Enable SQL Service Broker in SQL Azure
Service Broker should be available in Windows Azure.
Today we don’t have a cloud equivalent of SQL service broker outside of either service bus or SQL Server in a VM. I’d love to understand the scenarios that you have in mind. Please send me email at email@example.com if you’d like to continue the conversation.

Would like to see this added so that we could implement "Asynchronous Triggers". Without this, our options are:
1) Actual Triggers. But this isn't an option because this introduces unacceptable performance delays inside of our transactions.
2) A "poor man's queue in the database" with external asynchronous processes that poll tables in the database to determine if a message should be inferred. Because of the external nature and additional moving parts, this exponentially increases the delayed effect of this asynchronous trigger and greatly increases the complexity of the solution and maintenance/support efforts.

We use the service broker to feed real time data changes to our data warehouse w/o impacting the performance of the original SQL update.

We started to migrate some web apps from on-prem to azure, but we ran into the roadblock of Service Broker and SqlDependency not being supported. We need a means to call our .NET code when changes are made to specifiable data in a db. Either Service Broker and SqlDependency OR .NET Framework CLR integration with CLR Triggers OR some new and improved means.

Ok, an even 600 votes. Time to renew the plan for service broker!
The scenario that's interesting under this architecture is integration with the service bus and specifically eventhub. If service broker enables update message posting to eventhub then granular data transactions can be easily replicated to other systems.
I would love to see this feature to implement real time database change notifications.

I would love to see this to, its been a barrier for me to move certain systems to Azure. Without it, for me, it means re-architecting some complex systems, to make them even more complicated.

We've been using Azure SQL Database for a while now but unfortunately we will be changing to SQL 2016 VMs due to needing Service Broker type functionality to trigger updates to our other database systems.
What is the alternative of Service Broker in Azure to get notification on insert or update in db

I also need Service Broker, same reasons repeated multiple times here. Hopefully you guys will post a good news about this soon. Thank you.
I concur with the masses here. SQL without service broker does me no good. We have processes that are transactional, and processes that are not. For those processes that do not need to be execute in real time service broker manages in a very clean and robust way. It's like saying, hey do this immediately, and do the rest when you get to it.

Service broker, or rather that lack of it, is the one part of functionality that stops us moving to SQL as a Service. Any news on the review?

We use Service Broker in on-premise SQL Server to support caching and to provide asynchronous database change event notifications to web apps. Migration to Azure SQL Database service without SB is an obstacle. BTW, AWS RDS supports Service Broker.

1. Async Internal SQL Operations.
Our “Comms Input” Worker Roles are streaming results to the database. It is time sensitive, it needs very short & predictable write operations. Occasional a set of values will trigger an event which results in thousands of customers being affected. SQL now needs to update multiple tables to update their account balances. This can take a few minutes, but can’t delay the injection of the streaming input. Service Broker lets me decouple this work. It also changes the security context to keep these very sensitive finance table updates isolated from web users. (or any other user)
2. Existing Azure Queue alternatives are merely unintelligent queues.
Azure Storage Queue required you to poll it. This becomes expensive if you want latency < 100 ms. It burns CPU unnecessarily.
Azure Service Bus is better but requires an WCF app to process messages on arrival. You need to roll your own poison message handling & in-order queue delivery etc. It becomes hard to get multiple readers to “play nice”. If a Reader is shutdown it can take many seconds for any unprocessed messages to appear back on the queue so another reader can process them.
Service Broker is much simpler to write. Every message received is processed inexpensively with low latency. Meaning at night when I may only get a message every few minutes they are still processed as rapidly as in the middle of the day when we get thousands of messages(updates) a minute.

Selecting Service Broker to communicate between the facets of a system is a fundamental architectural decision; the system's operating environment is wholly constrained by the decision to use Service Broker. If SQL Azure does not support Service Broker then it cannot be used; Azure is precluded as a deployment option, unless SQL Server is installed on a VM. Clearly, this suggests SQL Azure-based applications can benefit by having Service Broker available in SQL Azure.
One scenario is to synchronize data between databases, one of which is a master identity database that holds the identities for the same persons in the separate systems. The number of potential scenarios is unlimited.

SQL Service broker and sql dependency allows our web applications to serve real time data to connected clients driven by changes at the database level. Without the service broken on Azure it is impossible for us to migrate our applications from traditional VM's without significant changes and re-development.

Using a Patient Queueing service using SQL Dependencies and company wants to move to an Azure set up and currently there does not seem to be any way to work around this.
Service Broker should be in Azure.

We use SQL dependency in an occasionally connected android application were part of a transaction is started on one tablet and completed on another. We use SQL dependency to tie these events together. Currently we use a RESTful web service to communicate to the backend but would really like to use Azure Mobile Data Services, but we need to keep the SQL dependency capability.
I have implemented Audit (Saving Old Value, New Value, User ID) on all of our tables using SQL Broker. Not only that i have event triggers run on this audit using SQL Broker which executes Stored Procedures. We are hold on moving to cloud because cloud does not have SSB Enabled.
Agree, service broker is great for simple and complex queue. E.g. I would like to open a sql connection and wait for messages to be received instead of polling every x seconds.
