    Enterprise Distributed Application Service:Create an ECS instance

    Last Updated:Feb 27, 2026

    Enterprise Distributed Application Service (EDAS) deploys applications on Elastic Compute Service (ECS) instances within ECS clusters. You must create the required ECS instances before you deploy an application.

    Prerequisites

    • VPC required: If you purchased an ECS instance for the first time after 17:00 (UTC+8) on June 14, 2017, you can select only the Virtual Private Cloud (VPC) network type. The classic network type is no longer available for new purchases after this date. You can continue to use existing ECS instances that were created with the classic network type before this date.

    • VPC ready: To create an ECS instance in a VPC, you must select a specific VPC during instance creation. If you do not have a VPC, create one first. For more information, see Create an IPv4 VPC.

      Important

      After the ECS instance is created, you cannot transfer it to a different VPC. Make sure that you select the correct VPC.

    Procedure

    1. Log on to the EDAS console.

    2. In the left-side navigation pane, choose Resource Management > ECS.

    3. In the top navigation bar, select the region in which you want to create an ECS instance.

    4. (Optional) In the upper part of the page, select a microservices namespace from the Microservices Namespace drop-down list.

    5. In the upper-right corner of the page, click Create Instance.

    6. On the ECS buy page, purchase an ECS instance. For more information, see Create an instance by using the wizard.

      Important

      To use or manage an ECS instance in the EDAS console, you must install EDAS Agent on the instance. EDAS Agent is automatically installed if you select the EDAS base image when you purchase the instance. To select the EDAS base image, perform the following steps:

      1. In the Image section, select Marketplace Images, and then click Select Image from Alibaba Cloud Marketplace (with Operating System).

      2. In the Alibaba Cloud Marketplace dialog box, enter EDAS in the search box, and then click Search.

      3. In the search results, select a version for the EDAS International image and click Use. The latest version is selected by default.

    7. Wait for the instance to be created. This process takes approximately 1 to 5 minutes.

    Verify the result

    1. Click Console to return to the Alibaba Cloud Management Console.

    2. Go to the ECS console and check the status of the ECS instance.

    3. When the status of the ECS instance changes to Running, the instance is created.
