JavaScript Cloud Native Development Cookbook

Utilizing cache-control

Autonomous, cloud-native services maintain their own materialized views and store this replicated data in highly-available and extremely performant cloud-native databases. When combined with the performance of an API Gateway and FaaS, it is typically unnecessary to add a traditional caching mechanism to achieve the desired performance for a user-facing, backend-for-frontend (BFF) service. That being said, this doesn't mean we shouldn't take advantage of the CDN, such as CloudFront, that is already wrapping a service. The following recipe will therefore show you how to utilize cache-control headers and leverage a CDN to improve performance for end users, as well as reduce the load on a service.
