This Azure tutorial demonstrates creating a virtual network, subnet, firewall, and Bastion to deploy an EngineX web app. The video covers practical steps, including configuring network security groups (NSGs) and Network Address Translation (NAT) rules to control access to the private VM. The Bastion allows secure SSH access, while the firewall protects the application. This segment outlines a practical session demonstrating the creation of a virtual machine, subnets, routes, and firewall deployment, emphasizing the benefits of a hands-on approach over solely theoretical explanations of Azure networking concepts. The presenter explains the practical application of firewalls, NSGs, and routes, making the learning more impactful. This segment provides a high-level overview of the practical session, including the creation of a virtual network, firewall, subnet, and virtual machine deployment. The presenter visually explains the architecture and the purpose of each component, setting clear expectations for the viewers. The presenter also highlights the use of Bastion for secure access. This segment details the creation of a resource group in Azure, emphasizing its importance and mandatory nature. The presenter connects this practical step to previously covered theoretical concepts, reinforcing learning and demonstrating the practical application of resource groups. The presenter also reminds viewers to delete the resource group after the demonstration. This segment focuses on creating a virtual network, configuring security settings, and enabling Azure Bastion and firewall. The presenter explains the rationale behind each configuration choice, including the use of Bastion for secure access to private virtual machines and the importance of firewall policies for controlling access. The presenter also explains CIDR ranges and their impact on IP address allocation. This segment covers the creation of a virtual machine, focusing on configuration choices like image selection, size, SSH key authentication, and network settings. The presenter explains the significance of choosing free-tier services, the use of SSH keys for secure access, and the difference between custom data and user data for deploying applications and scripts. The presenter also explains the importance of deploying the application in a private subnet behind a firewall. This segment details the process of installing EngineX on a virtual machine, including updating repositories, installing EngineX using apt, creating a simple HTML file, and restarting the EngineX service. The steps are clearly explained, making it easy to follow along and replicate the process.This segment focuses on configuring Azure firewall policies to access a private EngineX instance. It explains the concept of network address translation (NAT) rules and their priority in handling multiple rules, providing a foundational understanding of firewall management in Azure.This segment provides a detailed walkthrough of creating and configuring DNAT rules within an Azure firewall policy. It covers setting source and destination IP addresses, ports, and translated IP addresses, explaining the importance of each parameter and how they work together to enable external access to the internal EngineX application.
