    Microservices Engine:Create a Nacos engine

    Last Updated:Nov 24, 2023

    Before you use a Nacos engine to implement features for applications, such as service discovery and configuration management, you must purchase, create, and maintain the required resources. If you use a Microservices Engine (MSE) Nacos engine, you need only to focus on the location, version, network type, and specifications of the Nacos engine. You do not need to focus on the creation and maintenance of the Nacos engine. MSE allows you to focus more on your business. This topic describes how to create an MSE Nacos engine for applications.

    Procedure

    Important

    By default, authentication is disabled for new Nacos engines. We recommend that you enable authentication and disable the public IP address whitelist for engines after you purchase and test the engines. This way, the security of the engines is ensured. For more information, see Access authentication by the Nacos client and Configure a public IP address whitelist.

    1. Go to the page for creating an MSE instance.
      • MSE is not activated.
        1. Go to the MSE product page.
        2. On the MSE product page, click Buy Now. Then, click the Microservice Registry tab.
        3. Create an MSE instance. Select ZooKeeper or Nacos for Engine Type based on your business requirements.

          A page is displayed for you to create or purchase an MSE instance.

      • MSE is activated.
        1. Log on to the MSE console.
        2. In the left-side navigation pane, choose Microservices Registry > Instances.
        3. On the Instances page, click Create Instance.
    2. Select a billing method.

      MSE supports the subscription and pay-as-you-go billing methods. If you want to use an MSE instance for more than one month, we recommend that you use the subscription billing method. If you use the pay-as-you-go billing method, you are billed on an hourly basis.

    3. Select a region based on the region where the MSE instance resides.
      Note For more information about the regions supported by MSE, see Supported regions.
    4. Configure the basic information about the engine.
