It caught my eye the other day that Microsoft announced an equivalent to Amazon Web Services’ Direct Connect offering, i.e. the ability to connect from your premises to your cloud deployment without going over the Internet. The press release says this capability is “expected to be available in first half of 2014” – and I assume that this initial launch will be US only with Europe to follow later, although it doesn’t say.
Smart421 was a Direct Connect launch partner in the European region for AWS back in Jan 2012, although the initial US launch was way back in August 2011. So going on that basis, I can now put a crude estimate on how far behind AWS the Azure platform really is – at least two and a half years
Anyway, now is as good a time as any to share some brief stats from our real world experience of deploying Direct Connect for the European region. I’m not aware of much data in the public domain about Direct Connect latency measurements in the European region – so if you know of some, please comment on this post to let me know.
On a 1 gigabit connection, for an ICMP (i.e. ping) round trip we typically see a latency of circa 12-13ms for Direct Connect versus 33ms via a VPN over the Internet, i.e. about a 60% reduction in latency.
This data needs to be considered carefully as there are a multitude of factors at play here depending on the specific customer environment and requirements – such as the Internet connectivity for the VPN, and crucially where the customer “on-premises” equipment is in network terms with respect to the AWS Direct Connect location in London Docklands. Also any comparison will vary depending on time of day etc. I’m deliberately not providing any stats on achieved bandwidth here as there are just too many factors involved – principally that the limiting factor is likely to be any MPLS connectivity involved in the architecture rather than Direct Connect itself.
Still – it’s interesting data nonetheless…thanks to ‘Smartie’ Wayne for compiling the data.
