Principled Technologies (PT) testing showed vSphere Kubernetes Service sustained more throughput and lower latency for a Kafka workload without adding overhead.
PALO ALTO, CA, UNITED STATES, January 7, 2026 /EINPresswire.com/ — A new hands-on study from Principled Technologies (PT) demonstrates that virtualized Kubernetes deployments using VMware vSphere Kubernetes Service (VKS) with VMware Cloud Foundation (VCF) can deliver substantially better performance than a bare-metal Red Hat OpenShift Container Platform (OCP) solution for both modern streaming and traditional OLTP workloads.
The study compared identical four-node Dell PowerEdge R640 clusters, configured with either VKS on VCF or OCP on bare metal, running two real-world workloads: an Apache Kafka producer benchmark workload and an online transaction processing (OLTP) workload on PostgreSQL. According to the report, the VKS configuration achieved up to 73 percent greater throughput and up to 78 percent lower latency…
