System resiliency is similar to high availability in that it relates to systems being available when needed. Solutions architects build resiliency into systems using several different methodologies. Interviewers at Amazon will be very interested in your ability to do this since organizations lose money when their IT systems are down, and their employees can't do their jobs. It would be best to have a portfolio of solutions to design system resiliency and high availability.

William Swansen

"A system is considered resilient if it can continue to function even though other parts of the IT infrastructure have failed or are no longer available. This is especially important in mission-critical systems, which perform functions important to the operations of the organization. Some of the methodologies I would use to ensure system resiliency at Amazon include redundancy, backups, isolation, delegation, and containment. Reducing the impact of any system failure and preventing it from spreading to other systems is key to maintaining high availability and keeping Amazon's business processes functioning."
