Course Introduction：As modern applications become more complex, application downtime due to single points of failure is increasing. To solve this problem, failover mechanisms are increasingly used. This mechanism helps applications achieve high availability and seamless scalability. This article will introduce how to use Golang to build a highly available failover architecture. First, we need to understand the basic concepts of failover. Failover refers to the process of automatically switching its service island to a backup node or server when the primary node or server fails. This process ensures that even a main section

Course Introduction：Redis is an open source in-memory database that supports a variety of data structures, including strings, hashes, lists, sets, ordered sets, etc., and can be widely used in scenarios such as data caching, message queues, and real-time statistical analysis. When using Redis, since its data is stored in memory, once a failure occurs, the data will be lost, so failover is very important. This article will introduce the failover mechanism of Redis in PHP applications and its implementation. 1. Principle of Redis failover Redis failover master

Course Introduction：PHP and SOAP: How to handle failover and fault tolerance Introduction: When developing web applications, using the SOAP protocol to make remote procedure calls is one of the common ways. However, in actual applications, failures may occur due to network, server and other reasons, causing SOAP calls to fail. In order to improve the stability and reliability of the application, we need to implement failover and fault tolerance mechanisms. This article will explain how to handle failover and fault tolerance of SOAP calls in PHP. Failover: When a SOAP call fails

Course Introduction：What is Sentinel? Sentinel is a high-availability solution for redis. The master-slave replication we talked about earlier is the basis of high availability. However, pure master-slave replication requires manual intervention to complete failover. Sentinel can solve this problem. In the case of master-slave replication, when the master node fails, Sentinel can automatically detect the failure and complete the failover to achieve true redis high availability. In the Sentinel cluster, Sentinel will monitor the status of all redis servers and other sentinel nodes, detect failures in time and complete transfer, thereby ensuring the high availability of redis. Sentinel Cluster Construction Sentinel is essentially a redis service, but it provides different functions than ordinary redis services.

Course Introduction：How to implement load balancing and failover in Java In modern distributed systems, load balancing and failover are very important concepts. Load balancing can ensure that system resources are maximized, and failover can ensure that the system can still run normally when a failure occurs. This article will introduce how to implement load balancing and failover in Java and provide specific code examples. 1. Load balancing Load balancing refers to distributing requests to different servers to maintain balanced utilization of server resources. Implement load balancing in Java
