I am managing the S3 storage solution from Amazon. From Microsoft, I'm managing the Azure administration. I handle that. As a part of that, I need to create the virtual machines, a point to site to VPN and Azure AD, AD synchronization with Windows server, a database server, mail server, and web server. I administrate all that.
We use Amazon S3 for storing files and documents on the cloud. I fill out the user whenever the files they use are downloaded. That is fully automated. After a few days, it can delete it. I've done the policy for the automated deletion.
Amazon S3 is great. We are using it for storage solutions.
