Do you know how system architecture changes over time to meet increasing traffic? What does it take to design a hypothetical e-commerce site that scales to millions of users? In real life, you will never create an architecture of that scale from the start. It will be a gradual process. You may start by design a bare minimal site that handles hundreds, perhaps thousands of users.
It will probably look like the following.
How we build a high volume e-commerce website has changed over time. From the LAMP stack to the MEAN stack and many iterations in between. What would it look like to design a site today to take full advantage of what the most popular cloud providers have to offer?
A serverless architecture is what we came up with. You don’t have to manaually manage any services with this architecture. And it scales horizontally with traffic.
