Kubernetes has become the leading container orchestration environment. Its success has driven the remarkable growth of Kubernetes services on every public cloud. However, the core resources in Kubernetes like Services and Deployments represent disparate pieces of an overall application. They do not represent the application itself. Likewise, objects like Helm charts represent a potentially deployable application, but once deployed there’s no application-centric model of the running application. This need to have a well-defined and coherent model that represents the complete application, not just its template and/or its constituent pieces, is why Microsoft and Alibaba Cloud have created the Open Application Model (OAM) project under the Open Web Foundation.
