Cloud Computing

The book I read to research this post was Cloud Computing by The Chartered Institute for IT which is an excellent book which I bought from Kindle. This book is only 75 pages but it only cost £1.75 for the ebook so I think it's good value & it does contain quite a lot of information. Cloud Computing has been around in one form or another since the mid 90's. A lot of people worry about Cloud Computing especially the reliability & security issues but it's worth mentioning a lot of people including businesses use sites like GoogleMail for their email which is a form of Cloud Computing & a lot of the issues people worry about have been resolved. Obviously volatile information is best kept on a company server but every company has a lot of information that potentially can be kept on a cloud server. It represents a very exciting time for businesses when they haven't got to invest so much in computer hardware. Also a lot of company servers only run much of the time maybe at 5% capacity because they have to allow for spikes in demand, cloud servers aren't as susceptible to these spikes, so it's more efficient which is better for the environment. A lot of cloud service providers are installing things like solar panels & using renewable materials something which is bound to become more of an issue as time goes on. One thing which a lot of companies are using in connection with Cloud Computing is cryptography which can be used over the network, on the cloud server, in the application, or when being used by an end user.
