Deep dives
The Need for Virtualizing Kubernetes
Virtualizing Kubernetes addresses inefficiencies often found in across enterprise environments, which typically feature numerous small Kubernetes clusters. While Kubernetes was designed for large-scale distributed systems, many organizations underestimate its ability to effectively manage resource allocation across hundreds of nodes. Instead of creating separate small clusters for different teams, which can worsen resource underutilization, adopting virtual clusters streamlines workloads, allowing multiple teams to share a single large cluster efficiently. This approach not only enhances resource utilization but also simplifies management and operational complexity.
