Handling Media at LinkedIn’s Scale
To build a world-class media infrastructure, the team focuses on three areas:
- Quality of experience for our 675M+ members
- Cost efficiency of our infrastructure
- Creating a platform within LinkedIn that is easy to use, scalable and can be leveraged for future projects
Our infrastructure uses both in-house data systems (Espresso, Ambry, Kafka) and the public cloud (Azure).
