The official documentation site for Open Application Model (OAM).
Open Application Model (OAM) is a runtime-agnostic model for defining cloud native applications. Focused on application rather than container or orchestrator, Open Application Model brings modular, extensible, and portable design for modeling application deployment with consistent higher level API. This is the key to enable simple yet robust application delivery workflow across hybrid environments including Kubernetes, cloud, or even IoT devices.
"Developers think in terms of application architecture, not of infrastructure."
In today's hybrid deployment environments, managing applications without application context is hard:
- Developers spend time on infrastructure details instead of apps - ingress, labels, DNS, etc, and learning how the infrastructure is implemented.
- Inextensible - upper layer abstraction may be introduced, but it's almost certain that the needs of your app will outgrow the capabilities of that abstraction soon.
- Runtime lock-in - app description is tightly coupled with the runtime infrastructure, which heavily impact on how you configure, develop and operate the app across hybrid environments.
In Open Application Model, we propose an app-centric approach instead:
- Application first - define the app with a self-contained model, where operational behaviors as part of app definition, free of infrastructure here.
- Clarity and extensibility - an open standard to modularize infrastructure capabilities into reusable pieces that adapts to your needs, not the other way around.
- Runtime agnostic - a consistent experience to deploy and operate your apps across on-prem clusters, cloud providers or even edge devices.
In real world, Open Application Model is the theoretical model behind KubeVela project - a modern application deployment platform that intends to make delivering and managing applications across today's hybrid, multi-cloud environments easier and faster.
The model itself is driven by KubeVela project and maintained as a set of versioned API documentations as shown below.
