background


Explosion of the Cloud Ecosystem

Cloud computing has enabled a huge ecosystem of services and providers.

Cloud can/has/will easily enable some of the main pillars of delivering IT services
Software (Services)

Artificial Intelligence

Databases

Workflow

Business Intelligence

Mobile

Infrastructure

Scalability

Business continuity



Business

Fail fast with minimal
collateral damage
High availability

Faster time to market
Reliability

Expanded capabilities
Serverless Functions?

A service that wakes up on events, loads and executes
a block of code then gradual decommission itself.
Listen for
Event
React to
Event
Deprovision
Function
Provision
Function
Serverless Functions

Once the service is provisioned* it will load the code
associated with the service, execute, and return a result
to the caller
Load
Code
Provision
Function
Execute
Code
Return
Result
So why is this cool?

Reason for cool factor:

We are using Azure -> (software, infrastructure & business)

Discoverability

Reusable

Fast development, ramp up time

And we pay (¢) just for execution time !!!!!!

Leveraging Azure Functions with
SharePoint

Formula 0 - (SPO + AzFn = Solution)

Azure Functions can be triggered based on:

Timer

Events

Azure Storage (Blobs, Queues, External File, External Table, Azure
Table Storage, Azure DocumentDB, Azure Moble Table Record,
Bot Framework, etc)

Web (Web Hooks, Web Services, & Rest APIs)
Scenarios of Usage
 Auto
Image Tagger (InstaTag)
 Currency Conversion
Auto Image Tagger = SP + AzFn + AI
“A.I. what is that a picture of?”
Mountain on tatooine
!@#!@#
Mountain
24.2 km
Usage: Auto Image Tagger

Formula –> Image Auto Tagging = SPO + AzFn + AI

Use Case: Tag images with keywords

Goal: Improve the findability images and pictures.

Business Issues and pain points:

To much work tagging/updating attributes

I can’t find anything!

SP is just a big file share 

Tagging is not my job !

 Utilization is down because we have required field on upload
Auto Image Tagger

A.I. to the rescue – Once again thanks to the diverse ecosystem of
hosted and cloud services A.I. platforms are easily accessible.

Formula Components

SP = SharePoint Image Library

AzFn = Azure Function (the new Timer Job)

AI = Azure Cognitive Services
DEMO
Auto Image Tagger

What’s Happening?
SP - Currency Converter
Of course we can do currency
conversion in SharePoint …
There’s a currency field right
????
Over promising Oliver
Usage: Currency Conversion

Formula –> Currency Conversion = SPO + AzFn + Flow

Use Case: Users want to enter their sales in their local currency.
Management wants all numbers reported in USD.

Issues and pain points:

Yes a workflow can be used, but logic becomes difficult

Decouples the dependency on SP workflows

Off load processing from your SP environment to another resource

Custom business rules can be supported in AzFn.

AzFn can be reused by other services

Data is maintained in a Storage table (might be some performance gains)

…
Currency Conversion - Architecture
Currency Conversion – MS Flow

IFTTT/Connector/Workflow service

A plug and play service that connects to MS applications to other
3rd services

WITHOUT CODING (SORT OF)!
MS Flow – Custom APIs
Can reference other services
with Custom APIs
But you need a little swagger!!!
MS Flow – Custom APIs
Custom API form
BTW don’t forget about the
name at the top!!!
MS Flow – Flow Currency
Conversion
Hook into a SharePoint list event
Start flow when list item is
created
