Use Cloud File Server to Solve Slow Uplink Problem

When office internet speeds are limited, it's difficult for employees who work from home to connect to the office network via VPN and access files simultaneously. The solution is to set up a hybrid environment of a cloud file server and an on-premises file server so that employees in the office can still access files locally and remote employees can access files from the cloud.

A story about the slow uplink problem in the office

There is a design and architecture firm in a city where the only Internet service provider offers upload speeds of only 50 megabits per second (Mbps). Users are connected to a file server of about 5 - 10 TB to access files in the office. However, with the mobilization of the workforce and the proliferation of the work-from-home model, employees who worked from home found it difficult to access their files, resulting in lost productivity. With more remote users connecting to office facilities, companies like this were struggling with bandwidth capacity issues. The much heavier load was straining the connections of the company's infrastructure. Employees working remotely either did not have access to the Internet, or their connections were so poor that they hurt productivity. Internet speed in the office became a bottleneck, causing users to struggle with latency when accessing files remotely.

strategies of move to cloud

Move to the cloud

Since the local ISP could not solve the slow uplink problem without a significant infrastructure upgrade, the company considered moving the file server to the cloud. There are two different strategies for this. The first is "lift-and-shift", the second is the combination of cloud file server and local file server.

Lift-and-shift is easier if the Internet in the office is fast, so a site-to-site VPN between the office firewall and the cloud virtual network acts like part of the local network.

The hybrid cloud file server is a good balance between the local file server and the cloud file server, so employees in the local office can still use the file server over a local network.

Why not migrate to SharePoint?

When it comes to migrating a file server to the cloud, why not SharePoint?

Suppose the file server's data set is more than one TB, with unique custom applications, databases, Adobe, AutoCAD, Mac users, or other factors mentioned above. In this case, the IT team may not want to try SharePoint for the following reasons.

Are you familiar with these SharePoint Online limitations?

  • 5,000 item - When you have a large number of items in a document library, the performance degrades to the point that it becomes unusable.
  • 300,000 item - This limits the number of documents users can sync using the OneDrive sync client. Performance starts to degrade.
  • 400 Character URL Limit - The URL path for all files and folders must be 400 characters or less (and no more than 400 characters for any single file or folder name in the URL).

Empowers Windows File Servers with Cloud Remote Access

Hybrid Cloud File Server to Solve Slow Uplink Problem

Businesses in rural areas with slow upload bandwidths have no choice but to find an alternative way to keep their employees productive as the population shifts to the work-from-home model. They also want to provide a local copy of sensitive data if Internet access fails for security and ownership reasons. They found a solution that allowed them to migrate their on-premises data to Azure and bypass connectivity issues for employees. They wanted bulletproof security to prevent employees from downloading or copying sensitive data to their personal computers or devices.

offline editing

Offline Editing

The default method for accessing file servers in Azure/AWS is to use a VPN agent. However, VPN requires an active connection to the file servers and does not support offline edit mode. Therefore, Internet interruptions can disrupt a user's typical workflow.

Big Folder Browsing

Big Folder Browsing

A great way to use Azure/Aws file servers is to map a drive to the file server over a VPN. The frequent exchange of request and response messages between the local drive and the remote server, without local caching, makes it difficult to browse large folders.

Large File Transfer

Large File Transfer

Working with large files is not easy, even with a VPN agent connecting to the file server in the cloud. Applications like Photoshop or AutoCAD usually generate large files and use many linked files. These applications suffer from a slow VPN.
