# What is autoscaling & serverless?

* Autoscaling automates horizontal scaling to ensure that the number of workers is proportional to the load on the system

#### Technologies that allow us to scale this way:

### Serverless vs Autoscaling

* Autoscaling is usually discussed on the timeline of \~1h chunks of work
* If you took the concept of autoscaling and took it to its limit, you'd get serverless
* Serverless: define resources that are quickly started and use them on the timeline of \~100ms

### Use case for serverless:

* Serverless is primarily used for services that are somewhat fast to start and stateless
* You wouldn't run something like a CI run with serverless framework
* BUT you might run something like a webserver or notification service
