Hybrid Cloud Computing Redefined Around Multicloud, Kubernetes, Anthos, More
Hybrid cloud computing seems to be a less trendy topic these days than it was seven or eight years ago, when hybrid architectures were exploding in popularity. Yet the hybrid cloud ecosystem has changed tremendously in just the past few years; so much so, in fact, that today’s hybrid clouds are fundamentally different from their predecessors. A hybrid cloud created today looks almost nothing like what passed as hybrid cloud for most of the 2010s.

Here’s a look at the new hybrid cloud definition, and why organizations should rethink their hybrid cloud computing strategies.
The First Generation of Hybrid Cloud
Hybrid clouds have been around since the dawn of modern cloud computing in the mid-2000s. Theoretically, they were defined as architectures that used a central management interface to control workloads that ran partly on on-premises infrastructure and partly in a public cloud.
From the start, however, many organizations ignored the “central management interface” part of the hybrid cloud computing definition. They instead assumed that if you used on-premises resources and a public cloud at the same time in some way, you had a hybrid cloud —even if you lacked a centralized way to manage both parts of your hybrid cloud architecture.
For this reason, as a 451 Research analyst explained to one journalist in 2014, “A true hybrid cloud is rare, and only about one in 10 enterprises have it.”
Changing the Hybrid Cloud Definition
Today, however, true hybrid clouds are becoming much less rare. This is thanks to several new trends and technologies that make it much easier to manage workloads seamlessly across on-premises and cloud-based infrastructure.

The multicloud trend is one of a handful of ways the definition of hybrid cloud computing is evolving.
1. Multicloud. One important trend is the explosive popularity of multicloud architectures.
Arguably, hybrid cloud is a form of multicloud. In that sense, the multicloud trend hasn’t encouraged more hybrid cloud adoption; if anything, it has pushed more organizations to use multiple public clouds at the same time, rather than building more hybrid architectures that combine on-premises resources with a single public cloud.
Yet what the multicloud shift has done is to encourage cloud architects and developers to think in more cloud-agnostic terms. To deploy multicloud workloads efficiently, it is important to avoid getting locked in to a specific cloud vendor’s services or tools, so that you can port them from one public cloud to another with ease.
If you design your workloads with this goal in mind, it typically becomes easier to move workloads between on-premises infrastructures and the public cloud, too. Multicloud has made hybrid strategies more practical from this viewpoint.
2. Kubernetes. Another change that has radically changed the hybrid cloud landscape is the soaring popularity of Kubernetes.
You can deploy Kubernetes anywhere — on premises, in the public cloud, or even on a Raspberry Pi, if you really want. It’s by no means a technology specific to hybrid clouds.
However, Kubernetes has made it easier for organizations to implement hybrid cloud architectures. It offers a central platform that can span on-premises and cloud-based infrastructures.
This isn’t a primary use case for most Kubernetes distributions. But it is for some, including Rancher and Anthos. Both use Kubernetes (along with some other tools) to make it …
