CoreOS rkt

CoreOS rkt is well suited for any development environment where operating systems and hardware are not homogeneous. CoreOS rkt allows us to write code on one machine with the confidence that it will work on any other. This has been immensely helpful as our developers are often switching to the latest and greatest machines and operating systems. CoreOS rkt is less suited for environments that are not Software as a Service. There is often no need to bring the entire developer environment and associated dependencies when delivering a one time product. In these environments CoreOS rkt just adds unneeded overhead.

Swarm

Great for light frontends and (REST) microservices that don't depend on hardware/drivers and just do DB/file IO. Not so great for dev virtual machines and testing complex network configurations.

Pros

CoreOS rkt

  • Running a secure container without messing up with low-level details
  • Very clear and straightforward approach to building a container
  • A way to go for new projects thinking of containers
  • Comprehensive and well-written documentation compatible with UNIX keep it simple way of thinking

Swarm

  • Up and Down scaling of decentralized microservice instances
  • Remote maintenance and deployment of the existing docker based services
  • Smallest possible down time of our services upon the necessity of deployment, and maintenance routines

Cons

CoreOS rkt

  • 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.

Swarm

  • Small community - not a lot of information available outside of the documentation.
  • Logging - centralized logging for all applications is something we wish was available.

Swarm

When compared to Kubernetes, Docker Swarm becomes easier to adopt, since it's more intuitive, or 'native' to the Docker Containers technology, as it's the native option. Also, it's a lot easier to set up. Although Docker Swarm has a somewhat steep learning curve, when compared to Kubernetes, it becomes a lot simpler to adopt, and use. Docker swarm is free of use, and requires no specific specialized paid service.

Return on Investment

CoreOS rkt

  • 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.

Swarm

  • With Swarm we managed to have the horizontal network bandwidth scale to gather data from clients on slow internet connections
  • A minor negative is that you always need at least 3 nodes for redundancy, which makes it less ideal for quick proof of concept type scenarios.
