CLOUD

True hybrid cloud moves toward the mainstream

In the beginning, the only “real” cloud was public cloud.

There were those that thought that it wasn’t a fit for the enterprise, or perhaps would only be used for test/dev environments. And there were plenty of historical failures for solutions before public cloud to bolster these assertions. But today we know that public cloud is a significant driver of innovation and change in the information technology landscape.

In turn, private cloud was derided by the public cloud crowd as nothing more than “legacy mindset” or a desperate attempt by box sellers to stay relevant by co-opting the cloud term. Wikibon put forth the term “True Private Cloud” in 2015 to show that cloud is as much an operational model as it is a technology (and that private cloud needs to be more than “virtualization plus”). Back in the early 2010s, hybrid cloud was often discussed as a “halfway house” on the journey to cloud, or part of a “bimodal” strategy.

For most enterprise companies today, hybrid cloud (having both public and private cloud) and multicloud (having multiple clouds, a superset of hybrid cloud) are just as much a reality as multivendor was in the past. The premise of Wikibon’s research on hybrid cloud is that there are many reasons why hybrid and multicloud solutions are needed, and even preferable.

Why hybrid?

There are many reasons why a single solution would be easiest – a single skill set, leverage on pricing, and simplified operations and interoperability are just the beginning. But there is now a general consensus on some of the reasons why hybrid cloud is needed, backed up by the chief executives of Amazon Web Services Inc., VMware Inc. and Nutanix Inc., among others, in video clips below from SiliconANGLE’s video studio theCUBE — in particular from VMware CEO Pat Gelsinger:

  1. The laws of physics: Latency and the speed of light are limiting factors for the distance between data and compute for many applications.
  2. The laws of economics: Bandwidth and data movement costs money (reminder: 5G will not make the laws of physics and economics disappear).
  3. The laws of the land: Governance, Europe’s General Data Protection Regulation, the edge and the “internet of things” will make this more prominent.

Public cloud solutions are often described as frictionless, and good private cloud solutions focus on simplicity, but it’s early days in hybrid cloud, which today is neither simple nor friction-free. Hybrid cloud today is less of a product or solution than it is a combination of things.

Wikibon’s David Floyer put forth a Hybrid Cloud Taxonomy in order to understand the major differences among the myriad offerings on the market today, and where we believe they should be heading. The taxonomy is a broad spectrum that digs into the nuances and complexities of hybrid cloud, multicloud and edge computing (watch out for terminology that confuses or conflates edge with data centers).

The more important thing to watch is not what term is being used but how the maturation of these solutions has an impact on application architecture and the role of data. Applications have moved from monolithic to microservices, and as discussed by IBM Corp. Fellow Bala Rajaraman, there are dimensions of complexity in programming models and integration, data movement and governance, and security.

Key players

Since there’s no general consensus around hybrid cloud solutions, and from a taxonomy standpoint, our position is that this is a number of markets and there is not a single market leader. As a result, expect many vendors to plant a flag claiming leadership on the hill that they have climbed.

In public cloud, each major player has a different positioning, and although AWS has leadership in infrastructure as a service, Microsoft Corp. is a strong second with many software-as-a-service business productivity offerings and Google LLC has a strong play with data services. These leaders in public cloud are all of major importance as part of examining hybrid cloud.

So are the leaders in data center and private cloud. VMware and its parent Dell Technologies Inc., Microsoft (again), Oracle Corp., IBM, Cisco Systems Inc., Hewlett Packard Enterprise Co. and many others have large installed bases that are in the process of creating private clouds, modernizing applications and highlighting the value of data with AI.

The relationship among the big three public cloud providers and other provider is changing at a rapid pace. AWS has a sprawling ecosystem and the AWS Marketplace is likely the most important for software today. The Microsoft of today is a kinder and gentler partner than the one that many of us remember from the days when Windows wielded its dominance to crush competition. Whole ecosystems have been created from technology that sprung from Google papers, such as the big-data framework Hadoop and the software container orchestration service Kubernetes.

Considerations and opportunities

On Kubernetes, co-creator Joe Beda said that “we never wanted to pretend that Kubernetes was going to be this magic layer that was going to make differences between different environments disappear. What we did want to do, though, was actually find the commonalities and minimize the extra differences that didn’t need to be there.”

Management of heterogeneous environments has been something that IT has tried to address for decades. The fabled “single pane of glass” is typically more pain for the administrators who have to fight with it.

There is hope that modern architectures can leverage APIs and lead toward a more manageable environment. As Cisco’s Ronnie Ray said, “software can have a unifying effect” on platforms and marketplaces. Speaking of Cisco, networking between environments is one of the planes of the taxonomy. Software-defined wide-area networks are a fast growing solution thanks to its enablement of hybrid, multicloud and edge solutions, as I explored in my article Cisco’s Software Bridge to Multicloud.

Although SaaS offerings are part of the cloud landscape, there are a number of services that should be considered in the context of hybrid cloud, most notably security and data protection. The reason to call these out specifically is that they are business-critical services that, if not considered holistically across all environments, can put companies at risk to data loss or security vulnerabilities.

IBM’s $34 billion acquisition of Red Hat Software Inc. highlights the opportunity in hybrid and multicloud. Red Hat Linux and OpenShift are supported across most public and private cloud environments, proving the consistency across environments that customers are looking for in this complex landscape.

Action Item

Data and the application portfolio that interacts with data are the starting points to determining the services needed, and therefore the architectures that can deliver on business requirements. The balance between standardization and flexibility is more challenging than ever. Trusted partners that can educate and iterate in this fast-changing world are critical.
