@Karthikeyan Annadurai , Adding to what Alan Kinane highlighted. Azure WebJob will not be affected.
We're also working on adding an FAQ in the doc to add more clarity on this.
****Q**: What will happen to my scheduled Azure Web Jobs from Azure Scheduler?**
A: Web Jobs using this way of Scheduling Web Jobs are not using the Azure Scheduler internally. For the schedule to work it requires the website to be configured as 'Always On' and is not an Azure Scheduler but an internal implementation of a scheduler.
--The only type of Web Jobs that would be affected are those that are specifically using Azure Scheduler to run the Web Job by means of the Web Jobs API. You can trigger these WebJobs from a Logic App using the HTTP Action.
Thanks again for your feedback!
