In the ever-evolving world of technology, databases play a critical role in managing and storing the vast amounts of data generated by users every second.
Different tech giants use various database technologies to meet their specific performance, scalability, and reliability requirements.
In this article, we’ll explore the databases used by web developers for YouTube, Telegram, Facebook, Netflix, Twitter, and Spotify.
YouTube - MySQL
YouTube, the world’s largest video-sharing platform, relies on MySQL for its primary database needs. MySQL, an open-source relational database management system, is known for its reliability, speed, and scalability, making it ideal for handling the massive amounts of video metadata, user data, and content records YouTube generates. Google, which owns YouTube, has customised MySQL for enhanced performance, integrating it with their distributed storage systems like Bigtable and Colossus for better global data distribution.
Why YouTube Uses MySQL
- Scalability – MySQL can handle the high volume of transactions required for video uploads, comments, and search queries.
- Reliability – It ensures data consistency and availability across multiple data centres.
- Flexibility – MySQL integrates seamlessly with other Google technologies, allowing YouTube to customise its infrastructure for optimal performance.
Telegram - MongoDB
Telegram, the popular messaging app known for its speed and security, uses MongoDB as its primary database. MongoDB is a NoSQL, document-oriented database that offers flexibility and high-speed data processing, making it well-suited for handling billions of real-time messages.
Why Telegram Uses MongoDB
- High Performance – MongoDB can handle massive real-time data streams with low latency.
- Schema Flexibility – It supports flexible data models, which is ideal for storing unstructured message data.
- Horizontal Scalability – MongoDB’s sharding capabilities allow Telegram to scale horizontally across multiple servers, ensuring a seamless user experience.
Facebook - MySQL
As one of the largest social media platforms in the world, Facebook relies heavily on MySQL for its primary database needs. However, Facebook has significantly modified MySQL to meet its unique scalability and performance demands.
Why Facebook Uses MySQL
- Scalability – Custom sharding and partitioning methods allow Facebook to manage billions of active users efficiently.
- Data Integrity – MySQL provides robust ACID compliance, ensuring data consistency and reliability.
- Custom Optimisations – Facebook has developed its own MySQL storage engines, like RocksDB, to improve read and write performance.
Netflix - Apache Cassandra
Netflix, the global streaming giant, uses Apache Cassandra for its primary database system. Cassandra is known for its high availability, fault tolerance, and scalability, which aligns perfectly with Netflix’s need to stream content to millions of users worldwide.
Why Netflix Uses Apache Cassandra
- High Availability – Cassandra’s decentralised architecture ensures no single point of failure.
- Global Scalability – It can efficiently replicate data across multiple geographic regions.
- Fast Data Access – Cassandra is designed for fast write and read operations, making it ideal for real-time streaming data.
Twitter (X) - MySQL
Twitter (X), the microblogging platform known for real-time updates, also relies on MySQL as its main database. Over the years, Twitter has developed custom tools and strategies to optimise MySQL for real-time performance.
Why Twitter Uses MySQL
- Consistency and Durability – MySQL ensures that tweets are reliably stored and accessible.
- High Write Throughput – MySQL’s InnoDB engine is optimised for high-speed data writes.
- Mature Ecosystem – Twitter benefits from the extensive MySQL ecosystem, including replication and backup tools.
Spotify - Apache Cassandra
Spotify, the world’s leading music streaming platform, uses Apache Cassandra for its distributed database needs. Like Netflix, Spotify benefits from Cassandra’s ability to handle high-throughput data with low latency.
Why Spotify Uses Apache Cassandra
- Distributed Architecture – Cassandra’s decentralised design supports Spotify’s global infrastructure.
- Scalability – It can manage the massive volume of user data, playlists, and song metadata.
- Low Latency – Cassandra’s fast read and write capabilities enhance the real-time music streaming experience.
Conclusion
From social media to music and video streaming, each of these tech giants has chosen its database technology based on specific requirements, including scalability, data consistency, and performance. Understanding these choices helps illustrate how critical databases are to modern digital infrastructure.
