How To Build a Hashicorp Vault Server Using Packer and Terraform on the cloud provider [Quickstart]
Vault, by Hashicorp, is an open-source tool for securely storing secrets and sensitive data in dynamic cloud environments. Packer and Terraform, also developed by Hashicorp, can be used together to create and deploy images of Vault. In this tutorial, you’ll use Packer to create an immutable snapshot of the system with Vault installed, and orchestrate its deployment using Terraform.
How To Manage Multiple Servers with Ansible Ad Hoc Commands
With Ansible, you can use ad hoc commands to execute one instruction at a time on one or more remote servers. They are ideal to perform tasks that aren’t executed frequently, and to consult information about the remote systems that Ansible manages. In this cheatsheet guide, you’ll learn how to use ad hoc commands to manage one or more servers with Ansible, and how to perform some common tasks this way.
Infrastructure as Code Explained
In this article, we define Infrastructure as Code (IaC) and explain the benefits of IaC in development and deployment workflows. We also start to learn about Terraform’s role in the IaC workflow and understand “what is ‘state’?” in IaC.
An Introduction to SNMP (Simple Network Management Protocol)
SNMP, or simple network management protocol, is a standard internet protocol used to monitor remote servers, gather information, and even modify states and values on other hosts. Mostly leveraging a client-server model, the protocol is very mature and fairly ubiquitous across networked devices. In this guide, we will introduce you to some fundamental SNMP concepts and take a look at the protocol in broad strokes.
