Scaling services with Shard Manager

Scaling services with Shard Manager

We look at how Shard Manager is fully integrated in Facebook’s infrastructure ecosystem and provides a holistic, end-to-end solution supporting basic shard failover as well as sophisticated load balancing, shard scaling, and operational safety. Over the years, as we’ve expanded in scale and functionalities, Facebook has evolved from a basic web server architecture into a complex one with thousands of services working behind the scenes. It’s no trivial task to scale the wide range of back-end services needed for Facebook’s products.

And we found that many of our teams were building their own custom sharding solutions with overlapping functionalities. To address this problem, we built Shard Manager as a generic platform that facilitates efficient development and operation of reliable sharded applications.
