WHAT IS OPENSEARCH?
03.
“OpenSearch is a community-driven, open source search and analytics suite
derived from Apache 2.0 licensed Elasticsearch 7.10.2 & Kibana 7.10.2. It consists
of a search engine daemon, OpenSearch, and a visualization and user interface,
OpenSearch Dashboards. […] With OpenSearch people benefit from having an
open source product they can use, modify, extend, monetize, and resell how they
want.”

The Elephant in the Room OR


Two sides of the story
© 2021 floragunn GmbH - All Rights Reserved


BACKGROUND
Elastic published portions of their code under ASLv2 since the beginning


OSS project, typical benefits from community contributions


Also offered commercial, paid features


AWS offered a (paid) managed service based on that code


“Amazon Elasticsearch Service” (AESS), launched 2015


Source: https://aws.amazon.com/blogs/aws/new-amazon-elasticsearch-service/


Elastic began offering their own managed service


“Elastic Cloud”, 2015


“Elastic Cloud Enterprise” (ECE), launched 2017

ELASTIC
“So why the change? AWS and Amazon Elasticsearch Service. They have been
doing things that we think are just NOT OK”


Source: https://www.elastic.co/what-is/opensearch


“Our license change is aimed at preventing companies from taking our […]
products and providing them directly as a service without collaborating with us”


Source: https://www.elastic.co/what-is/opensearch


“We think that Amazon’s behavior is inconsistent with the norms and values that
are especially important in the open source ecosystem.”


Source: https://www.elastic.co/what-is/opensearch


“The change from the Apache License to the Elastic License v2 was a response to
the continued non-collaborative engagement AWS pursued with Elasticsearch”


Source: https://www.elastic.co/what-is/opensearch
15.

AWS
“Developers embrace open source software for many reasons, perhaps the most
important being the freedom to use that software where and how they wish.”


Source: https://aws.amazon.com/blogs/opensource/stepping-up-for-a-truly-open-source-elasticsearch/


“[…] we followed the recommended open source development practice of
“upstream first.” All changes to Elasticsearch were sent as upstream pull requests”


Source: https://aws.amazon.com/blogs/opensource/stepping-up-for-a-truly-open-source-elasticsearch/


“[…] to ensure open source versions […] remain available […] AWS will create and
maintain a ALv2-licensed fork of open source Elasticsearch and Kibana”


Source: https://aws.amazon.com/blogs/opensource/stepping-up-for-a-truly-open-source-elasticsearch/


“They believe that restricting their license will lock others out of offering managed
Elasticsearch services, which will let Elastic build a bigger business.”

“[…] if you choose […] FOSS, that means something, and you have the moral
obligation to uphold”


Source: https://drewdevault.com/2021/01/19/Elasticsearch-does-not-belong-to-Elastic.html


“The whole point of open source is that amazon has a right to do this”


Source: https://www.reddit.com/r/programming/comments/l0m56s/amazon_not_ok_why_we_had_to_change_elastic/


“Amazon went too far, and now the pendulum is swinging back.”


Source: https://www.reddit.com/r/programming/comments/l0m56s/amazon_not_ok_why_we_had_to_change_elastic/


“I can't say I morally disagree with this move.”


https://www.reddit.com/r/linux/comments/kxa4ri/elasticsearch_and_kibana_changing_license_from/


“It's corporate vs corporate.”

Do we need to rethink FOSS?
© 2021 floragunn GmbH - All Rights Reserved


“FOSS SPIRIT” - Theory
In essence


Here’s my software, do whatever you want with it


Including: Make money with it (if you find a way)


Would be great if you contribute


The goal


Get developers on board to contribute (mostly for free)


Drive development


Make the project known in the FOSS space


Increase adoption rate (because it’s free)
21.
© 2021 floragunn GmbH - All Rights Reserved


“FOSS SPIRIT” - Practice
Most projects remain “hobby” projects


Never gain enough traction to “take off”


Many projects struggle


“One person projects”, developed by FTEs in their spare time


Lack of funding, lack of developers, lack of time


Successful projects often backed by companies or organizations


Apache Software Foundation, RedHat etc.


Example: hapi.js


https://github.com/hapijs/hapi/issues/4111

MY PERSONAL OPINION
Choose your weapons and license wisely


Fully understand what the license allows and disallows


It’s either FOSS, or it is not


You can’t enjoy the advantages and avoid the disadvantages at the same time


FOSS might not be the best option for your project


Again, understand the advantages and disadvantages of your license choice


Stick to your guns and license


If you have chosen a license, stick with it


What if Lucene would change its license?
25.
© 2021 floragunn GmbH - All Rights Reserved


MY PERSONAL OPINION
Wide adoption often only possible with a permissive license


Apache web server, nginx, mySQL, K8s, Lucene etc.


Managed services explicitely allowed


FOSS is not a business model!


FOSS is a philosophy backed by ethics, norms and values


It’s not a means to generate revenue


Can not be the (only) foundation of a company


no FOSS no Future

Learnings
© 2021 floragunn GmbH - All Rights Reserved


JUST FORKING IS NOT ENOUGH
Forking is easy, developing is challenging, maintaining is hard


It’s an ecosystem, not a single product


Logstash, Beats, Client Libraries etc.


Keeping development over all components aligned is a challenge


Testing / QA is a challenge


Many different setups and usecases


Many different plugins (Alerting, SQL, Security etc.)

COMMUNITY & ENTERPRISE
Community building requires effort, dedication and steadiness


Community support and engagement


Enterprises require trust and stability


Production readiness


Enterprise support including SLAs


Professional services

  • 21. © 2021 floragunn GmbH - All Rights Reserved Do we need to rethink FOSS?
  • 22. © 2021 floragunn GmbH - All Rights Reserved “FOSS SPIRIT” - Theory In essence Here’s my software, do whatever you want with it Including: Make money with it (if you find a way) Would be great if you contribute The goal Get developers on board to contribute (mostly for free) Drive development Make the project known in the FOSS space Increase adoption rate (because it’s free) 21.
  • 23. © 2021 floragunn GmbH - All Rights Reserved “FOSS SPIRIT” - Practice Most projects remain “hobby” projects Never gain enough traction to “take off” Many projects struggle “One person projects”, developed by FTEs in their spare time Lack of funding, lack of developers, lack of time Successful projects often backed by companies or organizations Apache Software Foundation, RedHat etc. Example: hapi.js https://github.com/hapijs/hapi/issues/4111 22.

  • 25. © 2021 floragunn GmbH - All Rights Reserved MY PERSONAL OPINION Choose your weapons and license wisely Fully understand what the license allows and disallows It’s either FOSS, or it is not You can’t enjoy the advantages and avoid the disadvantages at the same time FOSS might not be the best option for your project Again, understand the advantages and disadvantages of your license choice Stick to your guns and license If you have chosen a license, stick with it What if Lucene would change its license? 25.
  • 26. © 2021 floragunn GmbH - All Rights Reserved MY PERSONAL OPINION Wide adoption often only possible with a permissive license Apache web server, nginx, mySQL, K8s, Lucene etc. Managed services explicitely allowed FOSS is not a business model! FOSS is a philosophy backed by ethics, norms and values It’s not a means to generate revenue Can not be the (only) foundation of a company no FOSS no Future 26.
