All you need to know about Multi-Cloud

UKCloud is the leading multi-cloud provider in the UK. Hence, we’re often asked what is multi-cloud, and how is it different from public cloud, private cloud, hybrid cloud and distributed cloud?

Whereas public cloud and private cloud are deployment types defined by NIST (the US-based National Institute of Standards and Technology), terms like multi-cloud and distributed cloud recognise that the market has evolved and traditional definitions have become blurred.

What is multi-cloud?

We think of multi-cloud as more of a philosophy than a thing. Multi-cloud is about exploiting the unique capabilities of different clouds, rather than going ‘all in’ with a single cloud.

Multi-cloud versus hybrid cloud

Hybrid cloud refers to a single solution which spans two different cloud deployment types (as defined by NIST). This is commonly where an on-premises private cloud environment (running a secure database) is connected to a public cloud environment (running a scalable front-end).

Multi-cloud is where two or more clouds of any deployment type and any service model are used for different solutions. For example, one public cloud might be used for data analytics, another public cloud might be used for messaging and collaboration, and a private cloud might be used for traditional line of business applications.  In that sense, hybrid cloud is a subset of multi-cloud.

UKCloud provide both hybrid cloud and multi-cloud solutions.

Multi-cloud versus distributed cloud

Distributed cloud is a relatively new category. It refers to public cloud technology that was originally only available from datacentres owned and operated by the public cloud provider. This public cloud technology can now be deployed in third-party locations – such as internal datacentres or branch offices.  Microsoft was the first to deliver this capability through Azure Stack. Now both AWS (Outposts) and Google (Anthos) have followed suit.

UKCloud has long provided the option for customers to have a dedicated instance of UKCloud’s multi-cloud platform in Crown Hosting or on-premises – distributed cloud before it was called distributed cloud.

Multi-cloud and policy

The UK Government announced its Cloud First policy in 2013. This was followed by similar policies across Healthcare, Policing, Defence and Local Authorities. But typically, the policy speaks of ‘public cloud first’ and reference to multi-cloud is implicit rather than explicit. For example, the Technology Code of Practice specifically talks of a preference for open-source over proprietary technology, and to ensure the use of open standards and interoperability between different solutions.

In our State of Cloud Adoption survey, 40.1% cited lack of clear policy/strategy as a major inhibitor to cloud, 85.5% stated that they would prefer a multi-cloud vendor, and less than 1/5 (19.4)% said they’d only use a single public cloud. Hence, the reality is that policy needs to be refreshed and updated to reflect the need for organisations to use a combination of cloud deployment types (public, private, etc) and cloud service models (IaaS, PaaS, SaaS, etc).

Why do organisations want multi-cloud?

We surveyed more that 300 IT professionals and business leaders across UK public sector and the results were emphatic:

Webinar: ‘The current state of cloud adoption in the UK public sector‘, with Leighton James (UKCloud) and Louise Fellows (VMware)

Webinar: ‘Budgeting and affordability of cloud,’ with Gerry Cantwell (UKCloudX)

Webinar: ‘Managing the commercial risks of cloud,’ with Nicky Stewart (UKCloud), Henry Rex (Tech UK), and Sue Daley (Tech UK)

What are others saying about multi-cloud?

As more and more organisations shift to cloud it is becoming obvious that there is a need for more than one cloud. This is creating a market for technologies and products that help organisations manage multiple clouds. And it means industry analysts and journalists are increasingly addressing it. Here are some highlights:

Analysts

Gartner has published research on multi-cloud and has reflected on the key reasons that organisations have taken that path.

“In a recent Gartner survey of public cloud users, 81% of respondents said they are working with two or more providers… Most organizations adopt a multicloud strategy out of a desire to avoid vendor lock-in or to take advantage of best-of-breed solutions.  We expect that most large organizations will continue to willfully pursue this approach.”

IDC has written a blog on multi-cloud that observes,

“Today, everyone and their dog is using multiple cloud services in Europe. Think about a company (ANY company) you know, that has no productivity suites or HR capabilities delivered in SaaS mode, no virtualized resources on-premise, and no dedicated capacity at an external managed service provider. Exactly — there aren’t any companies like that.”

Cloud Industry Forum has identified five reasons for multi-cloud and said,

“For progressive organizations that want to fly cloud-ward without placing all their eggs in the same basket, they can do just that: leverage a multi-cloud environment. Multi-cloud architecture empowers organizations to distribute their workloads across multiple cloud environments so they can get the biggest bang for their buck while mitigating risks associated with individual cloud environments. This value proposition alone justifies widespread growth and adoption of multi-cloud infrastructure solutions in the future.”

Journalists

Computer Business Review has written about cloud monogamy:

“I often attend Re:Invent conferences, where Amazon has made it a habit to wow its users with a plethora of new services. At the same time, the term “multi-cloud” is understandably absent from their vocabulary. In stark contrast to AWS, challengers like Google are trying to win enterprises’ affection by investing in open cloud standards that encourage a multi-cloud strategy. The best example of this is Kubernetes, Google’s open source container management tool, which is becoming a de-facto standard for workloads that run in multi-cloud environments.”

Forbes has said:

“With cloud infrastructure evolving at such a rapid pace, it becomes more and more difficult to simply migrate from old to new. Multicloud is now mostly a reality forced on organizations due to the rapid growth of infrastructure — a single cloud approach is both unrealistic and naive.”

Vendors

Cisco:

“Customers are moving beyond thinking about what multicloud is, when it’s coming (it’s already here) or why it’s accelerating. At this point, we are in a new phase, where customers need to know how to navigate the complexity and power their next wave of multicloud initiatives. Since introducing the Cisco Multicloud Portfolio, we’ve seen many customers use it to guide their investments. While every customer is unique and has different paths to cloud adoption, we’ve seen common consumption-related use cases emerge with large and small organizations.”

Red Hat:

“Multicloud helps enterprises avoid the pitfalls of single-vendor reliance. Spreading workloads across multiple cloud vendors gives enterprises flexibility to use (or stop using) a cloud whenever they want. There’s nothing evil about having multiple clouds—in fact, it’s a good thing. And open source software magnifies that good. Our open source technologies bring a consistent foundation to any cloud deployment: public, private, hybrid, or multi.”

Ultimately, multi-cloud is more complex than single-cloud. Which is why our multi-cloud platform simplifies this complexity and make it much easier for organisations to tap into multiple cloud technologies without having to worry about the underlying complexity.
