Under the new license, cloud service providers hosting Redis offerings will no longer be permitted to use the source code of Redis free of charge. For example, cloud service providers will be able to deliver Redis 7.4 only after agreeing to licensing terms with Redis, the maintainers of the Redis code. These agreements will underpin support for existing integrated solutions and provide full access to forthcoming Redis innovations.

So that's why Microsoft created a redis alternative! Really reminiscent of ElasticSearch doing the same because of Amazon and them forking it. I wonder if their fork is still alive.

I completely understand redis and elasticsearch. It's absolutely no surprise when commercial services abuse the spirit of opensource.

Who does this impact

Organizations providing competitive offerings to Redis will no longer be permitted to use new versions of the source code of Redis free of charge under either of the dual licenses. Commercial licensing terms are available and can enable use cases beyond the RSALv2 or SSPLv1 license limitations. If you are building a solution that leverages Redis, but does not specifically compete with Redis itself, there is no impact.
