Story 1 - Accessing PhotoShop over VPN is slow
A marketing firm has many files on an on-premises file server that includes graphics files, such as Adobe Photoshop files. Due to the COVID-19 pandemic, the IT director wants to enable remote access to these files for employees working from home and remote locations. The company allowed a VPN connection which typically runs over the Internet, but the Internet has quite different network characteristics than a company or home network. Local networks usually offer a high amount of download bandwidth, low and stable latency, very little packet loss, and almost no data corruption. Contrary to that, Internet connections offer a lot less bandwidth and have a relatively high, very fluctuating latency, and data corruption is a norm.
Employees accessing the files over VPN connections started to complain about very slow directory browsing (because of significant latency). Copying a remote location file was very slow and opening files on home or remote computers was slower. Company A considered 100% cloud-based solutions to circumvent this issue but decided against it due to the large amount of data on the file server and the lengthy migration time to the cloud. Recreating folder permissions after the migration was also a significant concern for this company as pure cloud solutions do not keep the folder permissions intact.
