We are building multi-tenant microservices based platform on Azure and we are using service bus for integration between micro-services.
We are receiving input pipeline message from batch and real-time and I want to ensure all tenant message process with equal priority.
pipeline looks like
Note: we are using Azure function to process service-bus messages
below line I got from Microsoft documentation
This fully managed service is available in multi or single tenant
configurations with no servers to manage or licenses to buy.
Can anyone suggest, How to use service bus in multi-tenant scenario? do you think I really need to care if I'm using azure function (azure function will auto scale)?
I want to give equal priority to all tenant.
Thanks #Mikhail, I confused by below statement
This fully managed service is available in multi or single tenant
configurations with no servers to manage or licenses to buy.
Azure ServiceBus Standard run under shared resources while premium runs a dedicated instance of Service Bus.

Team,
I have a complete running cloud service application upgraded to latest Azure SDK version and unfortunately need to dump this into a CSP subscription. But I came to know that Azure CSP supports only the Azure Resource Manager model, the cloud service is a classic deployment model. So we cannot create a cloud service within a CSP subscription.
Is there any other alternative within Azure CSP to using "cloud service" so that we can migrate with minimal changes. Please help
Firstly, here are some good reads on Microsoft Docs to help comparing the options available and make decisions based on your requirements:
(I mean requirements like Hosting features, Service Limits, 3rd party software installation and RDP access is required or not, Network isolation to a separate VNET is required or not, Cost considerations, minimum SLA, Regions available, instant deployment and auto-scaling, state management etc.):
Azure App Service, Virtual Machines, Service Fabric, and Cloud Services comparison
Decision tree for Azure compute services (This one covers a big spectrum.. simple virtual machines, Batch, Functions, Containers, AKS, ServiceFabric)
Criteria for choosing an Azure Compute Service
Also know that when looking for alternatives, it's not uncommon to make use of multiple compute or other Azure service options by breaking up an older solution into parts at the time of such migration (for e.g. A serverless compute option like Azure Function + Service Fabric + something else if needed).
Generally speaking (and without knowing much about your application from your question currently), Azure App Service and Service Fabric could be considerations IMHO when migrating from an existing Cloud Service, but this is exactly where detailed requirements help you in decision making.
On a side note, here is a list of Azure Services available in CSP - Available Azure services in Azure CSP
we are working on an integration with service bus. We don't have an account with azure, so we can't run our own server, but our client does.
For testing purposes, are there any openly available service bus topics I can subscribe to and test our code? the content actually does not matter, we just want to make sure our code can connect and read messages.
If this is not possible, how is the approach for testing our subscription code for azure service bus? Do we need to open a azure account?
thanks!
You do need your own subscription to create and test Service Bus Topics.
To create your free Azure Subscription refer here.
What are the typical use cases for using azure service fabric over azure service bus messaging? Though azure service bus messaging claims to be AMQP 1.0 compliant, I would still be writing to azure's service bus messaging api. In my view, both are platform as a service (PaaS) solutions. I am more interested in why I would use one over the other. Thanks.
These are completely different products.
Azure Service Bus is just an umbrella name for several messaging patterns: point-to-point, publish-subscribe, event streams and notifications. It's PaaS and it's globally available for integration of any applications that are connected to the internet. It does not run any custom code of yours.
Service Fabric is a platform to run your custom services on. You develop a service and then host it in a Service Fabric cluster (Azure is the main deployment option, but on-premise is supported as well). Service Fabric then takes care of things like availability, resource monitoring, state management, live updates etc for your services.
Even though a reliable queue is one of the patterns available in Service Fabric, you can't call it directly from outside of the cluster, so it's more of internal mechanism than integration.
Service Bus and Service Fabric can be used together: ASB for data input and output integration based on messaging, and SF as application cluster.
I am trying to make a hybrid application on Azure which uses both mobile services and a worker role. In a script (Node.js) which runs on mobile services DB, I want to send a message through service bus queue. Then my worker role will receive that message and perform some actions. But I can't find how I should sent the message to service bus queue.
BTW, this is not mentioned in "Mobile Services server script reference". Is it possible at all or not?
Thanks.
This is possible. From your Mobile Services scripts, you can use the Azure module to talk to Service Bus. You can find the reference and source code for the Azure module here: https://github.com/WindowsAzure/azure-sdk-for-node. For an example of using the Azure module (in this case to talk to Blob Storage, but it's useful code to go off of) take a look at this walkthrough: https://www.windowsazure.com/en-us/develop/mobile/tutorials/upload-images-to-storage-dotnet/.
Is there a way to play with and discover Azure Service Bus on the local emulator without registering to the real Azure Services?
I was following a tutorial on the use of the Azure Service Bus but at a certain point a Namespace and an Issuer Name and Key is required. I don't have that data since I'm not registered to Azure Services and I don't want to do it now (I will get my trial when I will feel ready to develop/test something real).
If you want to use the Brokered Messaging capabilities (Queues, Topics and Subscriptions) then you can install Service Bus for Windows Server, which will allow you to test locally.
http://msdn.microsoft.com/en-us/library/windowsazure/jj193022(v=azure.10).aspx
For relayed messaging you will have to use an Azure account. The costs of using the relay service for development and testing are minimal, so it may be worth creating a pay-as-you-go subscription for this.
Unfortunately there is not an emulated Azure Service Bus you can run locally. The Azure Service Bus requires an active Azure Subscription. You will need a trial, MSDN subscription, or pay for a pay-as-you go subscription. The relay itself is extremely cheap - $0.01 per 10,000 messages. Dive in and start experimenting with your Azure 90 day trial. If you run out of trial, I'm sure MS would work with you if you could justify the extension.
One of the reasons I expect that it doesn't work without a subscription is that the service bus requires Azure ACS for authentication (this is the source of the Issuer Name and Key you are looking for) which also lacks emulation to my knowledge.
