Enterprises around the world are waking up to the containers and Kubernetes trend. There are numerous benefits of delivering an application as container packages to Kubernetes but at the same time, the process of app containerization and the subsequent app deployment to Kubernetes can hit many roadblocks. Since the idea of using Kubernetes and containers for app delivery is fairly recent, the transition from traditional delivery systems to these modern delivery systems is a bumpy ride.

Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.

In many blockchain platforms such as Ethereum and Bitcoin, data confidentiality is a kind of excluded item in their blockchain framework. In these distributed blockchain platform transactions are executed in every participant node in the network. So, every transaction in the network can be visible to all the peers. The ledger update process through all the endorsed peers and has to reach an agreement among all before it committed successfully to the ledger. So, in this scenario creating a private record and comprises within a certain group of participants in the network is a complete “No”.

The advent of Cloud and Container technology ushered a new era in distributed computing at “planet scale” which was unheard of and unimaginable just a decade ago. Another interesting movement was brewing up a decade ago which bolstered delivering these complex solutions at high speed and accuracy, DevOps.
