DCML/ITIL/CMDB Use Cases

• Ajay Gummadi

2
Problem

• Software Vendor VendorCo, requests for an audit
  of Customer CustomerCos usage of its server
  based application ServApp.
• VendorCo claims that CustomerCo currently uses
  more licenses than purchased and hence should
  purchase more licenses.
• Use Case UC002 at http//dcml.blogspot.com/

3
CustomerCo

• CIO of CustomerCo is IT/best-practices savvy
• CIO has implemented DCML and ITIL in the
  organization over a year ago
• CMDB reflects the current state of the
  organization

4
DCML Architecture
5
Step 1

• VendorCo requests an audit
• Requests a list of all instances of ServApp,
  running on BSD
• Request made via DCML DIX format.

14
Step 8 Verification of keys

• DCML Processor verifies each license key against
  CMDB and DSL
• License keys are also checked against invoices
  and receipts (available via CMDB)
• DCML Processor seeks clarification from DCML
  agents and users via DCML DIX and auto-generated
  XUL/XForms forms
• CMDB is updated, with findings.

15
Step 9 Completion of Audit

• DCML Processor generates audit reports
• Internal workflow engine routes report to CIO for
  approval and digital signatures
• Approved report is dispatched to VendorCo, in DIX
  format.

16
Step 10 Post Audit Assessment

• CIO has data regarding ServApp usage
• CIO can negotiate better pricing for licenses,
  using data available from DCML/CMDB
• CIO can reallocate unused/sparingly used
  licenses.
• CIO can minimize/eliminate upgrade fees for
  unused (but installed) instances.

17
Advantages

• Accuracy of information
• Real-time updates
• Quicker turnarounds
• Cost savings
• BSA/SIIA compliance

18
Advantages (contd)

• Reports Display by cost center/department/site
• Resellers can bid, based on internal usage data
  (DCML/CMDB PartnerNet)
• Powerful reporting (includes historical data)
