Definition
Just enough operating system (JeOS) is a limited version of an OS (operating system) tailored for a specific application. It includes minimal components needed to support those apps, lowering its general footprint in terms of resource utilization, size, and possible security susceptibilities.
This OS is popular in cloud computing and virtualized environments, where security and efficiency are essential.
JeOS Common Implementations
- Ubuntu JeOS: Ubuntu JeOS has a minimal base setup with the crucial mechanisms needed for virtualized environments.
- SUSE Linux Enterprise JeOS: The SUSE Enterprise Linux Distribution JEOS is common in cloud and virtualization platforms. It is a compact and lightweight version of their enterprise OS, ideal for deploying programs in resource-restricted environments.
- VMware Photon OS: Photon OS by VMware is a lightweight Linux container host designed for VMware platforms. It is a safe, quick, and scalable tool for container and cloud environments, making it a common option for implementing containerized programs.
- Google Cloud’s Container-Optimized Operating System: The OS is designed particularly for the Google Cloud Platform. It is optimized for running Docker containers and has Docker pre-installed. It is a safe and lightweight choice for running containers on Google Cloud.
- Red Hat Enterprise Linux (RHEL) Atomic Host: Red Hat discontinued the Atomic Host by, which was an immutable and lightweight service for executing containerized applications, like JeOS. However, RHEL now integrates these functionalities onto its CoreOS for the same purposes.
- Fedora CoreOS: It is a minimal, container-centric OS that provide secure, consistent, and reliable foundation for containerized environments in large-scale cloud deployments.
- RancherOS: This is also a lightweight Linux distribution that run Docker containers in its only process, making it ideal for containerized systems.
