Solution Overview

This solution helps you set up high-availability RabbitMQ cluster on Huawei Cloud Elastic Cloud Servers (ECSs). RabbitMQ is open-source message-oriented middleware developed in Erlang to implement the Advanced Message Queuing Protocol (AMQP). It supports multiple programming languages.

Architecture

Architecture Description

This solution will:

1. Create three Linux ECSs, which will be deployed in different AZs to work as RabbitMQ nodes.

2. Create three elastic IP addresses (EIPs), which will be used for internal and external communication.

3. Create a security group to enhance ECS security and set security group rules to specify ports that allow access to the ECSs.
