Lambda functions can plays an important role with backups and daily tasks. We can schedule the Lambda functions to do repetitive tasks, such as checking for idle resources, creating backups, generating daily reports ,and various other routine jobs. The old school involved installing a task manager application that was running on the server all the time and performing the task when required. But with Lambda, functions are invoked only at a certain event or schedule. They also scale horizontally when required and also it costs less.
