Following RedHat’s announcement (December 2020) to drop CentOS for CentOS stream, a lot of discussion has occurred among IT professionals on how to find the best open-source replacement.
The two Operating Systems that dropped in as a replacement for CentOS are AlmaLinux and RockyLinux.
AlmaLinux and RockyLinux on Cloud
Deploying AlmaLinux and RockyLinux on Cloud or Bare-metal servers is free of charge. Both Operating Systems are based on RHEL source code with frequent security updates and large community support.
Whilst there is no Vendor-supplied paid support available, AlmaLinux and RockyLinux received a warm hug by the IT industry especially by those freelancers, hosting providers and IT pros who are looking for a purely free, open-source replacement for CentOS 8.
