Building Scalable Backend Services with Go

Why Go?

Go is a great choice for backend services thanks to its simple syntax and strong concurrency model. Goroutines let us handle high concurrency at low cost.

Packaging with Docker

Compiling each service into a single static binary and putting it in a tiny image makes deployment trivial:

FROM golang:1.22 AS build
WORKDIR /app
COPY . .
RUN CGO_ENABLED=0 go build -o server .

FROM scratch
COPY --from=build /app/server /server
ENTRYPOINT ["/server"]

Conclusion

Go + Docker provides a solid foundation for microservice architectures with small images and fast deploys.
