Cesium ion SaaS and Cesium ion Self-Hosted utilize containers to provide Cesium ion. Containers are cloud-native, lightweight, and stand-alone software packages that include everything needed to run a piece of software: the code, runtime, system tools, libraries, and settings. This encapsulation ensures that the software runs consistently across various computing environments, from development to testing and production, regardless of the underlying infrastructure. At the heart of any container is the base image, and Cesium has recently updated base images to use the Red Hat Enterprise Linux Universal Base Image as deployed by Iron Bank. Because containers are smaller than virtual machines, it reduces the surface area to patch and update as part of the software stack.
