Flexible with high performance and good reliability
The solution scales well. As an example, there has been an American telecom service provider that had 20 million users, and the data of those user profiles had been stored on Dirx Directory, and they don't have any issues in retrieving the data and using it for any kind of services. Regarding our clients, the amount of users depends on if you have end users that don't really use this Directory or not. They are stored in this Directory and make use of the services that are administered via this Directory. There we are talking about millions. Then, you have administrators who configure the Directory and there we're talking about, let's say, hundreds of users.

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.
