No-cost RHEL for small production workloads
You might have heard the rumor that Redhat had basically killed the Centos product line as we knew it in last December: https://blog.centos.org/2020/12/future-is-centos-stream/
This caused a massive disturbance in the Centos users’ community, see https://arstechnica.com/gadgets/2020/12/centos-shifts-from-red-hat-unbranded-to-red-hat-beta/ for more on the topic.
So Redhat in a response has announced they will provide “no-cost” access to Redhat for “small production workloads” up to 16 servers, and for “customer development teams” as well.
It’s also worth to read a related Ars Technica article from Jim Salter: https://arstechnica.com/gadgets/2021/01/centos-is-gone-but-rhel-is-now-free-for-up-to-16-production-servers/
