18. Before & After

19. Benefits:
We have found underused resources
that can be freed to save money.
We can set standard quality controls
for any given inventory item.
 Also, we deliver adquired knowledge
to the users, the current state of their
resources and its cost for the
company.

20. Benefits
 We, the sysadmins, are
no longer a
grandmother cooking
recipes.
 We are turning into
cloud service providers
for the organization.
 Thanks to the ansible
integration we can
automatize the
management of our
infraestructure.

21. Case of use:
Migrating DataCenter
To save costs,
It was decided
to migrate
Data center
location
120 Servers
had to be
migrated.
from our
Alcantara
facility in
Madrid
to Boecillo,
Valladolid.

22. Case of use: Migrating DataCenter
We used the CMDB for:
 Verify connectivity and credentials for the
servers.
 Backup server configuration.
 Verify the migrated servers were covered by
third parties support.
 Arrange shutdown of the servers
 Keep in touch with the owners of the servers.
 Verify special network config for the servers.
NAT, publishing domains, etc.
 Those scripts could be reused for future
migrations!

23. Future

24. Future
Further integration with
automatization tools
New objects, according
to user feedback.

25. Conclussions

26. New paradigm
Infrastructure as code
Scripting is the new black!

27. A Devops CMDB:
should integrate within your
organization.
It’s not a silver bullet

28. Information is not important by
itself,
but what you can do with it.
User feedback is the key.

29. As you refine your model,
you will find chances of speed up
your bussiness processes.
Devops is an iterating process.

30. Rather than technical difficulties,
the hardest part is to overtake
political considerations.
You need direction support.
