What makes dev2ops so hard anyway?


Alex Honor / 

Migrating application changes from development to production was simpler when systems were centralized, target environments homogeneous, and the whole process needed little or no automation. But today’s business applications have evolved to run 24/7, use distributed architectures, are hosted in multiple environments and the process to change them has become increasingly more complicated and very hard to automate.

I have noticed several factors that add up to making dev2ops technically very challenging in both large and small organizations:

  • Rate of change: Many businesses depend on driving change from development, through test environments and on to production operation, on a daily basis (sometimes even more!). Worse yet, some things need to change faster than others. For example, content and data need to change constantly while core technologies like platforms less frequently. No matter what, the business desires the ability to update any and all parts of the application when needed. Can this be done predictably and reliably?
  • Nature of change: What comprises application change varies, too: data, code, configuration, content, platforms. Each kind of change, has a different impact on the overall stability of the application. Does the organization understand change is not created equally?
  • Complexity: Applications supported by distributed architectures and multiple hosting environments do not present a simple interface to widespread nor pinpoint modification. Understanding how to make changes at each point and then figuring out a sane way of coordinating change across the board is tricky. Who knows what connects to what and the best way to change the application over time?
  • Organizational boundaries: Who performs dev2ops? Developers, operations, both or other? The application development is carried out by developers so are they best suited to install it and set it up in a production environment? Operations understands how to maintain and scale infrastructure so should they take apart the application and deploy it the way they best see fit?

Reflecting on these challenges organizations face, it’s amazing that the dev2ops process works at all! In the end, its accomplishment usually falls on a few dedicated, knowledgable individuals, working long, intense hours at the worst times (ie, late nights and weekends).


Does dev2ops have to be an “all hands on deck” scenario or can best practice and better tools bring efficiencies and reliability?

    This is an interesting list. I think that few people have realized that the shift from a development-centric packaged software world to a dynamic operations-centric software as a service world has created a whole new set of problems that need to be solved.
