Redis Pub/Sub is an at-most-once messaging system that allows publishers to broadcast messages to one or more channels. Celery and script/web-application on separate machines. The redis-server package provides Redis itself, while the php5-redis package provides a PHP extension for PHP applications like WordPress to communicate with Redis. Internals: Learn details about how Redis is implemented under the hood. This microservices book is the best introduction to key Redis microservices terms and concepts. How does the communication between two different pods happen in Kubernetes? Redis Cluster also provides some degree of availability during partitions , that is in practical terms the ability to continue the operations when some nodes fail or are not able to communicate. Well, that's it for today! Celery worker will also communicate with, get the task from redis on this server and execute it. Both kind of sockets are materialized by file descriptors. Redis Protocol specification: if you're implementing a client, or out of curiosity, learn how to communicate with Redis at a low level. I am trying to write a module that communicates with redis. More precisely, Redis Pub/Sub is designed for real-time communication between instances where low latency is of the utmost importance, and as such doesn’t feature any form of persistence or acknowledgment. So far its doing following things. Redis can operate both as a NoSQL database store as well as a cache.

I hope these two "tricks" for using Redis to solve inter-service communication will be helpful to you. Redis can handle classical TCP sockets, but also stream oriented unix domain sockets. You need to consider how your data is managed, build interservice communication, and synchronize data across geographies and availability zones. Unix domain sockets can only support local inter-process communication.
