It provides DDoS attack identification and mitigation functions that can be used after opening packages and have been tested in practice. Such functions can be deployed quickly with few configurations and even in the process of attack occurrence. Pravail APS focuses on protecting the network boundary from threats to availability, especially providing protection against application layer DDoS attacks, and can meet the increasingly severe challenges faced by managers when they are in DDoS attacks. By using a series of countermeasures, Pravail APS detects and blocks DDoS attacks, especially in cloud environment.In the last article, we explained Redis' master-slave cluster mode in detail. In fact, the configuration of this cluster mode is very simple. It only needs to be configured on Slave's nodes. The configuration of Master's master node does not need to be changed. However, one thing is that the persistent configuration of Master and Slave nodes should be consistent as far as possible, otherwise there will be strange problems. Starting today, we will begin to talk about the second mode of Redis cluster mode. That is, the "Sentinel" mode, which was provided from version 2.6 of Redis, but the mode of this version was unstable at that time. The Sentinel mode did not stabilize until version 2.8 of Redis. In the production environment, if you want to use the Sentinel mode of Redis, you will try to use the version after version 2.8 of Redis. Whether it is master-slave mode or sentinel mode, both modes have a problem and cannot be expanded horizontally, and the high availability of these two modes will be limited by the memory of Master master node. Another point is that the configuration of Sentinel mode is not simple or even complicated, so neither mode is recommended in industrial scenes. If you want to use it, you must have solutions to related problems to avoid subsequent problems.当初一个是镇守关中的雍王，一个是雄踞淮南的九江王，而今全都是越王尹旭麾下的上将军。是啊。
