AWS recently experienced two significant failures: a partial network outage that affected an availability zone's connectivity to the internet, and another gray failure with a severe impact on well-known internet services. These incidents highlight the importance of monitoring key metrics, such as latency and throughput, to detect potential issues before they escalate. The analysis also emphasizes the need for contingency planning, including infrastructure backup strategies and APIs that can handle increased traffic. Additionally, building resilience into infrastructure is crucial, especially when relying on shared cloud services. By learning from these failures, organizations can improve their disaster recovery plans and reduce downtime.
