1, three-tier architecture The three-tier architecture of the three-tier architecture (3-tier application) is to divide the entire business application into the presentation layer (UI), the Business Logic layer (BLL), the data Access Layer (DAL). The purpose of distinguishing hierarchy is to think of "high cohesion, low coupling". 1, the performance layer (UI): P

1, b/s structure: where B represents browser (browser), S represents server (server), S/b architecture is browser/server architecture. A simple schematic diagram of B/s architecture: In b/S architecture, HTTP protocol communication is used between the browser and the server. The advantages of B/s

multiple servers is formed by means of routing differentiation;Iv. Extensibility-A new business is on the line(1) Measurement criteria: Is it possible to achieve transparency without impact on existing products when new business is added (does it need to be modified to match existing business?) ）；(2) Main means:① Event-Driven architecture: Using message Queue implementation;② Distributed services: separating business and reusable services;V. Security

Design objectives: -(Hardware failure is normal, not accidental) automatic rapid detection to deal with hardware errors -Streaming Access data (data batch processing) -Transfer calculation is more cost-effective than moving the data itself (reducing data transfer) -Simple data consistency model (one write, multiple read file access model) -Heterogeneous Platform portability HDFS Architecture Adopt Master-slaver Mode: Namenode Central Server (Master)

MySQL master-slave replication principle and architecture, mysql master-slave architecture1 copy Overview The built-in replication function of Mysql is the basis for building large and high-performance applications. This distribution mechanism replicates data from a Mysql host to another Server Load balancer instance, and execute it again. During the replication process, one server acts as the master server, and one or more other servers act as slave

The so-called architecture, a popular saying is "the highest level of planning, difficult to change the decision", these plans and decisions laid the direction of the future development of things and the final blueprint.The software architecture is "an abstract description of the overall architecture and components of the software, which is used to guide the desi

in the Agile development , we did find a framework that would enable domain experts, architects, to work together to design an adaptable ROA architecture. But I think we should think of it from another angle. ...even domain experts and architects can work together in a team, but after all, domain experts and architects are people, not gods. So, in the end, how much of the future needs change can be predicted from the current version ? This is really
