Resilience: designed to withstand the unexpected A highly-available, or resilient, application is one that continues to function despite expected or unexpected failures of components in the system. If a single instance fails or an entire zone experiences a problem, a resilient application remains fault tolerant-continuing to function and repairing itself automatically if necessary. Because stateful information isn’t stored on any single instance, the loss of an instance-or even an entire zone-should not impact the application’s
