The cloud is not just important; it's mission-critical for many companies. More and more IT and business leaders I talk to look at public cloud as a core component of their digital transformation strategies — using it as part of their hybrid cloud or public cloud implementation.

That raises the bar on cloud reliability, as a cloud outage means important services are not available to the business. If this is a business-critical service, the company may not be able to operate while that key service is offline.

Because of the growing importance of the cloud, it’s critical that buyers have visibility into the reliability number for the cloud providers. The challenge is the cloud providers don't disclose the disruptions in a consistent manner. In fact, some are confusing to the point where it’s difficult to glean any kind of meaningful conclusion.

Reported cloud outage times don't always reflect actual downtime

Microsoft Azure and Google Cloud Platform (GCP) both typically provide information on date and time, but only high-level data on the services affected and sparse information on regional impact. The problem with that is it’s difficult to get a sense of overall reliability. For instance, if Azure reports a one-hour outage that impacts five services in three regions, the website might show just a single hour. In actuality, that’s 15 hours of total downtime.
