DevOps: Now and to the Future

DevOps: Now and to the Future

It’s been a decade of devops, how has it shaped our industry and where are we going next? In this talk, we’ll take a look at the evolution of software tools and impact on devops in the last 10 years and our path to the future. We’ll cover key skills and practices that are the bedrock to effective devops within organizations.

Topics include:

* DevOps and SRE, what’s the difference?
* Do we need DevOps with Serverless?
* How do security, testers, and other engineers impact devops?
