问题
I have one SQL Agent maintenance job which checks the index fragmentation within a database and rebuilds indexes if required.
This is running well in my test server (Microsoft Sql Server 2012). But my production server is in Azure. Now I want to schedule that job to Azure.
SQL Agent does not exist in Azure SQL database so how can I schedule a Sql Job in Azure Db?

Since this question was first asked, there is now another alternative to handle this problem:
Azure Functions
Here are a couple of examples that could easily be modified to call a stored procedure that rebuilds your indexes
- Create a function in Azure that is triggered by a timer
- Use Azure Functions to connect to an Azure SQL Database
Also see
- How to maintain Azure SQL Indexes and Statistics - this page has an example stored procedure for rebuilding your indexes that you can download.
- Reorganize and Rebuild Indexes
A few things to keep in mind with Azure functions
- They are built on top of Azure Web Jobs SDK and offer additional functionality
- There are two different pricing models:
- App Service plan (attach it to an existing plan)
- Predictable cost model
- It puts extra load on the same VM used by your web site
- Consumption plan
- You get some free processing every month
- The default maximum run time is 5 minutes to prevent billing problems, but it can be changed via the host.json file.
- App Service plan (attach it to an existing plan)

This feature has been rejected by Microsoft, see here.
To quote the post:
Today in Azure there are several alternatives,
1) SQL Database Elastic Jobs http://azure.microsoft.com/en-us/documentation/articles/sql-database-elastic-jobs-overview/
2) The Azure job scheduler http://www.windowsazure.com/en-us/services/scheduler/
3) The new preview of Azure Automation http://azure.microsoft.com/en-us/services/automation/.
4) SQL Server in a VM
Option 1 requires an additional dedicated cloud service, which increases cost. Option 2 is free (I think) as long as you don't run more than once per hour.

Azure SQL does not support sql jobs. From documentation:
Microsoft Azure SQL Database does not support SQL Server Agent or jobs. You can, however, run SQL Server Agent on your on-premise SQL Server and connect to Microsoft Azure SQL Database.
WebJobs: If you have a website you can create webjob and run it on schedule. See more here

You can use Azure automation to schedule jobs on an Azure-DB like the on premise SQL Agent.
See https://azure.microsoft.com/nl-nl/blog/azure-automation-your-sql-agent-in-the-cloud/ for more information.

Another option is rovergo, a service that allows you to schedule sql jobs with a cron expression. This is nice because you don't have to create a web job or azure function. You can simply schedule a sql script.
(I'm a developer on rovergo)
