How does GitOps (Argo CD / Flux) change at 10× traffic?

Answers use simple, clear English.

Quick interview answer

At 10× traffic, GitOps (Argo CD / Flux) usually hits queueing and CPU/I/O saturation first — mitigate with concurrency limits, batching, caching, and offloading. Baseline: Desired cluster state lives in Git; controller reconciles continuously. CI builds images; CD is pull-based sync from Git.

Detailed answer

At 10× traffic for GitOps (Argo CD / Flux): 1) Bottleneck shifts from “works on my laptop” to queue delay and resource saturation. 2) Protect the loop/path: timeouts, bulkheads, backpressure, worker offload for CPU work. 3) Scale out carefully: sticky vs stateless, connection pools, cache hit ratio. 4) Prove with load tests that p99 stays inside SLO. Example to cite: Update image tag in GitOps repo → Argo CD syncs Deployment. Parent context: Baseline: Desired cluster state lives in Git; controller reconciles continuously. CI builds images; CD is pull-based sync from Git.
