User Management application provides access management functionality to the security solution set of Ericsson Network Manager (ENM). The application provides management of ENM users, allocation of roles, management of passwords etc. ENM is structurally divided as Presentation, Service & Data layers.
The Presentation layer comprises of proprietary ui-sdk framework core which is a collection of multiple apps and frameworks like Backbone, Handlebars, Sinon.JS, Chai.JS, Mocha, Expect.JS, Assert.JS, Less, Jasmine.JS, Node.JS, JSCoverage etc. ENM client applications are developed based on ui-sdk core library and extended using Asynchronous module definition (AMD) JavaScript, HTML and Less.
The Service layer comprises of JBoss clusters and service groups spun up on a Kernel Virtual Machine (KVM). Each service rpm is deployed in a service group contains Ericsson proprietary pre-built core services which can be extended using Java JEE, JAX RS, JPA, EJB, Arquillian, Maven etc.
The Data layer comprises of Versant - Data Persistence Service (DPS), proprietary DPS wrappers & APIs.
