Instance Introduction
You can subscribe to RabbitMQ instances with user-defined specifications and features, and deploy them in physically isolated areas. A RabbitMQ instance is exclusive to the tenant and can be customized with business-based specifications. On new resource pool nodes, rich options such as selecting host types and storage specifications are also supported for users.
Procedure
1. Click Activate Now on the Product Details page, or on the message management Console, create an instance and go to the page for ordering DMS RabbitMQ.
2. Create an instance and select the product specification.
(1) Specify an instance name. The name must be 4 to 64 characters in length and start with a letter. The name can only contain letters, numbers, hyphens (-), and underscores (_), and cannot contain other special characters.
(2) Select the engine type, the Native Cloud Engine is selected by default, with massive message accumulation capability, supporting more connections and queues, and high stability. You can also choose the RabbitMQ engine, which fully supports the open-source RabbitMQ ecosystem and has complete functions.
(3) Select a billing mode. There are two billing modes, namely yearly/monthly subscription and pay-as-you-go billing. See Billing Modes for details.
(4) The purchase duration varies based on the billing mode you have selected:
l The billing mode is a yearly and monthly subscription, with the option to purchase a duration of 1-6 months and 1-3 years. This mode provides an automatic renewal function. When checked, the purchase duration can be automatically renewed: 1-6 months and 1-3 years.
l The billing mode is pay-as-you-go, this option is hidden from selection.
(5) Deployment mode: single-AZ and multiple-AZ deployment. Currently, only single-AZ and three-AZ deployment are supported. For single-AZ deployment, select any AZ. For multi-AZ deployment, select three AZs, and the system will automatically distribute the broker nodes evenly to each AZ.
(6) Set the number of nodes, which can be 3/5/7/9. The number of nodes in RabbitMQ refers to the number of nodes in the RabbitMQ cluster. In a RabbitMQ cluster, multiple nodes can form a cluster, and each node is an independent RabbitMQ server instance.
(7) Select the host type from the drop-down menu. You can select general-purpose or computing-plus. General-purpose cloud server shares the CPU resources of the host, mainly providing basic level of vCPU performance, balanced computing, memory and network resources, with high cost-effectiveness, and supporting general-purpose business operations. Computing-plus cloud server exclusively uses the CPU resources of the host, with no CPU contention between instances and no over-allocation of resources, and is equipped with a new network acceleration engine to achieve strong stability performance close to that of physical server.
(8) Select instance specifications. DMS RabbitMQ provides three types of specifications, including general-purpose or computing-plus. For details, see ECS Specifications.
(9) Select storage space, including disk type and space.
l There are three types of disks available: high I/O, common I/O, and ultra-high I/O. Common I/O is suitable for scenarios with large capacity, medium read/write speeds, and low transaction processing. High I/O is suitable for mainstream high-performance and high-reliability application scenarios. Ultra-high I/O is suitable for read/write-intensive application scenarios with ultra-high IOPS and ultra-high bandwidth requirements. For more information about disk types, see EVS Specifications.
l Disk space starts at 100G and can be increased by a factor of 100.
(10) Select an existing VPC. If no VPC exists, click Create to jump to the VPC page to add one. For more information, refer to VPC.
(11) Select an existing subnet. If no subnet exists, click Create to jump to the subnet page to add one.
(12) Select an existing security group. If no security group exists, click Create to jump to the security group page to add one.
3. After filling in the above information, click Next to enter the fee confirmation page.
4. After confirming that the instance information is correct, submit the request.
5. On the instance list page, check whether the RabbitMQ instance is successfully created. It takes about 3 to 15 minutes to create an instance, and the instance status is Creating.
