Redis High-availability architecture best Practices First, preface May 13, 2017, the application performance Management auditorium Guangzhou station successfully ended, among them from 37 Mutual entertainment DBA Wen in the venue and you have a wonderful Redis technology sharing. Redis is an open source API that is written in ANSI C, supports the web, can be persisted in memory, key-value databases, and provides multiple languages. Today, Internet

Tags: automatic target master-slave synchronization. com Run highlight keepalive high-availability TOC We usually say that the dual-machine hot standby means that two machines are running, but not both machines are at the same time providing services. When one of the service providers fails, the other one will automatically take over and provide the service immediately, and the switch time is very short. before combing the MySQL master-slave synchroni

Label:MMM (master-master Replication Manager for MySQL) MySQL Master Replication Manager provides a scalable suite of scripts for monitoring, failover, and management of MySQL master replication configuration. In the MMM high-availability solution, the typical application is a dual-master multi-Slave architecture, through the MySQL replication technology can realize two server mutual primary from, and at any time only one node can write, avoid multi-p

This set of solutions is also one of the solutions tested some time ago. This solution is relatively easy to deploy and maintain. In simple terms, keepalived is a mechanism specifically designed to provide high-availability features for lvs. It can realize that when there are two master-slave lvs and the master lvs is damaged, transfer the IP address and lvs to the backup lvs. Its high availability This set

Recently I am reading nosql. A major advantage of nosql over relational databases is high availability. Therefore, some questions are raised: Why does nosql achieve high availability while relational databases suffer from criticism in this regard? Relational Database Service Oracle and sqlserver are both distributed databases. Definition of distributed databases in wiki: Http://en.wikipedia.org

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

In the previous article, we realized the high availability of Exchange CAS servers, and today we look at the high availability of mailbox server MBX.Mailbox servers are used to store all users ' mailboxes, no doubt about the importance! The previous version of EXCHANGE2007 uses disaster-tolerant technologies such as LCR,CCR, while the more stable and up-to-date DAG technology is used in Exchange2010.What is

The highly available architecture of the database is a relatively unfamiliar area for those of us who are developers of the application side, is built on the basis of a specific database product environment, need to be like DBA so the database products have enough knowledge to be involved, although not in depth, but can through some classic highly available architecture to learn the idea. As far as I know, there are the following: MySQL Replication MySQL Cluster Oracle RAC IBM HACMP Oracle

High-availability clusters have a variety of solutions, such as the Keepalived program, and many more ways to implement a highly available cluster in the AIS family, the earlier Heartbeat,openais only as a reference model, and then the Cman that Red Hat developed on openais basis,There is also openais reference, the implementation of the independent Corosync of the project can be used for high-availability

Brief introduction Pureapplication System provides a flexible platform to run the various application workloads in the cloud infrastructure. This design is designed to enable applications running on the rack to achieve high levels of availability to help eliminate single points of failure. Enterprises that pursue the highest level of flexibility must consider how to run their workloads across multiple systems and geographically dispersed data center

The memory-based Redis should be the most commonly used Key-value database in various web development businesses, and we often use it to store user login states (session storage) to speed up some of the hot data queries (compared to MySQL, which has an order of magnitude improvement), Do simple Message Queuing (Lpush and Brpop), subscription Publishing (PUB/SUB) systems, and so on. Larger-scale internet companies typically have dedicated teams that provide Redis storage as a basic service to ind
