Architecture
Nimbus.io uses parity striping to spread data across many servers redundantly - providing bulk storage with equal reliability and less than half the overhead of replication based storage systems.

Documentation
The API is similar to S3 or Rackspace Cloud Files - favoring JSON over XML. For easy portability, we supply libraries to use Nimbus.io as drop-in alternatives for the most popular libraries to access competing cloud storage platforms.

The server and client components are all free and open source software. The server software is made available under the AGPL license. Clients libraries are available under LGPL.

Pricing
$6 per 100GB of purchased storage. Transfer in is always free. Transfer out is $0.06/GB. PUT and LISTMATCH requests are $0.01 per 1000. Other requests are $0.01 per 10,000 or free.

Varnish is an amazing and incredibly efficient tool for serving up common resources from your site to end-users. Besides simply making your site faster, it also can add additional redundancy to your setup by acting as a full backup if the web servers fail. In order to make Varnish both serve as an effective backup and efficient caching layer, it needs to clean up incoming headers from the browser, strip down cookies, and consolidate the "Accept-Encoding" header.
After such extensive explanations it's easy to get overwhelmed, but the good news is that the VCL file provided here can quickly be deployed to almost any Drupal site and start working immediately. For most sites no further customization is needed, and sites that need to tweak it will have a good head start towards huge reductions in server load. On our sites, Varnish is usually able to handle about 85% of the traffic without ever touching the web servers. Even during peak times with hundreds of thousands of requests coming in per hour, Varnish can hum along at less than 5% CPU usage of an average 4-core server. Instead of scaling out your web servers horizontally, adding a few Varnish machines in front of them can save a huge amount of processing and speed up your site at the same time.
If you haven't already, grab the actual default.vcl file that we use on our sites and read it through start to finish. Now with all of the individual pieces explained in-depth above, we hope you can use it as a starting point for your own VCL configuration. Happy caching!
