Preparation Before Ordering
Before you create a DMS RabbitMQ instance, you need to make some preparations.
First, you need to set up a virtual private cloud (VPC), which is an isolated network environment to host the RabbitMQ instance.
Next, you need to create a subnet, which is a subnet inside the VPC to separate different parts and regions.
Finally, you need to configure a security group to control inbound and outbound traffic rules to ensure the security of RabbitMQ instance.
Each DMS RabbitMQ instance is deployed in a specific VPC and associated with a specific subnet and security group. This allows you to configure and manage the network environment of your RabbitMQ instance on your own, and provides security protection policies. If you already have existing VPCs, subnets, and security groups, you can reuse them without having to additional creation. This saves time and resources, and also ensures consistency and reliability.
VPCs and Subnets
VPCs and subnets can be reused, or you can use different VPCs and subnets to configure RabbitMQ instance based on your actual needs. When creating a VPC and a subnet, keep in mind the following requirements:
l The VPC and the associated RabbitMQ should be located in the same region.
l If you have no special requirements, you can use the default configuration to create VPCs and subnets.
For operations about how to create a VPC and a subnet, refer to Virtual Private Cloud (VPC) - Creating a VPC and a Subnet, and Building a Private Network.
If you want to create and use a new subnet in an existing VPC, refer to Virtual Private Cloud (VPC) - Subnet Management - Creating a Subnet.
Security Group
Security groups can be reused, or you can use different security groups and configurations based on your actual needs.
For more operations about how to create a security group, refer to Virtual Private Cloud (VPC) - Creating a Security Group.
If you want to add rules to a security group, refer to Virtual Private Cloud (VPC) - Security Group - Adding a Security Group Rule.
ECS
To connect your client application to RabbitMQ to send and consume messages, purchase an ECS and ensure that the ECS is located in the same VPC as the RabbitMQ instance. For creation instructions, see Create ECS.
Other Tools
Download and install Eclipse 3.6.0 or later, or IntelliJ or JDK 1.8.111 or later.
Purchasing a Kafka Instance
(1) Log in to the management console.
(2) Go to the RabbitMQ console.
(3) In the upper-right corner of the management Console, click Region Name and select a region. Here, select the same region as your application services.
(4) Click Purchase Instance to jump to the purchase page.
(5) Select the instance specification
You can select general-purpose or computing-plus type. The details are shown below:
ECS Type | Number of Nodes | Instance Specifications | Storage I/O | Storage Space (GB) |
