An ECS is a computing server that provides CPUs, memory, images, and Elastic Volume Service (EVS) disks and allows on-demand allocation and elastic scaling. ECS integrates VPC, virtual firewalls, and multi-data-copy features to build an efficient, reliable, and secure computing environment that ensures service stability and continuity.
In CCE, a node is an ECS with multiple EVS disks (one 40-GB system disk and at least one data disk). You can specify ECS specifications when creating a node.
EVS provides persistent block storage for services such as ECS. You can attach EVS disks to an ECS and expand the EVS disk capacity.

Scalable File Service (SFS) provides high-performance file storage that is scalable on demand. It can be shared with multiple ECSs.
A VPC is an exclusive logical network. In a VPC, you can customize the security group, VPN, IP address segments, and bandwidth. You can manage and configure internal networks and modify network configurations, simplifying network management. You can also customize ECS access rules within the security group and between security groups to strengthen security protection.
For network security purposes, all container clusters created on CCE run in VPCs.
The ELB service automatically distributes access traffic to multiple ECSs to balance their service load.
CCE allows applications to work with ELB to improve fault tolerance and service availability of applications.
