Devzero features
- Real-time cost monitoring. Shows CPU, memory, GPU usage and cost attribution per department.
- Workload right-sizing. Adjusts CPU, memory and GPU requests per pod to match actual demand.
- Live migration. Instantly moves pods without restarts using checkpoint-restore.
- Spot & GPU optimization. Selects lowest-cost instances and manages spot and GPU resources.
- Multi-cloud support. Works with AWS, Azure, GCP, OCI, OpenShift and on-prem Kubernetes.
- Inference optimization (beta). Measures LLM traffic and routes requests to the cheapest model with caching and failover.
RunsOn features
- Dynamic instance selection. Specify CPU, RAM, architecture or GPU in a label and RunsOn launches the matching EC2 spot or on-demand instance.
- Fast job startup. Typical 30 s from queued to running; warm pools can reduce latency to under 6 s.
- Unlimited machine types. Any EC2 instance type, including x64, ARM64 and GPU, can be used per job.
- S3-backed caching. Add extras=s3-cache to use an unlimited S3 bucket in your VPC for cache storage.
- Nested virtualization. KVM for Linux and Hyper-V for Windows enable Android emulators, VM-based e2e tests and Windows containers.
- Per-job isolation. Each job runs on a fresh VM that is terminated when the job finishes, keeping data private.
