Cryptocurrency Trading Platform for an International Startup
⚡ Pain Points We Tackled
An international startup engaged Azati to build a full-fledged cryptocurrency trading platform that would connect users to trading middleware, integrate multiple exchange data feeds (such as Binance, Bittrex, OKEx) and support algorithmic trading bots. The platform faced high-load requirements, strict request-rate limits from exchanges, and needed to operate at extremely low latency.
Our Approach
Azati's DevOps & infrastructure team played a central role: we architected a scalable cloud-native system on AWS, built infrastructure-as-code pipelines, implemented automated scaling & monitoring for thousands of exchange connections, and optimized request-handling through proxy micro-services. We partnered closely with the backend, trading logic, and security teams to ensure the platform met the demands of live cryptocurrency markets.
Applied Methods and Practices
- Infrastructure as Code (IaC): Designed and deployed cloud infrastructure with Terraform/CloudFormation for auto-scaling of trading-middleware nodes and proxy servers.
- Proxy Engine Microservice: Dynamically spun up AWS VMs to manage exchange request-rate limits, ensuring uninterrupted data ingestion.
- High-Availability & Fault Tolerance: Implemented self-healing nodes, monitoring (CloudWatch/Prometheus), and 24/7 alerting to maintain ~99.97% uptime.
- Optimized CI/CD Pipelines: Used Docker, Kubernetes/ECS, Blue/Green deployments, and automated testing for rapid, safe feature rollouts.
- Performance Tuning: Reduced latency in key request paths, optimized caching (Redis), WebSockets streaming, and PostgreSQL database performance (~37% improvement).
Solution Features
- Resilient & Scalable Cloud Infrastructure: Designed to support real-time cryptocurrency trading with high-load tolerance.
- Microservice Architecture: Modular services for exchange integrations, algorithmic trading bots, and real-time streaming via WebSocket API.
- Automated Infrastructure Management: Provisioning and teardown of resources to handle spikes and mitigate exchange throttling.
- Safe Deployment Pipelines: CI/CD with automated testing, deployment, rollback, and monitoring for high-risk trading operations.
- Real-Time Dashboards & Alerts: Continuous visibility into infrastructure health, trading latency, and system availability.
