Operating systems lifecycle monitoring is a type of IT service that involves monitoring the life cycle of your company’s operating systems. This can include monitoring the operating systems for potential issues or problems, such as security vulnerabilities, compatibility issues, or performance degradation, and proactively addressing these issues before they cause disruptions or downtime. 

Operating systems lifecycle monitoring can also involve tracking the progress of the operating systems through their life cycles, from development and testing to deployment and maintenance, to ensure that they are being managed effectively. 

By monitoring the lifecycle of their operating systems, companies can reduce the likelihood of problems occurring and ensure that their systems are always up to date and running smoothly.
