BIT.Group presents an approach to automating the provisioning of SAP systems using CloudStack for infrastructure management and Ansible for configuration automation. This allows setting up a full SAP stack including virtual infrastructure, storage, operating system and SAP installation in a short and standardized manner. Key benefits are reduced time to deploy systems, consistent configurations with lower operations effort and higher quality. Lessons learned include the different worlds of infrastructure automation versus application provisioning.

APACHE CLOUDSTACK @ BIT
ACS@
BIT
• Why are we using CloudStack?
• evaluated a few cloud management platforms
• scope: free, easy to use, multi-tenancy also for administration
• Learned lessons:
• works for small operation teams
• easy to upgrade – in 30 minutes
• active community

CEPH STORAGE
Ceph
• Distributed storage system
• Run‘s on commodity hardware
• Selfhealing
• OpenSource
• CloudStack integration
• Lessons learned:
• previous storage system was too unflexible
• cloud environments need to scale online
• no downtime for maintenance
• hard disk failure over easter weekend – monitoring works, disk
change later

SAP INSTALLATION AUTOMATION
SAP
• Complex installations in many variations
• Time consuming – large install files
• Pro and Con – Templates vs. Scripting
• Templates:
• faster to deploy
• much effort to maintain
• unflexible, high storage usage
• Automation:
• very adaptive
• installation takes time
• XML file based unattended automation replace wizard
• Adaption of XML with hostname, SID, …
