Preparing an ECS

Preparing an ECS

For details about how to purchase an ECS, see Purchasing an ECS.

To purchase an ECS, the following requirements must be met:

  • The ECS must have the same region, AZ, VPC, and subnet as the CloudTable cluster.

    For details about how to create a VPC, see User Guide > VPC and Subnet in Virtual Private Cloud.

  • The ECS must have the same security group as the CloudTable cluster.

    For more information about security groups, see Security Group in the Virtual Private Cloud User Guide.

    When cross-VPC communication is used to access a CloudTable cluster, the network administrator needs to authorize the access to the VPC, security group, and subnet where the cluster resides.

  • When purchasing an ECS, you need to set EIP to Automatically assign. Alternatively, you can bind an EIP to an ECS after the ECS is created.
  • To access a Linux ECS, you are advised to use an SSH password.

    For details about how to log in to a Linux ECS, see Logging In to a Linux ECS in the Elastic Cloud Server User Guide.
