It’s been an exciting couple months at LeanServer! We’ve grown, completed several high profile betas, and released a new product.
Our newly released product is the Reliable Transfer Client – a cross-browser plugin that brings a premium upload experience to any ASP.NET application. The client addresses the many client-side issues with uploads, especially for really large files, including things like:
- Support for very large file uploads from any browser (5Gb, 10Gb, 20Gb, etc)
- Fault-tolerance to connectivity and server errors during upload
- Ability to resume uploads at a later time
We originally developed the client for a number of high profile media sites that wanted to have complete control of the upload look and feel, so we made it completely transparent and driven by javascript. You can see more here:

We’ve also recently done a few videos to showcase the performance and scalability features of the ScaleUP platform, which you can see here:

20X Faster Web Uploads
With LeanServer ScaleUP

Very Large File Uploads With LeanServer ScaleUP
With the Reliable Transfer Client in the browser and ScaleUP on the server, we are able to turn any ASP.NET application into an upload powerhouse.
Uploads definitely pose a number of interesting scalability problems, which have been fun to work on. We are
shortly releasing an enterprise storage pack for ScaleUP, which provides advanced storage and processing features that high traffic environments can use to process and distribute uploads efficiently.
We’ve also been making great progress with several other performance technologies, which should become available for beta shortly. Stay tuned!
