57 <p>Cloud-native applications are meant to function "in a world of cloud
58 computing that is ubiquitous and flexible." Applications can be
59 developed on a cloud platform, then deployed to different clouds where
60 supporting software stacks will help them run at scale.</p>

89 <h3>I. Codebase - One codebase tracked in revision control, many deploys</h3>
90 <h3>II. Dependencies - Explicitly declare and isolate dependencies</h3>
91 <h3>III. Config - Store config in the environment</h3>
92 <h3>IV. Backing services - Treat backing services as attached resources</h3>
93 <h3>V. Build, release, run - Strictly separate build and run stages</h3>
94 <h3>VI. Processes - Execute the app as one or more stateless processes</h3>
95 <h3>VII. Port binding - Export services via port binding</h3>
96 <h3>VIII. Concurrency - Scale out via the process model</h3>
97 <h3>IX. Disposability - Maximize robustness with fast startup and graceful shutdown</h3>
98 <h3>X. Dev/prod parity - Keep development and production as similar as possible</h3>
99 <h3>XI. Logs - Treat logs as event streams</h3>
100 <h3>XII. Admin processes - Run admin/management tasks as one-off processes</h3>
