Chaos Monkey Won't Find Your Bug
Infrastructure and application chaos break different layers and find different bugs. Netflix built two systems for a reason. Most enterprises buy just one.
Using proxymock with AWS Services
Record AWS API calls with proxymock, inspect the capture, and run local mocks while keeping IAM, signing, and cloud-state integration tests.
Using proxymock with GCP Services
Record Google Cloud API calls with proxymock and test locally. Understand the limits around IAM, OAuth, quotas, and stateful behavior.
What is Volume Testing? Best Practices
Test growing data volume independently from concurrency. Prepare representative datasets, reset state, and inspect query plans and resource limits.
What does OOMKilled mean and how do I prevent it?
Diagnose Kubernetes OOMKilled events. Separate memory limits from CPU throttling, inspect termination evidence, and size resources from measured workloads.
What is Load Testing? Best Practices for Getting Started
Start load testing with a bounded workload, representative data, measured duration, and explicit latency, error, and correctness goals.
