The Elasticsearch search engine and the Kibana visualization tool will no longer be available as free software under the Apache 2.0 license from the upcoming version 7.11. Elasticsearch BV announced this in a blog post. In future, there will be a choice between the Elastic License already offered and the Server Side Public License (SSPL) used by MongoDB, for example.
Elastic names the reason for the license change – similar to MongoDB – the commercial use by third parties who offer the Elastic Stack as software as a service without giving anything back. Ultimately, this harms the entire user community.
The vast majority of users are not affected by the change.
The areas of application of the Elastic Stack range from logging and monitoring complex environments to complex data analyzes.
