j2ee|web| Architecture 1. Schema overview
The Java EE system includes such technologies as the Java-based Server Pages (JSP), the Java SERVLET, the Enterprise Bean,web service, and so on. The advent of these technologies provides a very competitive alternative to the development of Web applications in the E-business e
URLs. Separate the timed JS files to different servers, limiting the total number of requests each application server accepts, and discarding them.
Failure cases: Write log failure, high concurrent Access database failure, high concurrency lock failure, cache-triggered failure, application-initiated asynchronous failure, large file read/write exclusive disk failure, misuse of production environment failure, non-canonical process-induced failure (through caching), programming habits
thorough understanding of the whole, suggest everything from the command to the hand.
Specific reference: "Servlet and JSP core programming." 3. The Framework
The number of frameworks used for Java web development is downright outrageous, and the problems that occur as a result of a version update are endless. However, this is also the result of the evolution of Web technology, either choose to accept, or

The evolution of the Web site architecture
These three chapters highlight the high availability, scalability, and scalability of the site architecture.The 5th chapter mainly describes the high availability of the website architecture. It is almost impossible to ensure that a site is always fully available. The industry uses a number of 9来 to measure site availability, using failure points to assess site availability. Usability indicators are important indicators of site

Recently, the "large Web site Technology architecture" has been looked at again. In the middle of reading a "computer operating system" textbook, feel the technical structure of large sites have a deeper understanding. Take some notes on the understanding of these two booksThe traditional OS (Operator System) has four basic functions:

At this time, this Web report tool works in a way similar to products such as crystal report, it has the same advantages and disadvantages as an independent server (the independent server here refers to the logic, and can still be physically installed together with other servers ). For Java applications, the report software can be embedded into the J2EE application archite

scenarios are not very consistent. 2. What basic services do the backend need to do? Each request from Nodejs has a Basic Authentication header, and the server side must complete the user's login in the perimeter of the filter (each request requires a login) to control access to the resource. 3, why do you have to use Nodejs? I'm only interested in one feature, which is to seamlessly run the same code in both the browser and the server. The resulting results can be described like this: Imagine
