1 Introduction
In the era of cloud computing, container technology provides a new way for application deployment. Container technology solves the problems of resource isolation, low resource utilization, and complex deployment that exist in traditional virtual machine technology. After the container is deployed, it has good isolation, which can effectively avoid problems caused by resource competition or failure. With the widespread application of container technology, container cluster management and scheduling systems have gradually become a key technology to improve cloud platform efficiency, reduce costs, and improve resource utilization. Therefore, establishing a robust and efficient container cluster management and scheduling system is an important direction for the development of container technology. Container cluster management and scheduling system design is a complex project that involves many technical fields, including computer networks, distributed storage, databases, scheduling algorithms, fault tolerance mechanisms, security mechanisms, logging, etc. This article will start from the three perspectives of cloud computing, distributed systems and container technology, sort out the general process and process of applying container cluster management and scheduling system, and give a complete architectural design plan for readers' reference.
2. Background introduction
2.1 Cloud computing
Cloud Computing is an emerging concept, and its demand for IT services has given rise to the rise of the Internet. Cloud computing allows users to access a variety of applications through the computing resources of networks and servers, and obtain the required services by purchasing computing resources and storage space. Cloud computing provides a wide variety of services that change frequently, such as databases, storage, analytics, big data processing, machine learning, artificial intelligence, financial technology, etc. Cloud computing separates IT services from infrastructure operations, allowing service providers and customers to expand without interfering with each other and respond quickly to user needs. Due to the huge dividends brought by this service model, many companies are committed to transforming into the cloud computing market.
2.2 Distributed system
Distributed System (Distributed System) is a computer system that distributes large-scale computer systems to different nodes according to functions, and communicates and works collaboratively with each other through the network. Today's distributed systems include large-scale cluster systems, cloud computing platforms, massive data center networks and Internet of Things systems. Characteristics of distributed systems include massive data storage
