Why Broadcom is betting on a private cloud comeback

Key Concepts

• VMware Cloud Foundation (VCF): A unified private cloud platform integrating compute, storage, networking, and management.
• vSphere Kubernetes Service (VKS): An upstream-conformant Kubernetes runtime built into VCF.
• Declarative API/Kubernetes Control Plane: The shift toward using kubectl and Kubernetes Custom Resource Definitions (CRDs) to manage both container and VM workloads.
• Data Sovereignty: The increasing enterprise requirement to maintain control over data and infrastructure location, particularly in Europe.
• GitOps: The methodology of managing infrastructure and application deployment through version-controlled repositories (e.g., Argo CD, Flux).
• Cloud-Native Maturity: The transition of open-source projects from "lab experiments" to core enterprise infrastructure.

1. The Evolution of the Private Cloud

The industry is witnessing a "full circle" movement where enterprises are bringing cloud-native stacks back on-premises. While the last decade was defined by a shift toward hyperscalers, modern enterprises now prioritize data sovereignty and infrastructure control. VMware by Broadcom is responding to this by aligning its enterprise-grade platform with the CNCF (Cloud Native Computing Foundation) ecosystem, moving away from proprietary, closed-source models toward community-led standards.

2. Strategic Shift: From Proprietary to Open Source

VMware has pivoted to embrace open-source projects as the standard for enterprise infrastructure. Key examples include:

• Donations to CNCF: VMware donated projects like Velero (backup/recovery), Contour (ingress controller), and Harbor (container registry) to the community to foster collaboration and reduce vendor lock-in.
• Upstream Contributions: VMware is consistently ranked among the top five contributors to the Kubernetes project, a commitment that began with the 2018 acquisition of Heptio.
• Focus on Standards: By adopting open protocols like OpenTelemetry, VMware ensures that its platform remains interoperable, allowing customers to avoid "reinventing the wheel" with proprietary internal tools.

3. The VCF Platform Architecture

VCF is no longer a "bundle" of products but a cohesive platform. The architecture is designed to eliminate the "split-brain" scenario where IT teams manage VMs and containers as disparate silos.

• Unified API Surface: The platform uses a Kubernetes-style declarative API. Whether provisioning storage, networking, or compute, users interact with the system via kubectl and CRDs.
• Supervisor Control Plane: VCF utilizes a Kubernetes control plane to manage the underlying infrastructure, effectively treating the private cloud with the same operating model as a public cloud (e.g., AWS or Azure).
• VM/Container Convergence: The platform supports both traditional VMs and containers. Notably, VMware offers hardened vSphere pods that provide the security of a segregated kernel while maintaining the agility of a containerized workflow.

4. Operational Frameworks and Methodologies

• GitOps Integration: VMware advocates for GitOps as the standard for operational maturity. By exposing a Kubernetes API surface, VCF allows teams to use standard tools like Argo CD or Flux to automate the lifecycle management of their entire infrastructure.
• SaaS Strategy: Broadcom has shifted away from a SaaS-first business model for its core infrastructure, focusing instead on delivering a robust, on-premises private cloud that provides the "dial tone" of a public cloud without the complexities of a split-brain architecture.

5. Notable Quotes

• "We’re not shy about saying that we think the way that you should run these sort of modern workloads is through a GitOps practice." — Miles, VMware by Broadcom.
• "It’s not just that we have Kubernetes as an add-on. Kubernetes is fundamental to how we are building our platform too." — Miles, VMware by Broadcom.
• "The private cloud should be exactly like [the public cloud]... whether it is a whole set of VMs or a whole set of containers... it should be done in one pipeline, one workflow." — Jad, VMware by Broadcom.

6. Synthesis and Conclusion

The core takeaway is that VMware by Broadcom is repositioning itself as an enabler of the modern, cloud-native enterprise. By integrating Kubernetes directly into the foundation of its infrastructure (VCF) and adopting a declarative, API-driven management model, the company is bridging the gap between traditional VM-based workloads and modern containerized applications. This strategy prioritizes customer demand for data sovereignty, operational consistency, and the use of open-source standards, effectively providing a "public cloud experience" within the secure, controlled environment of a private data center.
