Ambry is an open source, geodistributed, highly available, and horizontally scalable object store built at LinkedIn. It is an active-active, immutable, eventually consistent handle store that can be configured to provide stronger read-after-write consistency without additional latency overhead. At LinkedIn, Ambry runs on hundreds of nodes spanning multiple data centers and is the source of truth for media and other immutable content. The focus of this talk will be the architecture of Ambry and how the design decisions help it scale for both large and small objects. It will also cover how Ambry helped solve the main pain points of LinkedIn’s legacy media store. Finally, LinkedIn will talk about the roadmap and about getting involved in this open source initiative.
