Overview

The IT professional who knows DevOps plays a crucial role in modern operations management and software development. DevOps is a cultural and practical approach that aims to integrate development (Dev) and operations (Ops) teams, promoting continuous and efficient collaboration throughout the software development lifecycle. 

In the introductory section, we delve into the essence of DevOps and the contemporary approach to developing and releasing applications. The discussion spans the requisite tools for the initial deployment phase. Moving forward, Section 2 navigates through Infrastructure as Code using Vagrant, elucidating the process of crafting virtual machines (VMs) and automating deployments, including the installation of Apache and application repositories. Section 3 explores Terraform's prowess in orchestrating cloud infrastructure, from installation procedures across Windows and Linux environments to specifying cloud providers and configuring security settings for VMs. Section 4 ventures into the realm of containerized applications, exploring Docker's role in microservices architecture and the steps to run, personalize, and deploy containerized applications, alongside insights into Docker Hub. Section 5 transitions to GitLab, elucidating its significance in facilitating deployment pipelines and guiding through the creation and customization of pipelines to update applications seamlessly. Finally, Section 6 escalates the discussion to scaling applications using Kubernetes, detailing the setup process in Google Cloud Platform (GCP), configuring databases, orchestrating load balancers, and conducting load tests, with a glance at managing services in public clouds and future directions.  

By the end of the course, you will have a deep understanding of DevOps.
