Instagram has evolved significantly since its launch in 2010, overcoming early scalability challenges and transforming to support over a billion users. Key strategies included migrating from AWS to Facebook’s data centers, implementing distributed databases, and optimizing caching mechanisms. The platform uses Django for its web framework, RabbitMQ for message brokering, and Celery for asynchronous task processing. Their backend architecture and deployment models incorporate continuous integration and automated monitoring, ensuring high performance and reliability.

My opinion is that Meta likely has data centers that are more tailored to its specific needs compared to AWS, which offers generalized cloud services for a wide range of clients. Meta’s data centers are optimized for handling the unique demands of social networking platforms, such as massive real-time photo and video uploads, high user engagement, and global scalability.
It’s like after creating my own app, I can choose from cloud services to host my app’s server (generic), or invest in having my own server tailored for my app (specific). Anyway, thank you for sharing this topic!

If you listen to online coding elitists you might get the impression that only Go and Rust are serious and viable options to build a backend.
Instagram has a billion users and uses a Python Framework. Hopefully this serves as an example as to why you should take this kind of permanently online take with a grain of salt.
