Architecture and Technical Stack

Architecture and technical stack of online casinos

A modern online casino is not just a gaming site, but a complex ecosystem that combines backend infrastructure, gaming providers, payment gateways, analytics and security. The performance, scalability and sustainability of the project depend on the correctly selected architecture and technical stack.

Core Architecture Components

1. Frontend (user interface)
- Website and WebApp: React, Vue. js, Tailwind CSS
- Adaptability for mobile devices
- Integration with gaming iframe, payment forms, live chat

2. Backend (server logic)
- Languages: Node. js, PHP (Laravel), Python (FastAPI), Go
- REST/GraphQL API for front interaction
- Microservice architecture with Docker and Kubernetes (as you grow)

3. Database
- PostgreSQL, MySQL, Redis for cache
- Storage of user data, transactions, bets, bonuses
- Encryption and backup

4. Game providers
- Integration via aggregators (SoftSwiss, Slotegrator, EveryMatrix)
- Support for slots, live games, crash, board games
- Connection via API/iframe taking into account the player's balance

5. Payment system
- Wallets: cryptocurrencies (TON, USDT, BTC), cards, P2P
- Connection via API: CoinsPaid, Cryptomus, Mercuryo, PayTR, etc.
- Support for automatic deposits/withdrawals, transaction verification

6. Authorization system and accounts
- Email/Telegram/SMS/ Web3 authorization
- Sessions, tokens, multi-account protection
- Built-in support for KYC and limits

7. Admin (back office)
- Manage users, bonuses, transactions
- KYC moderation, game and stock customization
- Dashboards with analytics and logs

8. Safety
- DDoS protection, fraud logic, IP/geo filters
- Using TLS, password hashing, 2FA
- Suspicious activity monitoring and logging

Technology Stack Example

Level	Technology
Frontend	React, Vue, Tailwind, WebSocket
Backend	Node. js, PHP (Laravel), Go, Python
DB and cache	PostgreSQL, Redis, ClickHouse
Infrastructure	Docker, NGINX, CDN, AWS/Hetzner/GCP
CI/CD	GitHub Actions, GitLab CI, Ansible
Security	Fail2Ban, WAF, Let's Encrypt

Scalability

Use containerization and orchestration for flexibility
Distributed infrastructure with CDN and geo-mirrors
Horizontal scaling of game modules and APIs
Dedicated clusters for heavy providers (e.g. Live casinos)

Architecture and tech stack is the foundation of online casinos. A properly built system allows the project to scale, be safe, work quickly and meet the requirements of both players and regulators. Technology must not only work, but also be prepared for stress, updates and global growth.
