1 Introduction
Cloud computing (Cloud Computing) is a service platform built by a series of Internet technologies. By migrating applications, data, and services running on a central server or server cluster to an area closer to the user for deployment, the platform provides Computing resources, network bandwidth, storage space and other advantages can accelerate the operation of applications quickly and at low cost. The concept of cloud computing first originated from the Department of Information Industry of the US Department of Defense, which is defined as "the sharing of the ability of network providers, service providers, and users to access computing resources through the Internet." With the rapid development of the Internet and the development of cloud computing technology, more and more companies and organizations have begun to adopt cloud computing, such as Google, Amazon, Microsoft Azure, IBM, etc. As of 2019, the global public cloud market has exceeded US$120 billion, covering an area of 30,000 square kilometers. The private cloud is mainly used for the internal business of the enterprise, covering software and hardware resources such as data centers, servers, and network equipment. Hybrid cloud is a combination of public cloud and private cloud to provide the best value for different users.
"Cloud Computing Architecture Design and Application" is a comprehensive technical work on cloud computing, which aims to spread the concept, method, technology and application of cloud computing. The author deeply analyzes the definition, characteristics, classification, applications and solutions of cloud computing, and focuses on the design and implementation process of cloud computing architecture. This book not only provides a complete architecture design idea, but also supports detailed cases to help readers master the core knowledge of cloud computing.
2. Cloud Computing Concept Terminology
2.1 Cloud Computing Concept
Cloud computing is a new form of information technology, which refers to providing computing resources, network bandwidth, storage space and other advantages through the network to accelerate the operation of applications quickly and at low cost. Cloud computing covers three forms: public cloud, private cloud and hybrid cloud. Public cloud is a service form of cloud computing, which provides a series of computer hardware, software, network services and network infrastructure available to users, and allows third-party customers to rent. A private cloud is a computing service run within an enterprise, allowing users to independently manage their own hardware, software, network and data environments. hybrid cloud
