Last week Microsoft Azure suffered a major outage, disrupting many enterprises worldwide that had shifted their workloads to Microsoft’s public cloud, including companies who have upgraded to Office 365.
The cloud skeptics are already gathering to tell these companies they shouldn’t have moved to the cloud, but ask the IT managers of LAN-based services whether they ever have had unplanned downtime and of course the answer is yes. So what’s the answer to the downtime conundrum?
The simple solution is to treat the cloud with the same level of respect that we’ve been treating our on-premises systems for decades…are your core services, like email, so important that your business cannot do without them?
If the answer to that question is ‘yes’, and it usually is, then you should go for a blended-cloud approach.
Despite the fact that these events will be frustrating and disruptive for Microsoft customers (or Google or any other service for that matter) it’s still no reason to stop plans to move to the cloud, or retreat to the shelter of the LAN. However, this incident should be a trigger for IT teams to check they are being careful about what core cloud service they choose and then how they protect it.
When you move critical services and data, like email, to the cloud, you must also plan for the inevitability that at some point the service will most likely go down – just as you would with business continuity solutions on your own infrastructure if you kept them in-house. With Mimecast services you keep employees’ email up and running, and keep them productive even in the event of an outage.
What happens when the cloud service goes down? Every IT leader should be able to answer that question immediately and show their continuity strategy. A strategy based on planning and technology, not hope.
