As a developer you might have to deal with SSH keys to access specific API/machines, and a common approach is to have one key for everything. For security reasons it’s good to use different ones so that if one of them is compromised the other services are safe and you don’t need to revoke and regenerate the keys for all your API/machines.

In this guide I will show you how to use a different SSH keys for each domain.

DataDog is a monitoring service for cloud-scale applications, in the following guide we’ll see how to create a docker container with the DataDog agent and how to use it to publish custom metrics.

In this guide I will show you how to use gRPC to write a simple client (in C++) and server (in Go) for your service.

For this tutorial we will use the code available in the following Github project: pasdam/grpcExample.

For the client, in this article I’ll show how to write a command line one, but in the repository there is also a GUI client written with the Qt framework.
