8 2. WHAT PYTHON BRINGS TO OPENSTACK Ease of Use & Inclusive Community

9 WHY OPENSTACK CHOSE PYTHON Distro integration Easy to read Easy to learn Easy to patch Ops familiarity

10 WHY OPENSTACK KEPT PYTHON Integration language PyPI ecosystem Easy to read Easy to learn Inclusive community

11 3. WHAT OPENSTACK BRINGS TO PYTHON Funding, Contributors, & Quality

12 EXPERIENCE SOUGHT Cloud / sysadmin / devops Technologies like storage or networking Python

13 OPENSTACK & PYTHON JOBS trends for jobs containing python, openstack, openstack python, storage, network, and virtualization from indeed.com

14 SUPPLY & DEMAND trends of salary index for python and openstack jobs from indeed.com

15 EMPLOYER INDEPENDENCE Community Member Reputation-based Influence Job Mobility

16 INFLUX OF PYTHON DEVELOPERS Converted from Enterprise languages Growing excited about Open Source Joining the Python Community

17 QUALITY Detecting regressions before anyone else

18 23 000

19 Number of test runs in OpenStack on a typical work day
