How The Internet Works

If Spotify isn’t available in your country, you can use another podcasting app to access the episode!

There’s a classic interview question: what happens when you type a URL into the browser? To answer this question, we need to explore how the internet works. In this episode, our first of season 4, we’ll dive into URLs, DNS, basic networking, and how the browser works.

AWS Amplify is a suite of tools and services that enables developers to build full-stack serverless and cloud-based web and mobile apps using their framework or technology of choice on the front end.

Using Amplify you can quickly get up and running with things like hosting, authentication, managed GraphQL, serverless functions, APIs, machine learning, chatbots, and storage for files like images, videos, and pdfs.

Amplify is built especially in a way to enable traditionally front-end developers to be successful because they can use their existing skillset to build real-world full-stack apps that in the past would require deep knowledge around back end, dev ops, and scalable infrastructure.

The Amplify Console then allows you to use a Github repository to deploy to a globally available CDN, with CI and CD built-in.
