To build and deploy the Lambda Layers, we run a pipeline with the following steps:

* We fetch the latest PyPi release and use it as the source for our layer.
* We build Python versions ranging from **3.9 to 3.13** for x86_64 and arm64 architectures. This is necessary because we use pre-compiled libraries like **Pydantic** and **Cryptography**, which require specific Python versions for each layer.
* We build Python versions ranging from **3.9 to 3.14** for x86_64 and arm64 architectures. This is necessary because we use pre-compiled libraries like **Pydantic** and **Cryptography**, which require specific Python versions for each layer.
* We provide layer distributions for both the **x86_64** and **arm64** architectures.
* For each Python version, we create a single CDK package containing both x86_64 and arm64 assets to optimize deployment performance.

???+ warning "GLIBC Version Mismatch"
Compiled libraries built on systems with newer GLIBC versions will fail on Lambda runtimes with older GLIBC versions. Ubuntu 24.04 (GLIBC 2.39) and Ubuntu 22.04 (GLIBC 2.35) are incompatible with Lambda python3.11 and earlier (GLIBC 2.26). Always use `--platform` flags or Docker with Lambda base images.
