This guide provides step-by-step instructions on how to connect to a virtual machine using the Remote - SSH extension in Visual Studio Code. For demonstration purposes, an AWS Instance is used as an example in this article.

Terraform is an infrastructure as code tool that lets you build, change, and version infrastructure safely and efficiently. This includes low-level components like compute instances, storage, and networking; and high-level components like DNS entries and SaaS features.

Master/slave is a model for a communication in which one device or process (known as the master) controls one or more devices or processes (known as slaves). Control always flows from the master to the slave(s) once the master/slave relationship is established. Jenkins Master: Schedule the jobs, assign slaves, and send build commands to slaves to execute the jobs. It will also monitor the slave state (offline or online) and get back the build result responses and the display build results on the console output. Jenkins Slave is a java executable which receives the build instructions from the central master node. There is no need to install Jenkins on the slave node. It is sufficient to have a JRE (Java Runtime Environment) installed on the slave node.

Jenkins is an open-source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration, and continuous delivery. Jenkins is an open-source continuous integration/continuous delivery and deployment (CI/CD) automation software DevOps tool written in the Java programming language. It is used to implement CI/CD workflows, called pipelines. We can install Jenkins through native system packages, Docker, or even run standalone by any machine with a Java Runtime Environment (JRE) installed.
