Planned maintenance

Planned maintenance refers to the process of keeping the application and its surrounding ecosystem comprising of platforms, frameworks, software, operating system, and host and guest drivers up to date with the latest stable releases. It is important to patch software's, drivers, and operating systems with the latest updates as it helps in keeping the environment healthy from a security, performance, and future-ready perspective. Not upgrading an environment is not an option and is a fact of life. Even applications should be upgraded with enhanced functionality, bugs, and hotfixes. Every organization plans for environment and application upgrades and typically these involve shutting down and restarting the application and operating system. It might also involve starting of the physical host operating system that in turn will reboot all guest virtual machines running on top of it.
