Top Office 365 + Azure scenarios

What? How?

Do something on a schedule Put code in Azure Web Jobs/Functions

Build apps (Office 365 app/SP provider-hosted add-in)

Deploy app files to an Azure app

SharePoint site provisioning Deploy PnP Partner Pack to Azure

Run code on a button click Use Azure Functions + JavaScript

Store data not suited to SP lists Use Azure SQL Database

Store files for my app Use Azure BLOB storage (and CDN if appropriate)

Implement SharePoint web hooks Use Azure Queues and Functions

Implement authentication on a custom web app

Implement Azure Active Directory (AAD) auth

Or the general case:

HOST MY REMOTE SHAREPOINT CODE!

•93% revenue increase YoY

•2x compute usage YoY

Web Apps

A great hosting location• Easy to manage, scale up/down

• Auto SSL/load-balancing/backup

Perfect for extending SharePoint• Office 365 apps

• SharePoint Add-ins

• Standalone web apps

Create Azure web app

Register app in AAD/SP

Configure Deploy files

Deployment options

Drag and drop in browser (Kudu)

Publish from Visual Studio

WebDeploy

Source control integration (GitHub, Git, VS Online)

FTP

Azure Web Apps - deployment slots

Dev/test/prod “instances” of your site • Own URL

• Own App Settings/Connection Strings

http://mysite.azurewebsites.net

http://mysite-dev.azurewebsites.net

http://mysite-test.azurewebsites.net

Allows you to test purely in production Office 365 environment, BUT with dev/test/prod code!

In Azure

portal:

PowerShell:

“Swapping” deployment slots

Slots can be swapped to deploy updates

Actually a DNS update, not copy of content

Process:Publish updates to dev/test slots

Swap test/production when ready

Switch-AzureWebsiteSlot–Name ‘COB website’ -Slot1 'Production'-Slot2 <slotName>

More Azure coolness – “Testing in production”

Traffic Routing - send some traffic to another slot

Uses:Testing new functionality on small number of users

A/B testing

What is App Insights?

Azure-based monitoring/reporting of your app

• Exceptions

• Events within your app

Basic page analytics

• (Not really suitable for site owners)

Free up to 20GB per month

Getting started

ASP.NET web app

• NuGet package:

Install-Package Microsoft.ApplicationInsights

• https://www.nuget.org/packages/Microsoft.ApplicationInsights/

Modern web app

• npm package:

npm i applicationinsights

• https://www.npmjs.com/package/applicationinsights

Instrumentation key

Links your code to App Insights instance:

Log custom events/metrics

How long does a (Graph?) API call take *for the user*?

How often did a user click button X?

What are the most popular file types?

Simple code hosting

Scenarios• Button click (e.g. web part)

• Scheduled process

• Respond to event (e.g. new file in Azure)

Develop in any language• C#, JavaScript, PowerShell etc.

Simpler than a Web Job or Web API!

Functions – pricing plans

App service plan Consumption plan

Runs on dedicated VMs Serverless

Pay for containing VM Pay for what you use (executions)

Great if running at high scale Great for intermittent/quicker jobs

Scale at VM level Scale up automatically

MORE EXPENSIVE CHEAPER

So, generally you want the consumption plan!

Functions vs. Web Jobs

Similarities• Both can be scheduled or use trigger (queue/BLOB

etc.)

• Both support C#, JavaScript, PS

Differences• Pricing - only Functions have pay-per-use option

• Flexibility - Functions can be triggered from HTTP call/web hook, OneDrive, Github etc.

• Restrictions – max 10 min timeout on Function

Typically Functions > Web JobsSee http://cob-sp.com/2r1MZe5

Authentication options

Function auth• A simple code passed to function

• Caller must know/store the code

• Auth to Office 365/SP handled separately

Azure AD auth• Function cannot be called without auth token

• Requires adal.js/msal.js from JavaScript OR cookie/IFrame approach (currently)• OpenID Connect may help in SPFx in future?

Options for developing Azure Functions (C#)

Use Azure portal

• Good for playing around

• No source control

• Little coding support

Use VS Code

• Sync from source control to Function

• Little coding support for C# (more for node.js)

Use Visual Studio 2017

• Full coding support (F5 debug, IntelliSense)

• Publish to Azure

• Requires VS2017 15.3+ with Azure development workload

.csx files and #r references True C#

Azure Functions in the real world

Secured by AAD auth

Identity of current user available if required

Use of NuGet packages

Uses App Insights for monitoring

Uses PnP Core

Callable from SPFx (with adal.js or cookie method)

Stop storing things in SharePoint that should be in SQL!

