Azure Functions e Logic Apps I tuoi coltellini svizzeri per gestire i tuoi dati in un SQL Database

3. @marco_parenzan
.NET, IoT and Azure Developer, Trainer and Consultant Microsoft MVP 2017 for Azure Book Packt, LSWR Community Lead per 1nn0va

4. What SQL Database needs

5. What SQL Database needs
SQL Database is Database as a Service
It is only the database
Vs. SQL20xx
Almost language syntax aligned
Deprecated features
Migrate features to External/Other Azure Services
Overlapping features (ex. JSON)

6. Serverless as glue

7. Choose your abstraction

8. Serverless manifesto
Function are the unit of deployment and scaling. Scales per request Users cannot over- or under-provision capacity. Never pay for idle (no cold servers/containers or their costs) Trigger-based invocation code run because of an event happened and has to be handled

9. Serverless as a bridge for SQL Databases
Import/Export Other data formats Data manipulations Schedules Other Azure services bridges

10. What is Azure Serverless
A serverless nirvana? Microsoft Azure CTO Mark Russinovich on the future of the cloud

11. Functions

12. Azure Functions
Process events with Serverless code. Make composing Cloud Apps insanely easy Develop Functions in C#, Node.js, Python, PHP, Batch and more Easily schedule event-driven tasks across services Expose Functions as HTTP API endpoints Scale Functions based on customer demand

13. Azure Functions architecture
Azure Functions is built around the WebJobs SDK runtime. The WebJobs SDK makes it easy to react to events and work with data in a consistent abstracted fashion.
App Service Dynamic Runtime
WebJobs Core SDK
WebJobs Extensions
WebJobs Script Runtime
Triggers
Inputs/ Outputs
Language Abstraction
Code
Config

14. Platform and scaling
App Service offers dedicated and consumption tiers.
Dedicated is the existing App Service plan tiers
Basic, Standard, Premium
Pay based on # of reserved VMs
You’re responsible for scale
Consumption (Dynamic)
Pay per execution model - two meters, three units
Number of executions
Duration of execution x reserved memory

15. Supported bindings Type Service Trigger Input Output Schedule
Azure Functions ✔
HTTP (REST or WebHook)
Blob Storage
Azure Storage
Queues
Tables
No-SQL DB
Azure CosmosDB
Streams
Azure Event Hubs
Push Notifications
Azure Notification Hubs
IoT
Azure IoT Hub

16. Supported Languages 1st class support Experimental support
Node/JavaScript
C# (.NET Framework 4.7.x) F#
Experimental support
.NET Core
Linux Containers
Java
Python
PHP
Batch
Bash
PowerShell

17. Developing Functions
Portal Local runtime Visual Studio 2017 Visual Studio Code Windows (.NET 4.6.1) 1.0 Windows/Linux (.NET Core 2.0) 2.0

18. Functions Programming Model
Trigger
(data)
Input
Input
Input
Output
code
Function as a single unit of work Functions are executed per trigger Functions have inputs and outputs
Output

19. Durable Functions
Enable “long running” functions while maintaining local state. Simplify complex Function coordination (chaining, etc.) Easily call a Function from another Function All of the above using code-only

20. Functions and Logic Apps
Functions and Logic Apps work great together and that integration will only get better.
You can orchestrate Functions using Logic Apps today.
Durable Functions overlaps with Logic Apps, one function calling another, but:
Offers advance ‘code only’ orchestration ‘like’ capabilities to function
Enables "long running" functions
Enables "advance" scenarios/patterns which are difficult otherwise: async HTTP, map reduce, actors, etc.

21. Logic Apps

22. Shared with Functions
Serverless App Service based Triggers (templated)

23. Unique for Logic Apps «Older»/Mature(?)
Implement and orchestrate visually designed integration workflows
Orchestrate distributed microservices
Or Functions
Every action is a an http endpoint
Connectors
Declarative
No code designer for rapid creation (mostly?)

24. Logic Apps Connectors (120+)

25. Concepts
Simple-to-advanced flow control like conditions, loops, exception handling, and parallel
Multiple Patterns
Manual Invocation
Event Based
Scheduled
Workflows
Triggers
Actions
Managed APIs
Flow structures

26. Workflow Definition Language
“Code Behind” Basic Structure

27. Pricing
Different billing model from Function App No App Service Plan  Per action (each step in a Workflow is an action, also a trigger) More details
ACTIONS EXECUTED PER MONTH
PRICE PER ACTION EXECUTION
First 250K actions
€ /action
250K–1M actions
€ /action
1M–50M actions
€ /action
50M–100M actions
€ /action
100M+ actions
€ /action

28. Scale & Performance Different billing model from Function App
100MB message size 90 days run duration 1 sec to 500 days recurrence interval 100’000 ForEach items 10’000 actions executions per 5 minutes
Request Timeout
120 Seconds
Run duration
90 days
ForEach items
100,000
Actions executions per 5 minutes
Actions per workflow
250
Allowed action nesting depth 5
Triggers per workflow 10

29. Why do we need “Durable Functions”
Enable “long running” functions while maintaining local state. Simplify complex Function coordination (chaining, etc.) Easily call a Function from another Function All of the above using code-only
