Simulating Kubernetes-workload AZ failures with AWS Fault Injection Simulator

In highly distributed systems, it is crucial to ensure that applications function correctly even during infrastructure failures. One common infrastructure failure scenario is when an entire Availability Zone (AZ) becomes unavailable. Applications are often deployed across multiple AZs to ensure high availability and fault tolerance in cloud environments such as Amazon Web Services (AWS). Kubernetes […]

Perform Chaos Testing on your Amazon Aurora Cluster

“Everything fails all the time” Werner Vogels, AWS CTO In 2010, Netflix introduced a tool called “Chaos Monkey”, that was used for introducing faults in a production environment. Chaos Monkey led to the birth of Chaos engineering where teams test their live applications by purposefully injecting faults. Observations are then used to take corrective action and […]
