How to make the system Scalable?
The system employs several techniques to enable scalability:
- Database sharding and master-slave replication:
- The database uses sharding to partition data across multiple database servers based on the UserID.
- This distributes writes more evenly. Master-slave replication also creates read replicas that can handle read traffic, preventing overload on the master.
- Adding more slaves scales reads.
- Caching:
- Frequently accessed user name, badge, and point data is cached, reducing trips to the database.
- Compression allows more data to fit in the cache.
- As load increases, the cache can be scaled horizontally by adding more cache servers.
- Load balancing and horizontal scaling:
- A load balancer evenly distributes requests across multiple web servers.
- More web and application servers can be added easily to handle more traffic.
- Search engine:
- Elasticsearch is used for search to allow efficient querying.
- It scales well horizontally by distributing data and queries across shards. More shards can be added to scale search capacity.
- CDN for images:
- User images are stored on a CDN which is designed to scale dynamically to handle large traffic volumes spread across the globe.
- Asynchronous processing:
- Write requests are handled asynchronously for faster responses.
- The data is eventually consistent across the system.
- Microservices:
- Different components like authentication, read/write services are separated into distinct services that can scale independently as per demand.
Design a webpage that can show the status of 10M+ users including: name, photo, badge and points | System Design
We’ve got this huge community—over 10 million strong—and you want to build a webpage where everyone’s details, like their names, photos, those cool badges they’ve earned, and their points, can all be seen. That’s a massive load of information to handle. Achieving this goal necessitates an efficient and scalable system architecture capable of handling immense data volumes without compromising on performance or user experience.
