Room For Improvement

Amazon Linux requires improvements in vendor integration, community support, GUI, documentation, flexibility, and package management for enhanced usability.
Kali Linux users seek better automation, UI, security, and support, with improved installation, hardware detection, and beginner-friendly resources.
Documentation explaining the differences between Ubuntu and Amazon Linux would be valuable.
full stack developer at 71Lbs
Since we are working in a real-time manner and need to scale things immediately, the time it takes to boot an instance and then deploy things is preventing me from giving it a perfect rating.
Level 2 Software Engineer at a computer software company with 201-500 employees
My advice for others looking into using Amazon Linux is to make sure the command line is easy and that Amazon Linux has more performance than other Linux environments and is more secure than other Linux environments as well.
DevOps Engineer at Wissen infotech
If real-time customized port scanning can be added, for example, instead of a default port such as 8080 or 443, if we can use a customized port such as 9876, that capability would be great.
Senior Technical Manager at a tech vendor with 10,001+ employees
I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
If there were video courses attached to how to safely use it, especially for absolute beginners with no previous experience using Linux operating systems, I think that could be very useful.
Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
 

Setup Cost

Enterprise buyers favor Amazon Linux for its cost efficiency, free-tier usage, and reduced expenses with Graviton instances.
Kali Linux is a cost-effective, open-source solution for enterprises seeking a comprehensive operating system with no licensing costs.
With Amazon Linux itself, there is no cost associated with using it, so I would say it is very good from a pricing perspective.
Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
I am paying around $300 to $400 per month because I use many services.
Software Engineer at a tech services company with 501-1,000 employees

Valuable Features

Amazon Linux excels in AWS integration, security, and performance, featuring fast boot, auto-scaling, and efficient resource management.
Kali Linux is favored for its pre-installed security tools, user-friendly design, and customizable features for efficient cybersecurity tasks.
Amazon Linux handles this automatically. It is optimized for EC2, AWS hardware and software, mostly secure and stable, and there is no additional cost.
Senior AWS Consultant at Quantum Integrators
In terms of service security, there are many constraint security protocols and policies that help me create our own networks, security groups, and inline policies.
Software Engineer at a tech services company with 501-1,000 employees
Amazon Linux's security updates have been helpful in general because I have had to be more specific in using the Identity Access Management (IAM) service so that we can have role-based permissions in preference to just keeping it open.
Independent Contractor at a computer software company with 1,001-5,000 employees
Kali Linux has positively impacted my organization by improving efficiency in penetration testing; its open-source nature permits extensive customization and inclusion of numerous comprehensive pre-installed tools, contributing to a secure network environment with effective monitoring of network applications.
SWE-1 at a tech vendor with 10,001+ employees
A unique and really helpful feature of Kali Linux, compared to other operating systems, is that many of the offensive security tools are already pre-configured and pre-installed.

Featured Reviews

SAURAB K GANGURDE - PeerSpot reviewer
Senior AWS Consultant at Quantum Integrators
“Amazon Linux delivers automated security updates— including live kernel patching in AL2023—ensuring protected workloads with minimal manual effort and zero-downtime patching.”
One improvement for Amazon Linux would be stronger support for running it outside AWS. Although Amazon provides local VM images for VirtualBox and VMware, they are intended mainly for development and testing. Unlike Ubuntu, Debian, or Red Hat, Amazon Linux is not designed or fully supported as a production OS in on-prem or hybrid environments. Expanding official support outside AWS would offer more flexibility for teams that maintain mixed infrastructure. Another area for improvement is the community ecosystem. Compared to Ubuntu or Red Hat, Amazon Linux has a smaller community and fewer third-party resources or tutorials. A larger ecosystem would make troubleshooting and adoption easier. Finally, improving backward compatibility between Amazon Linux 2 and Amazon Linux 2023—especially around package management (DNF vs yum) and updated toolchains—would simplify upgrades for teams managing large fleets.
Ciyagi Ciyagi - PeerSpot reviewer
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
