All components of the open DXP (CMS + CDP + marketing automation) can be hosted in your Kubernetes cluster in your cloud. They can be on-premise or cloud.
That Drupal scales is old news. A significant portion of the web is already on Drupal. Moving your Drupal to Kubernetes is certainly possible and can result in significant cost reduction.
We can also increase the efficiency of developers. How? Hundreds of Dropsolid Developers have been deploying Drupal sites on different architectures for years. The Dropsolid platform is target agnostic. Developers using the Dropsolid platform do not even feel that they are deploying to Kubernetes, VMs, or wherever.
You can have Zero downtime deployments too, enabled by Kubernetes.
Spare yourself the hassle of setting all this up from scratch. Let the developers focus on writing functionalities. Let Dropsolid handle the rest.
