "cloud" is analogical to "Internet". The term "Cloud Computing" is based on cloud drawings used in the past to represent telephone networks and later to depict Internet in. Cloud computing is TCP/IP based high development and integrations of computer technologies such as fast micro-processor, huge memory, high-speed network and reliable system architecture. Without the standard inter-connect protocols and mature of assembling data centre technologies, cloud computing would not become reality too.
Cloud computing is a computing paradigm, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. With the advent of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly.
Cloud computing is a practical approach to experience direct cost benefits and it has the...
