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

What SQL Database needs

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)

Serverless as glue

Choose your abstraction

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

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

What is Azure Serverless A serverless nirvana? Microsoft Azure CTO Mark Russinovich on the future of the cloud https://www.geekwire.com/2017/serverless-nirvana-microsoft-azure-cto-mark-russinovich-future-cloud/

Functions

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

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

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

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

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

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

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

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

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.

Logic Apps

Shared with Functions Serverless App Service based Triggers (templated)

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?)

Logic Apps Connectors (120+)

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

Workflow Definition Language “Code Behind” Basic Structure

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 https://azure.microsoft.com/en-us/pricing/details/logic-apps/ ACTIONS EXECUTED PER MONTH PRICE PER ACTION EXECUTION First 250K actions €0.000675/action 250K–1M actions €0.000338/action 1M–50M actions €0.000127/action 50M–100M actions €0.000076/action 100M+ actions €0.000046/action

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

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
