Initial Situation

A typical IT Corporation

Problem: duplicated efforts

An IT company has a complex

ecosystem.

Different environments,

Technologies

Metodologies

Work groups

Locations

Competitors:

Fully cloudified = Fast to introduce changes.

Lower operating costs = Competitive products.

Organizations

Smaller

Agile

The main idea:

Bring the best of both worlds

ITIL

Good practices to manage IT items

Devops

Integrate operations and development.

• Datamodel easy to

modify.

• Interconnected by API

with the rest of

platforms.

CMDB Applications :

CMDB Key features :

•Fully automatized, no maintenance effort needed.

•Backend destroys and re-creates data daily

Automatization

CMDB Key features :

•Objects have to meet certainpolicies.

• If an objectdoes not meetits policies, a flow could be triggered.

Auditable

CMDB Key features :

• The objectshave :

• lifecycle

• audit rules

• costassociated.

Workflow

Before & After

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.

Benefits:

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.

Case of use:

Migrating DataCenter

To save costs, It was decided

to migrate Data center

location

120 Servers had to be migrated.

from our Alcantarafacility in Madrid

to Boecillo, Valladolid.

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 futuremigrations!

Future

Further integration with automatization tools

New objects, according to user feedback.

Conclussions

New paradigm

Infrastructure as code

Scripting is the new black!

A Devops CMDB:

should integrate within your organization.

It’s not a silver bullet

Information is not important by itself,

but what you can do with it.

User feedback is the key.

As you refine your model,

you will find chances of speed up your bussiness processes.

Devops is an iterating process.

Rather than technical difficulties,

the hardest part is to overtake political considerations.

You need direction support.
