Introduction: What is IaC?

Today we will become acquainted with a concept known as Infrastructure as Code. The idea of Infrastructure as Code is becoming more and more popular today. IaC is a method used to manage and provision a data center via defined machine-readable files instead of physical hardware configuration or other interactive configuration tools. This article will share what it is used for, why it is important, and why businesses strive to utilize this platform to achieve a desired set of results. It is essential to understand that we will consider both the theoretical and practical parts of IaC.

The web-based Kubernetes console is an interface that provides information about the state of the Kubernetes cluster. The dashboard is also used for deploying containerized applications as well as for general cluster resource management. Traditionally, kubectl is primarily used in the terminal for nearly all cluster related tasks. Still, it is useful to have a visual representation of our cluster in a user-friendly interface. To install the dashboard, kubectl needs to be installed and running on the server.

What is Serverless?

Serverless computing (or serverless for short), is an execution model where the cloud provider manages and allocates resources dynamically without the need for infrastructure. Resource allocation is based on the as needed, real-time use of your application or website. When running this type of hosting, you are only charged for the amount of resources that our code uses.
