About the Talk

This session highlights Sneha Inguva’s networking journey through Go. She discusses the useful packages, key learnings, and struggles faced while building a variety of networking services within and outside of DigitalOcean. Walk away with a clear understanding of how to specifically leverage Go for your own networking needs.

What You’ll Learn

  • How to leverage Go’s net package and several open-source packages to build common networking primitives such as load balancers, port scanners, and DHCP servers
  • Go’s packages for leveraging various connections (Unix sockets, raw sockets, and packet sockets) to send packets or frames
  • Networking protocols used by the aforementioned services
  • Concurrency benefits of Go and struggles of testing networking services

Sneha’s Networking Journey Through Go

“My foray into Go began a few years ago when I started working at DigitalOcean. While building an abstraction layer on top of Kubernetes and familiarizing myself with the language, I began to love it. Syntactically simple, with amazing concurrency primitives and a wonderful community, Go was an excellent choice for a cloud-hosting company with a variety of low-level, server-side microservices.

Two year ago, however, I joined the software-defined networking team and learned of another application of Go; networking services. The networking team at DigitalOcean uses Go for a variety of purposes — from DHCP servers to IP address management services, to even wrappers around virtual switch tooling. Intrigued, I decided to also investigate how Go could be used to build other services such as port scanners and load-balancers.

This session highlights my networking journey via Go. I discuss useful packages, key learnings, and even struggles faced while building a variety of networking services within and outside of DigitalOcean. I discuss both relevant packages within the standard library and open-source packages used to implement key network protocols. Through this talk, I hope you gain an understanding of how to specifically leverage Go for your own networking needs.”
