What is RedHat?

Red Hat is a company that makes a popular version of the Linux operating system, called Red Hat Enterprise Linux (RHEL). It provides the software, updates, and support that businesses use to run servers, cloud services, and other computer systems.

Let's break it down

  • Company: Red Hat is a business that creates and sells software.
  • Linux: An open-source operating system, like the “brain” of a computer, that can be freely used and modified.
  • Enterprise: A version built for large organizations, with extra stability, security, and professional help.
  • RHEL: The specific product name; it’s a packaged set of Linux tools ready for business use.
  • Updates & support: Regular fixes and a help desk that companies can rely on when something goes wrong.

Why does it matter?

Because many critical services-like banking, online shopping, and cloud platforms-run on RHEL, knowing what it is helps you understand the backbone of modern digital infrastructure and why reliable, secure software matters.

Where is it used?

  • Large corporations run RHEL on their data-center servers to host applications and databases.
  • Cloud providers (e.g., AWS, Azure) offer RHEL as a ready-to-use virtual machine for developers.
  • Government agencies use it for secure, audited computing environments.
  • Universities and research labs deploy RHEL for high-performance computing clusters.

Good things about it

  • Strong commercial support and long-term security updates.
  • Certified to work with many hardware vendors and enterprise software.
  • Consistent, stable releases that make planning upgrades easier.
  • Extensive documentation and training resources.
  • Compatibility with other Linux distributions, easing migration.

Not-so-good things

  • Licensing costs can be high for small businesses or hobbyists.
  • The default installation is more heavyweight than some lightweight Linux alternatives.
  • Some newer open-source features may appear later than in community-driven versions.
  • Requires a subscription to get official updates and support, limiting truly free use.
