Scalable Microservices with Go

Go (Golang) has become the de-facto language for high-performance backend systems. Its simplicity, combined with powerful concurrency primitives, makes it ideal for building scalable microservices. In the case of UniDirectory, we needed to scrape and process data from hundreds of sources simultaneously. Go's goroutines allowed us to build a crawler that was both lightning-fast and extremely memory-efficient. We used a clean architecture approach, separating our business logic from terminal implementations. This post covers our journey from a monolith to a distributed system, and why Go was the right choice every step of the way.
