What architectural model was used in the development of this service?

The architectural model of a service often depends on its purpose and requirements. For example:

• Monolithic architecture — all components are assembled into a single application, which simplifies development but makes scaling more difficult.
• Microservices architecture — the service is broken into independent components that interact via APIs, increasing flexibility and scalability.
• Service-Oriented Architecture (SOA) — similar to microservices but with larger and more integrated services.

In the case of a modern Python service, a microservice approach with REST API or gRPC for interaction between components is often used. For example, a service may consist of several microservices, each responsible for a specific business logic and deployed independently.
