 I'm Randall Sobi, I'm an Institute of Particle Physics Research Scientist at the University of Victoria and I'm involved in international collaborations such as the Atlas Experiment which is studying high energy proton-proton collisions at the Large Hadron Collider at the CERN Laboratory in Geneva. It's a basic research physics project that's trying to just understand what the universe is made of, its constituents, and just what we're made of. Well these projects such as Atlas record a lot of data, typically we have 200 of these proton-proton collisions we record at 2 megabytes each, so we're recording 400 megabits per second. So this adds up to a very large data sample. So we have computing facilities that are geared to managing this data around the world. We have in the past used the grid technologies, but now we're moving to cloud technologies which OpenStack is a key element of it. So many of the facilities that we use around the world, I mean being an international collaboration, each country or group of people bring their computing facilities and contribute them. So one of our goals is to utilize these distributed computing cloud facilities in an integrated way so all our users around the world can use them for their data analysis, leading to projects like the discovery of the Higgs boson. Cloud technology is still sort of at the beginning for us, we're just starting to learn how to use it in our distributed model, but it looks like it has a lot of potential for simplifying the way we do our computing and maybe making our resources more efficient and more effective for our use. To say we're sort of at the beginning and we're learning how to use them in our current infrastructure. We're trying to bring in the technologies gradually into our production systems, so we have a combination of research projects on the computing end of with OpenStack clouds, but in some places we're just starting to bring them into the production systems. The grid sort of had a lot of promise, but in the end we started to just write our own things and we got kind of isolated in the way from all the development that the commercial world is doing. I think now the cloud, we see that the big users are making a lot of developments and technology that we can use and I think OpenStack is attracting. We can see today all the big companies and so we're trying to figure out ways in which we can leverage their developments for our needs. Having users I think is always a good way to get feedback on the development. I think also the developers like it when people use it. You don't want to build it and they won't come. So now our experience with OpenStack is quite positive.
