DaaS / Products / Automated ECS Operations and DR Setup

Automated ECS Operations and DR Setup

Provision and configure Alibaba Cloud Linux ECS instances at scale, use Cloud Assistant to remotely execute configuration and maintenance scripts across the fleet, and set up automated snapshot and disk backup policies for disaster recovery — forming a complete compute operations pipeline from provisioning to protection.

Products involved

Scenario

Use this workflow when deploying a scalable fleet of Alibaba Cloud Linux (Alinux) instances that require zero-touch baseline configuration and automated disaster recovery. It is ideal for CI/CD pipelines, batch clusters, or stateless services where consistent performance tuning and guaranteed point-in-time data protection must be enforced programmatically.

Integration steps

Provision Alinux fleet (alinux-manage-lifecycle): Launch instances with Cloud Assistant pre-enabled.

   aliyun ecs RunInstances --RegionId cn-hangzhou --InstanceType ecs.c7.large \
     --ImageId aliyun_3_x64_20G_alibase_20231215.vhd --Amount 5 \
     --SecurityGroupId sg-xxx --VSwitchId vsw-xxx --InstanceName "alinux-prod"

Define configuration script (ecs-execute-instances): Create a reusable Cloud Assistant command for Alinux tuning.

   aliyun ecs CreateCommand --Type RunShellScript --Name "alinux-tune" \
     --CommandContent "echo 'vm.swappiness=10' >> /etc/sysctl.conf && sysctl -p && yum-config-manager --enable alinux3-plus"

Execute across fleet: Push the command to target instances without SSH.

   aliyun ecs InvokeCommand --CommandId cmd-xxx --InstanceIds '["i-001","i-002","i-003"]'

Create DR snapshot policy (ecs-manage-recovery): Define automated backup rules.

   aliyun ecs CreateAutoSnapshotPolicy --RegionId cn-hangzhou --Name "dr-daily" \
     --RetentionDays 30 --TimePoints '["02:00"]' --RepeatWeekdays '[1,2,3,4,5,6,7]'

Attach policy to disks: Bind the policy to system/data disks.

   aliyun ecs ApplyAutoSnapshotPolicy --RegionId cn-hangzhou --AutoSnapshotPolicyId sp-xxx \
     --DiskIds '["d-001","d-002","d-003"]'

Verify pipeline: Check execution logs and policy status.

   aliyun ecs DescribeInvocationResults --InvokeId inv-xxx
   aliyun ecs DescribeAutoSnapshotPolicyEx --AutoSnapshotPolicyId sp-xxx

Architecture

The control plane orchestrates three layers: (1) Provisioning (RunInstances) spins up Alinux nodes in a VPC. (2) Configuration routes payloads through the Cloud Assistant API; the pre-installed agent on each instance receives InvokeCommand requests, executes them locally, and returns stdout/stderr to the ECS console. (3) Protection hooks into the Block Storage service, where CreateAutoSnapshotPolicy schedules incremental disk captures. Snapshot metadata flows to the ECS API, while actual data is stored in isolated OSS-backed volumes, decoupling compute from backup storage.

Prerequisites

Alibaba Cloud CLI (aliyun) configured with valid AccessKey/SecretKey
RAM policy granting AliyunECSFullAccess and AliyunCloudAssistantFullAccess
Target VPC, vSwitch, and Security Group IDs
Alinux 3.x image ID (e.g., aliyun_3_x64_20G_alibase_20231215.vhd)

Common pitfalls

Agent offline/DNS failure: InvokeCommand fails with AgentNotOnline if instances lack outbound internet or VPC DNS. Attach a NAT Gateway or configure resolv.conf via UserData.
Inconsistent multi-disk backups: Applying policies per-disk instead of using CreateSnapshotGroup causes application-level inconsistency during restore. Always group related disks.
YUM repo timeouts: Alinux default mirrors may be unreachable in isolated VPCs. Pre-bake internal mirror configs or use --CommandContent to swap repos before package installs.
Snapshot quota exhaustion: Auto-policies count toward the 64-snapshot-per-disk limit. Overlapping policies or excessive RetentionDays will silently block new backups.

FAQ

Q: How do I automate ECS provisioning, configuration, and disaster recovery backups? A: You can automate ECS provisioning, configuration, and disaster recovery by using the Alibaba Cloud CLI to launch instances, push baseline scripts via Cloud Assistant, and apply automated snapshot policies. This programmatic workflow ensures zero-touch tuning and consistent point-in-time backups across your entire fleet without manual SSH access.
