Kali Linux could improve with a user-friendly GUI, enhanced support, better documentation, AI integration, and optimized VM images.
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.
Senior Data Engineer at a transportation company with 501-1,000 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.

Setup Cost

Amazon Linux offers cost-effective, scalable solutions without licensing fees, making it a budget-friendly choice for enterprises.
Kali Linux is cost-effective and appealing for enterprises with its open-source, free access, and comprehensive tool suite.
With Amazon Linux itself, there is no cost associated with using it, so I would say it is very good from a pricing perspective.
Cloud Ops Lead at a tech vendor with 10,001+ employees
If I am a new AWS customer, the AWS Free Tier typically includes, for the first six months, micro instances such as t2.micro or t3.micro for free.
Software Engineer at INSTITUTE OF AERONAUTICAL ENGINEERING
I only pay for the EC2 instance and any other AWS resources I use, but the operating system itself has no licensing fees, which is a significant advantage over commercial operating systems like Red Hat Enterprise Linux or Windows servers, which incur extra hourly charges.
Student at Unemployed at the moment
I simply create a VM, so there are no costs involved.
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees

Valuable Features

Amazon Linux, optimized for AWS, offers robust security, cost-effectiveness, and seamless integration, enhancing deployment confidence and reducing overhead.
Kali Linux offers pre-installed security tools, user-friendly interface, and customization, ideal for ethical hacking and penetration testing.
Amazon Linux handles this automatically. It is optimized for EC2, AWS hardware and software, mostly secure and stable, and there is no additional cost.
IT Analyst | Aws Cloud Ops | Dev Ops | Fin Ops at Tata Consultancy
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.
Fullstack Developer 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.

Saurab Gnagurde - PeerSpot reviewer
IT Analyst | Aws Cloud Ops | Dev Ops | Fin Ops at Tata Consultancy
“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.
