In Domain-Driven Design (DDD), infrastructural services are those that handle concerns outside the core business logic, typically involving interactions with external systems or resources. These services are essential for supporting the application but do not contain domain-specific logic. Here are some examples of infrastructural services in DDD:
Email Service:
This service is responsible for sending emails, such as notifications or confirmations, to users. It interacts with an external email server or service provider like SendGrid or MailChimp[4][6][12].
Logging Service:
A logging service captures and stores log messages generated by the application. This can include error logs, audit trails, and other significant events. It often interacts with logging frameworks or external systems like Fluentd or Elasticsearch[4][12].
Persistence Service:
This service handles the storage and retrieval of data from databases or other persistent storage systems. It abstracts the database interactions, allowing the domain layer to remain agnostic of the underlying data storage technology[1][4][12].
Messaging Service:
Messaging services manage the sending and receiving of messages between different parts of the system or between different systems. This can include message queues like RabbitMQ or Kafka, which facilitate asynchronous communication[12].
File Storage Service:
This service manages the storage and retrieval of files, such as doc...
