Description: The Fetch Policy in the context of services like CloudFront, Rancher, Kubernetes, Amazon Elastic Kubernetes Service (EKS), Kubernetes Engine, and Azure Kubernetes Service (AKS) refers to the rules that define how content is retrieved from the origin server. These policies are essential for optimizing content delivery and ensuring that end users receive information efficiently and quickly. In the case of caching services, for example, these policies determine when and how cached content should be accessed and when it is necessary to request it again from the origin server. This includes aspects such as cache duration, the conditions under which cached content should be invalidated, and strategies in case of failures. In Kubernetes environments, these policies can influence how pods and services are managed, ensuring that applications remain available and recover effectively from any disruptions. In summary, the Fetch Policy is a critical component for managing content and services in the cloud, ensuring that applications and data are always accessible and optimized for performance.
