Today’s Goal
Cover key development patterns and
practices that will help you build real
world cloud apps
Dev/Ops Workflow

Repeatable
Reliable
Predictable
Low Cycle Time
Source Control
•
Use it! 
•
Treat automation scripts as source code and version it
together with your application code
•
Parameterize automation scripts –> never check-in secrets
•
Structure your source branches to enable DevOps workflow
Example Source Branch Structure
Master
Staging
Development
Feature
Feature
Branch A Branch B
Code that is live in production
Code in final testing before production

How We Did It
Code and debug for weeks (months?)
Build on one person’s machine
Manually deploy parts via file copy
Run manual tests against deployed app
How We Did It…Which Resulted In
Code and debug for weeks (months?)
Infrequent releases reducing business agility
Build on one person’s machine
Inability to reliably reproduce builds
Manually deploy parts via file copy
Tedious and error-prone due to missing dependencies
Run manual tests against deployed app
Code and debug for weeks (months?)
How can we do it?

Continuous Integration & Delivery
•
Development, Staging and Master branches kick off
•
Use automation scripts with Development and Staging to
automatically deploy to environments
•
automated build + check-in tests
Deploying Master to Production can be automated, but
more commonly requires an explicit human to sign-off
before live production updated

Windows Azure Web Sites

Build with ASP.NET, Node.js, PHP or Python

Deploy in seconds with FTP, WebDeploy, Git, TFS

Easily scale up as demand grows
AutoScale – Built-into Windows Azure

AutoScale based
on real usage
CPU %

Queue Depth
Supports
schedule times
Web Development Best Practices
•
Scale-out your web tier using stateless web servers
behind smart load balancers
•
Dynamically scale your web tier based on actual usage load
•
Avoid using session state (use cache provider if you must)
•
Use CDN to edge cache static file assets (images, scripts)
•
Use .NET 4.5’s async support to avoid blocking calls
Windows Azure AD

Active Directory in the Cloud

Integrate with on-premises Active Directory

Enable single sign-on within your apps

Supports SAML, WS-Fed, and OAuth 2.0

Enterprise Graph REST API
Data Storage Options on Windows Azure
Platform as a Service
(managed services)
Infrastructure as a Service
(virtual machines)
Understanding the 3-Vs of Data Storage
Volume
How much data will you ultimately store?
Velocity
What is the rate at which your data will grow? What will the usage pattern look like?
Variety
What type of data will you store? Relational, images, key-value pairs, social graphs?
Scale out your data by partitioning it
Vertical Partitioning
Horizontal Partitioning (Sharding)
Hybrid Partitioning
It is a lot easier to choose one of these
partitioning schemes before you go live….
Blob Storage
Process automation that simplifies cloud
management
Optimize and extend
existing investments
Integration
Integrate into existing systems
with PowerShell integration
modules
Build additional PS modules to
enable integrating into other
systems
Deliver flexible and
reliable services
Lower costs and
improve predictability
Orchestration
Accelerate time to value
with flexible process
workflows
Improve service reliability
across multiple tools,
systems, and department
silos
Automation
Enable service owners to focus
on work that adds business
value
Reduce error-prone manual
activities while lowering costs
Azure Automation Capabilities
Runbook Authoring in Azure:
Create runbooks to automate all aspects of
cloud operations, from deployment,
monitoring, and optimizations
Highly Available Engine:
Support requirements for scale and H/A.
Built on PowerShell Workflow. Isolation for
runbook jobs
Integration into other systems:
Import PS modules and create additional
modules and runbooks for Azure services or to
connect into 3rd party systems

Buy/Rent a Telemetry Solution
Application
Insights
Application Insights
1. Telemetry is collected at each
tier: Mobile applications, server
applications and browser
2. Telemetry arrives to
Application Insights service
where it is processed & stored
3. Get 360° view of the
application covering availability,
performance & usage
Telemetry for 360° view

Observed application behavior
5
Infrastructure performance
URL pings and web tests from 8 global points
of presence
How is the application being used?
Whatever the developer would like to send
to Application Insights
No coding required – service dependencies,
queries, response time, exceptions, logs, etc.
