Formal Verification of Orchestration Templates for Reliable Deployment with OpenStack Heat

Abstract

In the context of Network Functions Virtualization (NFV), telecommunication systems are more and more deployed on the cloud, using orchestration engines such as OpenStack Heat. Heat takes as input templates that describe the components of the target system and automatically performs the deployment. This prevents consumers of cloud services from handling the challenges of manual deployment. However, deploying such systems remains challenging. Indeed, the templates given to Heat may contain errors that can lead to a failed or a partial deployment, thus compromising the systems reliability. To handle this challenge, we propose a formal approach and a tool for the verification of templates consistency prior to launching their deployment. A case study is presented to validate the approach.

In-Depth Analysis of Kubernetes Manifest Verification Tools for Robust CNF Deployment

“…Finally, our verification tool under development will be in line with the implementation methodology carried out in [36], [37]. These studies used Alloy [28] to formally verify different types of manifests, such as Docker Compose and OpenStack Heat languages.…”
