What Kubernetes is not
Kubernetes is not a platform as a service (PaaS). It doesn't dictate many of the important aspects of your desired system; instead, it leaves them up to you or to other systems built on top of Kubernetes, such as Deis, OpenShift, and Eldarion. For example:
- Kubernetes doesn't require a specific application type or framework
- Kubernetes doesn't require a specific programming language
- Kubernetes doesn't provide databases or message queues
- Kubernetes doesn't distinguish apps from services
- Kubernetes doesn't have a click-to-deploy service marketplace
- Kubernetes allows users to choose their own logging, monitoring, and alerting systems
