Case Study: How We Reduced AWS Costs by 40% Using GraalVM and Serverless Java

At Associative, we are constantly exploring ways to build high-performance, cost-effective digital solutions for our clients. Recently, we tackled a common challenge in modern cloud architecture: the overhead of running traditional Java applications in a serverless environment.

By rethinking our approach to Java deployment, we achieved massive efficiency gains. Here is the story of how we reduced AWS costs by 40% using GraalVM and serverless Java.

The Challenge: The Java Cold Start Problem

Java has long been a powerhouse for backend development, known for its robust ecosystem and enterprise-grade reliability. However, when deployed to serverless environments like AWS Lambda, standard Java applications face significant hurdles:

  • High Memory Consumption: The Java Virtual Machine (JVM) requires a substantial memory footprint just to run.
  • Slow Cold Starts: Just-In-Time (JIT) compilation means the JVM needs time to warm up, resulting in latency spikes whenever a new Lambda instance spins up.

Because AWS Lambda pricing is based on GB-seconds (the amount of memory allocated multiplied by the execution time), these two factors directly inflate monthly cloud bills.

The Solution: GraalVM and Native Images

To solve this, we migrated our serverless workloads to GraalVM.

GraalVM allows us to use Ahead-of-Time (AOT) compilation to convert standard Java applications into highly optimized, standalone native executables.

  • Instant Startup: Native images do not require a JVM to warm up. They start in milliseconds, eliminating the dreaded cold start latency.
  • Minimal Footprint: By analyzing the code at build time and stripping away unused classes and metadata, GraalVM drastically reduces the memory required to run the application.

The Results: Faster, Cheaper, Better

By deploying GraalVM native images to AWS Lambda, we were able to significantly lower the memory allocation for our functions while simultaneously decreasing execution times. This combined reduction in GB-seconds is exactly how we reduced AWS costs by 40% using GraalVM and serverless Java.

Beyond the cost savings, our clients experienced a smoother, faster, and more responsive application, proving that enterprise Java still has a massive role to play in the serverless future.
