That was the main finding from a survey published last month, as reported by Joe McKendrick at ZDNet earlier this week. The research drew responses from 659 participants, 77 per cent of whom reported that they already have, or are planning to deploy workloads across more than one cloud.
McKendrick suggests that this is evidence of an emerging trend among enterprises to adopt multiple clouds or service providers, implying the caution and established wisdom of “distributing one’s eggs among several baskets” is being exercised.
Understandably, as business begins to entrust more and more of its IT to the cloud — trust is a key word here — those who act as guardians for the uptime and performance of their IT operation need to know that reliability in the cloud isn’t going to be an issue. If you’ve been accustomed to colocation for example — very much a hands-on way of working — it feels like a lot of responsibility to hand over to someone else.
Yes, cloud is inherently resilient…
Certainly, if you procure your computing resources from a single cloud based infrastructure, resilience is improved over an approach where workloads depend on individual servers. In a cloud based environment for example, you’re drawing from a pool of resources, so there is an increased tolerance for hardware failure — a server (or number of servers) can go down, and the load is picked up by others without loss of service. Further, the elements of delivering IT resources are distributed in a cloud environment: storage and processing attributes are drawn from different hardware within the infrastructure, and the focus for a single point of failure is mitigated.
However, for those that want additional reassurance — perhaps where workloads are genuinely critical to the integrity of a business, or where backup and disaster recovery strategies are being considered, a multi-cloud setup makes sense.
All of which leads quite nicely into our own multi-cloud offering: Cloud² — the power of two.
…but multiple clouds take resilience further
Taking our own Cloud² arrangement as an example, we’re able to offer increased resilience through two extra layers of diversity. First up, we’ve introduced geographic diversity: two interconnected clouds, hosted in data centres over seven miles apart from one another. Two data centres owned and operated by different suppliers. And the networks that provide connectivity between these data centres, and out to the wider internet? They’re dual diverse too.
The result is exactly the kind of interconnected, commercial resilience that decision makers are seeking in order to satisfy their uptime requirement: when they migrate workloads and data to the cloud, they’re going to be there when they need them.
