Go was created as a system language, designed to solve real world problems, go is naturally a perfect fit for services. In this presentation I will talk about why Go is great as a system language, why it's easy to develop and operate. During the presentation we will write a Go service that looks up IP addresses as a service. We will focus on operations and devops features of a service, building, deployment, debugging. All the whistles and bells that makes it a dream of a devops engineer.
