Azure Kubernetes Service will not prevent you from deploying an application containing scheduled tasks internally. If you have any question, please send me an email. When a HTTP request comes (from a browser, a web service client, an HttpInvoker or an AJAX application Spring doesnt care), it will go through a chain of filters for authentication and authorization purposes. It comes with a JpaRepository interface which defines methods for all the CRUD operations on the entity, and a default implementation of JpaRepository called SimpleJpaRepository. If any of the Spring Boot applications require authentication or authorization, ensure they're configured to access the identity provider: If your application requires non-volatile storage, configure one or more Persistent Volumes. The @Controller annotation is used to define a controller and the @ResponseBody annotation is used to indicate that the return value of a method should be used as the response body of the request.
