Webpage content is generally static or dynamic. Static content is the same content served to every visitor, whereas dynamic content changes. Some of the world’s busiest websites are based on dynamic content, such as news sites with lists of headlines, or ecommerce sites with the latest deals.

While you can use serverless technology to build entire web applications, you can also use microservice-based backends to bring dynamic functionality to existing websites.

The Serverless Land website uses this approach to generate dynamic results for visitors. On the site, the What’s New page aggregates feature release information from over a dozen different AWS services. A backend service collects this information from public RSS feeds, then the frontend fetches the data from a public endpoint.

The solution uses two separate microservices. One fetches the data on a schedule from external data sources and stores the result in a database. The other serves the frontend web application, fetching the results from the database.
