Comments from XW: Let's take a look at the architecture of FB. It will be of reference significance for building large websites in the future!
Facebook is the world's leading social network platform. It uses a lot of open-source software.Programming LanguageIncluding Java, Ruby, PHP, Python, and objective-C. The following is a detailed list of open source software that Facebook is using or contributing:
Apache cassandraYesIAn Open-Source Distributed Key-value storage system. It was initially developed by Facebook to store extremely large data.
MySQLThis does not need to be discussed. It is the most widely used open source database.

ScribeThe aim is to help Facebook process a large amount of data on the server, as described on the scribe page, "Use scribe if you frequently access Facebook. Specifically, scribe is a server that collects website logs in real time.
ThriftIs a scalable cross-language service development framework. The key-value storage server Cassandra uses thrift as its client API.
FlashcacheIt is a MySQL Cache Optimization Module Suitable for general application scenarios.
HadoopIt is not just a distributed file system for storage, but a framework designed to execute distributed applications on a large cluster composed of general computing devices.
HiveIs a hadoop-based data warehouse platform. With hive, we can easily perform ETL work. Hive defines a query language similar to SQL: hql, which can convert user-written QL into corresponding mapreduceProgramHadoop-based execution.
Open Graph ProtocolTurn Any web page into a social graph.
