In the previous articles, the high-availability scheme for MySQL databases, master-slave replication, latency generation of master-slave replication, latency Detection and latency solutions (not fundamentally addressed), this master-slave replication scheme guarantees data redundancy while simultaneously reading and writing to share system pressure but is not a highly available solution. Because the master
Our business systems, whether internal enterprise systems or Internet application systems, require scalable and highly available systems. Scalability and high availability are not isolated. Only by combining them can we achieve the desired results.
Scalability is an optional attribute of a system, network, or process. It expresses the meaning that it can handle increasing work in an elegant way, or expand i

Detailed analysis of high-availability Redis service architecture construction
Memory-based Redis should be the most commonly used key-value database in various web development businesses. We often use it to store user login states (Session storage) in the business ), it accelerates the query of some hot data (which is faster than mysql) and implements simple message queues (LPUSH and BRPOP) and subscriptio

I. Common usage
Several common usage methods of redis include:
Redis single copy;
Redis multi-copy (Master/Slave );
Redis sentinel (Sentinel );
Redis cluster;
Self-developed redis.
Ii. Advantages and disadvantages of various usage methods
1. redis single copy
Apsaradb for redis uses a single redis node deployment architecture. It does not have slave nodes to synchronize data in real time and does not provide data persistence and backup policies. This architecture is suitable for pure cach

Highly available clustersI. What is a highly available clusterA highly available cluster is when one node or server fails, another node automatically and immediately provides services, and the resources on the failed node are transferred to another node, so that the other node has resources that can provide services to the outside. When a highly available cluster is used for a single node failure, the ability to automatically switch resources and services can ensure that the service remains onli
