Last week Elastic Search BV announced that it is changing its licensing strategy for its products and will not release new versions of Elasticsearch and Kibana under the Apache 2.0 license. Instead, new versions will be offered under its own Elastic License (which restricts its use) or the Server Side Public License (which contains requirements that make it unacceptable to many in the open source community). This means that Elasticsearch and Kibana will no longer be open source software.
To ensure that open source versions of both packages remain available and supported, Amazon has announced that it will take steps to create and maintain an open source fork of Elasticsearch and Kibana with an Apache 2.0 license. A fork from the latest Elasticsearch 7.10 codebase, remaining under the old Apache 2.0 license, will be created within a few weeks, after which the fork will continue to develop on its own and be used in future releases
own distribution from Amazon Open Distro for Elasticsearch, and will also be used in the Amazon Elasticsearch Service.
Also about a similar initiative announced Logz.io company.
Elasticsearch is a search engine. Written in Java, based on the Lucene library, official clients are available in Java, .NET (C#), Python, Groovy and a number of other languages.
Developed by Elastic along with related projects - Logstash data collection and analysis engine and Kibana analytics and visualization platform; these three products are designed to be used as an integrated solution called "Elastic Stack".
