IBM Cloud Managed Istio vs. Kubernetes

It is a perfect application when you have multiple users and/or developers and you want to create rules and standards for access and the ability to change access levels. The reporting of usage is good, but adding more granularity into the metrics that have been used to measure are not specific enough. They provide detail but drilling into the detail would be more appropriate i.e. access to the baseline data.

Along with all the best features and support by k8s, the automatic container scheduling to worker nodes and also self-healing containers which is what I like the most. On the other side, when I was installing the k8s cluster on CentOS 8, it was quite difficult for me, but never mind it is working as we expected and it is a one-time effort. Especially, in my case, there are more than 7 application containers required to run and communicate with each other, so for us, Kubernetes is an optimal solution.

• Debug issues
• Monitoring
• allows many services form many different sources

• 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

• Still missing functionalities for a full usage as traffic director.

• 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.

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

1) One-stop solution for all the complex network connectivity managed by [IBM Cloud Managed Istio]. 2) Nice dashboard to understand the flow. 3) Easy to troubleshoot the service if any one of the APIs is not responding. 4) We can integrate it with Azure Kubernetes service and other cloud provider Kubernetes services. 5) Monitoring the health of the pods can be easily configured and alerts can be triggered very accurately with this tool.

As I said earlier also - - K8s manage the workloads better as compared to OpenStack in terms of reliability, observability & reachability. - K8s is not limited to only a single networking or storage solution as compared to OpenStack. - Networking (which is a key concept) is much simpler in K8s as compared to OpenStack. - It is possible to upgrade your applications without downtime in K8s but in OpenStack, you either have to divert the traffic or face an outage because you have to delete the whole stack & then recreate it.

• Management burden is reduced resulting in positive ROI.
• Application is being seamlessly instrumented with good impact on business.

• 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.
