Architecting cost-effective resilience

While resiliency maximizes system availability, it can also introduce additional infrastructure complexity that impacts costs. The AWS Well-Architected Cost Optimization pillar demonstrates how to build resilient systems while optimizing your AWS spend. By architecting solutions that take advantage of AWS’s global infrastructure and managed services, you can reduce costs through operational excellence while automating resilience capabilities. Using serverless and containers enables inherent resiliency and auto scaling capabilities without overprovisioning. Continually evaluating utilization metrics and right-sizing based on data empowers you to optimize costs for resilient workloads. However, excessive focus on cost optimization can lead to architectural choices that reduce resilience, fault tolerance, and availability. Careful analysis of the tradeoffs between resiliency patterns and cost reduction strategies is required to balance both...
