In September, non-profit IT association CompTIA reported that greater than six in 10 cloud users have “made secondary shifts of infrastructure or applications following their original transition to the cloud.” This means these organisations are using a “multi-cloud” approach — leveraging at least two cloud services to reduce risk of data loss and performance issues. The idea is that organisations can choose the right cloud type and service to balance the varying needs of their systems and data. Here are some of the benefits of considering multi-cloud for your organisation.
Some notable cloud service provider failures in recent years have prompted many businesses to take a good, long look at the safety of their systems. A multi-cloud approach lets you put your servers in different data centres managed by different providers, so that if one provider fails, it doesn’t cause a catastrophic loss of service to your business. Distributing your servers across providers also reduces the impact of potential electricity and networking provider outages. You have the mobility to take your cloud servers from one provider and move them to another to protect your business.
There’s a standard rule to follow when pondering cloud services for business: What’s secure might not be the most cost-effective and what’s cost-effective might not be the most secure. Organisations might initially be tempted to drop everything in a seemingly fail-proof private cloud — but that can be mighty expensive. Yet there are data and workloads that absolutely cannot legally or compliantly go into the public cloud.
Having a multi-cloud strategy enables organisations to maximise costs, performance and security by switching between providers and cloud types or even moving applications or infrastructure back into their own data centres for security reasons. Organisations have become more opportunistic in how they evaluate cloud services, always looking for a better price, customer service and features, points out the CompTIA research. This approach also prevents vendor lock-in.
Appropriate application fit
Some tasks perform better on certain clouds. If your organisation has a need to deliver elastic services to a wider number of users over the internet, a public cloud option will work best. But even then, each public cloud provider offers different features. A Gigaom article from last year points out that organisations running certain frameworks for data-intensive-real-time apps might suffer from performance issues on more generic public clouds when they try to scale. A multi-cloud approach lets you move these applications to a different public cloud that might be better equipped to handle the latency of this intensive workload.
A multi-cloud approach may be where the future is headed, but it still takes strategic planning and a migration strategy. Enlisting the help of an IT and cloud service integrator can provide a whole-picture approach that takes into account system and application needs, compliance issues and budget to find the right mix of clouds for your business.
