title: "Introducing Atlas Gen2 on AWS and GCP for M30+ Dedicated Clusters"
description: "MongoDB Atlas introduced Gen2 for M30+ Dedicated Clusters on AWS and GCP, addressing the common inefficiency of overprovisioning storage to meet IOPS requirements. Gen2 runs on newer ARM-based processors, delivering a statistically significant 15-20% reduction in CPU utilization and approximately 45% lower read and write latency in internal pilots. It introduces extended standard IOPS that can be provisioned independently from storage capacity, allowing teams to scale performance without adding unused storage and gain more precise control over infrastructure costs. No application changes or migration are required; teams retain the same Atlas API, connection strings, and operational model while benefiting from newer infrastructure underneath. Gen2 is available in supported AWS and GCP regions across APAC and Europe, with limited U.S. availability on GCP, and existing customers can evaluate upgrade opportunities for eligible M30+ clusters."

# Introducing Atlas Gen2 on AWS and GCP for M30+ Dedicated Clusters

[MongoDB](https://yomu.fyi/company/mongodb) · Jul 7, 2026

**Type:** Announcement

## Summary

MongoDB Atlas introduced Gen2 for M30+ Dedicated Clusters on AWS and GCP, addressing the common inefficiency of overprovisioning storage to meet IOPS requirements. Gen2 runs on newer ARM-based processors, delivering a statistically significant 15-20% reduction in CPU utilization and approximately 45% lower read and write latency in internal pilots. It introduces extended standard IOPS that can be provisioned independently from storage capacity, allowing teams to scale performance without adding unused storage and gain more precise control over infrastructure costs. No application changes or migration are required; teams retain the same Atlas API, connection strings, and operational model while benefiting from newer infrastructure underneath. Gen2 is available in supported AWS and GCP regions across APAC and Europe, with limited U.S. availability on GCP, and existing customers can evaluate upgrade opportunities for eligible M30+ clusters.

## Context

MongoDB Atlas customers on AWS and GCP have faced the trade-off of overprovisioning storage to achieve required IOPS, resulting in wasted capacity and higher costs. Atlas Gen2 for M30+ Dedicated Clusters introduces ARM-based processors and independent IOPS scaling to improve performance and cost efficiency without requiring application changes.

## Approach / What changed

Atlas Gen2 for M30+ Dedicated Clusters on AWS and GCP uses ARM-based processors and introduces extended standard IOPS that can be provisioned independently from storage capacity, without requiring application changes or migration.

## Takeaways

- Gen2 delivers 15-20% lower CPU utilization and approximately 45% lower read and write latency compared to previous generation infrastructure.
- IOPS can be scaled independently from storage capacity, eliminating the need to overprovision storage for performance requirements.
- No application changes or migration are required; teams keep the same Atlas API, connection strings, and operational model.

## FAQ

### How does Gen2 improve performance?

Gen2 runs on ARM-based processors, resulting in a statistically significant 15-20% reduction in CPU utilization and approximately 45% lower read and write latency in internal pilots.

### Can I scale IOPS without adding storage?

Yes, Gen2 introduces extended standard IOPS that can be provisioned independently from storage capacity, allowing you to increase IOPS without overprovisioning storage.

### Do I need to migrate my application?

No, Gen2 requires no application changes, vendor switch, or rearchitecture. Teams retain the same Atlas API, connection strings, and operational model.
