This is a personal message of gratitude to all operations experts who toil day and night to ensure that applications, servers, hardware, networks and databases are up and working every single hour. In your silence hidden behind the canvas, know that you are impacting lives by making it all amazing for us. Keep doing what you do even though we have no idea where you are and how you do it to keep it all running smoothly. As users continue tapping on tabs, visiting websites, using applications to make their payments or chat with friends, you work behind the façade to ensure everything remains private, fast and stable. Salute to you all and it is my prayer that more people will get to appreciate the work you do with diligence, sacrifice and prowess.
In this celebratory article, we are going to ransack the toolbox of these experts and share two or three resources that aspiring professionals can use to make their future work easier, cleaner and less prone to errors. Two tools that we will be looking for specifically in this episode include Puppet and Chef. We shall begin by getting to know what they are, what they are used for, their importance and why you should consider getting to learn and leverage them in your day to day activities.
Chef: From Chef Website, Chef configuration management software eliminates manual efforts and ensures infrastructure remains consistent and compliant over its lifetime — even in the most complex, heterogenous, and large-scale environments. Users define configurations once and then can apply them across mixed fleets of Linux, Mac and Windows systems, regardless of OS version and architecture.
Puppet: Borrowed from Puppet Documentation Puppet is a tool that helps you manage and automate the configuration of servers. You write Puppet code and then let it do the rest. Puppet code, is declarative, which means that you describe the desired state of your systems, not the steps needed to get there. Puppet then automates the process of getting these systems into that state and keeping them there.
Chef and Puppet are at their core, tools designed to make the work of system administrators as easy as possible. Once every systems professional has had a fair share of the manual process of installing, updating and configuring systems, automation tools come in to take away the repeatable pain that computers can handle without complaining. This is exactly what Chef and Puppet were built to do. They were built to help System Admins configure, update, install and manipulate a cluster of servers from one source of truth. No more need to install applications one by one in each server. You let Puppet or Chef handle it all for you. That, I find amazing.
Well, we should be ready to dip our feet into the waters now and swim all the way to the end of the pool. The following are some of the books you can read and get good grasp of Chef or Puppet.

2. Infrastructure as Code: A Comprehensive Guide to Managing Infrastructure as Code
If you are planning to introduce automation in your environment and you have no idea where to begin or what to do, Austin Young is here with great pride to set your stone rolling in the right direction. Author Austin Young attempts to explore all you need to know regarding Infrastructure-as-Code (IaC). He gives his best to assist you in making informed decisions, if you have plans to implement IaC.
As part of the DevOps practices, IaC offers the ability to manage, configure, and create complex infrastructures by means of executable code. When adopting IaC, the infrastructure is managed by defining the preferred state of the infrastructure in source files, and using a tool to help facilitate that. The source files consist of templates, policy definitions, configuration, code, and other related assets.
A better infrastructure delivery can help improve the important aspects of software delivery performance that drive business outcomes. These include time to restore service, change failure rate, lead time for changes, and deployment frequency.
What You will Learn:
- Understand how IaC works.
- Explore tools and services for updating running servers, building server templates, and provisioning servers.
- Learn about immutable infrastructure and the tools needed to implement it.
- Comprehend how to make an object reproducible.
