Concepts, cloud service introduction, and terms:

• Elastic IP (EIP): EIP enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidth.
• Virtual Private Cloud (VPC): VPC enables you to provision logically isolated virtual private networks for cloud resources, such cloud servers, containers, and databases. You can create custom subnets, security groups, network ACLs, route tables, and assign EIPs and bandwidths.
• Elastic Cloud Server (ECS): An ECS is a basic computing unit that consists of vCPUs, memory, OS, and Elastic Volume Service (EVS) disks. After an ECS is created, you can use it just like a local computer or physical server.
