Gaining Operational Excellence for improved resilience

The Operational Excellence pillar streamlines cloud workload operations through standardized processes, automation, and monitoring. It aims to simplify administration tasks, enhance system availability, improve customer satisfaction with consistent performance, and accelerate innovation through efficient iteration. Key aspects include change management, automated event response, root cause analysis, and continuous learning from operational events.

So how does that relate to reliability? If we look into the key design principles of the operational excellence pillar we can find performing operations with code, making frequent small, implementing reversible changes, refining operation procedures frequently, anticipating failures when they happen, learning from failures, leveraging AWS managed services, and implementing observability for actionable insights.
