The `ha-singleton-deployment` quickstart demonstrates the recommended way to deploy any service packaged in an application archive as a cluster-wide singleton.

== What is it?

The `ha-singleton-deployment` quickstart demonstrates the deployment of a service packaged in an application as a cluster-wide singleton using singleton deployments.
In this example, the service is a timer that is initialized by a `@Startup @Singleton` bean.
The example is built and packaged as a single EJB archive.
In this example, the service is a timer that is initialized by a `@Startup @Singleton` Jakarta Enterprise Beans bean.
The example is built and packaged as a single web archive.

For more information about singleton deployments, see _HA Singleton Deployments_ in the {LinkDevelopmentGuide}[__{DevelopmentBookName}__] for {DocInfoProductName} located on the Red Hat Customer Portal.
