What is difference between Basic and Open Source type license ? Why Basic license when Open Source is there ? Can we deploy commercially using open source license ? And will security be free with that starting 7.1.1 even with Open source or with Basic only?
While the code for X-Pack is available in a public repository, we do not claim that it is "Open Source". See Subscriptions about the different features available.
The default distribution of Elasticsearch includes all of X-Pack, but the default license is "basic".
You can activate a free trial of the commercial features via Kibana (Management -> License) or via the API.
The basic license gives you access to many features including some security features like TLS, file based authentication, role based access.
