Buying a RabbitMQ Instance

RabbitMQ is an open-source service using the advanced message queuing protocol (AMQP). RabbitMQ stores and forwards messages in a distributed system.

RabbitMQ instances are tenant-exclusive, and physically isolated in deployment. You can customize the computing capabilities and storage space of a RabbitMQ instance as required.

This video shows how to purchase a RabbitMQ instance.

Preparing Required Resources

Dependency resources listed in Table 1 have been prepared.

Table 1 RabbitMQ instance dependencies

Resource Name

Requirement

Reference

VPC and subnet

You need to configure a VPC and subnet for the RabbitMQ instance as required. You can use the current account's existing VPC and subnet or shared ones, or create new ones.

VPC owners can share the subnets in a VPC with one or multiple accounts through Resource Access Manager (RAM). Through VPC sharing, you can easily configure, operate, and manage multiple accounts' resources at low costs. For more information about VPC and subnet sharing, see VPC Sharing.

Note: VPCs must be created in the same region as the RabbitMQ instance.

For details on how to create a VPC and subnet, see Creating a VPC and Subnet. If you need to create and use a new subnet in an existing VPC, see Creating a Subnet for an Existing VPC.

Security group

Different RabbitMQ instances can use the same or different security groups.

The security group must be in the same region as the RabbitMQ instance.

Before accessing a RabbitMQ instance, configure security groups based on the access mode. For details, see Table 2 or Table 3.

For details on how to create a security group, see Creating a Security Group. For details on how to add rules to a security group, see Adding a Security Group Rule.

EIP

To access a RabbitMQ instance on a client over a public network, create EIPs in advance.

Note the following when creating EIPs:

  • The EIPs must be created in the same region as the RabbitMQ instance.
  • The RabbitMQ console cannot identify IPv6 EIPs.

For details about how to create an EIP, see Assigning an EIP.

Buying a RabbitMQ Instance

DMS for RabbitMQ provides multiple options for you to purchase RabbitMQ instances.

Table 2 Purchasing a RabbitMQ instance

How to Purchase

Scenario

Quickly Configuring a RabbitMQ Instance

For a quick purchase, DMS for RabbitMQ offers preconfigured instance specifications.

Customizing a RabbitMQ 3.x.x Instance

For a standard purchase, you can customize a single-node or cluster RabbitMQ 3.x.x instance as required.

Customizing a RabbitMQ AMQP-0-9-1 Instance

For a standard purchase, you can customize a single-node or cluster RabbitMQ AMQP-0-9-1 instance as required.
  1. Go to the Buy Instance page.
  2. Set basic instance configurations on the Quick Config tab page.

    Table 3 Basic instance configuration parameters

    Parameter

    Description

    Billing Mode
    • Yearly/Monthly is a prepaid mode. You need to pay first, and will be billed for your subscription period.
    • Pay-per-use is a postpaid mode. You can pay after using the service, and will be billed for your usage duration. The fees are calculated in seconds and settled by hour.

    Region

    DMS for RocketMQ instances in different regions cannot communicate with each other over an intranet. Select a nearest location for low latency and fast access.

    AZ

    An AZ is a physical region where resources use independent power supply and networks. AZs are physically isolated but interconnected through an internal network.

    Select one AZ or at least three AZs. The AZ setting is fixed once the instance is created.

  3. Set the bundle.

    DMS for RabbitMQ provides preconfigured specifications. You can select one as required. Specify the disk type and capacity as required. The disk type is fixed once the instance is created.

    The disk supports high I/O, ultra-high I/O, Extreme SSD, and General Purpose SSD types. For more information, see Disk Types and Performance.

    Figure 1 Bundle

  4. Set the network.

    Table 4 Instance network parameters

    Parameter

    Description

    VPC

    Select a created or shared VPC.

    A VPC provides an isolated virtual network for your RabbitMQ instances. You can configure and manage the network as required. You can click Manage VPCs on the right to go to the VPC console, and view or create VPCs.

    After the RabbitMQ instance is created, its VPC cannot be changed.

    Subnet

    Select a created or shared subnet.

    After the RabbitMQ instance is created, its subnet cannot be changed.

    Security Group

    Select a created security group.

    A security group is a set of rules for accessing a RabbitMQ instance. You can click Manage Security Group to view or create security groups on the network console.

    Before accessing a RabbitMQ instance on the client, configure security group rules based on the access mode. For details about security group rules, see Table 2.

  5. Set the instance access mode.

    Table 5 Instance access mode parameters

    Parameter

    Description

    Public Network Access

    Clients can access RabbitMQ instances with public access enabled through elastic IP addresses (EIPs).

    Enabling public access requires EIPs. If EIPs are insufficient, click Create Elastic IP to create EIPs. Then, return to the RabbitMQ console and click next to Public IP Addresses to refresh the elastic IP address list.

    NOTE:
    • In comparison with intra-VPC access, enabling public access increases access latency and might lead to packet loss and jitter. Therefore, you are advised to enable public access only during the service development and testing phases.
    • If you manually unbind or delete an EIP on the VPC console, the public access function of the corresponding RabbitMQ instance is automatically disabled.

    Encryption Mode

    Enabling SSL secures data transmission with encryption.

    Once the instance is created, SSL cannot be manually configured.

  6. Set the instance authentication.

    Table 6 Instance authentication parameters

    Parameter

    Description

    RabbitMQ Authentication Username

    Enter the username used for accessing the instance.

    A username should contain 4 to 64 characters, start with a letter, and contain only letters, digits, hyphens (-), and underscores (_).

    Password

    Enter the password used for accessing the instance.

    A password must meet the following requirements:

    • Contains 8 to 32 characters.

    Enterprise Project

    Available for enterprise users.

    Enterprise projects facilitate project-level management and grouping of cloud resources and users. The default project is default.

    Tags

    Tags are used to identify cloud resources. When you have many cloud resources of the same type, you can use tags to classify cloud resources by dimension (for example, usage, owner, or environment).

    If your organization has configured tag policies for DMS for RabbitMQ, add tags to RabbitMQ instances based on the tag policies. If a tag does not comply with the tag policies, RabbitMQ instance creation may fail. Contact your organization administrator to learn more about tag policies.

    • If you have created predefined tags, select a predefined pair of tag key and value. You can click Create predefined tags to go to the Tag Management Service (TMS) console and view or create tags.
    • You can also create new tags by entering Tag key and Tag value.

    Up to 20 tags can be added to each RabbitMQ instance. For details about the requirements on tags, see Managing RabbitMQ Instance Tags.

    Description

    Set the description of the instance for up to 1024 characters.

    • Yearly subscriptions auto-renew for 1 year every time.

  9. Click Confirm.
  10. Confirm the instance information, and read and agree to the Huawei Cloud Customer Agreement. If you have selected Yearly/Monthly for Billing Mode, click Pay Now and make the payment as prompted. If you have selected the pay-per-use mode, click Submit.
  11. Return to the instance list and check whether the instance has been created.

    It takes 3 to 15 minutes to create an instance. During this period, the instance status is Creating.
    • If the instance is created successfully, its status changes to Running.
    • If the instance is in the Failed state, delete it by referring to Deleting a RabbitMQ Instance and try purchasing another one. If the purchase fails a second time, contact customer service.

  1. Go to the Buy Instance page.
  2. Set basic instance configurations on the Standard Config tab page.
