Serverless Exit: A Technical Leader's Guide to Transitioning Away from Serverless

Overview This Unkey blog post examines the strategic considerations for technical leaders when deciding to exit serverless architectures. It discusses the signs that indicate a serverless approach may no longer be optimal and provides a step-by-step migration plan that balances performance, cost, and team velocity.

Key Takeaways

• Identify common pain points that signal it may be time to leave serverless (cold starts, vendor lock-in, unpredictable costs).
• Use a cost-benefit analysis framework to compare serverless with alternative compute models.
• Follow a phased migration playbook: audit, prototype, incremental rollout, and full cutover.
• Align stakeholder communication and set realistic timelines to minimize disruption.
