2. 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.
