Preparing an ECS
Preparing an ECS
For details about how to purchase an ECS, see "ECSs" > "Purchasing an ECS" in the User Guide.
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 in Virtual Private Cloud.
- The ECS must have the same security group as the CloudTable cluster.
For more information about security groups, see Security > Security Group > Security Group Overview in the Virtual Private Cloud User Guide.
NoteWhen 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 creating 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 "ECSs > Logging In to a Linux ECS > Login Using an SSH Password" in the Elastic Cloud Server User Guide.
