destaques: - Fabric <http://fabric.readthedocs.org/en/1.3.3/index.html> is used to execute commands in parallel on all machines. A deploy takes only seconds. - PostgreSQL (users, photo metadata, tags, etc) runs on 12 Quadruple Extra-Large memory instances. - Twelve PostgreSQL replicas run in a different availability zone. - PostgreSQL instances run in a master-replica setup using Streaming Replication <https://github.com/greg2ndQuadrant/repmgr>. EBS is used for snapshotting, to take frequent backups. - XFS as the file system. Used to get consistent snapshots by freezing and unfreezing the RAID arrays when snapshotting. - Pgbouncer <http://pgfoundry.org/projects/pgbouncer/> is used pool connections <http://thebuild.com/blog/> to PostgreSQL. http://highscalability.com/blog/2012/4/9/the-instagram-architecture-facebook-bought-for-a-cool-billio.html -- Atenciosamente, Fábio Telles Rodriguez blog: http://www.midstorm.org/~telles/ e-mail / gtalk / MSN: [email protected] Skype: fabio_telles
