SECURITY IN A GREY-OUT - READY FOR THE NEXT CLOUD OUTAGE?

摘要

When anyone sputters the words 'cloud outage', the first alarms to hit one's mind are 'Holy Molly', 'downtime', 'customer complaints' and 'how long'-may be, not in that particular order. So when major cloud outages happened this year, we found out how network congestion, domain level controllers, Domain Name System (DNS) connect, faulty database scripts, maintenance misconfigurations and data automation software can play the devil. We also got smarter in the areas of Service Level Agreement (SLA) credits, dependencies of modern computing architectures, details of service-level downtime from cloud providers (specially from Google's GCP), the usefulness of granular-level reporting (like the one shown by AWS) - thanks to these very outages.
