Project Kratos: AWS Lambda functionality, without Amazon lock-in

Project Kratos uses Docker as part of a self-managing, stateless application stack, but it'll be a commercial product rather than an exclusively open source creation

Amazon AWS Lambda's premise is audacious: event-driven applications made of little more than pure functions in Python, Java, or Node.js., creator of a task-queuing platform that runs across multiple clouds, is preparing a similar platform that runs on any cloud or local architecture and uses Docker containers as the basic unit of the service.

Project Kratos, as it's called, allows enterprises to take either existing AWS Lambda functions or Dockerized workloads and deploy them in a stateless fashion. A "runner agent" cluster listens for work queued up by way of's RESTful API. The agent cluster stores metadata about the job --whether it completed successfully, how to deal with retrying failed jobs -- but all other state data has to be manually managed by the applications themselves.

While Kratos and make use of some open source projects, the core of Kratos is not intended to be open source. Given that part of's pitch is avoiding lock-in with services like AWS Lambda, that approach seems counterintuitive. Instead, the company plans on offering its protocols as an open project, with possibly some other open source elements to follow.

"We don't have much of an interest in becoming a support and services company," said CEO and co-founder Chad Arimura in a phone interview, citing how most outfits based on open source tend to turn into such things. "Enterprises want an open source story, but they don't want to rely on just open source software. They want a commercial offering as a complement, which they can trust running this stuff."

The company's success with its existing customers, Arimura said, means there's been little momentum to become open source. "We want to put investment money into the product and the platform itself, because there's a lot of value on top," such as the dashboarding, reporting, and analytics solutions.

The lightweight, just-enough-code approach popularized by AWS Lambda has spawned a slew of projects that extend on it (ZappaJaws), and frank imitation from competing cloud vendors (Google Cloud Functions). But Arimura thinks of in more general terms.

"We're like a layer on top of all compute," Arimura said, a "job API for developers," as opposed to merely being "a widget that manages Docker containers." is currently soliciting applications for Kratos's public beta. Arimura anticipates something will be released to the general public within the next sixty days or so.
