DevOps at Chill Flow
You need some type of operating system and a container engine, and these two are best in class.
Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
There is a pipeline for it, and the time saving occurs because whenever a developer pushes anything, that goes into the Docker container and builds it.
Senior DevOps engineer at Elevenxcapital
Integrating Kali Linux with DevOps tools has resulted in reduced operational costs due to automated test cases, making it a worthwhile investment with significant returns by decreasing the attack surface area and the frequency of attack incidents.
SWE-1 at a tech vendor with 10,001+ employees
If we had installed it on-premises or through other means, it would have incurred significant money and effort to create the VMs, deploy it on machines, and then delete and format it after use.
Cloud Security Architect at a tech services company with 10,001+ employees
I have saved time by avoiding the lag I sometimes face on the TryHackMe in-built machine, and I have learned more efficiently.

Scalability Issues

Sentiment score
6.0
Docker on Ubuntu provides scalability and integration for organizations but may require Kubernetes for complex applications, influencing scalability.
Sentiment score
7.5
Users find Kali Linux scalable and flexible, supporting diverse platforms, ideal for penetration testing and educational purposes.
In some cases, Docker on Ubuntu is not enough for all the complexity of the applications, and I have to go to the next level with Kubernetes.
Founder at Asynka
Ubuntu is very stable as an operating system, and Docker scales well when used properly across projects and environments.
DevOps at Chill Flow
Using Docker on Ubuntu together is a common configuration, and you can deploy it directly on server hardware using virtual machines or in the cloud, scaling however you wish.
Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
You can use it on cloud, VPS, and on-premises.
Security Researcher at a consultancy with 10,001+ employees
I would describe Kali Linux's scalability as very scalable because I can deploy it on a range of different machines, whether that is my laptop or using maybe Raspberry Pi or Android.
Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
Regarding the scalability of Kali Linux for my work and projects, whenever I was conducting brute force attacks and provided more than two or three million lines of payload, the system would freeze.
Product security engineer at a tech vendor with 10,001+ employees
 

Stability Issues

Sentiment score
8.0
Docker on Ubuntu is described as stable and reliable, with seamless integration and minimal stability or security issues.
Sentiment score
8.0
Kali Linux is praised for stability and dependability, recommended for virtualization, with occasional issues resolved using older versions.
Docker on Ubuntu is very stable.
Software Engineer at Bounteous
Docker is continually optimized by the Docker company, and Ubuntu is also continually optimized.

Kali Linux is very stable for my needs.
Consultant at Cognizant
 

Room For Improvement

Docker on Ubuntu needs UI improvements, simpler networking, better documentation, and cost-effective solutions for enhanced user experience.
Kali Linux users seek better automation, UI, security, and support, with improved installation, hardware detection, and beginner-friendly resources.
Code sharing ability exists in GitHub and other tools, but in Docker on Ubuntu, other users we are sharing with do not have options like edit and update the code.
Software Engineer at Bounteous
While Docker itself has no cost, the Docker repository and Docker Hub could improve their pricing, especially for startup companies.
Chief Technology Officer at ML Cloud LLC
It is completely complex to understand the networking in Docker on Ubuntu and Kubernetes clusters, as well as the ephemeral nature of the network and storage.
Founder at Asynka
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

Kali Linux is a cost-effective, open-source solution for enterprises seeking a comprehensive operating system with no licensing costs.
I find the pricing for Docker on Ubuntu is not expensive because basically, it is zero.
Founder at Asynka
My experience with pricing, setup cost, and licensing for Docker on Ubuntu is that it was free to use.
Automations Engineer at Ad Up
I do not have a problem with the pricing for Docker on Ubuntu because I do not pay for that; my boss does.
DevOps at Chill Flow
Kali Linux is free software, an operating system that's available to download without any cost or licensing fees.
Associate Consultant at a consultancy with 10,001+ employees
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

Featured Reviews

Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees
Built a reliable cloud foundation that has supported flexible web applications and smooth scaling
Docker on Ubuntu can be improved because Ubuntu is not minimalist at all; it comes with a lot of software by default. This has led some individuals, including myself, to try using Alpine, which is more lightweight, allowing the container to run on a more lightweight operating system that potentially uses fewer resources and reduces costs. If Ubuntu were a little more minimalist, that would be good, but it's not really aiming for that since it intends to be the baseline. Also, Ubuntu moves very fast, possibly faster than other operating systems like Debian, which could demand operational heavy upgrades to major versions every couple of years if there are many applications running.

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.
