It would be rather stupid if any significant site went live (during production) on the CTP of the product ( edit - ) in the comments - this is not difficult. there are exceptions like stackoverflow). Velocity is currently in CTP2, which is good for developing proof of concept and product planning, but thatβs all. Once it is supported, I am sure we will see a lot of use. Follow the Velocity product group block ( http://blogs.msdn.com/velocity/ ) for details.
As for memcached vs Velocity, they have somewhat overlapping, but ultimately different goals. Memcached is not reliable. This is clearly stated in the documentation and the authors. It should be incredibly fast, cheap and easy to manage. Velocity, on the other hand, is much more familiar with the formal corporate platform. It is complex, with a robust API, and is better suited for a more formal data environment.
