Closing the AWS Reliability Gap

Do you know how resilient your AWS deployment is to failure?

Many organizations only find reliability gaps when there’s an incident or outage.

But there’s a better way.

This guide goes over how to approach AWS reliability, use testing and risk monitoring to verify your deployment’s resilience, and automate it so you can stop outages before they happen.

Don’t leave your resilience on AWS up to chance.

  • Organization-wide critical service monitoring, including key dashboards and KPI metrics emails

  • Service ownership and metrics for organizations maintaining a microservices architecture

  • Effective on-call principles for site reliability engineers, including rotation structure, alert threshold maintenance, and escalation practices

  • Chaos Engineering practices to identify random and unpredictable behavior in your system

  • Monitoring and metrics to detect incidents caused by self-healing systems

  • Creating a high-reliability culture by listening to people in your organization

When it comes to reliability, migrating or building on AWS can be a double-edged sword. On the one hand, the automatic scaling, region/zone redundancy, and managed services of AWS can greatly improve the resiliency of your systems. But on the other hand, you have a more complex system, which means more potential points of failure.

This primer on reliability management on AWS goes over:

  • The shared responsibility resilience model
  • How to proactively scan and test for reliability risks
  • How to standardize reliability measurement with scoring
  • How to automate reliability management
