how to schedule web jobs with day light saving. we have schedule web jobs on azure to run service(15:00 UTC and 8:00 MST) but when day light saving start it run 9 AM MST. could you please tell me, how to manage fix it.
If your app is hosted on Azure Virtual Machines, you have complete access to the VM so you can configure the time zone to whatever you want.
If your app is hosted on Azure Cloud Services, it is possible to write a startup script that calls the tzutil utility to change the time zone; however this isn’t recommended and can apparently lead to instability.
If your app is hosted as a Web App on the Azure App Service (formerly known as Azure Websites), until recently you were completely out of luck. However, there is now an easy and supported way to change the time zone for your w3wp process (and any processes it spawns):
All you need to do is add an Application Setting (via the portal or the management APIs) called WEBSITE_TIME_ZONE and set that to the name of the time zone as defined in the Windows Registry under HKLM\Software\Microsoft\Windows Nt\CurrentVersion\Time Zones\ (for example, “AUS Eastern Standard Time”).

We are migrating to Azure. We have a Web App deployed. However, I have a Windows Service that I need to add in to the mix. The service continuously runs, checking the associated Service Bus Queue for messages every 5 seconds.
I am looking for recommendations on how to do this.
I have looked at Web Jobs. But, I don't understand how it gets kicked off. I know there is a Web Hook involved - but I just want the code to run continuously without having to be constantly kicked.
We are also trying to avoid the cost of having a VM involved.
Thanks in advance.
Since you already have a web app, you could use a Azure App Service to run the Web App. The Azure App Service will allow you to also have a Web Job that you can have run on a schedule.
It does not make sense to break you web app into Azure Functions since it is already built. You can have the service run in an Azure Function, but it will probably add more complexity to interact with the web app (if that is what is happening) and if the service is running every 5 seconds, that could get costly.
I am new to Azure Cloud Service. I have created a Web Role in it.
Each time I want to do some updated in my Web Role application I have to create Package and upload it to Azure Cloud Service.
I have to do it for even a small design change (HTML Change).
Is there any better and fast way to upload cloud service/Web Role?
Thanks
The time to upload a package really depends on the internet speed at your disposal. With good speed, it usually takes a few seconds to upload MBs of a package. It is the deployment which takes time.
Azure Cloud Service, either Web Role or Worker Role, is a full Virtual Machine which gets instantiated when you deploy/re-deploy the package. The VM essentially takes the amount of time as a normal PC. There no workaround to lessen the time to launch of the VM.
we were able to schedule backups and monitor them for web apps hosted on Azure app service plan (Standard tier). we were also able to configure backups for function apps hosted on app service plans. but the backups are not happening as in web apps.
Could you please help on this. Is the feature supported with function apps. If not supported why are we able to configure backups for function apps also.
Update 1: Joy, thanks for confirmation.
providing you the error shown in log while backup, any clue for figuring it out
I think you could try again, I test it on my side, it works fine. Refer to my screenshots.
My azure function in a Standard service plan:
Backup configured, scheduled backup started on Thursday, July 12, 2018, 1:30:15 PM GMT+8. And it succeeded.
I scheduled a webjob to run daily at 2 am using cron expression (0 0 2 * * *) following tutorial from Create a scheduled WebJob using a CRON expression
and my server is created in "north central US" region, so i hope it should run in US central timezone but seems it running at different time than what i specified.
Based on the comments mentioned here, WebJobs run into the timezone configured for the WebApp where your WebJob is hosted. From this post:
Assuming you have not configured anything for the timezone, your cron job should use UTC which is the default timezone in Azure.
From Changing the server time zone on Azure Web Apps, you can specify the time zone you want your application to run in by making an application setting called WEBSITE_TIME_ZONE and set it to a proper value. From this blog post:

The default time zone is GMT as per the MS documentation

we had a strange issue a couple of times now with our Azure service.
We have a cloud service installed that has a web application running on it.
The service was created sometime around beginning of december and he first deployment was done that time as well. After that we did multiple deployments to the cloud service, but (it happens a couple of times now) sometime the Azure decides to roll back the deployment to initial one - the one that was made 2 months ago. This happened this midnight once again and we see that the files creation date on the "restored" or "rolled back" instance is 12/5/2013, which seems to be the date when we did an initial deployment.
A question:
1) Why does that happen?
2) How can we determine what caused this rollback?
3) How can we prevent the rollback?
or
4) How can we make a "snapshot" of the cloud service so when the Rollback happens, it actually rolls back to the latest stable image?
Thanks,
Denis
How are you doing "After that we did multiple deployments to the cloud service"? Are you doing this via WebDeploy or via RDP to the Azure VM?
PaaS cloud service VMs are stateless. The code that is running your website will frequently be rebuilt from the original .cspkg that was uploaded. See http://blogs.msdn.com/b/kwill/archive/2012/10/05/windows-azure-disk-partition-preservation.aspx for a bit more info.
If you want to make changes to your webrole then you need to upload a new cspkg. See http://msdn.microsoft.com/en-us/library/windowsazure/hh472157.aspx for more information.
If you are deploying via WebDeploy you should know that these changes are only intended for development/testing cycle and that the changes are only temporary. See http://msdn.microsoft.com/en-us/library/windowsazure/ff683672.aspx for more information, in particular the "For development and testing purposes only" section.
