In today’s dynamic cloud environments, enterprises are forced into a painful trade-off: over-provision for stability or chase savings at the risk of disruption. This tension is especially acute for any stateful workloads on Kubernetes—databases, simulations, AI jobs—that are notoriously hard to move without downtime.
But what if your infrastructure could move those workloads live, without interruption? What if it could automatically scale up or down, based on real usage—not just requests? With Exostellar, it can.
Exostellar’s Patented True Live Migration Technology
Most copycat “live migration” solutions involve some form of disruption—restarts, checkpointing, or service rerouting. Exostellar’s True Live Migration is fundamentally different, and has been running in production environments for years.
It is a continuous, real-time transfer of a running workload—including memory, storage, and networking state—without restarting the application or breaking connections.
Key differentiators:
- Background Memory Copying: Workloads remain active while memory is incrementally copied in the background. There’s no “freeze-resume” cycle.
- Full State Preservation: CPU registers, open network sockets, file handles, and disk state all persist through the migration.
- Persistent Storage Compatibility: Supports EBS-backed volumes—including single-attach types like GP2—by seamlessly detaching and reattaching without downtime.
- IP and Network Consistency: Deep integration with native Kubernetes CNI (e.g., Amazon VPC CNI) ensures that workloads keep the same IP address, avoiding session drops or DNS churn.
- No Application Changes Required: Works out of the box with legacy Linux workloads, distributed systems, and containerized apps alike.
This isn’t a trick. It’s not a workaround. It’s the infrastructure adapting to the workload in real time.

Want to see what uninterrupted migration looks like? In the demo:
- A pod with persistent storage, active TCP connections, and running applications is seamlessly migrated across multiple EC2 instance types.
- No pod recreation, no IP changes.
Business Value: Why True Live Migration Is a Game-Changer
Traditional cloud cost optimization forces enterprises into risky decisions: cut spend and risk instability—or over-provision for safety and waste millions. Exostellar eliminates this trade-off with a production-grade, policy-driven True Live Migration platform.
1. Maximize Cloud Savings Without Compromising Reliability
- Reduce over-provisioning by automatically rightsizing instances based on real usage, not static pod requests.
- Run mission-critical workloads on spot instances with confidence.
- Customers like DataRobot have achieved 94% spot usage for stateful, high-performance jobs—saving 50–80% on EC2 without any restarts or downtime.
2. Unlock Elastic Infrastructure for Stateful Apps
- Databases, AI pipelines, EDA simulations, SaaS backends—these are the hardest workloads to migrate and often the most expensive.
- Exostellar enables live movement of stateful workloads, making even legacy and latency-sensitive applications dynamically elastic.
3. Lower Operational Overhead
- No manual scheduling. No reactive firefighting.
- Exostellar’s platform handles scaling, rightsizing, and failover automatically—freeing up DevOps and SRE time to focus on higher-value engineering work.
4. Accelerate FinOps Outcomes
- Exostellar helps FinOps teams move beyond dashboards to real-time enforcement of cost policies—without developer disruption.
- Align compute spend with actual business demand and track optimization ROI down to each migration event.
Built for Production. Proven at Scale.
This technology isn’t a prototype—it’s been battle-tested at scale. Enterprise customers like Astera Labs, Arm, and DataRobot have used Exostellar to run stateful, high-performance workloads on spot infrastructure—with over 94% spot utilization, zero restarts, and no data loss. In a joint test with AWS, Exostellar successfully live-migrated thousands of concurrent EDA jobs, each consuming 8 vCPUs and 32GB of RAM, without interruption. This isn’t theoretical—it’s trusted by some of the world’s most demanding compute users.
Say Goodbye to Over-provisioning Forever
