Who is this presentation for?

  • DevOps and microservices practitioners



Prerequisite knowledge

  • Basic software engineering and cloud engineering experience

What you'll learn

  • Understand the realities of building microservices architecture applications in a large organization
  • Explore the cultural shifts required when teams (of any size) embark upon something as transformational as new architectural paradigms (microservices specifically)
  • Discover lessons Capital One learned


Despite its success in building an engineering and DevOps culture, when Capital One embarked on the gargantuan task of embracing microservices several years ago, it had to do an analysis of which of its development and operational practices were applicable to the new architectural style and which had to be fundamentally reevaluated. Irakli Nadareishvili shares lessons learned from the process.

Topics include:

  • How much of “let a thousand flowers bloom” is appropriate?
  • What does “you build it, you own it” specifically mean for an organization of thousands of engineers and hundreds of critical applications?
  • Where are the efficient lines of separation between centralization and federation?
  • A fundamental rethinking of deployment models from DevOps to new architectural capabilities
  • A cultural shift: What are traditional software development roles in the new reality?
  • Changes in tooling
  • Pragmatic approaches to heterogeneity: How much freedom is enough?

Can you publish your slide please? I am looking for a devop recommendation.

I have multiple loosely couple micro services such that sometime commit on multiple repo needs to go in together. It is in the form of all or nothing. What tool do you recommend for this. (We are using repo tool and gerrit)
