DevOps and the software revolution

Avishai Ish-Shalom (@nukemberg)

Creative Destruction

Lifespan of giant enterprises is shrinking:

Software is eating the world

- Marc Andreesen, 2011

• Amazon - largest retailer
• Google - largest ad & marketing
• AirBnB - largest hotel chain
• Uber - largest taxi company
• Skype - largest intl telecom
• LinkedIn - largest recruitment agency

Many more

Traditional work

SW revolution

Why now?

• Computers everywhere
• Mobile devices
• The internet
• Robots

In a world where every device has an API

Everything is a software problem

If you go to bed tonight as an industrial company, you're going to wake up a software company.

The world changed.

 

- Jeffrey Immelt,

   General Electric CEO,

   2014

One problem

Our organizations were not designed for SW

Software is

• Flexible
• Upgradable
• Replicable
• Cheap
• Rapid development

SW development is a learning process

• Feedback loops
• Experimentation

The mythical man month

- Fred Brooks, 1975

• Small teams
• Cross functional teams
• Deliver early
• Flexible organizational structure

The Agile manifesto

- Published 2001, origins ~ 1996

• Small increments
• Client focus
• Reacting to change
• Learning cycles
• Code over documents

Open source!!!

• Modifiable
• Upgradable
• Fixable
• Understandable
• Readily available

Meanwhile, in traditional IT...

Standard enterprise IT

• Manual work
• Tech silos
• Blackboxes
• External vendors
• Monoliths
• Devs isolated from production
• Process heavy

What if I told you

There is no NOC?

You build it, you run it

- Werner Vogels,

  Amazon CTO, 2006

• Circa 2002 - Amazon enforces an "API only" rule, no other communications between teams is allowed
• Devs run all services

Built in resiliency

- Netflix, 2010

• Inject faults into production
• Applications must survive without business impact
• H/A over unreliable infra
• Automatic recovery

SDx

Software defined everything

Agile infrastructure

- Andrew Clay-Shafer,

  Puppetlabs co-founder, 2008

• SW development methodologies for IT
• Infra should be SW managed
• Rapid, agile development of infra

The Cloud

Is just a set of APIs

• Self service
• Shared resources
• Software defined
• Generic
• Comodity

Nobody cares about HW anymore

• Abstracted away
• Automated
• Commodity
• Leased

10+ deploys per day

- John Allspaw, Flickr, 2009

Continuous deployment

• Every commit automatically deployed to production
• Automatic Q/A only
• Devs write tests
• Devs & Ops working together

DevOps

Agile system administration

- Patrick Debois, 2008

• Organizes the 1st DevOpsDays
• Accidentally coins the term "DevOps"
• 1st DevOpsDays spawns a movement to reform IT

DevOps is culture & methodologies

• Agile system administration
• Infrastructure as code
• Align responsibility with control
• Enhance feedback loops
• Visibility, communication, trust

Break the silos!!!!
