Amazon Linux vs Red Hat Enterprise Linux: What are the differences?

Introduction:

Amazon Linux and Red Hat Enterprise Linux (RHEL) are two popular operating systems used by businesses and individuals. Both are based on the Linux kernel but have some key differences in terms of features and support. In this markdown, we will discuss the main differences between Amazon Linux and Red Hat Enterprise Linux.

1. Package Manager: One of the major differences between Amazon Linux and RHEL is their package managers. Amazon Linux uses the yum package manager, which is similar to RHEL's package manager, while RHEL uses the Red Hat package manager (RPM). However, Amazon Linux 2, the latest version, introduces the dnf package manager, which is a faster and improved version of yum.

2. Support Model: Another key difference is their support models. Red Hat Enterprise Linux is known for its long-term support offered by Red Hat, which includes regular security updates and bug fixes. In contrast, Amazon Linux is primarily supported by Amazon Web Services (AWS) and is more focused on providing support for running applications and services on the AWS platform.

3. Default Software Versions: In terms of default software versions, Amazon Linux and RHEL also differ. Amazon Linux is designed to align with the AWS platform and includes specific versions of software packages that are optimized for use in AWS environments. On the other hand, RHEL typically includes more up-to-date software versions and provides a wider range of software packages in its repositories.

4. Licensing: Both Amazon Linux and RHEL have different licensing models. Amazon Linux is an open-source operating system, with the source code freely available for users to modify and distribute. RHEL, on the other hand, is a commercial distribution with a subscription-based model, which provides customers with access to support and software updates.

5. Security Updates: The frequency of security updates is another key difference between Amazon Linux and RHEL. RHEL frequently releases security updates to address vulnerabilities and ensure the system's security. In contrast, Amazon Linux typically includes the latest security updates as part of its Amazon Machine Images (AMIs), which are pre-configured virtual machines.

6. Pricing: Lastly, there is a difference in pricing between Amazon Linux and RHEL. Amazon Linux is free to use and doesn't require a subscription, making it an attractive option for individuals and small businesses. RHEL, on the other hand, requires a subscription for access to support and software updates, which can be costly, especially for larger enterprises.

In Summary, Amazon Linux and Red Hat Enterprise Linux differ in terms of their package managers, support models, default software versions, licensing, security updates, and pricing.
