Machine Learning Drives Changing Disaster Recovery At Facebook

Hyperscalers have billions of users who get access to their services for free, but the funny thing is that these users act like they are paying for it and expect for these services to be always available, no excuses. Organizations and consumers also rely on Facebook, Google, Microsoft, Amazon, Alibaba, Baidu, and Tencent for services that they pay for, too, and they reasonably expect that their data will always be immediately accessible and secure, the services always available, their search returns always popping up milliseconds after their queries are entered, and the recommendations that come to them personalized for them. These hyperscalers have built networks of massive datacenters, spanning the globe, to ensure the data and services are close to their customers and that latency doesn't become a problem. Given all this, disaster recovery becomes a critical part of the business. Hyperscale companies need to make sure business can continue as usual even if a datacenter goes down.
