The $100K Friday Night Rollback: Designing Deployments That Make Failure Boring
Transform your Friday deploys from nerve-wracking to routine with effective rollback strategies.
"Make your Friday deploys boring. A solid rollback strategy is your best ally."Back to all posts
Your last Friday deployment just turned into a nightmare. A single line of code triggered a cascading failure, costing your team $100K in customer refunds. You've seen the panic in your team's eyes as they scramble to revert changes under pressure. It's a scenario no engineering leader wants to face, yet it happens all
too often. The stakes are high, and the pressure is relentless. It's time to rethink your deployment strategy and make rollbacks a mundane part of your process, not a frantic last resort.
For engineering leaders, the change failure rate is a north star metric. A high failure rate means wasted time, resources, and, ultimately, money. The average cost of downtime can be staggering, and in our industry, every minute counts. By focusing on lead time and recovery time, you can measure not only how quickly a
change is deployed but also how efficiently you can roll back if something goes wrong. It’s about being prepared, not just reactive. The more seamless your rollback strategies are, the more confidence your team will have when hitting that big red deploy button on Friday.
**Step 1: Establish Clear Rollback Protocols** Before you deploy, ensure your team has a well-documented rollback plan. This should outline steps to revert changes, including the tools and scripts to use. Tools like Terraform or Helm can help manage your infrastructure as code, allowing you to quickly roll back to a
previous state. It’s not just about having a plan; it’s about practicing it. Conduct regular drills to ensure everyone knows their role during a rollback.
**Step 2: Utilize Blue-Green Deployments** Incorporate blue-green deployments to minimize downtime and risk. This approach allows you to have two identical environments: one live (blue) and one ready to go (green). After deploying to green, you can switch traffic to it if everything looks good. If issues arise, switch
Key takeaways
- Always have a rollback plan before deployment.
- Measure your change failure rate to identify issues early.
- Automate your rollback processes for speed and reliability.
Implementation checklist
- Implement blue-green deployments for quick rollback.
- Set up automated monitoring for real-time feedback on deployments.
- Create clear documentation for rollback procedures.
- Conduct regular drills simulating rollbacks to ensure team readiness.
Questions we hear from teams
- What is a rollback strategy?
- A rollback strategy is a plan for reverting changes made during a deployment if something goes wrong, minimizing downtime and impact.
- Why is measuring change failure rate important?
- Measuring change failure rate helps identify issues early, enabling teams to improve their deployment processes and reduce costs.
- How can we automate rollback processes?
- Using tools like Terraform, Helm, or CI/CD pipelines can help automate rollbacks, ensuring speed and reliability during incidents.
