In today’s competitive IT Infrastructure market, many businesses are moving towards virtualization or “Cloud Computing.” JeOS, or “Juice,” is a revolutionary concept designed specifically for Virtualization and Cloud Computing. JeOS is a concept wherein standard server software is stripped down to a “bare-bones” state and only the services or features that a company requires are installed and configured. This allows standard servers to be smaller, run faster, and concentrate on a single task, as opposed to being overwhelmed with smaller tasks that may interfere with each other. JeOS systems are also easily replicable and since they install in the same fashion that normal server software does, any differences in system hardware are taken into consideration. This allows a JeOS system to be installed on many different sets of hardware without any changes.
JeOS concepts can also be applied to desktop computing. An entire office computer system can be rebuilt very quickly and installed with a standard set of required software for the users. Rolling back a JeOS system to a default state is also quick and will still contain any customizations included in the JeOS setup. JeOS systems can be set up to automatically install software, configure settings, connect network drives, and even run post-installation scripts.
JeOS has currently only been applied to Linux distributions but may be adopted by other operating systems as well. Some of the most prominent JeOS systems are being developed for: CentOS, Ubuntu, rPath, OpenSUSE, and SUSE Enterprise.
Anyone can build a JeOS system and the following two websites can help you explore JeOS in detail:
- SUSE Studio (http://susestudio.com)
- rPath Builder (https://www.rpath.org/ui/)
Many common server distributions already use the concept of JeOS:
- OpenFiler
- AsteriskNOW
- KnowledgeTree
- rPath Linux
- Phonehome – Open VPN Appliance
- Ubuntu server also distributes a JeOS version
JeOS is a huge step forward in intelligent computing and will continue to develop and become a strong driving force in information technology.
