   Go (fiber) vs. Go (stdlib) vs. Go (gin): Performance Benchmark in Kubernetes

   The post compares the performance of Golang HTTP frameworks—Fiber, Gin, and the Golang standard library—within a Kubernetes environment. By deploying the applications on an AWS cluster and measuring their CPU, memory usage, client-side latency, and requests per second, the test finds that Fiber performs best in terms of resource usage and latency. However, the standard library is recommended for general use due to its reliability and broad suitability for most applications.

   An Ode to Logging

   Effective logging is crucial for software development, helping identify errors and streamline debugging. Use proper loggers instead of print statements in production, distinguish log levels (Info, Error, Warn, Trace), and ensure logs are both human and machine-readable with structured formats like JSON. Group events with Spans to build Traces and always centralize logs with a retention policy to avoid hefty cloud bills.
