The Linux Foundation last week announced that it will host Valkey, a fork of the Redis in-memory data store. Valkey is backed by AWS, Google Cloud, Oracle, Ericsson and Snap.

AWS and Google Cloud rarely back an open-source fork together. Yet, when Redis Labs switched Redis away from the permissive 3-clause BSD license on March 20 and adopted the more restrictive Server Side Public License (SSPL), a fork was always one of the most likely outcomes. At the time of the license change, Redis Labs CEO Rowan Trollope said he “wouldn’t be surprised if Amazon sponsors a fork,” as the new license requires commercial agreements to offer Redis-as-a-service, making it incompatible with the standard definition of “open source.”
