EFS (Elastic File System) is AWS's managed NFS service. Lambda mounts EFS volumes directly, eliminating the git-on-S3 clone/push cycle. Git repos live on a persistent filesystem — Lambda reads/writes them in place, just like a VPS. Combined with AWS's managed service catalog (Bedrock, SQS, DynamoDB, CloudFront, ACM) and first-class Pulumi support, this is the strongest fit.
