What is Cloud-Native?
Cloud-native is an approach to building and operating applications that takes full advantage of cloud computing environments. It's about designing systems specifically for the cloud, embracing concepts like microservices, containers, orchestration, and DevOps practices to achieve greater scalability, resilience, and velocity.
The Cloud Native Computing Foundation (CNCF) defines cloud-native as: "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."
