Which service in SFCC provides caching for static assets?

The Content Delivery Network (CDN) is the service in Salesforce Commerce Cloud (SFCC) that provides caching for static assets. CDNs are designed to deliver content such as images, stylesheets, and JavaScript files to users in a fast and efficient manner by caching these static assets at multiple points of presence (PoPs) around the globe. When a user requests a static asset, the CDN serves the cached version from the nearest PoP, significantly reducing load times and improving the user experience.

This caching mechanism allows for lower latency and improved performance since the content does not need to be fetched from the origin server every time a request is made. By offloading static content delivery to a CDN, the application server is freed up to handle dynamic requests, which can lead to overall better resource utilization and scalability of the application.

The other services mentioned do not specifically focus on caching static assets. The Application Server handles the processing of application logic and dynamic content. The Service Layer provides a way to interact with services within the SFCC architecture but does not directly manage static asset caching. The Data Warehouse is more focused on data analytics and reporting rather than asset delivery or caching.
