Before discussing the nlayerapp project, let's first learn (or repeat) the hierarchical/multi-layer architecture and application system design principles. Many of my friends will think that these are old-fashioned content. As long as they are software practitioners, they will be very familiar with this content. But is that true? I will sort out this part here. On the one hand, it will lay the foundation for

When we first started to learn about architecture, we first thought of the concept of hierarchy. What is a layer-3 architecture? It includes the presentation layer, business layer, and data access layer. For a novice, the three-layer architecture in the abstract sense is logically divided into three layers.
This is the most basic three-tier

uses the Master/slave architecture. An HDFS cluster consists of a namenode and a certain number of datanodes. Namenode is a central server that manages the file system's namespace (namespace) and client access to files. The Datanode in a cluster is typically a node that is responsible for managing the storage on the node it resides on. HDFs exposes the namespace of the file system, allowing users to store

Background: Some Web sites need to meet customer requirements of high concurrent requests, large data access, and so on, these scenarios need to conduct a holistic architecture analysis of the site, and then determine the system architecture that meets the requirements, including server clusters, load balancer selection, database cluster
