Cloud computing has been developing for ten years. Today's cloud computing has undergone tremendous changes from technology types and functional products to industries and markets. Many enthusiasts' cognition and demand for cloud computing have also developed from the shallow concept of that year to the stage of eager for in-depth exploration.

Because fans have different personal abilities, others have different technical levels.

Here are some suggestions for beginners and cloud computing engineers.

If you have never worked in cloud computing and need to learn cloud computing, you must have knowledge of operating system, network and application services. Many vendors in the market have implemented cloud computing. Microsoft, IBM, Google, VMWARE and Huawei in the business camp all have very mature products. If you have enough funds, you will get very professional technical support and services when you buy any cloud product. (Just kidding, you can't usually afford it. If you are just an ordinary enthusiast, I suggest choosing KVM, XEN, OPENSTACK, DOCKER and other technologies in the open source camp. Because of ITs open source (free) characteristics, it has been widely welcomed by major IT Internet companies and enthusiasts in recent years.

To learn the cloud computing technology of the open source camp, we should learn from the management and use of Linux system (about 20 days) and a small amount of computer network communication technology (about 5 days), so as to lay the foundation for the virtual network technology in the cloud. Later, you should have a certain understanding of SHELL development and database system (10 days or so). At this time, it is possible to conduct a comprehensive study on the core technologies of cloud computing. Such as KVM, OPENSTACK, DOCKER container and other cloud technologies (20 days), master the architecture, functional roles and hierarchical classification of Iaas, Paas and Saas, and master the deployment and operation and maintenance capabilities of private clouds.

If you are a person who has already participated in related work, you know something about the above contents. My advice to you is that while mastering the above contents, you need to learn Python deeply, and you can comprehensively monitor and manage common servers such as cloud computing services, container services, cluster services and caches on the cloud platform, and carry out secondary development. This can be regarded as a comprehensive cloud computing expert. Because what you will face is not the independent server, computer room and equipment in the past. But tens of thousands of computers, distributed in cloud computing systems in different cities or countries, for all-round efficient and stable management.
