Choosing the right container platform is essential for scaling modern applications. While many focus on ease of use, cost, and scalability, several overlooked factors can significantly impact the success of a Kubernetes strategy. Key considerations include the speed of access to new Kubernetes versions, the duration of support for those versions, the flexibility to run multiple versions on the same host, what’s included in the distribution, and the treatment of virtual machines alongside containers.
Faster access to new Kubernetes releases is vital for staying competitive. VMware’s vSphere Kubernetes Service (VKS) typically offers access to new releases within two months, aligning with major public cloud providers. In contrast, some platforms can take up to seven months. Support duration also matters; VKS provides 24 months of standard support at no extra cost, far exceeding the typical 10-14 months offered by many providers, which can charge for extended support. This extended support window allows organizations to manage upgrades according to their business needs rather than vendor schedules.
The ability to run multiple Kubernetes versions on the same host helps avoid wasteful resource utilization and reduces costs. VKS allows organizations to operate several versions concurrently, improving efficiency. Furthermore, the distribution of tools included with the platform can ease operational burdens. VKS includes essential open-source tools like Antrea and Pinniped pre-installed, ensuring seamless upgrades and consistent performance. Finally, treating both VMs and containers as first-class citizens is crucial. Unlike many legacy platforms that integrate VMs poorly, VMware Cloud Foundation offers a unified management experience, simplifying operations and reducing complexity.
