What you need to know about Kubernetes enterprise platforms



Kubernetes enterprise platform is providing organizations cloud-agnostic solutions that they can use to leverage a scalable, secure, and cost-effective cloud. It also allows enterprises to use a hybrid cloud model.

Without a doubt, Kubernetes has become one of the best tools for container orchestration. It's an open-source, extensible, and modular platform that offers many functionalities. More info at

Considerations of Kubernetes enterprise platform

There are two types of shared clusters--single-tenant and multi-tenant.

The former is dedicated for use by a single team and features a simpler model. This is because all API access and codes come from one team.

On the other hand, a multi-tenant cluster is shared by multiple tenants or application teams. They access the same cluster and are only designated a namespace that defines one team from another.

Whether you use a single-tenant cluster or a multi-tenant cluster depends on the size of your organization.

A small company would benefit from each team building, managing, and owning its own cluster. Medium to large enterprises, however, would be more efficient with a single platform team handling multi-tenant clusters.

Between the two types of clusters in a Kubernetes enterprise platform, multi-tenant clusters are more advantages over the other kind.

This is because…

    Costs are shared among application teams, effectively reducing maintenance overhead.

    Cluster nodes are easier to fill up with pods, allowing for better resource utilization and efficiency.

    The proliferation of versions is reduced because the version and upgrade schedule is consistent.

    Add-on features and security policies are contained in a single consistent platform

    Integration with existing enterprise tools is easier.

Moreover, there is dedicated support staff available to assist organizations in various functions, including Kubernetes deployment.

However, there are concerns about security, access control, and the use of resources with multi-tenancy.

By following Kubernetes best practices in building, owning, and managing multi-tenant clusters, such concerns are addressed.

Some of the best measures to take are:

    Regulate access to resources by implementing role-based access control.

    Ensure that pods are running with appropriate privileges by implementing appropriate security policies.

    Limit each team's access to resources and the ability to auto-scale clusters by enabling resource quotas.

    Ensure pods communicate with each other and with other network endpoints by implementing network policies that enforce the process.

    Provide pods that access cloud resources with IAM credentials.

By taking these measures, you can use multi-tenant clusters to your advantage.

Kubernetes enterprise platform: Managed vs DIY

Managed Kubernetes is delivered as a service by either:

    Service providers: Docker Enterprise, Platform9, Redhat Openshift, etc.

    Cloud providers: Amazon EKS, Azure AKS, Google GKE

DIY Kubernetes, on the other hand, means you manually do the following:

    Download Kubernetes

    Set up the open-source orchestration tool

    Run the platform or use an open-source tooling

While it is difficult and time-consuming to run DIY Kubernetes, the managed option comes with its share of issues.

For instance, authentication can't be customized or set as a single sign-on. You must first authenticate with the cloud provider.

Also, you still need to own and manage the worker nodes, instead of relying on the orchestration tool to manage clusters fully.

For any issues, however, there are existing solutions.

Consult with Kublr, a provider of a comprehensive container orchestration platform that is optimized for enterprises, especially large ones.
