Architectural design is the product of people’s subjective mapping of elements within a structure and the relationships between elements. Architecture design is a series of related abstract patterns used to guide the design of various aspects of large software systems. The architect’s job responsibility is to transform the customer’s needs into a standardized development plan and text during the development of a software project, and to formulate the overall structure of the project, and guide the entire development team to complete the plan. Architecture design is the early stage of the software design process, which connects the requirements analysis and the design process. The main task of an architect is not to write specific software programs, but to engage in higher-level development and architecture work. He must have a good understanding of development technology, and he needs to have good organizational and management skills.
LVS Load balancing scheduling algorithm

The scheduler distributes external requests to the real servers of the cluster in turn through the “round-robin” scheduling algorithm. It treats each server equally, regardless of the server The actual number of connections and system load.
