What technologies are used by online casino platforms

Modern online casinos are built as distributed systems that combine dozens of components. Below is a complete analysis of the main technologies.

1. Frontend and Client

HTML5/CSS3 and JavaScript - for cross-browser rendering of slots and interfaces.

SPA frameworks (React, Vue. js, Angular) - dynamic lobbies and admin panels.

WebGL and Canvas - hardware acceleration of animations, particles and 2D/3D graphics.

PWA (Progressive Web Apps) - offline cache, push notifications, installation without an app store.

2. Backend and architecture

Microservices - division into gaming, payment, user, CRM and anti-fraud services.

Containerization (Docker) and orchestration (Kubernetes) - reliable scaling and automatic resource.

API gateway (NGINX, Kong, Ambassador) - single entry point, routing, rate-limiting.

3. Server languages and frameworks

Node. js/NestJS - high-performance asynchronous processing of bets and events.

Java/Spring Boot - reliable payment and settlement mechanisms.

Go - fast microservices with low latency.

Python/Django - analytical and administrative modules.

4. Data storage

Relational DBMS (PostgreSQL, MySQL) - transactional logic of balances, rates, payments.

NoSQL solutions (MongoDB, Cassandra) - storage of player sessions, cache data, game logs.

In-memory cache (Redis, Memcached) - acceleration of reading balances and sessions, blocking.

Data-warehouse (ClickHouse, Snowflake) - analytics of large volumes of bets, BI-dashboards.

5. Payment infrastructure

PSP integrations (WorldPay, Stripe, Adyen) and local gateways (PayID, POLi) - deposits and payments.

Crypto node (Bitcoin, Ethereum) and API aggregators (Coinbase, BitGo) - cryptocurrency reception.

PCI-DSS - certification for working with bank cards, tokenization.

6. Safety and compliance

TLS 1. 3/HTTPS - traffic encryption.

OAuth2/OpenID Connect - strong authentication and SSO.

WAF and DDoS protection (Cloudflare, AWS Shield).

SIEM systems (Splunk, ELK) - collection and analysis of security logs.

RNG audit (iTech Labs, eCOGRA, GLI) and AML monitoring.

7. DevOps и CI/CD

GitLab CI, Jenkins, GitHub Actions - automation of assembly, testing, deployment.

Infrastructure as code (Terraform, Ansible) - consistent management of environments.

Monitoring and alerting (Prometheus, Grafana, Datadog) - SLA control, health checks.

8. Analytics and AI

Stream analytics (Kafka, AWS Kinesis) - real-time processing of game events.

ML-models (Python, TensorFlow) - prediction of player behavior, anti-fraud, personalization.

BI platforms (Tableau, Looker) - visualization of metrics: hold, LTV, ARPU.

• Modern online casinos are built on a stack of web technologies, microservices and cloud infrastructure. Frontend SPA with WebGL animation, containerized backend microservices on Node. js, Java and Go, hybrid DBMS and in-memory cache, integration with payment gateways and cryptonodes, strict security standards and automated CI/CD ensure reliability, scalability and quick display of new functions.
