Azure Functions - Get rid of your servers, use functions!
1 like820 views
The document discusses the transition to serverless computing using Azure Functions, highlighting its benefits such as automatic scaling, various programming languages support, and a range of integration triggers. It provides scenarios for practical applications like creating HTTP endpoints, connecting services, and image resizing, along with cost analysis for function execution. The presentation emphasizes the ease of building and deploying applications on this serverless platform and concludes with a call to embrace the technology.
![“[…] 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.”

Azure Functions - Get rid of your servers, use functions!
- 1. Get rid of your servers! Use functions☁ + </> = 👊 Manuela Rink Technical Evangelist @
- 2. #0 The Theoretical Part* *no excuses – first part needs to be theory!
- 3. Transformation from own “iron” to cloud VMs
- 4. Transformation from VMs to microservices / functions
- 5. We’ve come a long long way togetherThe cloud evolution
- 6. Serverless or Jeff* or “just the next pig which is chased through the village?” * Serverless is just a name, Paul Johnston
- 7. “[…] 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.” -- Wikipedia https://en.wikipedia.org/wiki/Serverless_computing
- 8. “Quick and easy run pieces of code* in the cloud, without worrying about infrastructure or maintenance.” -- Manu Rink, 2016 *of various size

- 16. #2 Building the real stuff*! … in 3 stages *finally!
- 18. Scenario 0 The Easy Cake use HTTP trigger to provide HTTP endpoints to build an “Is the cake a lie?” service
- 19. Scenario 0 – Easy cake! – Simple HTTP endpoint
- 21. Scenario 1 Connect all the things! use web hooks for wiring up heterogeneous services to connect Slack with your mobile backend
- 22. Scenario 1 - Connect all the things! – Slack & mobile backend The Serverless Connector - Use Functions to write Slack posts in your mobile backend
- 23. Y A X B Connect all the things! LIVE DEMO
- 24. Scenario 2 Like a pro! use Blob Trigger to let function react on storage I/O of other function to build an image resizing service
- 25. Scenario 2 - Like a pro! – Image Resizing Service
- 26. Scenario 2 - Like a pro! – Image Resizing Service

- 29. #3 a Penny saved is a penny goT* *’nuff said!
- 30. Cool stuff so far … and the costs?
- 31. It’s free* *for the 1 million executions and the first 400.000 GB/s
- 32. 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 seconds 1536 MB / 1024 MB = 1.5 GB 1.5 GB * 2 million seconds = 3 million GBs 3 million GBs – 400000 GBs = 2.6 million GBs 2.6 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 seconds 128 MB / 1024 MB = 0.125 GB 0.125 GB * 2 million seconds = 0.25 million GBs 0.25 million GBs – 400000 GBs = 0 GBs 0 million GBs * 0.000016 $/GBs = 0 $ Execution costs 2 million exec - 1 million exec = 1 million exec 1 million exec * 0.20$ = 0.20$
- 33. #4 ... This is the end!
- 34. 😻 Easy to build & deploy Various languages supported Lot of triggers available Inter-connectable in- & outside of Azure Cost effective
