Open Source Groovy Deployment Tools

Asgard is a web-based interface developed by Netflix to simplify and automate the deployment and management of applications in Amazon Web Services (AWS). It integrates with tools like Auto Scaling, Elastic Load Balancing, and EC2 to streamline continuous delivery and infrastructure management. Although now deprecated in favor of Spinnaker, Asgard laid the foundation for modern deployment pipelines used at scale.

glu is a model-driven deployment and orchestration platform aimed at automating complex rollouts across fleets of machines. It represents desired system state in a declarative model and coordinates agents to converge reality with that model, handling steps like install, start, verify, and promote. The system provides auditing and versioning of deployments, so operators can trace what changed, when, and why. A central console and APIs allow visualizing the topology, triggering rollouts, and performing controlled actions such as canaries and rolling updates. Under the hood it coordinates distributed nodes, tolerating partial failures while continuing to drive toward the target state. By separating deployment recipes from environment specifics, glu encourages repeatable, testable releases for multi-service stacks.
