Cloud Distribution Forecast: Unsettled

December 20, 2011

The issue of network latency and loss – and how we meet the challenge of developing cloud-ready applications on best-effort networks –  is a topic that has gained a bit more exposure recently with the Alcatel and Cisco announcements, coinciding with a paper from Joe Weinman.

In addition to the demands of realtime cloud applications, another reason that the network is returning to the foreground of discussion is IPv4 exhaustion. I’ve spent a fair amount of time looking at this particular issue in 2011, including the likely impact,  in terms of costs and performance, of the various duct-tape IPv6 transition methods that are going to be implemented globally.  Here is a copy of the slides from my presentation’ at Cloudcamp London (5th October 2011).

Synopsis:

The internet has become our defacto distribution network for utility computing (otherwise known as cloud computing). The global response to IPv4 exhaustion has, unsurprisingly, not been timely adoption of IPv6; as such we now face an immediate future internet where the incumbent players dictate the terms and conditions for entry. This is likely to have a negative impact on innovation in systems that are built on cloud.
