Cloud opponents (i.e. on-premises advocates) will point to these occurrences and say “I told you so. The cloud just isn’t reliable enough to trust”. Cloud advocates scoff at that notion, trotting out availability numbers of 99.98% to discredit the naysayers. So who’s right?
Well, the truth is that neither claim is right. This topic of cloud system reliability and availability highlights some myths that exist in both the cloud and the on-premises camps.
One of the myths involves on-premises reliability. If asked, many on-premises advocates and users would dogmatically claim that their system is available 100% of the time. Of course, that’s not true, but every time an on-premises system is unavailable, you don’t hear about it in ComputerWorld. On-premises down time is likely comparable to any cloud system when server issues, software and hardware upgrades, electrical, environmental and networking problems, etc., are considered.
The other myth is that if the cloud providers claim to be up 99.98% of the time, then that’s the end-user’s availability. That’s just not true. The actual availability for a cloud end-user depends heavily on the reliability and speed of their own Internet connection and ISP, and not just the reliability of the cloud provider’s data center.
For all intents and purposes, I believe that system availability/reliability is exceptionally high for cloud and for on-premises systems, and to give one or the other an advantage in this regard would be folly.
