Editor's Notes
- #2 Copyright Einar & Partners Architecutre : 360 view of the architecture, available capabilities and application inventory Service : how we offer, consume and market services from a technical and business perspective Operations : what éléments make up the backbone of the services the organization delivers? Another to represent the CSDM frameowork is to use layers. The first CSDM layer is the architectural layer, it’s pretty much the same as the CSDM design domain. Carré de sable des architectes. Défini ton inventaire d’application d’affaires et les capacités d’affaires pour atteindre les objectifs stratégies de l’organisation. Then we have the service layer, it is everything about the services that we deliver to our consumers – be it customers or end users, so this is where we document business and technical services as well as their offerings and commitments Then we have the operational layer – this is where our configuration items reside but also the application service + definition de application service The application service has no commitments and no offerings but they rather bring together borth worlds of the services world and the operational world. They are the bridge that we are looking for bridging services and operations. Because bridging services and ops is that this is all about right? A business needs to know whatt exactyly is impacted – if there is for example an outage or security vulnerability Application CI : - On a web server that we are using for our internet application, we might have three verions of tomcat installed. But we don,t know which one of these tomcat installation is now used in our application service, thereforware we have application CI, its an instance of the software that is running on a device, so occupying memory space and it is part of an application service
- #3 represents a standard and shared set of service-related definitions across our products and platform that will enable and support true service level reporting while providing prescriptive guidance on service modeling within the CMDB. These service-related definitions span the ServiceNow® product portfolio and the Now Platform ServiceNow products are standardizing their use of data from the CMDB. That standard is the CSDM which identifies where to place service and application related data within the CMDB. Current and future products from ServiceNow that utilize the CMDB may require data to be found in the CMDB framework identified within this white paper. Without CI data in these prescribed CMDB tables, you may not receive the full value of the ServiceNow platform. This very conceptual and will require and separate workshop to discuss how to model your data.
- #4 This is the mapping of the conceptual entities on the CSDM to the actual table structure within Service Now. Note that in most cases the mapping is straightforward, but in some cases the names of the tables may not map to the CSDM conceptual model. Application is one notable area where there are many types of Application Services under the hood. The complexity is now managed in the CSDM navigator with a new Application Service Wizard to help create and manage them, hiding this complexity. Infrastructure CI’s map to many tables and class structures. These are dependent on the data sources, discovery, and integrations from the element managers that are often implemented. The prescribed relationships are also shown to help understand how these entities are related. The references are for the most part parent / child. The CSDM navigator exposes the exact relationships expected to related entities. One more thing that we wanted to show, and well have this in the lab. Many folks feel that the only way to show a dependency view in the dependency map is having relationships between the various Cls. Its actually possible to show dependencies using references, not just relationships. So in several scenarios, when we relate a service offering to its parent service, were not actually using a relationship. There's an attribute that exists that's parent. We'll walk through that here in the lab. But this allows you to show those dependencies in the dependency view without having to create a relationship
