Paper related to WP6 work of TREDISEC.
In this work, we propose AURA, a cloud deployment tool used to deploy applications over providers that tend to present transient failures. The complexity of modern cloud environments imparts an error-prone behavior during the deployment phase of an application, something that hinders automation and magnifies costs both in terms of time and money. To overcome this challenge, we propose AURA, a framework that formulates an application deployment as a Directed Acyclic Graph traversal and re-executes the parts of the graph that failed. AURA achieves to execute any deployment script that updates filesystem related resources in an idempotent manner through the adoption of a layered filesystem technique.
In our demonstration, we allow users to describe, deploy and monitor applications through a comprehensive UI and showcase AURA’s ability to overcome transient failures, even in the most unstable environments.
