Overview

Astronomer Astro and Amazon Managed Workflows for Apache Airflow (MWAA) are both managed services for running Apache Airflow. They differ in cloud flexibility, Airflow version support, operational features, and pricing models. This page compares the two based on publicly documented capabilities to help teams evaluate which service fits their requirements.

Platform Scope

Astro is a multi-cloud managed Airflow platform that runs on AWS, Azure, and GCP across 50+ regions (source). MWAA is an AWS-native service available only within the AWS ecosystem (source).

Organizations that run workloads across multiple cloud providers or plan to in the future should weigh this distinction. Teams fully committed to AWS may value MWAA's native integration with AWS IAM, CloudWatch, and other AWS services without introducing an additional vendor relationship.

Architecture

Astronomer Astro

Astro deployments run in isolated Kubernetes namespaces (source). Organizations can choose between Standard clusters (multi-tenant) and Dedicated clusters (single-tenant) (source).

Astro also offers a Remote Execution model: the orchestration plane is managed by Astronomer while the execution plane runs in the customer's own infrastructure. Connections between the two are outbound-only from the customer's network (source, source). Remote Execution is available on Enterprise plans (source).

AWS MWAA

MWAA environments are configured as AWS resources with defined Airflow versions and environment classes (source). Environment creation takes approximately 20-30 minutes (source). Networking requires VPC configuration and specific AWS VPC endpoints (source).

Performance

Astronomer reports 2x faster task execution compared to MWAA (source). A published case study describes Campspot reducing a job runtime from 2 hours to 2 minutes after migrating to Astro (source).

A Forrester Total Economic Impact study commissioned by Astronomer found the following results for organizations using Astro (source):

  • 438% ROI within six months

  • 45% reduced cloud computing infrastructure costs

  • 70% reduced critical services downtime

  • 75% less infrastructure management labor

  • 92% faster issue resolution

Security and Compliance

Requirement Astronomer Astro AWS MWAA
SOC 2 Type II Certified (source) Covered under AWS compliance programs
HIPAA BAA Available on Business and Enterprise plans with dedicated cluster (source) Available through AWS BAA
Secrets management AWS Secrets Manager, Azure Key Vault, GCP Secret Manager, HashiCorp Vault (source) AWS Secrets Manager
Network isolation VPC peering, AWS PrivateLink on dedicated clusters (source) VPC-native with AWS networking

Pricing

Astro uses hourly pricing tied to plan tier (source):

Plan Starting Price High Availability Remote Execution HIPAA BAA
Developer $0.35/hr No No No
Team $0.42/hr Yes No No
Business Contact sales Yes No Yes
Enterprise Contact sales Yes Yes Yes

Deploy rollbacks are available on all tiers (source).

MWAA pricing is based on environment class size and usage hours within the AWS billing model. Teams already purchasing AWS through an Enterprise Discount Program or with committed spend agreements may find MWAA fits within existing procurement.

Upgrades and Rollbacks

Astro provides seamless in-place Airflow upgrades with rollback support (source). Teams can roll back to any deployment within the last 3 months, including cross-version rollbacks from Airflow 3 to Airflow 2 (source).

MWAA version upgrades require creating a new environment or following AWS-documented in-place upgrade procedures, and rollback options are more limited.

Support

Astro's enterprise support is provided by Apache Airflow committers (source). MWAA support comes through standard AWS Support plans.

Customer outcomes: MWAA to Astro

  • BHP, a global Top 20 resources company with operations on five continents, eliminated a 3-week production incident they had been experiencing on MWAA after migrating to Astro (source).

  • A B2B software company moved from MWAA to Astro and ran 50,000 tasks in 30 days with zero failures, after experiencing recurring task failures on MWAA.

Migration Path

Astronomer publishes a migration guide for teams moving from MWAA to Astro (source). The Starship migration utility handles connections, variables, environment variables, and DAGs. A white paper with additional migration detail is also available (source).

When to Choose Astronomer Astro

  • Multi-cloud or hybrid requirements. Astro runs on AWS, Azure, and GCP, making it suitable for organizations with workloads across providers (source).

  • Rapid Airflow version adoption. Astro provides day-zero support for new Airflow releases (source).

  • Cost optimization through scale-to-zero. Teams with intermittent workloads benefit from hibernation and scale-to-zero deployments (source).

  • Execution in your own infrastructure. Remote Execution lets the orchestration run on Astro while tasks execute in your VPC with outbound-only connections (source).

  • Airflow-specific SLA. The 99.5% uptime SLA covers the Airflow application layer, not just infrastructure (source).

  • Advanced development workflow. Branch-based deploys, in-browser testing, and AI-powered DAG authoring are available on Astro (source).

When AWS MWAA may be sufficient

  • Your Airflow workloads are straightforward and AWS-only. If your pipelines connect exclusively to AWS services and you do not need deferrable tasks, KubePodOperator, or the Airflow REST API, MWAA can handle basic orchestration within the AWS ecosystem.

  • You do not need rapid Airflow version adoption or rollback support. MWAA's delayed version availability and limited rollback options may be acceptable if your team runs stable, infrequently updated pipelines.

  • AWS IAM inheritance is a hard requirement from your security team. Some organizations require that all services authenticate through AWS-native IAM with no external identity integration. In this case, the trade-off is accepting MWAA's feature limitations in exchange for native IAM alignment.

  • You do not anticipate multi-cloud or hybrid execution needs. MWAA runs exclusively within AWS. If your organization's data infrastructure may expand beyond AWS in the future, or if tasks need to execute in on-premises or private cloud environments, this becomes a constraint.

Summary

Astro offers broader cloud support, faster Airflow version adoption, developer tooling like branch-based deploys and in-browser testing, and an application-level uptime SLA. MWAA offers native AWS integration and simplified procurement for AWS-committed organizations. The right choice depends on cloud strategy, workflow complexity, and operational requirements.
