Cloud computing technology architecture is divided into four layers: physical resource layer, resource pool layer, management middleware layer and SOA construction layer.

Next, Yunrong Technology will give you a careful analysis: the physical resource layer includes computers, storage, network facilities, databases and software. The resource pool layer refers to transforming a large number of resources of the same type into isomorphic or nearly isomorphic resource pools, such as computing resource pools, data resource pools, etc. The construction of resource pool is more about the integration and management of physical resources, such as how to install 2000 servers in the standard container space, solve the problem of heat dissipation and replacement of failed nodes, and reduce energy consumption.

Management middleware is responsible for managing cloud computing resources and scheduling multiple application tasks so that resources can efficiently and securely provide services for applications. The SOA build layer encapsulates cloud computing functionality into standard Web services and integrates it into SOA architecture for management and consumption, including service registration, lookup, access, and build of service workflows.

The management middleware and resource pool layers are the most critical parts of cloud computing technology, and the SOA build layer functions more dependent on external facilities. Compute management middleware is responsible for resource management, task management, user management and security management. Resource management is responsible for balancing the use of cloud resource nodes, detecting node failures and trying to recover or shield them, and monitoring the use of resources statistics;

Task management is responsible for executing tasks submitted by users or applications, including completing the deployment and management of user task images, task scheduling, task execution, task life cycle management, etc. User management is an essential link to realize cloud computing business model, including providing user interaction interfaces, managing and identifying user identities, creating execution environments for user programs, and billing user usage. Security management ensures the overall security of cloud computing facilities, including identity authentication, access authorization, comprehensive protection and security audit.
