Serverless, what is it?

...cloud-computing execution model in which the cloud provider acts as the server, dynamically managing 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.”

Who We Are

“The phrase “serverless” doesn’t mean servers are no longer involved. It simply means that developers

no longer have to think that much about them.”~ Ken Fromm

● Image processing

● Ops / Infrastructure

● IoT

● Data normalization - GraphQL Server

● Offloading expensive tasks from your web server

● Discrete API functionality

● Scale is a concern

● Cost is a concern

● Maintenance is a concern

● Tight timeline &

inexperienced team

● Pricing: Some high traffic

situations. Mileage varies

When should I use it? When should I avoid it?
