10. RACKSPACE® HOSTING | WWW.RACKSPACE.COM ! 10! • Cycle time for software is getting shorter! • Continuous delivery is a goal! • Scanning windows are not viable! ! THE PROBLEM 10 "DevOps" is an emerging set of principles, methods and practices for communication, collaboration and integration between software development (application/software engineering) and IT operations (systems administration/ infrastructure) professionals.
11. RACKSPACE® HOSTING | WWW.RACKSPACE.COM ! 11! • Automated software testing! • Automated operational infrastructure! • Automated security testing! THE SOLUTION 11
12. RACKSPACE® HOSTING | WWW.RACKSPACE.COM ! 12! AUTOMATING 12 • Declarative configuration language! • Plain-text configuration in source control! • Fully programmatic, no manual interactions!

14. RACKSPACE® HOSTING | WWW.RACKSPACE.COM ! 14! COOKBOOKS 14 • Most major software packages have cookbooks! • You will have to write your own / customize! • Good place to spend security cycles! - Merge patches upstream for extra points.!
15. RACKSPACE® HOSTING | WWW.RACKSPACE.COM ! 15! GROUPING & TAGGING 15 • Tagging your servers applies the required set of recipes! • A base set of recipes is common! • Each server will have multiple tags set at bootstrap time! Node! Node! Node!
