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 Kubernetes Service is ideal for deploying modern applications on a microservices architecture -- where easy scaling and ability to update are important. IBM Cloud Kubernetes Service also handles automated deployments and load balancing very well, particularly if you're already working in the IBM Cloud ecosystem. There are applications less suited to IBM Cloud Kubernetes Service -- such as very small applications, where managing an IBM Cloud Kubernetes Service cluster would be overkill. Also, users not familiar with container organization might find IBM Cloud Kubernetes Service to be a challenge to manage effectively.

  • 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

  • IBM has a strong focus on serverless and Kubernetes. This shows in the platform. Deploying containers to Kubernetes was very easy.
  • Deploying a Kubernetes cluster through the GUI is very easy and quick. On top of that, IBM Cloud offers a single node cluster for Free.
  • Container Registry is a very good product for managing container images. Integration with Kubernetes was seemless.
  • Portability. To transition from Google Cloud Kubernetes to IBM Cloud Kubernetes took almost no effort. We mostly use the CLI and the standard tools such as kubectl were present.

Cons
Open Source
  • 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.

  • I constantly get this error even when everything is well configured prefect.exceptions.AuthorizationError: [{'path': ['auth_info'], 'message': 'AuthenticationError: Forbidden', 'extensions': {'code': 'UNAUTHENTICATED'}}]
  • Then sometimes the error disapear without changine anything, happened twice to me. Should there be an issue with the authentication service? Please let's improve or let users know why this may be happening.
  • Improve the UX in the browse console when removing many images at once
  • UX on the process of installing KeyCloack operator

We have our application running on a CentOS compartment on IBM Cloud Kubernetes Service. We have been utilizing the help since IBM Cloud initially dispatched. We liked the adaptability and versatility that IBM Cloud Kubernetes Service give us. Since we are tiny, the Kubernetes administration is just utilized at present inside my venture bunch.

We actually haven't had any real problems in our clusters recently and the results we have gotten from adopting IBM Cloud Kubernetes Service have been beyond even our greatest expectations. The community has helped optimize the use of the system and make it relatively simpler to use.

The self-guided support was solid, and there are plenty of online videos to guide first time users, but I think one area of improvement is a faster way to transfer a large quantity of files from our local machine to the cloud for storage (Aspera)

Online training is really an important resource for using these tools. IBM's help center is rich in useful information and tips. Also, external guides and tutorials are available (e.g. on youtube), but I followed only IBM ones and I had no difficulties.

Ease of use. Very intuitive. We have been looking for a product that allows us to orchestrate our docker containers in a way where it allows us to effectively scale our applications to production. It also provides us a way of monitoring all our infrastructure in a very clear concise way.

The IBM Cloud Kubernetes Service is quite flexible platform with profitable Cloud functions performance and the data security through IBM Cloud Kubernetes Service is nice. To manage container easily and process huge amount of data at the same time, the IBM Cloud Kubernetes Service is amazing ad the platform deployment is very easy after training.

IBM's CKS does not offers automatic autoscaling nor vertical scaling (automatic). Other services like Google Kubernetes Engine scales up and down very well

Return on Investment
Open Source
  • 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.

  • IKS can provide around 30% savings when it comes to operational costs since Kubernetes is designed to run applications in most machines in the most efficient manner possible.
  • Managed Kubernetes can save a company time by 45% since Managed Kubernetes usually is seamlessly updated, without any interruptions with the workload. IKS fall into this benefit.
  • We heard people had saved in maintenance downtimes when it comes to Kubernetes by a factor of 10 so IKS can contribute to more flexible and distributed services with virtually no downtime.
