*Serverlessisjustaname,PaulJohnston
“[…] is a cloud computing code execution model in which the cloud provider fully manages starting and stopping virtual machines as necessary to serve requests, and requests are billed by an abstract measure of the resources required to satisfy the request, rather than per virtual machine, per hour.”
-- Wikipediahttps://en.wikipedia.org/wiki/Serverless_computing
“Quick and easyrun pieces of code* in the cloud, without worrying about infrastructure or maintenance.”

#2Building the real stuff*!… in 3 stages
*finally!
Yeaaah,butwhatcanIbuildwith’em?
Scenario 0The Easy Cake
use HTTP trigger to provide HTTP endpoints
to
build an “Is the cake a lie?” service
Scenario 0 – Easy cake! – Simple HTTP endpoint

Scenario 2Like a pro!
use Blob Trigger to let function react on storage I/O of other function
to
build an image resizing service

*’nuff said!
Cool stuff so far … and the costs?
It’s free**for the 1 million executions and the first 400.000 GB/s
Function executes 2.000.000 times with a duration of 1 second using 1536MB RAM
Resource consumption costs
2 million exec * 1 second = 2 million seconds1536 MB / 1024 MB = 1.5 GB1.5 GB * 2 million seconds = 3 million GBs3 million GBs – 400000 GBs = 2.6 million GBs2.6 million GBs * 0.000016 $/GBs = 41.60 $
Execution costs
2 million exec - 1 million exec = 1 million exec 1 million exec * 0.20$ = 0.20$
41.60$ + 0.20$ = 41.80$
Pricing OverviewPricing Calculator
Same example – just with 128MB RAM
0 $ + 0.20$ = 0.20$
Resource consumption costs
2 million exec * 1 second = 2 million seconds128 MB / 1024 MB = 0.125 GB0.125 GB * 2 million seconds = 0.25 million GBs0.25 million GBs – 400000 GBs = 0 GBs0 million GBs * 0.000016 $/GBs = 0 $
Execution costs
2 million exec - 1 million exec = 1 million exec 1 million exec * 0.20$ = 0.20$
#4... This is the end!
😻Easy to build & deploy
Various languages supported
Lot of triggers available
Inter-connectable in- & outside of Azure
Cost effective
