I have an application that uses the Azure database and I would like to make my application fire a notification when certain things in this database change, I think the correct way to do this is using Azure Notification Hub, but... no I find a way to connect it with Unity, Is there a way?, if not... Is there a way to achieve what I ask?, thanks.

I am having trouble to identify the best "tool" to solve the problem. I am using a python library which publishes to its data via Sever-Sent-Events (SSE) (see https://github.com/wattsight/wapi-python/blob/development/wapi/events.py).
I would like to constantly listen for new events. However, I am not sure which tool in Azure in appropriate. An Azure Function would have to run continously which seems like a misuse, SignalR requires control over the "sender" of events and I don't know if EventHub would be able to manage that job.
Thank you for letting my learn from your experience.
The azure Eventhub is the right service to receive new events. Besides that, it can also provide other benefits like scalability, events storage etc.
And you can also consider using azure function with eventhub trigger. But it has a limitation about the incoming message max size.
We are designing synchronization between SAP and Salesforce.
Our architect propose pattern to use Azure Service Bus between them:
Our client want to use Azure Event Hub instead Azure Service Bus for this.
And client told us, that Event Hub is must have for that.
Reading documentation in my opinion Azure Service Bus should better fit for synchronization like Point-to-Point (from SAP database to Salesforce database).
Can somebody explain, why Event Hub can be better for synchronization like this?
What is good point for our client to use it?
Should we try to convince our client to change architecture to Service Bus?
I really didn't made integration using Event Hub so I don't know what should I expect for that.
In my python application, if any bad/good event happens, I want to send the event details as notification message to user's email addresses or phone #s that have been subscribed to this application. So I am looking for publisher-subscriber model azure cloud
Looks like multiple Azure services achieving similar goal but having a thin line of differences. Event hubs and notification hubs seems promising. So my question is as follows:
Can email ID/phone # be subscribed to Azure event hub and receive the message being sent/produced to Azure event hub?
If not event hub, what is the correct option? Can I achieve it with Service bus or Notification hub?
In AWS, there is a service called SNS (Simple Notification Service) where one can subscribe email/phone number and opt for receiving event messages about that application. I am looking for equivalent to that in Azure.
You can use the Azure Logic Apps / Azure Functions with Event Hubs to achieve this easily.
Using logic apps you can do like simple as below image.
Logic Apps has many in-build connectors for most all Azure Services, you can use Event-hubs,Service bus,SQL etc.,
You can find all the list of available connectors here
Update 1
Once you connected the Event-Hubs to send an Email connector, you will automatically get all the available source data from event-hubs to email task. See below
You can achieve this by using Azure Application Insights. With this, you will be able to monitor your application and receive alerts during application unavailabillity, failures or even during performance issue.

I'd like to build a small solution on Azure for practice. I'd be sending data using IOT-HUB from some devices and what I need is some way to interpret this data and do appropriate query to Azure SQL.
Basically I would need a way to have my program running all the time being able to:
listen to events from iot-hub
interpret event information and save/get data to/from database
send a message to some device using iot-hub
Which service would be good for that? Am I able to use Entity Framework?
In ideal solution I'd create a C# program to do what I need and have it running in Azure, waiting for events from iot-hub, having access to my database - is it even possible?
I'm very new (rather completely new) to cloud solutions, so I'd be really grateful for any advices. Currently I feel completely lost in all these Azure services.
There is quite some documentation on Azure IoT and how one can possible architect an IoT solution.
The IoT documentation is the obvious first step to get an overview of what Azure offers. There are some nice 'Getting Started' walkthroughs also
Take a look at this IoT reference architecture. Quite helpful to get an overview.
There are tons of links and interesting examples for Azure IoT. Just google around.
I have a static dot net web application with application insights sdk. How do I send application insights data to Azure Event Hub? I have successfully used the Azure Continuous Export feature but I would rather like to send the telemetry data to the Event Hub.
To explicitly send data to eventhub you will need to use EventHub SDK, which is currently available in .NET/C#, Java, REST, and Node.js. For your case which is a web application, sending via REST APIs might be the easiest way. Take a look at API reference for more information: https://msdn.microsoft.com/en-us/library/azure/dn790674.aspx
One catch is that receiving events is not currently supported using REST, you would still need a .NET or Java application to be on the receive side.
If you are looking for a common logging framework - which can be configured to send data to "whatever data destination" you want to - you should consider looking at log4net.
Here's a good implementation of log4net-appender for EventHubs.
#greypanda,
As you know Continuous Export currently only exports Application Insights to blob storage, from which you can pick up the data for use in any workstream you want. Exporting directly in an Event Hub is something that could be a future feature, so please log this at our UserVoice site: https://visualstudio.uservoice.com/forums/357324-application-insights.
We will also have a set of REST APIs for Application Insights soon (see https://visualstudio.uservoice.com/forums/357324-application-insights/suggestions/4999529), which might help you.
I would like to learn more about your scenario so I can better help you in this instance and improve our export and API features. Feel free to reply here or if you want, shoot me a mail offline.
Thank you

We don't really support that. It's a lot easier to let the SDK send the data to App Insights portal, then you can use Continuous Export to move it out into Storage. If you want, you can use Stream Analytics to move it from there.
What do you plan to ultimately do with the data? (I mean, why event hub...?)
