Ok I want you to write a system that can write hundreds of thousands of messages per second, and read millions of messages per second, globally and with low latency, with every message being permanently stored and available for query. Till need you design and implement redundancy and fault tolerance. You’ll need a strategy for backing up everything. You’ll need to be able to deploy code updates to your global infrastructure which is self managed because running this in a cloud would be ridiculously expensive. You’ll need video ingestion systems, monitoring and alerting. You’ll need advertising systems, billing systems, content moderation systems, anti spam and anti bot systems. You’ll need to implement an API for developers. You’ll need applications for mobile and web. You’ll need developers to do this, testers to test it, people to organize all this stuff.
