and the benefits it can bring to your adtech business.

Features our Adtech customers use to succeed

Adtech companies operate on a massive scale, with millions of users sending data in real-time. Kubernetes offers great autoscaling mechanisms, but we thought you deserved something a little extra to become a leader in your field.

Real-time autoscaling

CAST AI scales applications based on actual usage, provisioning the just-in-time capacity your application needs.

Open to open source

We play well with open-source solutions like Horizontal Pod Autoscaler, KEDA, and other projects that focus on autoscaling.

AI-driven instance selection

Our platform picks the best instance types and sizes to meet your application’s requirements at the lowest possible cost.

Other features CAST AI users benefit from


Bin packing nodes

Our autoscaler uses bin packing algorithms to identify the most optimal pod groupings and reduce your cluster cost.

Spot instance automation

We handle spot instance provisioning for you. No need to pick instance types or configure anything; CAST AI does that for you.

Spot fallback

Our spot instance automation keeps your workloads running even when all spot instances are gone by switching to on-demand.

Cost monitoring and reporting

CAST AI uses universal metrics to help you analyze and forecast your budget per project, cluster, and deployment.

No vendor lock-in

Our platform is vendor-neutral and chooses the optimal solution for your cluster without forcing you into any long-term commitments.

Change management logs

We use Terraform provider with full visibility and logs, enabling you to track all the changes happening across your clusters.

Customer stories

These companies saved 50%+ on cloud costs using CAST AI.

“Partnering with CAST AI has been a big success for Branch, saving us several millions of dollars per year in AWS Cloud compute costs for our Kubernetes clusters while maintaining our reliability SLAs.”

Mark Weiler
SVP Engineering at Branch

“People running Kubernetes clusters that don’t utilize spot instances would benefit a lot from CAST AI – or anyone who feels like they’re overprovisioning their infra when they don’t need to be so. It’s a really unique solution.”
