A Deep Dive into Big Companies' Approach to Automatic OS Updates on Important Servers

In the digital era, companies of all sizes strive to ensure their servers and systems are secure, efficient, and free from vulnerabilities. However, when it comes to implementing automatic OS updates on their important servers, big companies typically adopt a cautious approach. This article explores the common practices and strategies employed by these organizations to manage updates, particularly focusing on critical security updates and cloud migration.

Common Practices for Handling Automatic OS Updates

Critical Security Updates:

Many organizations prioritize the automatic installation of critical security updates. These updates are crucial in mitigating risks and protecting against cyber threats. Companies often employ testing and staging environments to evaluate the compatibility of updates with existing systems and applications before deployment. This step helps prevent service disruptions. Controlled update policies are implemented, scheduling updates during maintenance windows or rolling updates to minimize disruption. Companies may utilize configuration management tools like Ansible, Puppet, or Chef for systematic update management. This allows for automation while maintaining control over the update process. Prior to applying updates, organizations ensure they have robust backup and rollback plans in place. These plans are critical in case an update causes issues that require reverting to a previous state.

The Shift to Cloud Migration and Regular Re-Deployment of OS

As big companies move towards cloud migration and adopt a model of continual deployment, the approach to OS updates has also evolved. Instead of frequently ‘updating’ the OS, they are moving towards a model of re-deploying the OS through tools like Docker. This shift is driven by several key considerations:

The nature of updates often causes breakages, leading to maintenance challenges. The presence of stringent change management policies in most corporations means that server configurations cannot be changed arbitrarily. Critical changes require rigorous testing to confirm there is no impact on service. If any issues arise, the change is typically rolled back or the machine restored to its original state.

Conclusion

While the automatic installation of critical security updates is a priority for big companies, it is often not the case for other types of updates. This approach balances the need for security and efficiency with the imperative to maintain stability and prevent disruptions. As organizations move towards cloud-based services and automated deployment, the way they handle OS updates continues to evolve, reflecting a broader trend towards operational flexibility and resilience.
