CLOUD NATIVE

What is Kubernetes?

Kubernetes is a portable, extensible open-source platform for managing containerized workloads

and services, that facilitates both declarative configuration and automation.

What is Cloud Native?

Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and

declarative APIs exemplify this approach.

These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make

high-impact changes frequently and predictably with minimal toil.
