Moving AWS Code from LocalStack to Spinifex: What Changes in Production

Developers whose Terraform and boto3 tests pass against emulators like LocalStack or Moto can move the same code to Spinifex, an AWS-compatible cloud running on their own servers. Only the endpoint, credentials and TLS settings need to change, and resources such as EC2 instances then boot as real virtual machines and persist until deleted. Spinifex implements a narrower set of services, including EC2, S3, IAM and EKS, but omits Lambda, DynamoDB, SQS and SNS. Unlike emulators, it splits traffic across a TLS gateway on port 9999 and an S3 endpoint on port 8443, and it enforces IAM policies and security groups on every request. The guide includes example Terraform provider configuration and notes that Spinifex generates its own certificate authority at install time.
