An open standard for defining cloud native apps.

Open Application Model [OAM] is runtime-agnostic specification that defines cloud native apps by natural and enables creating app-centric platforms where developers focus on code only.

Infrastructure Operators

Open Application Model is highly extensible. It provides modularized design to declare, customize and maintain operational capabilities per app needs.

Overview

Traditional Way

Cloud-native is "Hard"

  1. Developers spend time on infrastructure details instead of apps - ingress, labels, iptables rules, DNS, etc, and learning how the platform is implemented.
  2. Restricted platform capabilities - in-house APIs with opinionated abstractions and implementations, lack of interoperability.
  3. Runtime lock-in - platform is tightly coupled with execution runtime, which heavily impact on how you configure, develop and operate your app.

The OAM Way

An App-centric Approach

  1. Application first - the platform is built around a self-contained app model, where operational characteristics are also part of app definition, free of infrastructure here.
  2. Clarity and extensibility - an open standard to modularize your platform capabilities into reusable pieces, with freedom to bring your own abstractions and implementations.
  3. Runtime agnostic - a consistent experience to deploy and operate your apps across on-prem clusters, cloud providers or even edge devices.

OAM is runtime-agnostic. Read its Purpose and Goals for more background information.
