VMware has initiated the Workload Conformance Working Group within the Kubernetes community to establish a uniform standard for verifying workload performance across hybrid Kubernetes clusters.
Addressing reliability gaps in hybrid cloud Kubernetes deployments
Despite cloud-native software’s promise of application portability, VMware notes significant variability in how apps perform across hybrid cloud environments. Existing Kubernetes certifications target clusters and specific workloads like AI, but they lack tools to verify the behavior of cloud-native applications themselves. This gap leads to redundant manual checks by cluster operators before upgrades or maintenance.
- The new working group aims to define objective requirements covering security, resilience, resource consumption, networking, storage, API usage, and observability for Kubernetes workloads.
- All requirements must allow automated, repeatable testing—reducing subjective assessments.
- VMware contributed its VM API to the CNCF Sandbox, enabling VMs to run under Kubernetes with support for multiple hypervisors including ESXi.
- This initiative builds on earlier but less successful VMware efforts to integrate Kubernetes with vSphere.
With hybrid environments increasingly mixing containerized apps and legacy VMs, the standard is broadly relevant to vendors and users wanting consistent workload operation regardless of cloud infrastructure. The working group is still defining the scope and specifications, marking an early but pivotal step toward addressing hybrid Kubernetes workload challenges.
