What are the Considerations for Shifting from Tanzu to Other Kubernetes Platforms?

Migrating away from VMware Tanzu requires careful evaluation to ensure the new Kubernetes platform can handle production workloads efficiently. Key factors include:

• Production Readiness: Automated cluster lifecycle management, smooth upgrades, and high availability are essential to maintain stability during scaling and updates.
• Multi-Environment & VM Support: Unified management of containers and VMs, compatibility with diverse hardware and OS, and consistent operations across on-premises and edge deployments.
• Simplified Operations: Declarative management, intelligent node scaling, and plugin automation reduce operational complexity and costs.
• Visibility & Observability: A unified interface for monitoring, logging and alerting with real-time data visualization simplifies troubleshooting and performance optimization.
• Networking & Security: Zero-trust networking, fine-grained RBAC, secure image management, and integration with enterprise identity systems are critical for protecting workloads.

Several platforms — such as Red Hat OpenShift, Rancher, Arcfra Kubernetes Engine (AKE), Nutanix, and public cloud services like EKS & AKS — address these needs to varying degrees.

In particular, AKE (of Arcfra Enterprise Cloud Platform) stands out as a robust Tanzu alternative that not only meets these considerations but also delivers integrated virtualization capabilities and enhanced operational simplicity:

• Ensures enterprise-grade stability with rolling upgrades, built-in HA, and node auto-healing.
• Provides VM and Kubernetes convergence, enabling unified resource management across virtualized and containerized workloads.
• Offers intelligent automation for cluster scaling, patching, and workload scheduling with minimal manual intervention.
• Delivers a centralized, visual operations center for full-stack observability, from infrastructure to applications.
• Enhances security and networking with microsegmentation, workload isolation, and identity-based access controls.
