Deploy Secure Stack with DR Then Baseline Performance

Scenario

Use this workflow when launching a compliance-ready production web stack requiring immediate security hardening, cross-region disaster recovery, and automated alerting. After provisioning, run full-stack diagnostics to establish performance baselines and tune Alibaba Cloud Linux, ECS, and RDS before routing live traffic.

Integration steps

1. Initialize Terraform: Define alicloud_vpc, alicloud_security_group, and alicloud_instance (Alibaba Cloud Linux). Restrict security_group_rules to 443/80 and bastion SSH.
2. Provision DB & Storage: Add alicloud_db_instance and alicloud_oss_bucket. Set RDS backup_retention_period = 7 and enable cross-region sync.
3. Deploy SSL via CAS: Use alicloud_cas_certificate to upload certs, then bind to alicloud_slb_listener with frontend_port = 443 and certificate_id = alicloud_cas_certificate.my_cert.id.
4. Configure DR Policies: Apply alicloud_auto_snapshot_policy (schedule: 0 2 *, retention: 30 days). Enable RDS automated backups with backup_period = "Monday,Tuesday,Wednesday,Thursday,Friday,Saturday,Sunday".
5. Wire EventBridge Alerts: Create a rule: aliyun eventbridge PutRule --RuleName "ProdAlerts" --EventPattern '{"source":["acs.ecs","acs.rds"],"detail-type":["InstanceStatusChange","BackupFailed"]}' --TargetArn "arn:acs:notify:...:sms".
6. Run Diagnostics: SSH to ECS, run perf record -g -a -- sleep 60 and sysctl -w net.core.somaxconn=65535. Query RDS metrics: aliyun rds DescribeDBInstancePerformance --DBInstanceId <id> --Key "MySQL_IOPS,MySQL_QPS".
7. Tune & Validate: Update /etc/sysctl.conf with vm.swappiness=10. Run ab -n 10000 -c 100 https://<slb-ip>/ to verify latency <50ms.

Architecture

Traffic hits SLB, terminates SSL via CAS, and routes to ECS (Alibaba Cloud Linux). ECS stores static assets in OSS and queries RDS over private VPC endpoints. EventBridge ingests ECS/RDS metrics to trigger SMS/email alerts. DR relies on ECS auto-snapshots and RDS cross-region backups. Diagnostics run locally on ECS and poll RDS APIs to baseline throughput.

Prerequisites

• Alibaba Cloud CLI configured with RAM roles: AliyunECSFullAccess, AliyunRDSFullAccess, AliyunSLBFullAccess, AliyunEventBridgeFullAccess, AliyunCASFullAccess.
• Terraform v1.5+ with alicloud provider v1.200+.
• Valid SSL certificate/key for CAS.
• MLPS 2.0 compliance checklist (audit logs, encryption at rest).
• Pre-provisioned VPC and cross-region OSS bucket.

Common pitfalls

• SLB Health Check Drops: Missing SLB CIDR whitelisting in ECS security groups causes 503s. Explicitly allow SLB health check IPs on port 80/443.
• RDS Cross-Region Lag: Enabling cross-region backups without adequate primary IOPS causes replication delays. Monitor ReplicationDelay before enabling.
• EventBridge Pattern Mismatch: Incorrect source/detail-type in PutRule drops alerts. Validate against aliyun eventbridge ListEventBuses and test with SendEvent.
• Terraform State Corruption: Concurrent terraform apply on shared state breaks infrastructure. Always use OSS backend with lock_table enabled.
• Aggressive sysctl Tuning: Over-tuning net.ipv4.tcp_max_syn_backlog without load testing triggers OOM kills. Validate under simulated peak traffic first.

Typical questions

• deploy production stack with DR then baseline performance
• terraform provision secure infra then performance test
• deploy hardened stack with backup and tune performance
• full stack deploy with DR monitoring then diagnose slowness
• provision complete production environment then optimize
• 一键部署安全生产环境含容灾后性能诊断
• Terraform部署SSL容灾后进行性能基线测试
• deploy protect monitor then performance baseline

Q: How do I provision a secure production stack with disaster recovery using Terraform and then establish performance baselines? A: You use Terraform to provision a hardened production web stack with cross-region disaster recovery, then immediately run full-stack performance diagnostics to establish baselines and tune the infrastructure. This workflow deploys VPCs, ECS clusters, RDS, OSS, and SLB configured with SSL certificates, MLPS 2.0 compliance, and Event Bridge alerting before going live.
