Are there many integrations in the system? How many and what are the examples?

Systems with a large number of integrations typically have from several to dozens of external and internal connections. For example:

• Integration with CRM systems for synchronizing clients and deals.
• Connection to payment gateways for processing transactions.
• Interaction with analytics and monitoring systems.
• Integration with external APIs to obtain data (e.g., geolocation, weather).

The number of integrations depends on the scale and specifics of the project. In my experience, there have been from 5 to 15 integrations, including REST API, SOAP services, and message queues (Kafka, RabbitMQ). Each integration requires a separate approach to error handling, security, and monitoring.
