Serverless architectures embody a massive shift happening in cloud computing.

Simply put, serverless computing changes the way developers think about writing, scaling and maintaining cloud applications.

#What is Serverless?

#About the Name

Coined Serverless by iron.io(?), Serverless doesn't mean there are no more servers, just ones that you no longer have to think about.

Servers with less management Servers with less development costs Servers with less scaling costs Servers with less operational costs Servers with less headache Serverless

Also known as 'Function as a Service' or FAAS

#What isn’t Serverless?

#Benefits of Serverless Architectures

Reduced operational cost
- reduced infrastructure cost and lower operational cost
BaaS - reduced development cost
FaaS - scaling costs
Easier Operational Management
‘Greener’ computing?

#Serverless Challenges

Vender lock in
Security concerns
- larger surface area for attack
No state
Server optimizations out of your hands
Limited configuration options
Infinite Loops of death
Limited execution durations
Cold start times
Testing overhead
Function management (versioning, rollbacks, deployment)
Monitoring overhead
Limited education / patterns in the new space
