Elastic has announced that starting with version 7.11, Elasticsearch will be licensed via SSPL, a license introduced by Mongo in 2018, replacing the Apache 2.0 open source business model previously used. This change may impact companies that offer Elasticsearch as a service, requiring them to reassess their business models and adjust accordingly. However, ChaosSearch, which uses Amazon's Open Distro Kibana, is not affected by this licensing change, as it is already licensed under Apache 2.0. The licensing change does not impact ChaosSearch's performance or cost advantages over the Elastic Stack. Overall, the change highlights the evolution of open-source licenses and their potential implications for companies that rely on Elasticsearch in their offerings.
