Introduction: What Exactly is Cloud Native?
Ah, cloud native. The term that’s as ubiquitous in IT boardrooms as stale coffee and “quick” catch-ups. When dissecting its true meaning, one needn’t look further than the venerable CNCF definition:
Cloud native technologies… enable organizations to build and run scalable applications in modern and dynamic environments such as public, private, and hybrid clouds, while leveraging cloud computing benefits to their fullest. Designed from the ground up to exploit the capabilities of cloud computing, containers, service meshes, microservices, and immutable infrastructure exemplify this approach.
Or, in plain English: It’s all about using the cloud as the cloud ought to be used – agile, scalable, resilient, and full of shiny buzzwords.
CNCF goes on to add:
These technologies enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil. Translation: Fast-moving, high-impact, headache-minimizing systems for organizations that actually understand what they’re doing.
So, How’s the Term Actually Used?
Well, here’s where things get messy. In many a meeting room, cloud native is less about architecture and more about politics. You’ll hear phrases like, “That sounds great, but are we sure it’s cloud native?” – often uttered with an air of faux-concern by someone who’s just discovered the term last week.
In these cases, cloud native becomes a codeword for “Will this work on-premise?” or “How do we dodge vendor lock-in?” – a laughable irony considering most organizations are already ensnared in vendor ecosystems tighter than a bad Christmas jumper. Think SAP, Entra ID on Azure, or ServiceNow – all quite essential, all very sticky.
Worse, some treat cloud native as a private cloud rallying cry. Spoiler alert: cloud native isn’t about where your apps live; it’s about how they’re designed.
Can You Be Cloud Native on a Single Hyperscaler?
The short answer? Yes, absolutely.
Being cloud native is about adopting the principles of cloud computing—agility, resilience, scalability—not about being multicloud. While a multicloud strategy offers flexibility, it’s entirely possible to leverage a single hyperscaler, like Azure, and still build cloud native applications.
Azure offers a robust ecosystem, including Kubernetes, serverless options like Azure Functions, and advanced monitoring tools, all of which align beautifully with cloud native practices. You’re still embracing the essence of cloud native if you design systems that are loosely coupled, highly automated, and capable of scaling rapidly—even if they’re tied to one provider.
Vendor lock-in only becomes a concern if your architecture is overly dependent on proprietary services without a plan for migration. But with the right design, you can enjoy the full benefits of cloud native without sacrificing portability.
The Open-Source Private Cloud Revolution
Now, here’s where things get exciting: open-source private clouds have finally stepped up their game. Once the underdog in the cloud world, these platforms now offer robust technology stacks that fully align with cloud native principles.
With projects like Kubernetes, OpenStack, and tools from the CNCF ecosystem, private clouds can now deliver the scalability, automation, and resilience that were once the exclusive domain of hyperscalers.
What does this mean? You can have your cake and eat it too: the agility of cloud native applications combined with the control and customizability of on-premises infrastructure. It’s no longer an either-or scenario. Organizations now have the tools to build truly cloud native systems, whether their workloads sit in a hyperscaler’s data centre or their own.
This shift is empowering businesses to embrace cloud native principles without surrendering to vendor lock-in or sacrificing regulatory and security requirements tied to on-premises solutions.
The Great Hyperscaler Migration Myth
Another delightful misconception is the belief that cloud native apps are a kind of magic suitcase – effortlessly migrating between Azure, AWS, and the like. Sadly, that’s as realistic as teleporting your office to the Bahamas.
Yes, cloud native apps are more portable than their clunky monolithic cousins. But moving between hyperscalers still requires effort – albeit less effort, and with fewer catastrophic surprises. Think of it like moving house: easier if you’ve packed well, but still a bit of a faff.
Conclusion
Cloud native isn’t a silver bullet, nor is it a moral litmus test for public versus private clouds or vendor allegiance. It is a smarter way to design and build applications, letting organizations harness cloud computing’s full potential while making migration far less traumatic.
With the rise of open-source private clouds, the cloud native dream is now within reach for organizations of all sizes and industries. Whether you’re in a hyperscaler or running your own data center, the tools and tech stacks exist to deliver speed, agility, and resilience – without the myths and misuses that so often muddy the waters.
And yes, you can absolutely be cloud native on Azure or any single hyperscaler, provided you embrace the principles and design your applications with the right level of foresight. Cloud native isn’t about where you are; it’s about how you build.