Benefits

Get started faster than on-prem

Don’t worry about

backups (or patching)

High availability

Data replicated

to 3 servers

Pricing:

- Free up to 20MB

- Pay for data used

Azure SQL DB sizes

SQL in an Office 365 world

Can now auth with AAD identity • No need for separate SQL

auth/identity• Best practice – set AAD Group, not

User to be admin

Code options• Connect with certificate – app-only

auth• Connect with user token (using

MSAL or ADAL) – user auth

Create a new DB/add item with EF

Entity Framework code: using (var db = new ListDbContext())

{

List list = new List();

list.ListId = Guid.NewGuid();

list.WebId = Guid.NewGuid();

list.SiteId = Guid.NewGuid();

ListItem item = new ListItem();

item.List = list;

item.ItemUniqueId = Guid.NewGuid();

item.Id = 1;

db.Lists.Add(list);

db.SaveChanges();

db.ListItems.Add(item);

db.SaveChanges();

}

ARM templates

Easily deploy without button clicks!

Defined in JSON, deployed with PowerShell (or C# etc.)• Parameters extracted to separate file

Deploy entire app, and optionally resources (e.g. code):• Web app (inc. App Settings, SSL cert etc.)

• SQL Database

• Function app

• etc.

New-AzureRmResourceGroupDeployment–TemplateFilexyz

Building an ARM template

• The scope is a Resource Groupodreason to structure your resources in this way

• Export-AzureRmResourceGroup

• See https://azure.microsoft.com/en-us/blog/export-template

ARM templates – commandsNew-AzureRmResourceGroupDeployment

-ResourceGroupName foo –TemplateFile app.json-TemplateParameterFile params.json- Mode Incremental

Test-AzureRmResourceGroupDeployment–TemplateFile xyz

New-AzureRmResourceGroupDeployment-ResourceGroupName foo –TemplateFile app.json-TemplateParameterFile params.json- Mode Incremental

Advanced ARM scenarios

Auto-deploying files for web app/Function• Zip file must exist in Azure BLOB storage

• Auto-deploying SSL certs• Fetch bytes from filesystem, use in parameters object

ARM templates – other features

Define dependencies, for

correct provisioning sequence

Tags

Role-based security

Queues are great for..

Anything that should be picked up by a longer running task• SharePoint site provisioning

• SharePoint web hooks

• File processing (e.g. my image renditions demo)

QueueTrigger – the key• Auto-runs your code (when new item added)

• Azure Function

• Azure Web Job

Decoupling code with a Queue

I take things from queue and process them e.g.- Azure Function- Azure Web Job

I put things on queue

QueueTriggerC#, REST etc.

What goes on a Queue?

Answer – a string (i.e. anything)

{“SiteUrl”: “/Project12345”,“Title”: “Project 12345”,“Template”: “ProjectSite”“Owners”: {

“Primary”: “chris.obrien@foo.com”,“Secondary”: “adam.smith@foo.com”}

}

Create object

Serialize

Add to queue

Adding a queue item// Retrieve storage account from connection string.

CloudStorageAccount storageAccount = CloudStorageAccount.Parse( CloudConfigurationManager.GetSetting("StorageConnectionString"));

// Create the queue client.

CloudQueueClient queueClient = storageAccount.CreateCloudQueueClient();

// Retrieve a reference to a queue.

CloudQueue queue = queueClient.GetQueueReference(“SiteRequestQueue");

// Create a message and add it to the queue.

CloudQueueMessage message = new CloudQueueMessage(siteInfoObject);

queue.AddMessage(message);

Other ops:

- Peek message

- Dequeue message

- Amend contents of existing message

Storage Queues vs. Service Bus Queues

Be aware of the two options..

..but Storage Queues work well for most

Key differences:

Storage Queue Service Bus Queue

7 day max lifetime Unlimited lifetime

Full transaction log No transaction log

Order not guaranteed Order can be guaranteed

Potential duplicates Duplicate detection

Simpler More complex

AzureQueues

And we didn’t even talk about…!

Azure Containers (Docker)

API management Virtual machines (of course!)

Azure RMS Azure B2C Azure mobile apps (e.g. notification hub)

HDInsight Azure Data Lake Azure virtual networks

Azure media services

Azure batch (HPC) Azure backup vault

Key take-aways

Web apps are cooler than you think!

Write your first Azure Function!Perfect for timer jobs, perfect for web APIs (e.g. advanced web parts)

Try deploying the PnP Partner Pack as a good exercise (manual approach)
