You’ve moved data to the cloud. Now it’s time to talk about disaster recovery — how to build a resilient system that can recover from catastrophic failure.
Amazon Web Services, for example, says its S3 service “is designed to deliver flexibility, agility, geo-redundancy, and robust data protection.” To IT, that means the system is fault-tolerant, managing the resiliency needs for you. (“Geo-redundancy” means that, if a center goes down, another center in another part of the country or world will pick up the load. You should never miss a beat.)
If AWS and other public cloud providers include a certain amount of resiliency services, does that mean your data is safe? For the most part, it is. Public cloud providers take great pains to see that data is not lost — ever.
