Example: "Configure Nginx 1.18 as a reverse proxy with upstream load balancing to three Apache servers, implementing SSL termination with Let's Encrypt certificates and HTTP/2 support."
When Talking to Business Stakeholders
Use analogies and business-focused language, emphasizing benefits, costs, and business impact rather than technical details.
Example: "We'll set up a system that automatically distributes website visitors across multiple servers, ensuring your online store stays fast during busy shopping periods like Black Friday."
Documentation Best Practices
