From March 2015 Microsoft will host New Zealand and Australian business customers from Azure datacentres in Sydney and Melbourne. Microsoft’s new Australian Azure datacentres opened in October and will cater for Office 365 and Dynamics CRM Online customers.
For most New Zealand customers the move has two implications.
First, Australia is closer to New Zealand than the previous datacentre hosting Microsoft online customers.
Better than Singapore
At the moment a datacentre in Singapore hosts Microsoft’s New Zealand customers. Direct data traffic between New Zealand and Singapore typically has a ping time of around 120ms. Things are worse over the public internet where NZ-Singapore connections can even travel via the US.
Australia is 24ms from Auckland. To put this in context, that roughly the same as the ping times between the Auckland and the most distant mainland destinations in New Zealand.
Conventional wisdom says latency becomes an issue when ping times go over 50ms.
Latency an issue, but not that much
In general lower latency means you access applications faster and speed up data storage. In the case of Microsoft’s Office 365 apps, that might not always be noticeable as they handle most processing tasks locally on your machine. It will make a difference when saving or retrieving data from OneDrive storage.
Yesterday Kordia announced a Microsoft Azure ExpressRoute service. This gives New Zealand companies a private connection to the Azure datacentres. It bypasses the public internet and makes it possible to build hybrid clouds using on-premise servers and Microsoft’s remote services.
The second point about Microsoft moving its Azure datacentres closer to home is a tricky one: data sovereignty, security and confidence. When Microsoft hosts your data on Australian soil, it is subject to Australian law.
In a media statement Microsoft New Zealand’s managing director, Paul Muckleston, says Australian data centres help address data residency considerations, particularly in sectors such as healthcare, education, government and financial services.
Mucklestone is right in the sense that New Zealand organisations are more at home dealing with Australian rules than, say, those in Singapore. But Microsoft is an American company, which means it also has to operate under US law. If the US government decides looking at your data is a matter of its national security, then Microsoft is only going to resist so far.
The good news is that, to date, Microsoft has a good track record on resisting. However, if data sovereignty is a big deal for you or for your customers, you may want to look elsewhere for cloud services.
New Zealand government seems relaxed about hosting non-critical data in Australia. Some ruling National Party ministers and MPs have suggested moving most data offshore as a cost-cutting measure. That could yet backfire politically, but outside of specialist circles data sovereignty doesn’t seem to excite much interest.
For my money one of the best messages in Microsoft’s announcement is that the company will offer what Mucklstone calls “geo-redundant back-up”. What that means in practice is that should the Sydney datacentre run into problems, Microsoft will switch everything to Melbourne.
Although this kind of redundancy is exactly what cloud service providers would like you to think is standard practice, it would normally cost extra.
