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.

Hybrid data platform has delivered reliable transactions and powerful performance for our apps
One of the most important points about PostgreSQL on Ubuntu is that it is free. We do not have to worry about cost per core. It is a fully-featured database that supports a lot of features that modern applications need. In fact, it even supports document-based databases. It is quite a powerful solution. The performance of PostgreSQL on Ubuntu's parallel query executions was very good. That is why we selected the solution. We utilize ACID transactions with PostgreSQL on Ubuntu. ACID transactions impact our data reliability in our work significantly. Reliability is very important and ACID helps us reach that goal. Regarding isolation specifically, our application did not require any specific isolation of transactions, but overall, ACID is still very important.

"The tools available in Kali Linux are incredibly effective for conducting security assessments."
"In general, Kali Linux is used for hosting applications, developing new applications, and operating systems. It's also used in containers and nodes.

"The best advantage of PostgreSQL on Ubuntu is its ability to fulfill all our requirements as an RDBMS; we frequently use various database-related operations such as storing, retrieving, and utilizing views and triggers, and its concurrency and connection handling are very efficient, especially since we have around 1,000 users."
"We have worked with various databases including SQL Server and MySQL, but I found PostgreSQL on Ubuntu to be the most cost-effective and most performance-friendly solution."
"PostgreSQL on Ubuntu has positively impacted my organization by being very reliable; it has solid recovery and the risk of data loss is very low, making it very robust and ideal for production projects."
 

Cons

"While Kali Linux has gotten better over the past years, it could be improved if it was bundled in a CLI-only pack."
"Some tools in Kali Linux lack documentation and details on how to use them, which is one area where it can be improved."
"I think Kali Linux can be improved because it is not a beginner-friendly operating system."
"From an improvement perspective, it should be made possible for users to learn about the product easily."
"However, something about it might be improved, maybe the overall smoothness of it, because there are sometimes when I try to run a lot of applications, it tries to hang up on me."
"The installation process of Kali Linux can be slow, particularly when installing and upgrading packages within virtualized environments."
"The tool is slightly difficult to learn."
"The only real limitation I can see with Kali Linux is the steep learning curve of using it."
"PostgreSQL on Ubuntu can be improved because it is a bit slower than other solutions I have used."

Pricing and Cost Advice

"Kali Linux is a free product, and you don't have to pay for a license."
"The price is good because Kali Linux already provides a good bundle of tools."
"There is no need to make any payments towards the licensing costs since it is a solution that is available for free."
"I have used the free version."
"The tool is open-source."
"Kali Linux offers a perpetual license, meaning you pay for it once and can use it. While free versions of Linux are available, Kali Linux, being an enterprise edition, usually comes with a perpetual license. I rate its pricing a five out of ten."
"I use it free of charge."
"Kali Linux is open source."
