It is the AWS Elasticsearch Service that will be directly impacted. It will be limited to Elasticsearch 7.10.x as a foundation. Unless of course AWS makes available the code that they use to orchestrate and manage that service. Assuming that that code is sufficiently uncoupled from other systems, they could perhaps do exactly that. It would certainly be an entertaining counter-move from AWS.
IMO, the SSPL's cloud provision is a "Japanese No", it is so wide in possible interpretation, that only the Eclipse foundation could actually provide such a service.
Wrong. It only affects code going forward. Elastic can't change the license of existing code.
Horrible service. That’s why it’s ironic that Elastic just shot themselves in the foot with this licensing change. So foolish.
