Google, Yahoo, Youtube, Hyves and Nu.nl, they all share one thing; a huge number of visitors who expect nothing more than an always working and responsive site. IC&S is specialised in internet platforms and all the challenges that come with the territory. In our lecture we will tell you about the technologies that are needed to keep these sites working. When doing more then 200 million hits a day it's no longer about computer power but rather the design of infrastructures that allow such traffic. We will share some of the insights about large and high performance storage platforms (like Google FileSystem), Thundering hurd problems and livelock situations. New buzzwords are popping up faster than companies are able to implement them. Web 2.0 will bring and is bringing lots of extra interactive features to web applications, but has it's toll on the platform side. We will show you some of the new technologies (like XML firewalls) to handle the load of these new internet features now and in the future. As a lot of these subjects will be explained in much detail, a (mostly) beta background (i.e. computer science, maths, physics, CKI, etc) is preferable.
