Infrastructure as a Code

Infrastructure as a Code or IaC is a method that helps to manage the servers, storage, and network resources. This is a large-scale approach that covers infrastructure configurations. It resolves the crisis of environment drift in the release pipeline. Idempotence is achieved by IaC only which is the ability to produce the same result which is given to a given set of operations. Hence, to manage automated infrastructure knowledge of IaC is a must.

Configuration Management

In the DevOps domain, we require a lot of configuration management which is used when we need the platforms to automate, design, and monitor manual configuration processes. Hence, this section covers all those tools. In order to keep the systems in known desired states, we need configuration management. Through this technology, the consistency of software and systems is highly maintained. When automation is combined with configuration management it improves the efficiency as manual configuration processes are replaced with automated processes.

Ansible Ansible is one of the configuration management tools that helps in the provisioning of network devices, hypervisors, and computing hosts inside the cloud. With the help of ansible, it becomes easy to manage a whole network of computers at once. For working with ansible it's not necessary to have the knowledge of any programming language. The ansible files are human-readable and easy to understand. It has no dependency on any agent software. It is a very excellent and in-demand automation tool.

Chef Chef is the configuration management tool that works on client-server architecture. Here, infrastructure is being managed by writing the code so that the processing becomes automated and code gets deployed easily. It uses Ruby to develop blocks like recipes and cookbooks, which are essential and act as the building blocks in the automation process. The necessary feature of chef is that it focuses on writing code rather than using the manual method. Hence, this section contains all the critical concepts of chef which are necessary to implement in real-time projects.

Puppet Puppet is the configuration management tool developed in Ruby that helps to maintain difficult infrastructure in a very efficient way. This tool comes into the picture when there is a massive infrastructure built and it becomes difficult to maintain them. In such circumstances, Puppet comes into the picture. Let's understand this tool in depth with the help of this section.
