Many successful open source companies generate revenue through dual licensing. By offering the same software under both an open source license and a commercial license, developers can encourage community adoption while creating sustainable business opportunities. Learn how dual licensing works,
Applications that fetch secrets directly from AWS Secrets Manager during startup often work perfectly in development but fail under production-scale deployments due to API throttling. Learn why throttling occurs, how it impacts application startup, and how to build scalable, resilient secret manage
Choosing between PlanetScale and Xata isn't just about pricing. While both target modern cloud applications, they solve different problems with different database architectures. Learn how they compare in branching workflows, free tiers, query performance, scalability, developer experience
Write-through caching with Redis is designed to keep cache and database data synchronized, yet many production systems still experience stale reads due to replication lag, race conditions, failed writes, and inconsistent cache updates. Learn why stale data occurs, how to identify the root causes,
RDS Proxy pinning quietly bypasses connection multiplexing and starves your pool without a single error in your logs. Here's how to detect it, diagnose the root cause, and eliminate it for good.
Amazon SQS guarantees at-least-once message delivery, meaning duplicate processing is always possible. One of the most common causes is an incorrectly configured visibility timeout. Learn how visibility timeouts work, why duplicate processing occurs, and how to build resilient, idempotent consumers
Your ECS service should scale out automatically when traffic spikes, but it doesn't — tasks stay at minimum count while CPU pegs at 100%. Here's how to diagnose and fix stalled auto scaling before it costs you uptime.
A failed Terraform apply can leave a lock record in DynamoDB that blocks every subsequent command. Here's how to diagnose the stale lock, safely remove it, and prevent it from happening again.
Deployed your stack and CloudWatch alarms won't move past INSUFFICIENT_DATA? This guide breaks down every real cause — from missing metric namespaces to IAM gaps — and shows you exactly how to fix each one.
Lambda cold starts can turn a 50ms function into a 3-second timeout behind API Gateway — and the root cause isn't always obvious. Here's how to diagnose what's actually happening and fix it systematically.
A failed deployment should automatically return your infrastructure to a healthy state. However, AWS CodeDeploy rollbacks can sometimes stall midway, leaving part of your fleet running the new version while the rest runs the old one. Learn why this happens and how to build rollback-safe deployment
Rate limiting sounds simple until your application starts handling thousands of requests per second across multiple regions. This article compares PlanetScale and Upstash as backing stores for rate limiting systems, examining latency, cost, scalability, operational complexity, and real-world limit
