The World's First Autonomous Live Migration Engine.
Exostellar continuously adapts your EC2 fleet, scaling up during spikes, shrinking luring dips, and shifting to Spot with 99.7% reliability-all while your jobs are running.

You're not overprovisioning because you want to. You're doing it because you have to.

Most engineering teams size infrastructure for peak demand. Yet, most workloads run well below that, leading to:

checkbox
50-60% idle compute
checkbox
Bloated EC2 costs
checkbox
Long queues and resource contention
This overprovisioning is one of the biggest sources of cloud waste and inefficiency.

Introducing Exostellar’s Workload Optimizer

An AI-driven orchestration engine that dynamically scales CPU and memory in real time based on actual workload demand. By continuously monitoring workload behavior, it automatically right-sizes instances, eliminating overprovisioning with zero manual tuning or code changes.

You're not using On-Demand because it's cheap. You're using it because you don't trust anything else.

Most teams overpay to avoid failure by relying heavily on On-Demand instances for critical workloads because:

checkbox
Reserved and Spot capacity is underutilized
checkbox
High On-Demand costs inflate budgets
checkbox
Risk-averse infrastructure limits cost efficiency
This cautious approach leads to wasted cloud spend and inefficiency.

CUSTOMER SNAPSHOT

How one team cut EC2 costs by 68%

Before
Static provisioning of r6i.32xlarge
$1,868 per job
Manual scaling decisions
Compute idle during runtime dips
With Exostellar
Compute idle during runtime dips
$581 per job
Fully autonomous scaling
Matched usage to real time demand

“Exostellar allowed us to leverage the cost-effectiveness of spot instances with the reliability as-if they were on-demand instances, allowing Astera to run more simulation and physical design workloads resulting in reduced development time and quicker time to market”

— Jitendra Mohan
CEO of Astera Labs
