For an online casino to work quickly, reliably and ready for loads, a modern DevOps infrastructure is needed. Technologies such as CDN, caching, containerization (Docker) and orchestration (Kubernetes) allow for high availability, faster response, and easier scaling. Below is how it is implemented and why all this is needed.
CDN (Content Delivery Network)
Why do I need a CDN:- Accelerates site and WebApp downloads for players worldwide
- Reduces the load on the primary server
- Improves high traffic stability
- Can protect against DDoS
- Cloudflare
- Bunny CDN
- AWS CloudFront
- Fastly
- Static distribution (JS, CSS, images, banners)
- Caching pages with bonuses, landing pages
- HTTPS and WAF (firewall) support
Caching
What is cached:- Game statistics and account data
- Bonus and stock configurations
- Frequently called API responses (e.g. provider list)
- Redis (in memory, for speed)
- Varnish (caching HTTP responses)
- Memcached (alternative to Redis)
- Quick responses for players
- Reduce database load
- Improved scalability
Docker: Casino containerization
What Docker gives:- Packaging of components in insulated containers
- Convenient deploy: the same code works everywhere
- Easily scale and manage constraints
- Ability to deploy dev/stage/prod environments
- `auth-service`, `game-service`, `payment-gateway`
- `frontend`, `admin-panel`, `postgres-db`, `redis-cache`
Kubernetes: Production-level orchestration
Why Kubernetes is needed:- Managing a large number of Docker containers
- Automatic Scaling (HPA)
- Self-healing (if the service is down - it restarts)
- Load balancing between nodes
- Updates without downtime (rolling updates)
- AWS EKS
- Google GKE
- Hetzner with RKE or k3s
- DigitalOcean Kubernetes
Combined architecture
| Component | Technology |
|---|---|
| Statics | CDN (Cloudflare, Bunny) |
| Sessions and cache | Redis, Memcached |
| Containerization | Docker |
| Orchestration | Kubernetes + Helm + Ingress NGINX |
| Monitoring | Prometheus + Grafana |
| CI/CD | GitHub Actions / GitLab CI |
Results of use
Up to 50-70% responsiveness
Increased fault tolerance- Ability to deposit updates without stopping games
- Flexible scaling during peak hours
- Easy connection of new modules, games, providers
CDN, caching, Docker and Kubernetes are the backbone of the modern online casino tech platform. These technologies allow you to run a stable, fast and scalable product, ready for millions of users, many games and flexible infrastructure. This is not just "fashionable" - it is a quality standard for a reliable casino platform.
