Caching strategyCaching strategies across the frontend, GraphQL gateway, and backend services.

Messaging & eventsHow Evolve services communicate asynchronously through events and cloud-native messaging.

REST endpoints & webhooksHow Evolve uses REST endpoints for webhooks, payment callbacks, session management, and commercetools API extensions.

Email & notificationsHow Evolve sends transactional emails through a two-layer notification and email rendering system.

Search & AlgoliaHow Evolve integrates search through pluggable providers with Algolia and commercetools support.
