21. App Service Java

22. Fully managed PaaS for Tomcat and JBoss EAP
Focus on the apps that run your business, not managing infrastructure
Deploy JAR, WAR or EAR using tools of your choice
Built-in CI/CD with zero downtime deployments
Intelligent troubleshooting and performance optimization
Automatic updates and security patches
App Service

23. Deploy code or a
container
Deploy your application code to a container that Azure
manages for you, or pull your own container from a
registry.
We provide APIs, plugins, and extensions to deploy from
the Azure CLI, IntelliJ, Eclipse, VS Code, Maven, GitHub
Actions, Azure DevOps Pipelines …. and more!
App Service Deployment Slots are independent staging
environments where you can safely deploy new versions of
your app or configuration changes. When your changes are
ready, swap the new version or config into production. App
Service will scale the staging environment to match your
production footprint before routing traffic to the new
environment.

25. Scale your deployment
With App Service you can scale your web apps horizontally
based on resource utilization, request count, or simply by
time-of-day.
Your configuration is applied to each container as they
come up, so the instances are identical.

26. Monitor your apps
Azure Monitor Application Insights is the Azure-native
application performance monitoring (APM) service. Monitor
your Java, Node.js, and .NET apps on App Service—no code
changes required.
Watch live metrics, user journeys, or an application map of
your entire deployment. Set up alerts for slow or failing
requests and use App Insights to solve and diagnose the
issue.

27. All Java apps welcome
Embedded Server, Tomcat, and Java EE / Jakarta EE
MicroProfile
Quarkus and more!
Helidon
Java SE Apache Tomcat Jakarta EE

28. JAR Deployment
• Java 8, 11, 17 available. Future Java LTS versions
will be available on App Service as they are
released
• Apply minor version updates automatically or on
your own terms
• Deploy your fat JAR apps with DevOps Pipelines,
Maven plugins, GitHub Actions, or the Azure CLI
Spring Boot Microprofile
Quarkus and more!
If it runs as a JAR, it can run on App Service

29. Migrate your Tomcat
apps
• Tomcat 8.5, 9.0, 10.0 available on Java 8, 11, 17
• Deployment APIs unpack your WAR apps when
scaled horizontally
• The Migration Assistant is a standalone tool for
discovering, assessing, and migrating web
applications
• Migrate Tomcat Java apps on Windows servers or
Linux servers
• Available for download at http://aka.ms/appmigrate

30. Jointly supported
JBoss EAP on Azure App Service is a jointly developed,
managed, and supported service. This means you can
submit a support case with either company, and behind the
scenes Azure and Red Hat will collaborate to resolve your
question or issue.
You get best-in-class support from Red Hat and Azure, for
the entire stack… all without any external licenses or
subscriptions! Expect a single, simple bill from Azure.
All JBoss EAP sites on App Service are automatically
enrolled in the joint support program.
