First of all, as a programmer, you must be proficient in using various frameworks and understand their actual installation and the principle of jvm virtual machine. Nanning Nanning Computer Training believes that knowing the jvm can enable you to write code with better performance.

Technical entry familiar with tcp protocol. In order to create a three-way handshake connection, the whole process of four handshakes is disconnected, and it is impossible to optimize the network application with high concurrency. Familiar with http protocol, especially http header, computer training thinks that there is no work for more than five years that can't understand the life cycle of session and cookie and their relationship.

Memcached, redis, a distributed caching technology, is necessary to improve system performance.

In short, Nanning Beida Jade Bird found that putting the contents of the hard disk into the memory can improve the speed, and by the way, there is an integrated hash of the algorithm.

Mysql is essential for database design ability. The most basic database tools are easy to use. Its basic parameters are optimized, the query log analysis is slow, and the master-slave replica configuration is at least a semi-mysqdba.

Other nosql databases such as mongodb.

To be an architect, you need to know more than just a lot of technology. These are the foundations and tools for solving problems. Without this knowledge, you can't think of a solution. Nanning Computer Learning thinks it is necessary to be an architect.
