CloudCaptain, a product of InfrastructureX GmbH, provides tools for deploying JVM, Node.js, and Go applications to AWS using immutable infrastructure. Its platform builds minimal, fully provisioned application images in seconds, designed to boot directly on virtual hardware without a traditional operating system or container runtime. Images can be tested locally with VirtualBox and deployed consistently to AWS, helping keep instances identical across environments.

The service integrates with frameworks and technologies including Spring Boot, JHipster, Grails, Dropwizard, Play, Tomcat, Node.js, Go, and Revel. It offers command-line tools and Maven and Gradle plugins for generating, testing, and deploying images through build workflows. CloudCaptain Vault provides an online repository for storing images, supporting continuous delivery pipelines.

For AWS deployments, CloudCaptain automates atomic blue/green releases using Elastic IPs or Elastic Load Balancers. New versions enter service only after passing configured health checks, enabling zero-downtime updates. The company also offers Sprinters, a product that runs GitHub Actions jobs on AWS, advertised as up to ten times cheaper with a one-line workflow change.
