The document discusses the use of OpenNebula to improve data center operations through automation and self-service capabilities. It highlights the challenges of traditional data centers, such as the lack of APIs and automation, and presents use cases showcasing how OpenNebula can streamline the deployment of virtual machines. The author emphasizes the need for a change in the consumption model and outlines specific technologies and integrations that enhance efficiency in managing workloads.

4. HOW A CLASSIC DATACENTER
LOOKS LIKE
IMAGINE

6. WHAT DO YOU THINK IS MISSING
(OR THE CHALLENGE)?

7. NO SELF SERVICE

8. NO API

9. NO AUTOMATION

10. WHAT DOES THE USER WANT?

11. A useable server or VM.
“Actually“, simple – isn‘t it?
NOT MUCH, ACTUALLY

12. WHAT'S THE CHALLENGE?

13. THIS (OR SIMILAR) IS HOW ONE CAN IMAGINE A DATA CENTER
Complex, a lot of systems (parts), bare base components
Analogy: car to server/VM:
“All I want to do is drive!“

14. There is often a lack of automation and
simpler, faster deployment.
What was that with „on-demand“
(or self-service and API`s in the age of the cloud)?
IN BRIEF

15. WHAT DO WE NEED TO
CHANGE?

16. THE CONSUMPTION MODEL!

17. Abstraction / Orchestration (IaaS)
In-Guest Automation – „ready VM“
Integration via Hooks
VM Workloads / DevOps / CI-CD
Virtual Datacenter (VDC)
cloud.company.com
• Self-Service • API
Consume:
• ready VM
O n - P r e m
Governance:
• Ressources
• Location
• Cost
Central Auth via AD
• Auth
• User / Group
VDC = How IT is consumed
• Shares and slices IT
Make IT Infrastructure „invisible“
• Abstract IT Infrastructure
• „VM everywhere“

PROCESS : „NEW VM“

20. SOME INSIGHTS INTO OUR
PROJECTS

21. USE CASE #1
Simply Deploy VMs
Technologies / Components:
OpenNebula + VMware
Power Shell Domainjoin

22. BEFORE OPENNEBULA
create VM
install
OS
config
OS
- Login to vSphere
- Create emtpy VM
- Configure VM
- Mount ISO to VM
- Start VM
- Go to VM console
- OS Installation
Configure:
- Network
- Hostname
- (domain join)
…
takes about 15 minutes

23. WITH OPEN NEBULA
Instantiate VM
- Login to Open Nebula
- Choose Template
- Press „Instantiate“
Takes about 1-2 minutes to the ready VM!

24. USE CASE #2
CI / CD PIPELINE
Technologies / Components:
OpenNebula + vCenter + MS Azure
Terraform
Ansible & AWX
Jenkins
Git

25. FROM WORKSHOP...

26. IT WORKS – THANKS TO OPENNEBULA HOOKS
... TO THE FINAL SOLUTION
SHORT LIVE-DEMO IS POSSIBLE J

27. USE CASE #3
REPLACE VCLOUD
Technologies / Components:
• OpenNebula + KVM
• Many Hooks (ServiceNow, CheckMK,...)
• VDC /User Provisioning via XMLRPC
• VXLAN with BGP-EVPN for Fenced Nets

28. • Extended Network Model for OpenNebula (VXLAN EVPN)
• Some really interesting “Fund a Feature“ Requests
• A 100% Replacement of VCD with ONE + KVM (!)
OUTCOMES USE-CASE #3

29. WHY ?

30. WELL..., THERE ARE MANY REASONS

31. LACK OF COMPLEXITY

32. ABILITY TO INTEGRATE

33. MATURITY

34. BUT: THERE ARE OTHER REASONS
CAN YOU IMAGINE?

35. EXCELLENT PARTNERS
THANK YOU, OPENNEBULA TEAM!!!
