Key Learnings

• Validated the brand & cloud design patterns

• Hybrid is critical & a differentiator

• Feature & capability gaps:

• Out of box sources & destinations

• Pipeline templates, custom code support

• Long running workflows, parallel execution

• Needs a lot more investment!

ArchitectureThe Azure Resource manager is a highly-scalable geo-distributed system that handles millions of resources across 100,000’s of subscriptions. Can

create 200 node cluster in < 5 minutes!

Same underlying engine…

Resource Manager

• Can handle thousands of parallel deployments per stamp• Resilient against failure – retries

with “at least once” guarantee• Simple, declarative JSON template• Automatically infers dependences

between resources

Logic Apps

• Can handle thousands of parallel runs per stamp• Resilient against failure – retries

with “at least once” guarantee• Simple, declarative JSON

definition• Automatically infers dependences

between actions

… more power

Resource Manager

• 8 functions for basic referencing and string functions• Can only PUT resources into

resource groups• Auth must be through AAD• Triggered manual through UI or

API

Logic Apps

• Over 50 functions from string manipulations to math, to sets operations, to logical operators• All HTTP operations supported on

any arbitrary endpoint• Supports many OAuth providers,

AAD, Cert auth, or Basic auth• Different ways to be triggered

including recurrence

demo

Logic apps for orchestration across API apps

1. Implicitly – whenever you reference the output of an action you’ll depend on that action executing first

2. Explicit “dependsOn” condition – you can mark certain actions to run only after previous ones have completed

3. Explicit “expression” condition – a complex function that evaluates properties of other actions

Repeating

• Loop a single action over a list of items• Runs the action N times• You can get at all of the statuses for each action• Tip: when you have multiple collections use:

• "repeat" : "@range(0,length(body('connector1')))"• …• "inputs" : "@concat(body('connector1')[repeatItem()],

body('connector2')[repeatItem()])"

Conditionals

• Logic on a trigger or action• For triggers conditionals are post-conditions• For actions conditionals are pre-conditions

• You can do conditionals inside of repeats to perform as a filter

{ "parameters": { ... }, "triggers": { ... }, "actions": { ... }, "outputs": { ... }}

Target audience is anyone who can use Azure

… but not necessarily business users or consumers
