📈Facebook initially used a simple LAMP stack to host the entire platform.
🔀To scale to more users, Facebook partitioned its database by university.
🚀Separating application and database machines allowed Facebook to handle surges in user traffic more efficiently.
💾Facebook introduced a caching layer to reduce the load on the database servers.
🔧Custom modifications were made to the caching library to address scalability issues.
What was Facebook's original name?
—Facebook was originally called 'The Facebook'.
How did Facebook scale its system architecture?
—Facebook scaled its system architecture by partitioning the database, separating application and database machines, and introducing a caching layer.
What is horizontal scaling?
—Horizontal scaling is the process of adding more machines to handle increasing user traffic or workload.
What is caching?
—Caching is the process of storing copies of data in memory to speed up future data retrieval.
Did Facebook face any challenges during its system architecture evolution?
—Yes, Facebook faced challenges in handling surges in user traffic and optimizing the caching layer.
