Kubernetes, Docker & lambda

How is Kubernetes differ from docker and lambda?

Kubernetes: It is generally referred to as k8s is an open-source system for scaling, management of containerized applications.

Docker: It is a set of platforms that use os level virtualization to deliver packages called containers.

Lambda: It is a serverless computing platform provided by Amazon as a part of amazon's web services.

Kubernetes vs Docker:

Kubernetes is very complex to install whereas docker is easy to install.

The cluster configuration is very strong in Kubernetes whereas the docker cluster configuration is weak.

In Kubernetes, GUI comes with an inbuilt dashboard whereas GUI is not present in the docker platform.

Kubernetes can do auto-scaling but docker cannot perform auto-scaling.

Kubernetes supports more than 5000 nodes but docker only supports 2000+ nodes.

Kubernetes is organized for one single large cluster but docker is organized for a set of multiple smaller clusters.

Kubernetes vs lambda(serverless):

Serverless can become expensive whereas Kubernetes is cost-effective.

Serverless can integrate with many services whereas Kubernetes can’t.

There is no need to set up clusters in serverless whereas cluster configuration is strong in Kubernetes.

Kubernetes is portable whereas serverless is very difficult to migrate.

No particular infrastructure is maintained in serverless but Kubernetes has immutable infrastructure.

· Both the approaches are steps forward in terms of maintainability, performance, and cost-saving platforms.

· The biggest advantage of Kubernetes among the three is that it can handle your cluster like it was a regular server farm, you can recreate parallelism between servers and your cluster components.

· We cannot consider serverless as a replacement for containers.

· On comparing quality, AWS lambda is preferable.

· AWS lambda meets the need for business than Kubernetes.

· Docker is currently the most popular container platform. It appeared on the market at right time. It was open-source from the beginning.

· Kubernetes, Mesos, docker swarm are some of the more popular options for providing an abstraction to make a cluster of machines behave like one big machine which is vital in a large scale environment.

· Containers are not easy to manage at volume in a real-world production environment. Containers at volume need an orchestration system. So, Kubernetes is a suitable system for this task

· This is the reason why Kubernetes became more popular.

· Kubernetes is regarded as a market leader.

· Control plane in the Kubernetes facilitates for orchestration in the Kubernetes platform.
