Deploy, Diagnose, and Protect Full Production Stack

Scenario

Use this workflow when provisioning a compliant, production-grade web application requiring IaC deployment, OS-level tuning, and enterprise resilience. It combines Terraform-driven infrastructure creation with Alibaba Cloud Linux optimization, automated SSL termination, cross-region DR, and event-driven monitoring for MLPS 2.0 compliance.

Integration steps

1. Initialize Terraform & Define Providers: Configure provider "alicloud" with credentials. Define resource "alicloud_vpc" and resource "alicloud_security_group" to establish isolated networking per terraform-provision-infrastructure.
2. Provision Core Stack: Run terraform apply. Declare resource "alicloud_instance" (image: aliyun_3_x64_20G_alibase_20231218.vhd), resource "alicloud_db_instance", resource "alicloud_oss_bucket", and resource "alicloud_slb_instance".
3. Apply Alinux Kernel Tuning: SSH into ECS and run sysctl -w net.core.somaxconn=65535 net.ipv4.tcp_tw_reuse=1. Persist via /etc/sysctl.d/99-alinux-prod.conf and execute tuned-adm profile network-throughput to baseline performance.
4. Bind CAS SSL to SLB: Request a cert via alicloud_cas_certificate. Attach to the HTTPS listener: resource "alicloud_slb_listener" "https" { backend_port = 80; server_certificate_id = alicloud_cas_certificate.cert.id; protocol = "https"; }.
5. Enable Cross-Region DR: Configure RDS async replication using ReplicationMode = "Async". Attach alicloud_auto_snapshot_policy to ECS disks for point-in-time recovery.
6. Deploy Monitoring & Automation: Create alicloud_cms_alarm for CPUUtilization > 85%. Route breaches to alicloud_event_bridge_rule to trigger auto-scaling or failover scripts.

Architecture

Inbound traffic hits SLB, where CAS terminates TLS and forwards to ECS. ECS runs hardened Alinux, processing logic while reading/writing to primary RDS and offloading assets to OSS. Cross-region RDS replication and ECS snapshots maintain DR state. CloudMonitor aggregates telemetry, while EventBridge routes threshold violations to automated remediation pipelines.

Prerequisites

• RAM user with AliyunECSFullAccess, AliyunRDSFullAccess, AliyunSLBFullAccess, AliyunCASFullAccess, and AliyunCMSFullAccess
• Terraform v1.5+ with terraform-provider-alicloud v1.215+
• Validated MLPS 2.0 baseline (audit logging, encryption at rest, least-privilege IAM)
• Primary/secondary regions with RDS/OSS availability

Common pitfalls

• Security Group Overlap: Default SGs block SLB health checks. Explicitly allow TCP:80/443 from SLB CIDR to ECS SG.
• CAS Propagation Delay: New certs take 5–10 minutes to sync. Use depends_on = [alicloud_cas_certificate.cert] to prevent listener failures.
• Kernel Tuning Conflicts: net.ipv4.tcp_tw_reuse=1 can disrupt legacy connection tracking. Validate with conntrack -L before applying in containerized workloads.
• Cross-Region RDS Latency: Synchronous replication degrades writes. Always use async replication and monitor ReplicationDelay via CloudMonitor.

Typical questions

• deploy full production stack with SSL then diagnose performance and add DR monitoring
• terraform provision hardened stack with RDS SSL then tune and add disaster recovery
• 一键部署生产环境含SSL性能诊断容灾和监控
• complete production deployment with HTTPS performance testing DR and CloudMonitor alerts
• provision secure web stack then baseline performance and add backup alerting
• Terraform部署加SSL加性能调优加容灾加告警完整方案
• deploy VPC ECS RDS SLB with HTTPS then troubleshoot and add cross-region DR
• automate full stack deploy with certs performance tuning and Event Bridge automation

Q: How do I deploy a secure production stack, diagnose its performance, and set up disaster recovery and monitoring? A: This workflow is executed by using Terraform to provision a hardened production web stack with VPC, ECS, OSS, SLB with SSL, and RDS under MLPS 2.0 compliance. The process continues with full-stack performance diagnosis and kernel tuning before layering on cross-region disaster recovery, CloudMonitor alerting, and Event Bridge automation.
