FreeBSD Jails Description
Many tools have been created to make system administration easier. These tools can improve the way systems are configured, installed, and maintained. Jails are one of the tools that can be used to increase the security of a FreeBSD-based system. Jails have been around since FreeBSD 4.X. They continue to improve in their reliability, security, and usefulness. Jails are based on the chroot(2) concept. This is used to modify the root directory of a group of processes. This creates an environment that is safe and separate from the rest. Jails are a way to improve the traditional chroot environment. Processes are limited in what part of the file system they have access to in a traditional chroot environment. The chrooted processes share the rest of the system resources, users, running processes, as well as the networking subsystem with the processes of both the host system and the chrooted processes.

Sandboxie
Sandboxie, a sandbox-based isolation program for 32- and 64 bit Windows NT-based operating system, is available. Since it became open-source, David Xanatos is developing it. Before that, Sophos developed it. It creates an isolated, sandbox-like operating environment in which applications are able to run or be installed without permanently changing the local or mapped drive. It allows for controlled testing of untrusted programs as well as web surfing. The Open Sourcing Sandboxie is available in two flavors: a classic build with an MFC-based UI, and a plus build that includes new features and a completely new Q't-based UI. The plus branch features are the most important, but can often be used in the classic edition by manually editing sandboxie.ini.

Google Cloud Run
Fully managed compute platform to deploy and scale containerized applications securely and quickly. You can write code in your favorite languages, including Go, Python, Java Ruby, Node.js and other languages. For a simple developer experience, we abstract away all infrastructure management. It is built upon the open standard Knative which allows for portability of your applications. You can write code the way you want by deploying any container that listens to events or requests. You can create applications in your preferred language with your favorite dependencies, tools, and deploy them within seconds. Cloud Run abstracts away all infrastructure management by automatically scaling up and down from zero almost instantaneously--depending on traffic. Cloud Run only charges for the resources you use. Cloud Run makes app development and deployment easier and more efficient. Cloud Run is fully integrated with Cloud Code and Cloud Build, Cloud Monitoring and Cloud Logging to provide a better developer experience.
