It's not about the absence of servers. It's about the absence of managing them.
Serverless computing is a cloud execution model where the cloud provider (like AWS, Azure, or Google) dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity.
"Focus on your code, not your infrastructure."
You build the well, maintain the pump, and pay for it even when you aren't thirsty.
You just turn the tap. Water flows instantly. You pay only for the liters you drink.
Use the slider to simulate a massive traffic spike and see how different architectures respond.
No idle costs.
You are charged based on the number of requests and execution duration (in milliseconds). If no one uses your app, you pay $0.
Zero to Infinity.
The provider automatically adds more compute power as traffic spikes and removes it when traffic subsides. No manual config needed.
No OS patches.
No OS updates, security patches, or server provisioning. The cloud provider handles the entire stack below your code.
Trigger based.
Functions run in response to events: an HTTP request, a file upload, a database change, or a timer.
