Recently, cyber-security firm CloudStrike faced a significant setback when a routine update led to widespread system failures for many Microsoft Windows users. Intended to boost performance and security, the update instead caused disruptions for many businesses dependent on their services. This incident serves as a potent reminder of the necessity for meticulous testing and well-planned rollouts in software development. Indeed, it’s about taking proactive steps to ensure updates are seamless and do not disrupt operations.
Testing Environments
Proper testing environments are crucial in preventing update failures. These environments mimic real-world conditions and allow for comprehensive testing before deployment. At Objective, we create a testing environment for each of our software development projects. We require that our clients access the test site and provide feedback on changes before they are deployed to the live site. Benefits of a robust testing strategy include:
- Identifying and fixing problems before they affect users
- Ensuring that updates meet their intended goals
- Minimising disruptions during the deployment phase
Staged Roll-Outs
A staged roll-out is a method where updates are gradually released to a subset of users before a full deployment. This approach helps identify and address potential issues on a smaller scale, reducing the risk of widespread problems. By carefully monitoring the performance and impact of the update during these initial stages, adjustments can be made before a full-scale release. Best practices include:
- Releasing updates to a small group of users first where possible
- Tracking performance metrics and user feedback
- Making necessary adjustments based on the collected data quickly
Some web applications may not support deploying updates to specific user groups. For projects where selective deployment isn’t feasible, a rigorous testing environment is vital. Start by thoroughly testing the update in a development or staging environment to catch and resolve potential issues before any broader deployment.
Monitor performance metrics and user feedback closely once the update is live, even if it’s for all users. This allows you to quickly identify and address any issues that arise. Make adjustments based on this feedback to enhance the update and mitigate any negative impact.
Practical Steps for Businesses
To avoid update failures similar to CloudStrike’s, consider the following actionable steps:
- Set aside time for thorough testing
- Implement staged roll-outs where possible
- Gather and act on feedback during and after updates
- Have a plan in place to quickly revert updates if issues arise
How the CloudStrike / Microsoft Security Incident highlights the importance of a structured approach to software updates
A robust testing environment and staged roll-outs can significantly reduce the risk of disruptions and ensure smoother updates.
