Download as PPTX, PDF1 like741 views
This document provides an overview and summary of Azure Logic Apps and API Apps. It discusses how Logic Apps allow users to easily automate business processes across Software as a Service (SaaS) applications and on-premises systems using a visual no-code designer. It also describes how API Apps make it simple to build and consume APIs in Azure. The document highlights some of the key capabilities and built-in connectors for Logic Apps, and tools for developing APIs in API Apps using Visual Studio. It provides a comparison of features between Logic Apps and the previous BizTalk Services offering.
![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()])"](https://image.slidesharecdn.com/baug-logicapps-dan-slideshare-150513112714-lva1-app6892/85/First-Look-at-Azure-Logic-Apps-BAUG-33-320.jpg)

- 28. Architecture The 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!
- 29. 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
- 30. … 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
- 32. 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
- 33. 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()])"
- 34. 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
