The document presents an overview of cloud native technologies, emphasizing their role in enabling organizations to create scalable applications in varied environments. It highlights key concepts such as containers, service meshes, and microservices, stressing the importance of automation and observability. The Cloud Native Computing Foundation aims to promote these technologies through an ecosystem of open-source projects, making advanced patterns accessible to all.

5. CNCF Cloud Native Definition v1.0
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.
The Cloud Native Computing Foundation seeks to drive adoption of this paradigm by fostering and sustaining an ecosystem of open source, vendor-neutral
projects. We democratize state-of-the-art patterns to make these innovations accessible for everyone.
