What is Kubernetes?
Kubernetes v1.37 promotes gang scheduling to Beta, closing the gap with dedicated ML schedulers.
Kubernetes v1.37 is a systematic Beta-graduation release, pushing memory QoS, native histograms, changed block tracking, rootless kubelet, and workload-aware scheduling all out of Alpha in a single cycle. The release is most notable for elevating gang scheduling (PodGroup + Workload APIs) to Beta alongside shared DRA resource claims for PodGroups — directly addressing the fragmented, bolt-on tooling that AI/ML operators have relied on for distributed training jobs. HPA scale-to-zero is also now Beta by default, removing a common reason to reach for Keda or similar add-ons.
What is Rivet?
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
Kubernetes vs Rivet: editorial side-by-side

Kubernetes v1.37 promotes gang scheduling to Beta, closing the gap with dedicated ML schedulers.
◆ Current state
Kubernetes v1.37 is a systematic Beta-graduation release, pushing memory QoS, native histograms, changed block tracking, rootless kubelet, and workload-aware scheduling all out of Alpha in a single cycle. The release is most notable for elevating gang scheduling (PodGroup + Workload APIs) to Beta alongside shared DRA resource claims for PodGroups — directly addressing the fragmented, bolt-on tooling that AI/ML operators have relied on for distributed training jobs. HPA scale-to-zero is also now Beta by default, removing a common reason to reach for Keda or similar add-ons.
◆ Where it's heading
v1.37 continues a deliberate Arc toward native AI/ML infrastructure. DRA Extended Resource support reached GA, gang scheduling Beta, and in-place pod resize acquired a preemption alpha — together they form a coherent stack for multi-tenant GPU clusters. The pattern is Beta-now, GA-next: workload-aware scheduling and CSI changed block tracking are positioned to reach GA in v1.38 or v1.39. Kubernetes is methodically absorbing capabilities that previously required third-party schedulers (Volcano, Ray) and backup tooling.
◆ Prediction
The next release will likely promote Workload-Aware Scheduling and DRA shared-resource claims to GA, given the two-release Beta pattern and the obvious demand signal from the AI infra space. Rootless kubelet reaching GA is also a near-term candidate.
Rivet
8.8DEVOPS
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
◆ Current state
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
◆ Where it's heading
Rivet is building toward a single answer to a specific question: where does agent-generated, user-facing software actually run? The BYOC move unlocks regulated industries and large enterprises who can't send data to a SaaS control plane. MCP turns Rivet's Actors into something any AI client can discover and call without bespoke integration. Dynamic Apps makes Rivet the runtime, not just the infrastructure, for user-generated software. The through-line is that Rivet wants every AI agent — whether built by a developer or generated at runtime — to run on the Actors primitive with Rivet managing the lifecycle.
◆ Prediction
BYOC on AWS/GCP is the foundation; Azure support and SOC 2 certification are the logical next steps to close enterprise deals. Expect MCP to expand to more clients (OpenAI Codex, Copilot, Windsurf) as the MCP ecosystem grows, and Dynamic Apps to get versioning and rollback — the missing piece for user-facing production deployments.
