Shay Banon, founder and CEO of Elastic, reported on your blog than the source code of version 7.11 The distributed search and analytics engine currently shipped in Apache 2.0 is cwill switch to a dual licensing system "EOS No Approved Elastic and SSPL".
In the words of Shay Banon, mention whate this license change ensures that the community can access, use, modify, redistribute and collaborate with the code and openly, plus it also prevents the cloud service provider from providing Elasticsearch and Kibana services with no return, "thus protecting our free development distribution Continued investment in open source products."
“We are moving Apache 2.0 licensed source code on Elasticsearch and Kibana to dual license under Server Side Public License (SSPL) and Elastic License, so users can choose which license to order.
The first of these licenses came into force from 2018 and supports the development of open core models (open function core + other proprietary modules) across the entire Elastic stack (Elasticsearch, Kibana, Beats, Logstash).
The model first involves the addition of paid features, for example alarm systems and machine learning building blocks, and then free components were added, including components for monitoring and debugging.
On the side of SSPL, this is a license created by MongoDB to incorporate open source principles while providing protection to public cloud providers who provide open source products as non-refundable services.
SSPL allows free and unrestricted use and modification, the simple requirement is that if you want to provide a product as a service for others, you must also release all modifications and source code from the commercial layer under SSPL.
“In recent years, the market has changed and the community has come to understand that open source companies need to better protect their software to continue innovating and making the necessary investments. As companies continue to transition to SaaS offerings, some cloud service providers have taken open source products and delivered them as a service without reinvesting in the community.
Switching to the dual license strategy with SSPL or Elastic License is a natural step for us after opening our commercial code and creating a free tier, all under the Elastic license, almost three years ago. It is similar to those created by many other open source companies over the years, including MongoDB, which developed SSPL.
Faced with this change, Amazon announced the creation and maintenance of the fork Elasticsearch and Kibana open source
Esto was released in a blog post by Carl Meadows, Senior Manager of Product Management in Amazon's AWS Division, where he also explained his company's position:
“Elastic has announced that it will change its software licensing strategy and will not release new versions of Elasticsearch and Kibana under the Apache license, version 2.0 (ALv2). Instead, new versions of the software will be offered under the Elastic License (which limits its use) or the server-side Public License (which has requirements that make it unacceptable to many members of 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 well supported, including in our own offerings, today we announced that AWS will step up the creation and maintenance of an open source fork under the ALv2 license. 'Elasticsearch and Kibana'.
What does this mean for the Open Distro for Elasticsearch community?
“We released Open Distro for Elasticsearch in 2019 to provide customers and developers with a complete Elasticsearch distribution that offers all the freedoms of ALv2 licensed software. Open Distro for Elasticsearch is a 100% open source distribution that offers features that virtually every Elasticsearch user or developer needs, including support for network encryption and access controls.
