1. How to put cloud computing into practice

We talked about the concept of cloud computing in the previous section, so let's think about how cloud computing is implemented in reality?

Now in the practice of cloud computing, an effective system has been formed. A company’s traditional business, such as database, computing engine, front-end, etc., needs to go to the cloud. First, we need an IaaS. This IaaS can rent a framework already built by a large company, or build an IaaS by ourselves. Today, there are three ways to build an IaaS by yourself. There are three mainstream tools: OpenStack, VmWare and RedHat . These three methods have their own advantages and are competing fiercely. We can wait and see who can win the last laugh in the competition.
