Excerpts from what Red Hat just announced today :
While CentOS Linux provided a no-cost Linux distribution, no-cost RHEL also exists today through the Red Hat Developer program.
The program’s terms formerly limited its use to single-machine developers. We recognized this was a challenging limitation.
We’re addressing this by expanding the terms of the Red Hat Developer program so that the Individual Developer subscription for RHEL can be
used in production for up to 16 systems. That’s exactly what it sounds like: for small production use cases, this is no-cost, self-supported RHEL.
You need only to sign in with a free Red Hat account (or via single sign-on through GitHub, Twitter, Facebook, and other accounts) to download
RHEL and receive updates. Nothing else is required. This isn’t a sales program and no sales representative will follow up. An option will exist within
the subscription to easily upgrade to full support, but that’s up to you.
We recognized a challenge of the developer program was limiting it to an individual developer. We’re now expanding the Red Hat Developer
program to make it easier for a customer’s development teams to join the program and take advantage of its benefits. These development
teams can now be added to this program at no additional cost via the customer’s existing subscription, helping to make RHEL more accessible
as a development platform for the entire organization.
The updated Individual Developer subscription for RHEL will be available no later than February 1, 2021.
We know that these programs don’t address every CentOS Linux use case, so we aren’t done delivering more ways to get RHEL easily.
We’re working on a variety of additional programs for other use cases, and plan to provide another update in mid-February.
