An elastic cloud server is a computing server that provides CPUs, memory, images, and Elastic Volume Service (EVS) disks and that allows on-demand allocation and elastic scaling. The ECS service integrates Virtual Private Cloud (VPC), virtual firewalls, and multi-data-copy features to build an efficient, reliable, and secure computing environment, ensuring that your services run stably and continuously.
In CCE, a node is an elastic cloud server with multiple EVS disks (one 40-GB system disk and at least one user data disk). You can specify elastic cloud server specifications (flavor) when creating a node.
You can attach EVS disks to an elastic cloud server and expand the EVS disk capacity.

A VPC is an exclusive logical network that is completely isolated. In a VPC, you can customize the security group, VPN, IP address segments, and bandwidth. You can manage and configure internal networks and change 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 by CCE run on VPCs.
CCE allows applications to work with ELB to improve fault tolerance and service availability of applications.
OBS is an object-based storage service that provides customers with massive, secure, reliable, and cost-effective data storage capabilities, such as bucket creation, modification, and deletion, as well as object upload, download, and deletion.
CCE uses OBS to store the private container images uploaded by users.
CTS provides you with a history of operations performed on cloud service resources. With CTS, you can query, audit, and backtrack operations. The traces include the operation time, resource objects, resource IDs, requesters' IP addresses, and responses.
Currently, CTS records the following operations on CCE resources:
CCE resources include nodes, container clusters, container images, containerized applications, component templates, and graphical application designs.
