Multi-Language Infrastructure as Code

We all use programming languages to write expressive, reusable, and powerful application code, with flourishing open source communities, and a bit of fun. One domain that has not yet experienced the same, however, is cloud infrastructure and operations. Most engineers in this domain still use JSON, YAML, DSLs, or bespoke templating solutions, that lack most of what we know and love about general purpose programming languages. Not anymore!

In this talk, we’ll see how a multi-language approach to infrastructure as code, using general purpose programming languages, lets cloud engineers of all backgrounds program AWS, Azure, Google Cloud, and Kubernetes infrastructure, unlocking the same software engineering techniques we commonly use for applications: abstractions and reuse, expressive control structures, package managers, testing, and IDEs, to name a few. The result is a serious boost to productivity, flexibility, and safety -- and a practice we like to call programming the cloud.
