When you need to configure capacity with minimum friction, you should have Amazon EC2. This is because it works more or less like Amazon simple storage service (Amazon S3) does when it enables “compute” in cloud. Amazon EC2 simple interface provides you with total control of the computing resources you have thus allowing you get and configure capacity. Moreover, it minimizes the time you may require to get and boot new server and so you do that in minutes. This is quite convenient, since you will be able to scale capacity quickly, both up and down, when your requirements in computing change. By so doing, Amazon EC2 allows you to pay for capacity that you use. This changes your computing economics dramatically and enables you to enjoy the whole experience. Using Amazon EC2 is a good way of computing cheaply and can make you utilize your resources well while online.
