Redis, the popular in-memory data store, is switching away from the open source three-clause BSD license. Instead, in a move that is clearly aimed to prevent the large cloud providers from offering free alternatives to Redis’ own hosted services, Redis will now be dual-licensed under the Redis Source Available License (RSALv2) and Server Side Public License (SSPLv1). Under this new license, cloud service providers hosting Redis will need to enter into a commercial agreement with Redis. The first company to do so is Microsoft.
