Commentary: Cloud governance instruments written for one cloud are helpful… for that cloud. Cloud Custodian’s open supply strategy might provide a greater manner.
Stacklet arguably should not exist. The corporate simply launched Stacklet Platform across the open supply challenge Cloud Custodian, however one of many cloud suppliers in all probability ought to have constructed one thing comparable first. Stacklet makes it easy to embrace a coverage/governance as code mannequin to offer real-time coverage enforcement throughout all clouds through detection, notification and remediation, utilizing a easy, declarative language.

Each cloud has this need–a approach to do coverage as code at scale–yet it is Stacklet builders (together with a rising group) that constructed Cloud Custodian. Maybe the explanation why, mentioned Stacklet co-founder and Cloud Custodian creator Kapil Thangavelu, is that particular person distributors are targeted on a relatively slender view of the world. Open supply, against this, “has allowed us to supply many various concepts and use instances from plenty of completely different organizations and in many various contexts.”
Here is that Thangavelu quote in context:
Quite a lot of the suppliers take a really slender view of a given downside area as a result of that is the main focus for a given group. Open supply has allowed us to supply many various concepts and use instances from plenty of completely different organizations and in many various contexts….The problem of simply a single piece of the issue is that you just’re fragmenting the top person with 20 completely different instruments to do 20 various things. And that finally ends up being problematic whenever you truly drive to a holistic transformation of being well-managed.
Remember the fact that Cloud Custodian emerged from work Thangavelu was doing at Capital One, which is an enormous firm with over 50,000 staff and tens of billions in income. It was a laboratory primed to assist Thangavelu “service the completely different wants from completely different teams inside the enterprise: audit, danger, safety, utility groups, strains of enterprise,” he mentioned. That helped make Cloud Custodian extremely helpful inside his enterprise. However only one enterprise.
Open supply elevated the scope and utility of Cloud Custodian past one firm’s wants.
“As we have gotten to open supply, that pool of use instances merely expanded,” he famous. Irrespective of how inventive your product managers, they’re all the time essentially constrained by the wants of the enterprise they’re operating. Against this, Thangavelu continued, “Open supply is the strongest approach to obtain [expanded scope] as a result of your utilization and your customers tackle a wider swath of wants than any given firm has. They symbolize the wants of a big numerous set of pursuits. And so they’re all pulling in numerous instructions.”
This push-and-pull from a rising Cloud Custodian group has made it a useful gizmo for organizations that will have 1000’s and even tens of 1000’s of numerous insurance policies to handle. These completely different organizations can thus iterate on their very own insurance policies whereas collaborating on the core, underlying code to make it higher for everybody.
Not that this open supply strategy is simple.
A query of stability
For the Stacklet group, one of many hardest challenges, Thangavelu famous, is balancing challenge wants towards product wants. “The problem of sustaining a group whereas constructing and going on the tempo I need to go in open supply, whereas constructing a product on the similar time, has been an fascinating conundrum,” he burdened. Why? It seems that firm and group generally have to construct at completely different paces.
Take, for instance, backwards compatibility and operational simplicity, two hallmarks of Cloud Custodian growth. These are generally at odds with group want to construct options in numerous new instructions. Now add the complexity (and energy) of enabling these Cloud Custodian customers to develop into contributors of these options they need, whereas preserving the challenge cohesive. “As a result of in case you have a rising group that feels empowered to contribute [it’s very different from] one the place you are merely managing a product backlog in a extra conventional closed supply trend,” he mentioned, which is what some open supply corporations do.
Sound difficult? It’s, and it is made extra so by additionally making an attempt to juggle a income mannequin that permits Stacklet to make sufficient cash to maintain ongoing, core Cloud Custodian growth with out changing into a proprietary software program firm depending on itself for all innovation. Fortuitously, he concluded, there is a rising sense within the trade that it is essential “to know the open supply software program that enterprises undertake, and to even have some duty for what they’re constructing on high of.” As I’ve written earlier than, Stacklet has carried out a implausible job of encouraging this precise sort of customer-driven innovation. Lengthy might it proceed.
