Why WISP is better then Virtualized.

I am happy when I am not the only one with bad experience with virtual machines.

I like a lot stuff like Xen virtual machines but…sometimes they did not soleve problems, they generate them!

While I was looking for hosting, I heard a couple of recurring questions from users and potential hosting companies:

Why not go with Linode/AWS/[other virtualized hosting]?

My own experience with virtualized hosting is that I/O performance can be very poor, and that it can be impossible to diagnose underlying I/O problems from within the virtual machine. For example, in early days of Pinboard we found ourselves hosted on a machine that needed to recover a RAID volume. This so crippled I/O that it forced the site onto a backup server for three days, and yet from the perspective of the virtual machine everything looked the same. The ‘physical’ device was still mostly idle, just a hundred times slower than it used to be. That and similar adventures cured me of any desire to host on a non-dedicated server.

I have the exactly same problems. I changed from a semi virtualized hosting to a rocket Xen hosting. It was good, and I have a very good support. But I/O performacne was weak.

Mashape, Heroku, OpenShift and DotCloud are a good example of what a WISP must provide, even with some slight differences between them.

The bad things about this Service provider is they all use custom API to deliver similar result.

 

 

Why be difficult when, with a bit of effort, you could be impossible?
