## Description
The Gateway Aggregation pattern uses a gateway to aggregate multiple individual requests into a single request. Instead of the client making multiple calls to different services, it makes a single call to the gateway. The gateway then makes the necessary calls to the backend services, aggregates the results, and returns a consolidated response.


## Use Cases
Use when a client needs data from multiple services or when you want to reduce the number of client-service interactions.





## Trade-offs


### Advantages

- Reduced client complexity

- Fewer network round trips

- Centralized data aggregation

- Improved performance for multi-service calls




### Considerations & Drawbacks

- Gateway complexity

- Potential performance bottleneck

- Coupling to gateway
