Overview
Cloud Infrastructure is Ventra Rocket's managed cloud service — designing, building, and operating cloud infrastructure for small and medium enterprises that want to modernize their IT stack without maintaining a dedicated in-house DevOps team. Ventra Rocket takes full ownership of the infrastructure lifecycle: architecture design, deployment, operations, and continuous optimization.
The service has supported 20+ clients with a total of 150+ services and microservices running on Ventra Rocket-managed infrastructure, consistently delivering a 99.99% uptime SLA — equivalent to under one hour of downtime per year.
The Challenge
Many Vietnamese businesses still run applications on bare-metal servers or unautomated VPS instances — deploying manually via FTP/SSH, with no monitoring, no backup strategy, and no disaster recovery plan. When incidents occur, recovery time (RTO) often stretches from hours to an entire day.
Moving to the cloud is not a simple "lift and shift" — applications need re-architecture to fully leverage cloud benefits: scalability, resilience, and cost efficiency.
Our Solution
Ventra Rocket applies Infrastructure as Code (IaC): all infrastructure is defined in code (Terraform + Docker Compose), version-controlled in Git, and fully reproducible in under 30 minutes from scratch.
The GitHub Actions CI/CD pipeline automates the entire flow from code commit to production: running tests, building Docker images, pushing to the container registry, and deploying with a zero-downtime rolling update strategy. Developers merge a PR — the system handles everything else.
Key Features
- Zero-downtime Deployment: Rolling updates with automatic health checks — new versions only reach production after passing health checks, with auto-rollback on failure.
- Comprehensive Monitoring: Prometheus + Grafana stack tracking 200+ per-service metrics, with intelligent alerting that distinguishes real incidents from false positives.
- Auto-scaling: Nginx load balancer + Docker Swarm scales horizontally under load and scales down when idle to minimize costs.
- Automated Backup: Daily database backups to S3 with 30-day retention, plus weekly automated restore tests to verify backup viability.
- Security Hardening: CIS benchmark configuration, Nginx WAF rules, SSL/TLS with Let's Encrypt auto-renewal, and scheduled vulnerability scanning.
Impact & Results
Clients achieve 99.99% uptime in their first year on Ventra Rocket-managed infrastructure — up from 97-98% previously (equivalent to 7-15 days of downtime per year). Deployment time dropped from 2-4 hours of manual work to 8 minutes automated.
Average infrastructure cost decreased 30% through right-sizing and auto-scaling — no more paying for idle resources on weekends and overnight. Development teams focus 100% on writing code instead of managing servers.
Tech Stack Details
Docker and Docker Compose standardize the runtime environment, eliminating environment-mismatch issues entirely. Nginx as reverse proxy and load balancer with configurations tuned for high throughput. GitHub Actions builds CI/CD pipelines natively integrated with GitHub repositories — no separate Jenkins server required. AWS (EC2, RDS, S3, CloudFront) provides enterprise-grade cloud infrastructure with strong SLAs and Singapore data center proximity for low-latency access from Vietnam.
