Explanations:
Client Request: The client (browser or app) initiates a request to access a web resource (e.g., a webpage).
DNS Resolution: The client's request first goes to a DNS server to resolve the domain name into an IP address.
Establish Connection: Using the resolved IP address, the client establishes a TCP connection with the server, often using protocols like HTTP or HTTPS.
Load Balancer: The request might be routed through a load balancer, which distributes incoming requests across multiple servers to ensure efficient processing and high availability.
Web Server: The load balancer forwards the request to a web server that handles static content (e.g., HTML, CSS, JavaScript files).
Application Server: The web server passes the request to an application server that processes dynamic content, running application logic (e.g., Python, Java, Node.js).
Database Server: The application server may query a database server to retrieve or store data necessary for processing the request.
Server Response: After processing, the server sends back a response to the client, which may include the requested resource or data.
Client Receives Response: The client receives the response and renders or processes the content for the user.
For example
This structure helps visualize the typical flow of a client request through various layers and servers in a web architecture.
