Overall Satisfaction with CoreOS rkt
We use CoreOS rkt in as developers and as an organization. My department uses CoreOS rkt to compartmentalize all of our developer operation tools and to keep systems homogeneous across hardware. My organization as a whole use CoreOS rkt to containerize and scale customer instances.
As a developer CoreOS rkt is a lifesaver, it has allowed us to write tools focused on developer productivity and use them across the department regardless of underlying operating system. We have hundreds of compilers, linters, and unit tests across dozens of languages stored in CoreOS rkt.
As an organization we use CoreOS rkt when spinning up new customers. This has been advantageous because we can run multiple customers from one VPC. It also means we can scale up a customers environment almost instantaneously. We often have customers who's resource needs change on a daily basis, CoreOS rkt has allowed us to scale with our customers.

- Containerization, CoreOS rkt is particularly well suited when running multiple processes on one server.
- Simplicity, CoreOS rkt is easy and quick to get up and running.
- Speed, CoreOS rkt takes few resources and performs with little overhead.
- The API, gRPC is a wonderfully easy framework to use.
- Market share, it's often very difficult to find new talent who use CoreOS rkt.
- Lack of wow features, CoreOS rkt doesn't necessarily offer any immediate advantages over other container solutions.
- Developers spend less time configuring and more time coding.
- Less time training developers as CoreOS rkt lets them use whatever hardware and operating system they want.
- Reduced our IT costs, solutions are containerized using CoreOS rkt meaning they can write one solution with many developers in mind.
- Docker
We evaluated CoreOS rkt and Docker when selecting software solutions for my department. We ended up using CoreOS rkt because of how well it fits with CoreOS and the choice of gRPC for the API. We provide a managed service that runs CoreOS on a bare metal server, CoreOS rkt was a logical choice for compatibility. We also found that developers were having better scusess interacting with gRPC than other container engines REST protocols. It was a close race but eventually there were just enough small benefits to push CoreOS rkt in front of the competition.
