Concepts, cloud service introduction, and terms:

Elastic Cloud Server (ECS): ECS provides secure, scalable, on-demand compute resources, enabling you to flexibly deploy applications and workloads.
Elastic IP (EIP): EIP enables your cloud resources to communicate with the Internet using static public IP addresses and scalable bandwidth. EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, load balancers, and NAT gateways.
Virtual Private Cloud (VPC): A VPC is an isolated and private virtual network environment. You can configure IP address segments, subnets, and security groups, as well as assign elastic IP addresses and allocate bandwidth in a VPC.
Security group: A security group is a collection of access control rules for ECSs that have the same security protection requirements and are mutually trusted in a VPC. After you create a security group, you can create different access rules for the security group to protect the ECSs that are added to that security group.
