designing a distributed web system architecture. However, they may also conflict with each other. for example, to achieve a certain goal, they sacrifice another one. A typical example: when focusing on system capacity, the cost of simply adding more machines (scalability) is (increased) manageability (you need to maintain more servers) and cost (more server prices ). When designing any
Lists the concepts involved in large-scale website architectures, with a simple explanationObjective
This article is the "Large Web site architecture design" (HAE) a book, similar to the text version of the "Mind map"
The full text focuses on the "performance, availability, scalability, scalability, security" of the Five Elements
Performance, availability, scalability these elements are bas
By reading this book we can more clearly set up a large-scale website of the technical development process, analysis of large-scale Web site technology architecture model, in-depth talk about the core principles of large-scale Internet architecture, and through a number of typical technical cases to tell a large web si
Chatting with friends, I found a lot of people are very interested in large-scale web system architecture, I am also very interested, often in the home of 2 laptops and 1 servers in the LAN environment to do some experiments. I entered the IT industry time, about 97, 98, then the PC client software is the most popular, do software development is a very decent and very like work. I started from the VC1.5 on

Step 8 of Architecture Evolution: add more webservers
After database and table sharding, the pressure on the database has been reduced to a relatively low level. Then, I began to live a happy life of daily traffic surge. suddenly one day, we found that the system access started to slow down again. At this time, we first checked the database and the
The web is a typical distributed application architectureArchitecture of distributed computing: currently mature technologies include Java EE, CORBA and. NET (DCOM)In the 1992 of popular C/s, the OMG organization proposed CORBA, which greatly improved the development efficiency of distributed application software.Another Distributed system development tool at the time was Microsoft's DCOM. In order for Microsoft to enable the functionality of various

This allows a process to process multiple requests, and each request has its own state, and this request can also send me a notification.
