Cloud computing provides computing power, software, data, and storage services without end users being aware of the source or configuration of the service. Cloud Computing enables IT departments to offer IT as a Service to their business and can benefit from the following:
- Agility: Re-provision infrastructure resources with ease, whilst minimising the impact to the end user.
- Scalability and Elasticity: Clouds can adapt, automatically to accommodate extra computing requirements.
- TCO & ROI: Reduce CapEx and OpEx allowing the IT department to focus their time more efficiently.
- End Point Independence: Most end users are already familiar with using cloud based applications (e.g. Web Mail) without the issues inherent in the use of end point devices.
- Reliability: A correctly configured Cloud offering would distribute the computing power across multiple Data Centers and sites to ensure business continuity and disaster recovery is maintained.
- Improved Security: End point devices security vulnerabilities are reduced through integrating multiple technologies, e.g. Cloud Computing with Desktop Virtualisation.
- Maintenance: Application maintenance is minimised as end points no longer require software updates and patching. Data center maintenance can be performed during business critical times, without affecting the running of the ITaaS.
Cloud Computing is the delivery of computing resources as a service rather than a product, whereby shared resources, software and information are provided to end points and other devices as a utility over the LAN or WAN. This is commonly referred to as IT as a Service (ITaaS).
