Kubernetes vs. Podman.io

K8s should be avoided - If your application works well without being converted into microservices-based architecture & fits correctly in a VM, needs less scaling, have a fixed traffic pattern then it is better to keep away from Kubernetes. Otherwise, the operational challenges & technical expertise will add a lot to the OPEX. Also, if you're the one who thinks that containers consume fewer resources as compared to VMs then this is not true. As soon as you convert your application to a microservice-based architecture, a lot of components will add up, shooting your resource consumption even higher than VMs so, please beware. Kubernetes is a good choice - When the application needs quick scaling, is already in microservice-based architecture, has no fixed traffic pattern, most of the employees already have desired skills.

While it always depends on your use case, I believe security concerns of need for root user is a concern, so it is worth considering daemonless container service over Docker, which works just as good and has support for docker compose. Another good reason is the licensing for enterprise usage, which podman has no restrictions for. It’s also a great choice for OpenShift integration, which is seamless and works well with Rancher as well.

• Complex cluster management can be done with simple commands with strong authentication and authorization schemes
• Exhaustive documentation and open community smoothens the learning process
• As a user a few concepts like pod, deployment and service are sufficient to go a long way

• It’s daemonless, so somewhat more secure.
• It works exceptionally well and is compatible with Docker compose
• Podman Desktop actually makes individual usage also pretty easy.
• It can be used as Docker alternative with almost no additional steps

• Local development, Kubernetes does tend to be a bit complicated and unnecessary in environments where all development is done locally.
• The need for add-ons, Helm is almost required when running Kubernetes. This brings a whole new tool to manage and learn before a developer can really start to use Kubernetes effectively.
• Finicy configmap schemes. Kubernetes configmaps often have environment breaking hangups. The fail safes surrounding configmaps are sadly lacking.

• Podman desktop is getting more stable with each version, but does need more UX friendliness as well.
• Official support for development tools and IDEs is missing for most tools
• It works well with Kubernetes, but I wouldn’t mind additional improvements

The Kubernetes is going to be highly likely renewed as the technologies that will be placed on top of it are long term as of planning. There shouldn't be any last minute changes in the adoption and I do not anticipate sudden change of the core underlying technology. It is just that the slow process of technology adoption that makes it hard to switch to something else.

It is an eminently usable platform. However, its popularity is overshadowed by its complexity. To properly leverage the capabilities and possibilities of Kubernetes as a platform, you need to have excellent understanding of your use case, even better understanding of whether you even need Kubernetes, and if yes - be ready to invest in good engineering support for the platform itself

Most of the required features for any orchestration tool or framework, which is provided by Kubernetes. After understanding all modules and features of the K8S, it is the best fit for us as compared with others out there.

Podman is Daemonless, lightweight and doesn’t charge us for commercial usage, so it’s a relief for startups. Minikube and Rancher are a bit more complex for our use cases; so we keep things simple, fast and secure with Podman that can easily be managed with Podman Desktop and other works with our docker-compose based projects without issues.

• Because of microservices, Kubernetes makes it easy to find the cost of each application easily.
• Like every new technology, initially, it took more resources to educate ourselves but over a period of time, I believe it's going to be worth it.

Incentivized

• We definitely feel more secure.
• We do not suffer from memory or cpu overuses as it uses fedora coreOS which is lightweight
• We do not have to worry about license payments for our basic usages.
• It’s open source so quick fixes imminent with maximum transparency.
