Instagram, boasting over 2 billion users, is a powerhouse of innovation, and its success hinges on a robust and scalable architecture. Let’s explore some key components:
Microservices Architecture: Instagram leverages microservices for independent, modular development. This enables flexible scaling of individual components based on demand.
Global Content Delivery Network (CDN): A robust CDN ensures fast and reliable content delivery for users worldwide. Caching frequently accessed data at geographically distributed edge locations minimizes latency and improves user experience.
Tech Stack Powerhouse: Instagram utilizes a diverse mix of technologies to handle various tasks:
Frontend: React (UI framework), GraphQL (API querying), Native mobile development with Swift (iOS) and Kotlin (Android)
Backend: Django (web framework), Gunicorn (web server)
Data Storage: Memcached (in-memory caching), PostgreSQL (relational database), Cassandra (NoSQL database for high-volume data), CockroachDB (distributed SQL database for scalability)
Messaging/Streaming: Apache Kafka (distributed streaming platform), Scuba (Facebook-developed messaging system)
Data Processing: Spark (large-scale data processing), Presto (ad-hoc SQL querying), Scuba (for internal data pipelines)
DevOps: Kubernetes (container orchestration), Docker (containerisation), ELK Stack (log management), Prometheus (monitoring).
