Will multicloud save us from outages?


I can tell when there is a public cloud outage because my phone blows up. It’s usually reporters who want quotes about the impact on businesses, ways to avoid the impact, and the likelihood that this is a forthcoming trend. What can I say? Everything technical fails from time to time. Public clouds are no different. The objective with technology is to get the number of failures as close to zero as possible. 

With that said, it makes sense to look for solutions that will lower the risk of outages taking down our business for any amount of time. Lately, that means looking at multicloud to mitigate risk. Let’s examine what multicloud means for outages and how that would work.

Multicloud means we leverage two or more brands of public clouds, say AWS and Azure, or Azure and Google, or perhaps even all three. By not putting all our eggs into one public cloud basket, we lower the exposure that our systems could be taken out by a single public cloud outage.

How would this work as an approach to business continuity?

To protect ourselves from the impact of a single public cloud outage, as many are proposing, we need to take an active/active recovery approach. This means we keep the same application and connected data on two different cloud brands. When an outage occurs, you simply fail-over your cloud-based application from the primary cloud provider to a secondary cloud provider and then return to the primary after the outage ends.

A solution some suggest is to move the application and data at the time of the outage to another cloud provider. Funny thing, you can’t move your working copy of the data and current version of the application if they are contained within an inoperable public cloud. So, let’s skip that one.
