CoreOS rkt / Container Linux (project ended) vs. IBM Cloud Functions

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.

IBM Cloud Functions [is] not the worse product on the IBM cloud. I decided to write this review as I thought it would be balanced. I would still use functions to set up a serverless architecture where execution time is pretty quick and the code is relatively simple. I wouldn't use IBM Cloud Functions for async calls obviously, as costs could be higher. The functions documentation is lacking in terms of CI/CD, and there are unexplainable errors occurring - like the network connection that I mentioned. So I wouldn't just rely on IBM Cloud Functions too much for the entire system, but make sure it's diversified.

• 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

• 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.

• Billing can be a hassle, not the most responsive customer service/support team
• Handles & executes most functionalities, but other platforms offer more scalability if you're seeking consistent and stable growth

• ICF is a lightweight service and does not require runtime configurations
• Scalable on demand and hence there is no need to pay for runtime costs

• 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.

• It directly affected our expenses since we do not need to deploy and maintain a set of separate applications.
• It allowed us to pay for only the amount of time cloud functions run.
• It saved on maintenance and monitoring of the applications it replaced.
