Today, I will talk to you about how to realize the use of Memcache version of cloud database. Many people may not know much about it. In order to let everyone know more, Xiaobian summarizes the following contents for everyone. I hope you can gain something according to this article.

Introduction:

Memcache is a memory-based caching service that supports high-speed access to massive amounts of small data. Cloud Database Memcache Edition can greatly relieve the pressure on backend storage and improve the responsiveness of websites or applications.

Memcache version of cloud database supports Key-Value data structure, and clients compatible with Memcached protocol can communicate with Memcache version of Alibaba cloud database.

Cloud Database Memcache Edition supports rapid deployment in an out-of-the-box manner. For dynamic Web and APP applications, the pressure on the database can be reduced through caching services, thereby improving the overall response speed of the website.

The same as the local self-built Memcached is that the Memcache version of the cloud database is also compatible with the Memcached protocol, compatible with the user environment, and can be used directly. The difference is that hardware and data are deployed in the cloud, with perfect infrastructure, network security and system maintenance services.

Architecture:

Memcache version of cloud database adopts cluster version architecture. Memcache version of cloud database has built-in data fragmentation and reading algorithms, and the overall process is transparent to users, eliminating user development and O & M troubles. Each fragmentation node adopts an active/standby architecture to ensure high service availability.

Memcache version of cloud database consists of three components: Proxy server (service proxy), fragmentation server and configuration server.

Proxy server

Single-node configuration, cluster version structure will be composed of multiple proxies, the system will automatically implement Load Balancer and failover.

fragmentation server

Each shard server is a dual-replica high availability architecture. After a primary node fails, the system automatically switches between primary and standby to ensure high availability of services.

configuration server

It is used to store cluster configuration information and partition policies. Currently, it adopts dual-copy high availability architecture to ensure high availability.

precautions

The number and configuration of the three components are fixed by the system when purchasing the corresponding specifications of the cluster version, and the user cannot choose flexibly for the time being.

Memcache cluster uniformly exposes an access domain name, and users access this domain name for normal Memcache access and data operations. Proxy server, fragmentation server and configuration server do not provide domain name access, and users cannot directly connect to access it for operations.

After reading the above, do you have any further understanding of how to implement the use of Memcache version of cloud database? If you still want to know more knowledge or related content, please pay attention to the industry information channel, thank you for your support.
