In betting, everything is decided by scale: the number of matches, parallel live events, bets per second and unique users. The platform should be ready for sharp peaks in the load - during finals, derbies, world championships. That is why scaling through Kubernetes, cloud solutions (AWS) and global CDNs is becoming a key element of the architecture.
Why scaling is critical
Instant response when live bidding- Geographically distributed traffic from different continents
- Peak attendance spikes and events
- Real-time update of coefficients
- No downtime - every second = money
Kubernetes (K8s)
Container orchestration for on-demand scaling:- Autoscaling
- Horizontal scaling of microservices (rates, calculations, API)
- Blue/Green deploy and zero-downtime updates
- Multicluster architecture support for load isolation
- Built-in self-healing and monitoring mechanisms
AWS and Cloud Solutions
AWS, GCP, Hetzner, DigitalOcean - for flexible deployment and backup:- Elastic Load Balancer и Auto Scaling Groups
- S3 and Glacier - for storing reports, logs, backups
- Amazon RDS, Aurora - Scalable Databases
- CloudFront, WAF - security, caching, faster access
- Using Terraform to Manage Infrastructure as Code (IaC)
CDN - Worldwide Speed
Content Delivery Network allows you to deliver content instantly:- Fast loading of the site and coefficients for users from any country
- Caching images, scripts, frontend parts
- DDoS protection, edge filtering and geo-constraints
- Using Cloudflare, Akamai, Fastly, Bunny CDN
Typical Scaling Scenarios
| Scenario | Decision |
|---|---|
| Traffic spike on live | HPA in Kubernetes + automatic addition of pods |
| Increase GEO coverage | Deploying edge nodes and CDNs |
| Load split | Isolation of services (rates, calculations, UX) in clusters |
| Working with Big Data and BI | Splitting streams through Kafka and ClickHouse |
| A/B tests and releases | Canary/Blue-Green deployment через Helm/K8s |
Scaling is not an optional feature, but the basis for the stable operation of the betting platform. Kubernetes gives flexibility, AWS - power, CDN - global speed. Only with their correct combination can you ensure continuous operation, instant rates, protection against overloads and growth without borders.
