Long term AWS architecture solutions where I participated while working in NFQ for home24 client.
Debugging Node.js Memory leak on Production via Shadowed traffic
Memory leaks are hard to debug, especially when using programming languages with garbage collection. At home24 we had quite a journey searching for the cause of 139 exit codes from crashed docker containers.
