How Orchestration Works: The Declarative Model

How Orchestration Works: The Declarative Model

Orchestration platforms like Kubernetes operate on a declarative model. Instead of writing scripts that specify how to perform tasks (imperative), you declare the desired state of your application in configuration files (manifests).

For example, you declare: "I want 3 replicas of my 'web-app' container, each with 1GB of memory, exposed on port 80."

‍The orchestration engine's job is to continuously work to make the actual state of the cluster match this declared desired state. If a container fails, it starts a new one. If traffic increases, it creates more replicas. This is a powerful, self-correcting system.
