Course description

In this practical lab, you'll configure a fully secure Nginx web server on an Ubuntu EC2 instance using free SSL/TLS certificates from Let's Encrypt. You'll start by setting up a domain record in AWS Route 53, installing and configuring Nginx, and then using Certbot to obtain and install an SSL certificate. You'll also configure automatic certificate renewal to ensure ongoing security. By the end of this lab, you'll have a production-ready HTTPS-enabled web server and a clear understanding of how to automate SSL certificate management.

Additionally, all learners receive dedicated online support through our Slack workspace where you can ask questions, get troubleshooting help, and interact with our team throughout the entire project.

Frequently asked question

Let's Encrypt provides free Domain Validation (DV) certificates that are just as secure as paid certificates for enabling HTTPS. It’s ideal for personal projects, testing, and production sites where OV/EV validation isn’t required.

Yes, you’ll need a registered domain name and access to its DNS settings (via AWS Route 53 or another provider) to create an A record pointing to your EC2 instance.

Yes, Let's Encrypt certificates are valid for 90 days. However, Certbot automates renewal, so you don’t have to manually renew them if set up correctly.
