power for uninterrupted power supply users, improving the reliability of the power grid. At the same time, due to the independence of the distributed power supply, it can be disconnected from the power grid, the distributed power supply is used to form an "island" for separate power supply. On the other hand, because each part of the power supply is relatively independent, redundancy technology or backup b

Recently, the company launched a nationwide Business System, which covers all business processes. Users include 32 subsidiaries nationwide, it can be said that it is a huge system that puts all the eggs in the same blue, how hard it is to go online, just to say that some problems after the launch bring me some inspiration for business system design.

Author: Wang, JoshI. Basic overview of Kafka1. What is Kafka?The definition of Kafka on the Kafka website is called: adistributed publish-subscribe messaging System. Publish-subscribe is the meaning of publishing and subscribing, so it is accurate to say that Kafka is a message subscription and release system. Initially, Kafka is actually a distributed message queue used by LinkedIn for log processing, and the log data of LinkedIn is large, but the re

If you want to develop a daily traffic millions, or even tens of millions of levels of access to the Internet platform, performance and security is the first factor to consider. Single from the performance, mainly from the following aspects of consideration:1) hardware and network equipment;2) distributed, clustered, read-write separation, CDN acceleration, etc.;3) use the good development framework to make full use of the caching mechanism;4)
coupling granularity lies in the application design, some application systems write code to initialize and inject some content into the memory, or inject it into a local file of the app as the File Cache; in this way, when the data changes, they first change the database, and then modify the memory or notify the memory to become invalid. Because the cluster uses heartbeat connection, the database remains c

Issues to consider
From the signal waveform,High-speed digital design needs to consider the vertical and horizontal aspects: the quality of each signal, the mutual timing between signals.
The quality of each signal mainly involves three aspects: signal integrity, power supply integrity, and crosstalk.
