Origins of the Cloud
It all started with huge ISP such as google and that´s where a new architecture was born. This became the new way to use distributed resources through the internet. Although similar to grid computing, cloud computing does not fail if one of its many pieces happen to fail.
Cloud computing is the result of the improved deficiencies of grid computing. When companies who wish to outsource their data center infrastructure can scale up(scalability) to their current needs and without investing in it. Customer actually don´t even care about how things work inside the cloud since he can access his data from anywhere.
Cloud computing is also environmentally friendly because there´s less hardware and less energy consumption.
