What Happens When You Type a Website URL?
Ever wondered what happens behind the scenes when you open a website? Here’s a simple look at DNS, servers, networking, and AWS.
Every day, we type a website address into a browser and the page appears within seconds. But what actually happens behind the scenes?
It starts with DNS.
When we enter a domain name, DNS helps translate that human-readable name into an IP address so the browser can find the right server.
Next, the browser sends a request to the server. That request travels through the internet until it reaches the infrastructure hosting the application.
This is where cloud computing becomes interesting.
A website can be hosted using services such as Amazon EC2, while Amazon S3 can store images, files, and other static content.
For websites that receive many users, services such as Elastic Load Balancing can distribute incoming traffic across multiple servers.
Security is also important. AWS IAM, security groups, and other security controls help manage who can access resources and what they are allowed to do.
Finally, the server processes the request and sends the response back to the browser, where we see the webpage.
What looks like a simple click actually involves DNS, networking, servers, security, storage, and cloud infrastructure working together.
Learning these fundamentals helped me understand that cloud computing is not just about individual AWS services. It is about understanding how different components work together to build reliable applications.
