CloudFix Introduces Lambda Graviton Migration
Migrate Lambda functions from x86 to Graviton2 for up to 20% cost savings with improved performance. CloudFix identifies eligible functions automatically.
Are you looking to reduce your AWS Lambda costs while improving performance? CloudFix is excited to announce our new Lambda Graviton Migration Finder/Fixer, designed to automatically identify and migrate eligible Lambda functions to AWS Graviton architecture while upgrading outdated runtimes. We are rolling out this feature over the next few weeks, so be sure to check your CloudFix dashboard!

The Graviton Success Story
The AWS Graviton journey has been remarkable to witness. Since the introduction of the first-generation Graviton processor in 2018, AWS and Annapurna Labs have maintained an impressive pace of innovation. The rapid evolution from Graviton2 to Graviton3, and now to the generally available Graviton4, demonstrates AWS’s commitment to ARM-based computing excellence.
Each new generation has delivered substantial improvements in price-performance ratio:
- Graviton2 offered up to 20% cost savings over x86
- Graviton3 brought 25% better compute performance than Graviton2
- Graviton4, released less than two years after Graviton3, delivers up to 30% better performance than Graviton3
This rapid iteration – with Graviton4 arriving just 18 months after Graviton3 – shows AWS’s aggressive push to lead the ARM-based cloud computing revolution.

AWS Made Easy Graviton 4 Deep Dive
The Power of Graviton for Lambda
AWS Graviton processors, built on 64-bit ARM architecture, deliver significant performance improvements and cost savings compared to x86-based instances. When you migrate your Lambda functions to Graviton, you can expect:
- Up to 20% cost reduction
- Improved performance and efficiency
- Better price-to-performance ratio
- Enhanced energy efficiency
Why Upgrade Now?
Many organizations are still running Lambda functions on older runtimes that are approaching their end-of-support dates:
- Node.js 14.x (December 4, 2023)
- Python 3.7 (December 4, 2023)
- Java 8 (January 8, 2024)
- Node.js 16.x (June 12, 2024)
Our new Finder/Fixer not only migrates your functions to Graviton but also automatically updates them to supported runtime versions, helping you stay ahead of deprecation deadlines.
The CloudFix Lambda Graviton Migration Advantage
Our solution offers several key benefits:
-
Automated Analysis: We scan your AWS environment to identify Lambda functions that can benefit from Graviton migration and runtime updates.
-
Intelligent Validation: Our system checks that your functions are compatible with Graviton before recommending a change.
-
Safe Migration: The migration runs through AWS Systems Manager in your account, after you approve it, providing:
- Complete audit trail
- Rollback capabilities
- Minimal risk to your applications
-
Cost Optimization: We focus on the functions where the migration is worth making, to maximize your ROI.
How It Works
CloudFix’s finder reviews your Lambda functions read-only and identifies the ones that can safely move to Graviton and a supported runtime, along with the potential savings. Each opportunity appears in your Recommendations for you to approve. Once you approve, the fixer runs as an AWS Systems Manager Automation runbook in your own account, updating the function to a supported runtime and switching its architecture to arm64 (Graviton). Every execution is logged, so you can track the migration and verify function performance.
Real-World Impact
Let’s look at a practical example:
A Lambda function running on x86 with Python 3.7 and costing $1,000 annually can be:
- Upgraded to Python 3.11
- Migrated to Graviton
- Resulting in $200 annual savings
Have a look at this example in the CloudFix dashboard:

As yoou can see, each individual function doesn’t save too much. But, there can be hundreds or thousands of these functions in a typical AWS account. In my personal AWS account, I have more than 50 that do various digital housekeeping tasks. Now multiply the potential savings across your entire Lambda function portfolio, and the savings become substantial! This is similar to unused elastic IP addresses – small individual savings but they add up fast!
Getting Started
To take advantage of the Lambda Graviton Migration feature:
- Log in to your CloudFix dashboard
- Navigate to the Finders section, and go to Advanced
- Look for the “Lambda Graviton Migration” Finder
- Review identified opportunities and potential savings
- Using our new “Create Tickets” button, you can create tickets for the migrations you want to implement. We will dive into the details of the “Create Tickets” button in a future blog post.
The Modernization Benefit
We are focused on the cost benefits of migrating to Gravton, but the modernization benefits are significant. With large AWS deployments, it is easy to have a Lambda function that just sits there and does its job, but has not been updated in years. By scanning all of your Lambda functions, you can identify these long-forgotten Lambda functions and make sure they are using the latest runtime version. Running a deprecated runtime may not be an issue in the short term, but if Murphy’s Law is any indicator, it will be an issue at the worst possible time.
Conclusion
The CloudFix Lambda Graviton Migration Finder/Fixer offers a safe, automated way to modernize your Lambda functions while reducing costs. By combining runtime updates with Graviton migration, you can ensure your serverless applications are both cost-effective and future-proof.
