Cloud servers are an alternative to the traditional dedicated and virtual private servers as they are not confined to a single system or its resources. Cloud companies like AWS, Azure and Google provide numerous cloud based services for business of all kinds. The cloud servers are unique in a way that they are easily scalable and cost significantly less than the traditional dedicated and virtual private servers. Thus regardless of your size and traffic, you can use cloud servers to build and run any kind of application. You are only charged for the amount of resources you use and thus running your applications becomes much more efficient.
