Designs and manages multiple websites while ensuring data backup and disaster recovery

I have experience with AWS, and I am most familiar with the server environment, as we just use the server environment and then use Microsoft products on an AWS environment. I have experience with Windows Server IIS, which I ran on my own on-premise data center. The website was developed and then hosted, and through IIS, we managed the servers. The manageability within the IIS environment is not very difficult. For server management, you need to ensure data backup, data restore, and you have a DR configured to keep the database intact. It was done on-premises, so I had no problem doing that. If you have to go to the cloud, then you should have the storage connected to the IIS server and also have a DR set up for that. I didn't use Microsoft Azure tools, but since it is a Microsoft product, Azure has all the portability, so you don't have to worry about compatibility on the cloud. On a scale of 1-10, I would rate this solution a 10.
