 KloudBuster is a tool that can load the data or storage plane of any OpenStack
 cloud at massive scale and can measure how well the cloud behaves under load.

 * Requires Neutron networking (does not support Nova networking)
 * Only supports HTTP and storage traffic in this version
 
+Unlike some other scaling test frameworks, KloudBuster does *not* attempt to:
+
+* provide a scale test framework that works across different cloud technologies
+  (OpenStack + AWS + Google Cloud + ...) - we are only focusing on OpenStack
+
+* provide a scale test framework that is flexible and programmable to do everything - 
+  we just focus on opinionated and well targeted performance and scale areas
+  with sensible use cases and available in a fully integrated and easy to consume
+  packaged format
+
+* replace bare metal and domain specific native performance and scale frameworks 
+  (line level traffic generators, ceph specific performance and scale tools...)
