Kapil Thangavelu: Like so many giant enterprises eight years in the past, they had been aggressively transferring to the cloud and open supply, and the mandate was to speed up all of the builders entering into the cloud setting. Clearly being in monetary companies, we had been coping with a extremely regulated trade — each new cloud service needed to have its certs signed off, every thing configured appropriately in REST. There have been a ton of one-off scripts, it was simple to configure issues incorrectly and create backlogs of issues, and you then had the opposite challenges of creating positive issues had been examined and monitored constantly. It was apparent that this was not going to scale throughout a whole lot of of engineers and software groups. So we stated, let’s create a DSL that may deal with these points holistically throughout these dimensions. Let’s not simply determine cloud issues, however determine a language that will additionally allow us to repair them in real-time. We designed Cloud Custodian to be a extremely readable YAML DSL. We needed this language and coverage definition for cloud assets to be accessible throughout many alternative teams, to builders, to their managers, and even to the auditors in secondary traces like safety. And we needed it to be extremely readable, as a result of in coding you’re all the time going to be studying rather more than you write with cloud assets, so let’s make it as readable as doable.

Van: What would you say Cloud Custodian is understood for at the moment, by way of the sorts of issues it solves?

Thangavelu: The preliminary focuses had been tagging, compliance, safety, but in addition doing workflows round price stuff. Cloud Custodian offers you a workflow the place you’ll be able to outline issues like grace intervals for cloud assets the place they then shut off if unused — these sorts of constructs for constructing logical workflows round cloud assets, as insurance policies. Even at the moment, eight years after open sourcing the undertaking in 2016, Cloud Custodian’s declare to fame is being finest in school in remediation. It doesn’t simply allow you to admire issues, it’s designed that can assist you clear up the issues in your cloud footprint. The massive areas the place it thrives are issues like rubbish assortment and coping with under-utilized cloud assets, right-sizing assets which may be overprovisioned, dealing with the life cycle of objects and buckets and all of the reclamation insurance policies that go together with that, and ensuring configurations are consistent with the specified insurance policies, pre-deployment. These are among the huge areas, however Cloud Custodian additionally has issues like blast radius safety and different sorts of tooling to assist take care of the dangers of remediation in manufacturing, which is all the time tough.
