Thanks. BTW, In a microservices architecture, handling multiple asynchronous operations in parallel while dealing with partial failures is a common scenario. To achieve this we can certainly look at following options like

1. Use Asynchronous Operations: We need to ensure that all operations we want to execute in parallel are asynchronous to maximize resource utilization and responsiveness.

2. Circuit Breaker Pattern: We also need to implement a Circuit Breaker pattern for external dependencies. When an external dependency fails, open the circuit, and avoid making further requests for a certain duration. This prevents overloading the failing dependency and allows the system to continue functioning with minimal disruptions.

3. Task Composition: Use the Task.WhenAll method to compose multiple tasks and execute them concurrently. This allows you to parallelize operations effectively.

This is the high level approach I can think of. However, this question is a good candidate for blog. Will try to write a blog for it with example.
