What’s your approach to high availability and fault tolerance?

I design for redundancy—using multiple instances behind load balancers, and designing

services to be stateless where possible. In .NET Core, this often means using resilient

patterns like circuit breakers and retries with Polly.

We also implement health checks and monitoring (Azure Monitor, Application Insights) to

detect issues early. For critical data, backups and failover strategies are baked in. The goal

is minimizing downtime and graceful degradation rather than “perfect uptime” which is often

unrealistic.
