As Kubernetes® continues to reign as the worldwide container orchestration system of choice, many organizations and independent software vendors (ISVs) are realizing that its capabilities could be an essential key to ongoing and future business success. In a survey of 750 members of the Cloud Native Computing Foundation, 93% of organizations are running Kubernetes in production or piloting it in test environments, according to the Cloud Native 2024 survey. But how many of these organizations are truly free to innovate with Kubernetes?
When Kubernetes emerged on the IT development scene, there were three primary options for deploying it:
The first option wasn’t customizable; the second was impossible for organizations that didn’t have the skills, experience, and resources to DIY; and the third was easy to use with cloud-provided add-ons, which would add to cost and could create vendor lock-in.
Fortunately, another option exists today—a “best of both worlds” approach that delivers flexibility, a single operating model, and accelerated innovation for long-term operational success. It’s a complete and open Kubernetes platform provided by a vendor (like Nutanix) that does all the assembly, testing, and more. You get the modular architecture, customization, and a single, unified platform that runs the same way across every IT environment, whether it’s on-premises, in the cloud, or on the edge.
First, it’s important to define a couple of terms:
A truly open platform is one in which none of the piece components have been modified by a vendor or include an extra proprietary layer on top of the Kubernetes system, both of which can greatly restrict compatibility and its open nature. Open also means that it’s modular, or open to modification by the user, versus being a black box. Open platforms expose open APIs instead of hiding them behind proprietary ones, to ensure your applications stay portable across any Kubernetes environment, which gives you the flexibility to place applications and other workloads where they operate the best.
A complete and open platform enables organizations and ISVs to innovate more freely and adapt to technological advancements and fluctuations in market trends and customer demand as they occur.
While many vendors offer Kubernetes solutions, not all approaches are created equal. Some proprietary platforms modify open-source projects, introduce custom APIs, or limit portability between environments. Others bundle critical production features into closed extensions, creating a "walled garden" that can keep you from taking advantage of the latest features and capabilities.
Vendors typically do this to add value that only they can offer customers, but these closed systems can introduce serious risks:
Some vendors have found ways to add value for customers while also keeping their platforms open. They simply add their custom or proprietary extensions and automation around the open components. This guards against vendor lock-in and gives customers peace of mind that there is an off-ramp to other vendors or systems if they ever need it.
Choosing a complete and open Kubernetes platform unlocks several important strategic advantages:
The flexibility offered by a complete and open Kubernetes platform is critical in today’s fast-paced digital world. It allows you to develop applications in a public cloud, for instance, where capacity can scale up or down as needed on demand—and then move less dynamic production workloads to the edge or on-premises for heightened performance and potentially lower costs.
An open Kubernetes approach is equally vital for ISVs. Benefits include:
Ultimately, open platforms create a healthier ecosystem for open source development and technology itself—one that rewards innovation, motivates developers to continually improve their solutions, and gives customers many choices. This is essential for the health and continued growth of the CNCF community.
In addition to choosing an open Kubernetes platform, it’s important to find one that is modular. A modular system means all key components—like networking, ingress controllers, monitoring, and security—are included by default for a fully production-ready platform. However, it’s easy to customize or swap out components as desired.
For example, an open Kubernetes platform might default to a popular open source load balancer but also allow you to replace it with another open or commercial solution without breaking the overall system. This flexibility is a serious step up from monolithic proprietary platforms, where customization is limited or even impossible.
Modularity enables you to tailor your Kubernetes deployments to your organization’s unique needs without hindering your ability to adapt to changing requirements or implement innovative new solutions.
The benefits of a complete and open, modular Kubernetes approach are helping to improve organizations in many ways today.
For instance, some organizations develop applications in public clouds to take advantage of flexible, pay-as-you-go pricing and near-infinite scalability during fluctuating demand periods. Later, they may move production workloads to on-premises data centers to optimize costs, or even onto cruise ships, military bases, or other remote edge sites where public cloud access is nonexistent.
By adopting a complete and open Kubernetes platform, these organizations maintain one consistent architecture, one security model, and one operational model—regardless of environment. This platform is designed to reduce management overhead, strengthen security, and increase agility.
Organizations evaluating Kubernetes platforms should keep one priority at the forefront: future-proofing.
The CNCF and cloud-native landscape continue to evolve at incredible speed. New projects, standards, and solutions emerge constantly. Choosing an open and modular Kubernetes platform positions you so tomorrow’s innovations can adopt with ease.
A complete and open Kubernetes platform also simplifies hybrid and multicloud operations, which are quickly becoming the default IT model across every industry. Having a single, unified platform that works across environments will help you manage costs, security, and performance as your organization grows.
The future of Kubernetes lies in platforms that are both complete and open. They deliver the production-grade solutions all assembled and ready to deploy—along with the openness, modularity, and flexibility to drive innovation and avoid lock-in.
Choosing a complete and open Kubernetes platform today isn’t just about adopting the right technology. It’s about building a foundation for operational efficiency, accelerated innovation, vendor independence, and long-term competitive advantage.
