Instagram System Design

Instagram System Design

Designing a system like Instagram involves a complex network of components and services.

Here’s an overview of Instagram’s system:

Client Interaction: Users engage through mobile or web apps.

Load Balancer: Distributes requests evenly to API gateways.

API Gateways: Routes requests to microservices.

Write Operations: Directs uploads and comments to the App Server, which validates requests, writes data, and handles video processing.

Feed Generation Service:Generates and updates user feeds.

Read Operations: Routes read operations, like viewing feeds, to relevant services.

Metadata Database: Stores user profiles and post data.

Caching Mechanism: Utilises Redis or Memcached for data caching, reducing latency and database load.

Search Service (Elasticsearch): Efficiently performs user and content searches.

Blob Storage: Stores user-uploaded media (images, videos).

CDN (Content Delivery Network): Caches and serves static content with low latency.

Video Processing: Processes user-uploaded videos (transcoding, resizing, thumbnails).

Notifications: Notifies users of likes, comments, and interactions.

Instagram’s architecture may involve additional services for monitoring, analytics, backup, recovery, scalability, performance, and reliability.
