This video provides a comprehensive guide on how to set up DNS and SSL/TLS configurations for a website using Cloudflare. By following the steps demonstrated, viewers will be able to configure the necessary DNS records, including an A record and a CNAME record, to properly direct traffic to the origin server and leverage Cloudflare's security features. These techniques can be applied to another CDN (content delivery network) if you are not using cloudflare.
Here are the key things you will be able to do after you watch this demo:
Configure DNS records, including an A record and a CNAME record, to direct traffic to the origin server.
Explain the purpose and benefits of enabling the "proxied" setting for DNS records to enhance security.
Differentiate between the various SSL/TLS encryption mode options (full, flexible, strict) and apply the appropriate configuration to establish a secure connection.
Evaluate SSL connections by interpreting browser security indicators and certificate details.
Recognize the option to use a custom SSL certificate branded to the domain and describe the process to deploy it on both the Cloudflare edge server and the origin server.
Collaborate with Cloudflare support to set up advanced SSL certificate configurations for specific use cases.
Demonstrate the overall process of setting up DNS and SSL/TLS for a website, including the necessary steps and considerations to ensure a secure and reliable connection.
Troubleshoot and resolve any issues that may arise during the DNS and SSL/TLS setup process.
Communicate the technical details and benefits of the implemented DNS and SSL/TLS configurations to stakeholders.
Apply the knowledge gained from this demo to set up secure and reliable web infrastructure for future projects.
Cloudflare DNS Setup Instructions (0:02)
Josh Lomelino explains the need to create two records: an A record and a CNAME record to direct traffic to the anomaly amp server.
The A record should have the website name as the host and the provided IP address as the value.
Proxied should be turned on to hide the origin server's IP address, making the connection more secure.
The A record should be saved after entering the IP address.
Adding the CNAME Record (2:09)
Josh Lomelino instructs to add a CNAME record with the host set to www and the value set to the website name (e.g., www.createmedia.com).
The CNAME record ensures that www.websitename.com redirects to the main website and supports SSL.
Proxied status should be set to cloak the origin server's IP address.
The CNAME record configuration ensures that SSL is enabled for www subdomains.
Configuring SSL Settings in Cloudflare (3:21)
Josh Lomelino discusses the SSL/TLS encryption mode options: full, flexible, and strict.
Full mode ensures an SSL certificate between the user and Cloudflare, and between Cloudflare and the origin server.
Flexible mode allows SSL between the user and Cloudflare but not between Cloudflare and the origin server.
Strict mode provides the strongest SSL connection but requires testing to ensure full mode is working first.
Testing and Troubleshooting SSL Connections (6:20)
Josh Lomelino explains the process of testing SSL connections by checking the browser's security icon.
The security icon indicates whether the connection is secure and provides details about the SSL certificate.
Users can check if they are using a shared certificate or a custom certificate branded with their domain.
Most users won't need to drill down to the certificate details, but the techniques shown cover most use cases.
Advanced SSL Certificate Management (6:40)
Josh Lomelino mentions the option to purchase a custom SSL certificate for the Edge server.
High-end experiences may require deploying a custom certificate to the origin server.
Advanced support may be needed to install the custom certificate on the origin server.
Most cases don't require a custom certificate, but the option is available for enhanced security.
Final Steps and Troubleshooting Tips (8:54)
Josh Lomelino summarizes the DNS and SSL setup process, ensuring a working SSL certificate between the user and Cloudflare.
The final step is to test the setup in the browser to ensure the SSL connection is secure.
Users can check the certificate details to verify the SSL configuration.
