By Dmitri Zimine, CTO of StackStorm (www.stackstorm.com) SCALE 12x Conference February 22, 2014 Los Angeles, CA VMware has achieved broad usage, with some studies indicating that 80% or more of enterprises now use some VMware products. OpenStack, on the other hand, has quickly become the most important OpenSource community since Linux itself. What’s it like to use OpenStack for virtualization and private cloud? And how does that compare to VMware’s solutions?

OpenStack vs VMware
New tools vs Enterprise Suites
DevOps for Infrastructure .next
• Reliable, repeatable, tested automa2on
• Infrastructure as a code • Good engineering prac2ces
Versioning, TDD, CI, CD, refactoring…
• High efficiency and agility at scale!

New generation of tools
1. OpenSource 2. Support infrastructure as code 3. Leverage social coding
#1. OpenSource
It’s not about “free”: • Control • Agility • Bug? fix it! Feature? Build it! • Share (see “Social)
#2. Infrastructure as code
• Full API for automa2on • Defini2ons and configs in Git • Support TDD, con2nuous integra2on, con2nuous deployment, refactoring…
#3. Social coding
Engage community to create and exchage content
• Boosts produc2vity • Rewards contributors • Fuels #1 and #2

10% OpenStack, Devops, DIY tools, Promise of 10x
90% VMW, Tradi2onal IT, Enterprise Suites
Product needs to change
• OpenStack becomes Enterprise class • More like vSphere • Easier to use
Ease of use… to whom?
Ease of use… to whom?
• Depends – Who you are – What you know – What you trying to do
Ease of use… why?
• It’s not about forcing OpenStack into enterprise – To make 10x more admins busy
• It’s about bringing Devops to enterprise – And gegng 10x efficiency gain

Horses vs Tractors
Horses vs Tractors 1890 -‐ 40-‐50 labor-‐hours required to produce 100 bushels (5 acres) of wheat with gang plow, seeder, harrow, binder, thresher, wagons, and horses
1930 -‐ 15-‐20 labor-‐hours required to produce 100 bushels (5 acres) of wheat with 3-‐bo]om gang plow, tractor, 10-‐foot tandem disk, harrow, 12-‐foot combine, and trucks
Horses vs Tractors

Devops promise?
10x
• Vendors: stop building horse wagons – Because they are “easy to use”
• Sys admins: learn to drive tractors – even if are clumsy: driving is good skill
Products DO need to change
• Power tools for power users • Support Infrastructure.next and devops • VMWare • Cisco, EMC, NetApp, BMC, F5… • Or else…

THE BIGGEST WINNERS: STARS AND SUPER STARS
One machine can do the work of <ifty ordinary men. No machine can do the work of one extraordinary man. -‐ Elbert Hubbard
Automation keeps the best part
• More demanding • More crea2ve • More fun
SUMMARY
Transformation
• Main drivers: efficiency and agility • “Devops” movement shows how to get there • Products will support “devops”, or die • Sys admin job will change – demanding, crea2ve, fun
Winners
• Vendors who got it right • Star and super star sys admins
