Best Operating Systems for DigitalOcean

Fedora CoreOS is a minimal operating system that updates automatically and is designed for securely running containerized workloads at scale. It is accessible on various platforms, with more options anticipated in the near future. There are three distinct update streams for Fedora CoreOS (FCOS): stable, testing, and next. Typically, it is advisable to utilize the stable stream, but running some machines on the testing and next streams is encouraged to contribute feedback. When automating the installation of Fedora CoreOS, you will need to engage with stream metadata. Although Fedora CoreOS performs automatic in-place updates, it is a best practice to provision new machines using the latest available images. Notably, Fedora CoreOS does not provide a separate installation disk; instead, each instance is created from a general disk image that is tailored during the first boot using Ignition. Everything offered within this operating system is open source and free software, meaning not only can you use it without charge, but you also have the freedom to share, modify, and remix it according to your needs. This flexibility makes Fedora CoreOS an appealing option for developers and organizations looking for a robust and adaptable solution.

The advent of container-based infrastructure represented a significant transformation in technology. A Linux distribution specifically optimized for containers serves as the ideal groundwork for a cloud-native setup. This streamlined operating system image consists solely of the essential tools needed for container execution. By omitting a package manager, it prevents any potential for configuration drift. The use of an immutable filesystem for the OS effectively mitigates a range of security vulnerabilities. Additionally, automated atomic updates ensure that you consistently receive the most current security patches and open-source technology advancements. Flatcar Container Linux is purpose-built from the ground up to support container workloads effectively. It fully embraces the container philosophy by incorporating only the necessary components for running containers. In a world of immutable infrastructure, it is crucial to have an equally immutable Linux operating system. With Flatcar Container Linux, your focus shifts from configuration management to effectively overseeing your infrastructure, allowing for a more efficient and secure operational environment. Embracing this approach revolutionizes how organizations manage their cloud-native applications and services.
