Service Relationship References
Virtual Private Cloud Virtual Private Cloud (VPC) provides an isolated, stable, secure, fast-deliverable, and controllable network environment for ECS. You have complete control over IP addresses and network topology within a VPC. VPCs are suitable for users who have high network security requirements. IP addresses of ECS instances in VPCs
Elastic IP Address Elastic IP addresses (EIPs) are NAT IP addresses that are located in the public gateway of Alibaba Cloud. By means of NAT gateways, EIPs are mapped to the primary elastic network interfaces (ENIs) of the ECS instances that are associated with the EIPs. You can associate EIPs with ECS instances that are located in VPCs to enable the instances to communicate over the Internet.
Server Load Balancer Server Load Balancer (SLB) distributes traffic across multiple ECS instances. Architecture
CloudMonitor CloudMonitor develops monitoring solutions for ECS instances, system disks, and public bandwidth.
Resource Access Management Resource Access Management (RAM) allows you to manage the identities and permissions of Alibaba Cloud services and users to implement access control over ECS resources. RAM overview
Anti-DDoS Anti-DDoS Origin Basic is a service that protects ECS instances from DDoS attacks to ensure system stability. If inbound traffic to an instance exceeds the maximum traffic rate allowed by the instance type, Alibaba Cloud Security throttles the traffic. Anti-DDoS Basic
Security Center Alibaba Cloud Security Center provides ECS with basic security services such as unusual logon detection, vulnerability scan, and baseline check. You can check the security status of your ECS instances in the ECS console or in the Security Center console. Basic security services
Key Management Service The ECS disk encryption feature uses Key Management Service (KMS) to encrypt data stored in ECS instances.
Auto Scaling Auto Scaling (ESS) adjusts the number of ECS instances based on business and policy changes.
  • ESS adds ECS instances to ensure computing capabilities as business requirements increase.
  • ESS removes ECS instances to reduce costs as business requirements decrease.
Resource Orchestration Service You can create a stack template by using the Resource Orchestration Service (ROS) console or by calling ROS API operations. Then, you can use the template to quickly create and manage ECS resources. ROS overview
Operation Orchestration Service You can use the ACS-ECS-BulkyStartInstances public template of Operation Orchestration Service (OOS) to start multiple ECS instances at a time. Overview
ApsaraDB RDS ECS instances work with ApsaraDB RDS instances that reside within the same region as the ECS instances to build a typical service access architecture. This reduces network latency and Internet traffic fees and ensures the optimal performance of ApsaraDB RDS instances. How do I access an RDS instance from an ECS instance over the intranet?
Container Service for Kubernetes Container Service for Kubernetes (ACK) uses Docker containers to manage application lifecycles on groups of ECS instances.
Dedicated Host You can deploy ECS instances on a dedicated host and gain exclusive access to its physical resources. Dedicated Host allows you to redeploy your business or migrate your business to the cloud at minimal costs. ECS instances deployed on dedicated hosts meet strict regulatory compliance requirements.
Server Migration Center You can use Server Migration Center (SMC) to migrate ECS instances within an Alibaba Cloud account or across Alibaba Cloud accounts. Migrate servers
Alibaba Cloud Marketplace Alibaba Cloud Marketplace is a platform where third-party partners provide various software and services such as software infrastructure, business software, website construction, hosted O&M, cloud security, data, API operations, and solutions for ECS.
