Amazing Jails **Rating:** 4.5/5.0 stars **Reviewed by:** Sergei G. | System Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** June 27, 2022 **What do you like best about FreeBSD Jails?** Creating isolated secure virtual machines. Network stack virtualization engine. In the case of hacking a virtual system and bringing its functionality out of action, it will not affect other running virtual systems. **What do you dislike about FreeBSD Jails?** It is not possible to use multiple IP addresses for one JAIL. Lack of differentiation of system limits between the parent and guest systems. Difficulties with using direct access to devices. **Recommendations to others considering FreeBSD Jails:** Many system flaws can be fixed using third-party patches. In modern FreeBSD, each virtual machine can be assigned multiple IP addresses. **What problems is FreeBSD Jails solving and how is that benefiting you?** The jail mechanism is used to build administered systems on dedicated servers, when the client is given access only to the jail, and the technical staff - to the master system. ### 2. FreeBSD jails are the original 'container' **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Libraries | Small-Business (50 or fewer emp.) **Reviewed Date:** November 07, 2021 **What do you like best about FreeBSD Jails?** FreeBSD jails pre-date containers like Docker by a long shot and as such, are far more straightforward. The thing I like about them is that they are so simple to set up and are easier to understand when compared to newer technologies such as Docker and Kubernetes. **What do you dislike about FreeBSD Jails?** You will need to be very comfortable with a terminal; there is no GUI interface here like you can get for Docker on Windows. If you are comfortable with the terminal, you will easily be able to use jails - if you are not, then I would suggest trying something else. The thing that tech like Docker do well is defining your software's dependencies and letting the container deal with it for you. This is something jails will not do for you. **What problems is FreeBSD Jails solving and how is that benefiting you?** Using jails allows for true isolation of processes on a machine. This is particularly helpful when you have software components that allow the uploading of content and resources that could potentially harm the OS / Machine. We used it for this purpose as the isolation makes this much more secure. ### 3. Jails Make Your Life Easy **Rating:** 5.0/5.0 stars **Reviewed by:** Kaycie S. | Health & Fitness Coach, Health, Wellness and Fitness, Mid-Market (51-1000 emp.) **Reviewed Date:** June 11, 2018 **What do you like best about FreeBSD Jails?** Jails are simple to deploy, safe, and secure. They are very reliable for spinning up virtualized instances of FreeBSD without much additional overhead. **What do you dislike about FreeBSD Jails?** It's not as easy to use for someone who comes from a graphical operating system background. **Recommendations to others considering FreeBSD Jails:** You should definitely consider FreeBSD Jails if you're looking for a solution that is easy to deploy for your business. I'm able to effectively run several servers without much overhead at all and it's really simple to set up SSH and manage the sites from anywhere. FreeBSD is also known as one of the most stable operating systems out there. Giant corporations like Netflix and Yahoo use FreeBSD for various types of solutions. Best part? It's free and open source. **What problems is FreeBSD Jails solving and how is that benefiting you?** I'm able to spin up dozens of web servers and manage them quickly and easily using FreeBSD as a hypervisor. ## FreeBSD Jails Discussions - [What is FreeBSD Jails used for?](https://www.g2.com/discussions/what-is-freebsd-jails-used-for) - [View FreeBSD Jails pricing details and edition comparison](https://www.g2.com/products/freebsd-jails/reviews?section=pricing&secure%5Bexpires_at%5D=2026-05-29+17%3A44%3A51+-0500&secure%5Bsession_id%5D=907da1cc-3b9b-4e01-a787-0a010ff9116c&secure%5Btoken%5D=2a2548730876bd93c0ffbdd5ea9041545269a7377d235537e8860f159a4fd63b&format=llm_user) ## FreeBSD Jails Features **Application Support** - Deployment - Interface support - Processor support - Application Support **System Capability** - Self Healing High Availability - Orchestration - Scalability **Security** - Automatic Security Updates - Security updates ## Top FreeBSD Jails Alternatives - [Docker](https://www.g2.com/products/docker-inc-docker/reviews) - 4.6/5.0 (287 reviews) - [Ubuntu](https://www.g2.com/products/ubuntu/reviews) - 4.5/5.0 (2,337 reviews) - [Red Hat Enterprise Linux](https://www.g2.com/products/red-hat-enterprise-linux/reviews) - 4.6/5.0 (931 reviews)
