The document discusses the evolution of frontend architectures from monolithic to microservices-based approaches. In the past, frontends and backends were combined in a single monolith application. Now, microservices have separated the backend into independent services while frontends have evolved into independent micro frontends. In the future, micro frontends will be developed independently but composed together with a base application and routed to by an API gateway along with separate microservices for individual products, baskets, and advertising.
