(Tip: It's Not About Availability)
In 2014, Multi-Cloud is an integral part of any corporate cloud strategy. The argument we hear most often is that multi-cloud lets your company seamlessly transition from one provider to another provider in case the former goes down.
This is, of course, a huge asset to your business! There is, however, a significant flaw in that reasoning.
Remember Netflix, the company that pioneered cloud-native infrastructure? When did you first hear about them? Maybe in 2012, when they released their famous Asgard tool. Well, at that point, they had been using AWS for two years already.
Nonetheless, it wasn’t until December 2013 that they finally announced that they were capable of doing hot cross-region failovers — the kind where you switch clouds in real-time for disaster recovery. That is three years after they started using AWS — and they’re doing it between AWS regions, not even between different clouds.
There are two important learnings here. First: three years is a long time to see return on your investment. Second: you don’t actually need multi-cloud to do hot failovers (note: us-east and us-west have never gone down simultaneously).
Ultimately, availability just isn’t the most significant driver for multi-cloud. Don’t worry, though! Multi-cloud is still a good idea, but here’s why:
