- 6. Key Questions Any Flow showstopper ? Do I need to use a third party tool ? Robust ? Very easy ? Expensive ? Here is our experience after 3 years and 9 enterprise flow projects…
- 10. Create REST Services (like Azure functions) Create Custom Connectors Call REST APIs from Flow Integrate Flow in their Applications Developers Activities Requires P1Requires P1
- 14. Key Flow Limitations State machine pattern or Controller patternNo State Machine No custom task forms Max 5,000 iterations in Do until –> Create embedded loops Max 5,000 iterations in For each (100,000 in Plan 1) Loops Create nested flows or raise a ticket250 actions/flow Flow Approval duration : 30 days Flow duration : 30 days No guest access Controller pattern In the roadmap for Flow & PowerApps ALM/devops weak I could tell you, but then I would have to kill you… Custom approval actions Cannot resume flow In the roadmap
- 15. Boss validates the final document Secretary validates style Advisors validate content User Publishes a new “legal” document Why State Machine ?
- 16. State Machine and > 30 days « Flow Controller Pattern » Controller Launcher flow SecretaryAdvisor Boss escalate timeout approved rejected in vacation timeout approved rejected redirect in vacation timeout approved rejected escalate Normal flow Service flow
- 17. 3 Implementations Messages (Service Bus) Database (SQL Azure) Http & Request (Requires P1 license !) Requires P1
- 18. Demo: Approval escalation Approval analytics Controller pattern Machine Learning
- 20. Started from Excel Started from SP New Expense from App Trigger : Excel for a selected row Trigger : SharePoint for a selected row Existing Expense from App Trigger : SharePoint : when an item is created Proxy Flows Service Flow Trigger Agnostic Pattern
- 22. Protect your flow service url with Azure API Management service • the url might change, we want to use a stable vanity url like https://flowdemo.azure-api.net • you might need to protect it : authentication • throttling • restricting the callers to some specific network locations • ….
- 23. Working with large datasets : Pagination Returns max 2048 records
- 24. Working with large datasets : Pagination Returns max 5000 records or 100.000 if P1 licence $skiptoken=Page=TRUE%26p_ID=3000&top=5000
- 27. Adapt retry policy Reduce flow concurrency Use several connectors Error HTTP 429 : « I’m too busy » come later (in 10 sec) Flow throttled by the Service (like SharePoint) and by the Connector (600 calls/min) Throttling
- 28. 202 ACCEPTED The request has been accepted for processing, but the processing has not been completed. Long Call Duration Pattern Requires P1

- 33. Conclusions
- 34. Conclusions You can, but it will be much much more expensive Do I need to use a third party tool ? Is it robust enough for enterprise business processes ? Is Flow is very easy to use and not expensive (Office 365 license) Easy : Yes but it sometimes requires “advanced” skills Cheaper than anything else but be careful with P1 Very robust engine (Logic Apps) – we’ve tested it on thousands of flows 24x24x365 Reliability depends on the connector and on your architecture Error handling and Flow monitoring Start with Flow in a first place, your prototype might survive
- 35. Conclusions I ALWAYS define UML Use Cases I often define UML Activity Diagrams I often define RACI matrices (Responsibility assignments)

- 39. Use Case Diagrams • Used during requirements elicitation to represent external behavior • Actors represent roles, that is, a type of user of the system • Use cases represent a sequence of interaction for a type of functionality; summary of scenarios • The use case model is the set of all use cases. It is a complete description of the functionality of the system and its environment Passenger PurchaseTicket
