The 5 Pitfalls of DIY Kubernetes

A key element of the cloud-native ecosphere is container orchestration—and according to industry watchers, Kubernetes is rapidly emerging as the front-runner. Across every sector, enterprises are choosing K8s to increase stability and scalability while accelerating cloud-native application development.

Integrating Kubernetes into your existing IT environment on your own can be time-consuming and difficult. In this post, we’ll look at some negatives you can expect from deploying a do-it-yourself K8s solution and how they can be addressed.

1. DIY Kubernetes is complex and time-consuming 

A production-ready Kubernetes deployment requires careful configuration of a complex blend of components, services, plugins, and add-ons. Such a deployment can take weeks or even months, resulting in an over-complicated solution. In addition, adding Kubernetes as another IT silo outside of your VMware unnecessarily increases infrastructure complexity.

2. The learning curve is steep

Understanding how to deploy and manage Kubernetes means building expertise in-house, which can be challenging and costly. That time and effort could be more profitably spent building integrations and supporting the platform.  

3. You’ll have a huge monitoring and maintenance blind spot 

Kubernetes doesn’t automatically alert you to issues in essential components. If those components crash, your cluster may behave unpredictably. Understanding which features need oversight—such as log collection, workload monitoring, certificate management, and network isolation—takes research and time.  

4. You’re taking a big security risk

A system failure can cost your company hundreds of thousands in lost revenue. Kubernetes and its open source elements are evolving quickly, so keeping software up-to-date is one of the best ways to reduce security risks. Is your organization in a position to install the latest upgrades and patch security exploits quickly or are they already dealing with a backlog of tickets?  

5. Support will be slow and inconsistent

Troubleshooting the issues that arise can be challenging and time-consuming for IT teams who are unfamiliar with Kubernetes. They’ll need to do a lot of research and still might not get the right answers. Supporting Kubernetes also takes time away from maintaining critical enterprise applications.  

Fast path to Kubernetes for VMware shops

Although it is possible to create a custom cluster from scratch, why piece together a DIY Kubernetes solution in-house when you can choose a pre-integrated and tested solution that delivers production-ready Kubernetes to your enterprise?  

If you’re looking for a fast, low-risk path to Kubernetes and cloud-native practices for your existing VMware ecosystem, Pivotal Container Services (PKS) offers an enterprise-ready K8s stack that delivers automated monitoring and upgrades, high availability, health checks, enterprise-grade security, and 24/7 support across both clusters and containers. By making practices like cloud-native, continuous delivery, and microservices possible, PKS speeds Kubernetes adoption while allowing developers to innovate faster.
