This session examines the second wave of the virtualisation tsunami to hit the shores of the data centre: that of network and application infrastructure. It looks at the architectural implications of Application Delivery Controller virtualisation in the data centre with a view to maintaining appropriate levels of reliability and scalability.

  • When users are all over the world, globally distributed access across several datacenters can help solve access and availability requirements, but both the userbase and IT administrators still need a solution that is easy to use and simple tomanage. At the same time, the worldwide strain on budgets is forcing customersto reduce the number of data centers while still offering fast and secure applicationperformance to the global user base. Content delivery networks (CDNs) can placecertain objects at the edge of the network for fast access, but the cost of entry forusing a traditional CDN can be prohibitive for small-to-medium-size businesses.There are also security and control concerns with traditional CDNs because somecontent is shared, which can be perceived as a potential risk to the business.
