Virtual Private Cloud (VPC): an isolated and private virtual network environment. You can use VPC, along with EIP, Cloud Connect, and Direct Connect to establish a reliable, secure, and efficient communication channel for your cloud resources to communicate with each other, the internet, and on-premises networks.
Elastic Cloud Server (ECS): secure, scalable, on-demand computing resources that enable you to flexibly deploy applications and workloads.
Elastic Load Balance (ELB): automatically distributes incoming traffic across multiple servers to balance workloads, increasing service capabilities and fault tolerance of your applications.
Elastic IP (EIP): provides static public IP addresses and scalable bandwidths that enable your cloud resources to communicate with the Internet. You can easily bind an EIP to an ECS, BMS, virtual IP address, NAT gateway, or load balancer, enabling immediate Internet access.
