I'm trying to figure out if Azure Blob Storage has similar functionality to Amazon S3. An S3 bucket can be configured in a way, that when new object is created, bucket sends message to SQS. I'm wondering if Azure Blob Storage is able to do the same with Azure Service Bus (which is kind of similar to SQS, correct?).
The only resource I've found so far, which mentions something similar is https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview, but there is no Azure Service Bus on the right side. I know I can use Functions as a proxy, but I'm interested in direct connection.
Any ideas?
Service bus(I think you compare service bus with SQS and SNS in AWS) don't have the ability to subscripe to Blob storage events. Event Grid(the link that you reffered to has Service bus support on the roadmap but no date is confirmed.
I think your best choice is Azure Functions(or Logic app if you don't want to write code) that has a blob Storage trigger to catch events and do action X.
https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-storage-blob-triggered-function.
Or wait a litte for event grid but you still get that "proxy" part.
One option is to use logic apps/ event grid and you can add trigger directly from azure blob storage (https://azure.microsoft.com/it-it/blog/azure-service-bus-now-integrates-with-azure-event-grid/) . Another option would be to add blob trigger with azure functions and write the code to do whatever action which you are looking for .

I want to move events from azure event hub to Azure blob storage using the logic app, can anyone suggest to me how to use with logic app connector, triggers, and action with the designer example.
Note:
Events are json events and need to be stored in blob storage.
You can start with a blank logic app, and use the search assistant to find what you're looking for.
Typing event hub gives:
where you can provide the connection by providing the name.
Save the content in a variable.
You can use SaveInitialJsonToBlobStorage to now store this json in a blob storage:
When handling an Event Hub event with an input bound Azure Function, is it possible to change the Storage account configured for the Event Hub partition checkpointing?
Is it possible to do this with a Premium Storage account and in isolation (ie a different Storage account than the account selected for the Azure Function during set up)?
It seems that this is possible with the EventProcessorHost but the Function doesn't seem to expose the EventProcessorHost configuration.
I did a similar hack for some other propose.
First, stop your Azure function
Then, Create New Premium Storage account and Copy an existing blobs and container (All eventhub checkpointing files with the same folder structure).
Then change Azure function storage account connection string to new premium storage account.
Then start your Azure function.
Is it possible to use some ready made construct in azure cloud environment to ingest the events (in json format) that are currently stored in azure blob storage and have it submit those events directly to azure event hub without writing any (however small) custom code? In other words, I would like to use configuration driven approach only.
Sure. You can try to use Azure Logic Apps to realize your needs without any code or just with some function expressions, please refer to the offical documents of Azure Logic Apps to know more details.
The logic flow is as the figure below.
You can refer to my sample below to make it works.
Here is my sample to receive an event from my EventHub and transfer to Azure Blob Storage to create a new blob for storing the event data.
Create an Azure Logic App instance on Azure portal, it should be easy for you.
Move to the tab Logic app designer to configure the logic flow.
Click Save and Run buttons. Then, use ServiceBusExplorer (downloaded from https://github.com/paolosalvatori/ServiceBusExplorer/releases) to send event message and check whether new blob created using AzureStorageExplorer. It works fine after a few minutes.
I need to move data received in my Service Bus Topic to a Storage Account inside Azure.
I believe Azure Function is one of the good ways to achieve this.
Please share suitable example if you have one.

Fire up an Azure Functions project, create a function with a Service Bus trigger binding (if you're in the portal or Visual Studio then it'll offer you a template) and add a storage output binding for blob, queue or table as appropriate. Then in the function code just copy the relevant data from your trigger parameter to your output parameter.
I have a use case where I'd like to launch a job on an Azure Container Service cluster to process a file being uploaded to Blob storage. I know that I can trigger an Azure Functions instance from the upload, but I haven't been able to find examples in the documentation of starting a job within Functions.
This diagram illustrates the AWS equivalent of what I want:
Thanks!
The Azure Event Grid feature is what you need. It is still in preview, but you can subscribe to the Blob Created event. You can set the subscriber endpoint to an Azure Function that puts a message in a queue to trigger your job, or you can expose a service on your cluster that will accept the request and do whatever you need done.
Microsoft provides a guide at https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-quickstart?toc=%2fazure%2fevent-grid%2ftoc.json#create-a-message-endpoint
