Cloud native is about how you build software to fully exploit the cloud, not just where it runs. The payoff: scalable, resilient, manageable systems.

Going cloud native lets teams ship faster, scale with demand, recover from failures automatically, and use cloud resources efficiently.

At the core sits containerization: a lightweight package bundling your code, runtime, libraries, and settings so the app runs the same anywhere.

Containers give you portability across environments, isolation so apps do not clash, and far less overhead than full virtual machines.

Immutability means a deployed container or server is never modified in place. Need a change? Build a fresh one and replace the old entirely.

So you never patch a live container. To fix a bug, you build a new image with the fix and swap it in. Consistent deploys, simple rollbacks.

With many containers across many servers, you need orchestration to automate deploying, scaling, and managing them. Kubernetes is the classic example.

Orchestration gives you auto-scaling for traffic spikes, self-healing that replaces dead containers, and load balancing across the rest.

These principles compound: containers package the app, immutability keeps deploys predictable, and orchestration runs it all at scale.

Which of the following best describes the principle of immutability in cloud-native development?

Recap: cloud native rests on containers for packaging, immutability for consistency, and orchestration for scale. The base for resilient modern software.
