Not that there isn’t already too much in this world, but hey its a cool headline…
Recently there was another short gmail outage. and it sparked the usual outrage over how unreliable cloud computing is and how OMG nobody should use it etc., etc. Of course people wasted more time complaining about the outage that actually experiencing it, but I digress.
There was also recently an internal email outage that affected us here. What’s notable is that there was no outrage. No claims that ‘on premises email is unreliable’ and how everyone should move to the cloud. I’m not saying there should have been outrage, just noting that there wasn’t any that I saw. Every system has outages. Ours here is generally very reliable and I don’t complain when there is a glitch. But then I don’t complain about a minor outage with a cloud service either. Do you? When your internal email is down for an hour, is there outrage?
I’m not our email or high availability expert. I’m “just a country analyst” and dumb user (of course I’ve been called worse). But some digging shows that most enterprises expect an SLA of about 99.5% (maybe even less), which means downtime of about 3.5 hours per month. Can you imagine the blog traffic if gmail were down for 3.5 hours per month? Twitter would croak (oh wait, it already is croaking..).
Typical uptime for cloud email services is in the 99.9% range. Last time i checked, that looked a lot more reliable. Is there a double standard here? Is internal IT cut a lot more slack? Are expectations unrealistic of cloud providers?
