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
