CoreOS rkt / Container Linux (project ended) vs D2iQ Mesosphere

Likelihood to Recommend

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.

Mesosphere is well suited for orchestrating workloads. It supports Docker as a container as well as support others. It is highly suitable for running resilient and auto recovering big data/application containers. Mesosphere has proven time and again to be production ready at a massive scale. It supports native single button/API call scale up and scale down and supports various deployment patterns like Blue-Green and others.

Cons

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.

Setting up is a bit of a hassle, especially ZooKeeper state management and mesos and marathon quorum.
Occasionally, I observed some failures when deploying something onto Marathon. Logging or detailed error reporting can help.
Stale containers and inconsistent states resultant of the cluster failure are hard to solve and need a complete system restart to get it back to normal state.

I happen to like mesosphere because it integrates well with a Jenkins based workflow, Deis is a little more Heroku like and it's not clear how to fit that model into a continuous-integration process. Kubernetes has also been criticized for being complicated.

Return on Investment

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.

I see mesosphere as having a positive impact overall on the industry trending Docker and containers in general.
Seeing how mesosphere helps and simplifies things for the developer and ops, it is definitely a game changer.
Native support of on demand scaling up and down as per the need is one of the best features.
