What is Kubernetes?
Kubernetes is a portable, extensible open-source platform for managing containerized workloads
and services, that facilitates both declarative configuration and automation.
![Page 16: for Non-Coders Kubernetes - DevOn Summit · A lot of money $$$ The average company uses 5-6 cloud platforms and 300-3,000 cloud services - Sky Cloud spending will top $203.4 billion](https://reader034.vdocument.in/reader034/viewer/2022042223/5ec97fac84b30f6adb0c00ce/html5/thumbnails/16.jpg)
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.
