The Access microservice was first introduced in Artifactory 5.4. It runs on the same Apache Tomcat as Artifactory, it is also a Java web application.
The Access microservice handles security operations of the Artifactory Platform. Actions such as logins, REST API authentication, and security configuration changes are all handled by this service. It also manages microservice registration for the rest of the Platform.
This microservice was designed to improve the performance of logins and authentications. It has its own Tomcat maxThreads and database connection pool.
