DevOps is not a Race

Most of what we read about or hear about in DevOps emphases speed. Continuous Deployment. Fast feedback. Fail fast, fail often.

How many times do we have to hear about how many times Amazon or Facebook or Netflix or Etsy deploy changes every day or every hour or every minute?
 
 
 
 
 
 

Even enterprise DevOps conferences are about speed and more speed.

Speed is Sexy, but…

Speed is sexy. Speed sells. But speed isn’t the point.

Go back to John Allspaw’s early work at Flickr, which helped kick off DevOps. Actually, look at all of Allspaw’s work. Most of it is about minimizing the operational and technical risk of change. Minimizing the chance of making mistakes. Minimizing the impact of mistakes. Minimizing the time needed to detect, understand and recover from mistakes. Learning from mistakes when they happen and improving so that you don’t make the same kind of mistakes again or so that you can catch them and fix them quicker. Breaking down silos between dev and ops so that they can work together to solve problems.

La de da, everything’s fine … change happens….OMGWTF OUTAGES!!!!!

Infrastructure as Code and eliminating snowflake servers. Not about maximizing speed.

Checking everything into version control – code, application configuration, server and network configurations… not about maximizing speed.

Breaking releases down into small change sets with fewer moving parts and fewer dependencies, makes changes easier to understand, easier to review, easier to test, simpler and easier to deploy and simpler and easier to roll-back or fix. This is not about maximizing speed.

Executing automated tests in Continuous Integration…

Building out test environments to match production so that developers can test and learn how their system will work under real-world conditions…

Building automated integration and deployment pipelines to test and to production so that you can push out a change or a fix immediately is…

Change controls based on transparency and peer reviews and repeatable automated controls instead of CCB meetings…

Auditing all of this so that you know what was changed by who and when…

Developers talking to ops and learning and caring about run-time infrastructure and operations procedures….

Ops talking to developers and learning and caring about the application and how it is built and deployed and configured…

Wiring monitoring and metrics and alerting into the system from the beginning…

Running game days and testing your incident response capabilities with developers and ops…

Dev and ops working through Root Cause(s) Analysis in blameless post-mortems when something goes wrong so that they can learn and improve together…

Injecting automated security testing and checks into your build and deployment chain…

None of this is about speed. It is about building better communications paths and feedback loops between the business and developers and operations. About building a safe, open culture where people can confront mistakes and learn from them together. About building a repeatable, reliable deployment capability. Building better, more resilient software and a better, more resilient and responsive IT delivery and support organization.

DevOps is not a Race

Ignore the vendors who tell you that their latest “DevOps solution” will make your enterprise faster.

And unless you actually are an online consumer startup, ignore the hype about the Lean Startup and Continuous Deployment – this has nothing to do with running an enterprise.

DevOps is a lot of work. Don’t go into it thinking that it’s a race.
