Go or Golang is a open source programming language developed by Google, designed for building reliable, scalable application. Its a complied language similar to C developed to improve the programming productivity.

Why Go

Go was designed with the following goals in mind:

  • Cross-platform compatibility: The code run natively in multiple operating systems ie.Linux, Mac, Windows
  • Simplicity: Go has a clean, concise syntax that makes code easy to read and write
  • Efficiency: Go compiles to machine code and offers performance close to C/C++
  • Standard libraries: Rich standard library reduces the need for third-party dependencies for common tasks
  • Small Binaries size : Go binary files are small in size (5–20 MB for most services) and runtime memory is low (a few MB idle).

Where Go Is Mostly Used

  • Cloud & Infrastructure Software
  • Microservices & Backend APIs
  • CLI Tools & Devops Utilities

Applications Built with Go

  1. Infrastructure software (Docker, K8s, Terraform)
  2. Network services (Caddy, Traefik, NATS)
  3. CLI tools (kubectl, gh, Hugo)
  4. Distributed databases (CockroachDB, InfluxDB)
  5. Observability (Prometheus, Jaeger)
