Continuous integration and deployment slots
Connect your favorite version control system to your API App, and automatically deploy commits, making code changes easier than ever. When you move your API to production, run tests against a copy of your app provided by deployment slots. Then redirect traffic to the new version without downtime.
Simple authentication
Your API is just a few clicks away from being secured through Azure Active Directory, social network single sign-on, or OAuth. No code changes are required, and we keep the sign-on SDKs for your services up to date.

On-premises connectivity
Securely connect your API app to your corporate or local network using on-premises connections with enterprise-grade security. Serve APIs to your intranet just as if they were running locally, or connect them to existing internal network resources.

“We use Azure to host our entire infrastructure; from websites and SQL databases to different cloud services. Deploying our APIs, for example, is something that would have been more complex if we had to do it on our own or used another hosting company without these out-of-the-box services.”
David Nydegger, Head of Product at zkipster

"Today, the Iberia Express ecosystem is made up of eight front-end applications, dozens of APIs, and nearly 20 applications that run in the background. Each one of these applications has its own independent lifecycle that permits bug fixes and the development of new functionality in an agile way. This is how Iberia Express continually delivers value to its customers."

"The logic and decision-making behind the PowerApps solution goes much deeper than a simple “hours vs. price” calculation to gain insight. Instead, Economic Callouts rationalizes via API apps (part of Azure App Service) through 11 different internal and external data sources ... Additionally, TransAlta was able to keep their PowerApps solution secure by leveraging Azure Active Directory."
