At the end of August 2012, Amazon Web Services released their latest service
offering – a long-term archive service called Glacier. As a complement to
their existing active data access service S3, Glacier provides long term
storage for “cold” data – information that has to be retained for a
long time but doesn’t require frequent access.
What Exactly is Glacier?
Many organisations need to retain data in archive format for extended periods
of time. This is for regulatory or compliance purposes or may simply be
part of their normal business process. Good examples are medical,
healthcare, financial or media (video and audio) data. Typically for many
IT departments, backup has provided a lazy way of archiving information.
Access to backups retained for up to 10 years provides a cheap and
rudimentary archive service. However backup isn’t archive (see my recent
Before IP Expo this year, I was invited to a Q&A session with Zane Adam,
Microsoft General Manager for Azure. I’ve not posted any video from
the event (yet). Fortunately Microsoft have saved me the effort and posted
a few clips online. Here’s one video with a few interesting questions.

It’s hard to believe that over three years ago I asked a question on where
hybrid drive technology had reached. I was thinking of the Enterprise
market at the time and as far as I am aware, at this stage, no Enterprise
storage array manufacturers have yet integrated these devices into their
products. At the consumer level, of course there are products out there,
most well known being Seagate’s Momentus XT drive. But there is another
approach to speeding up the hard drive and that’s to use SSD as a cache but
in a slightly different manner. A good example of this is the OCZ Syn... (more)
One of the benefits of delivering Infrastructure as a Service (IaaS) through
the cloud is an abstraction from the underlying hardware delivering the
service. There’s no requirement to understand what technology is being
used to deliver, for example, cloud servers. The specification of a
cloud-based server is based on a few simple metrics, CPU, memory and disk
CPU or processor power is described by most vendors in terms of cores, which
translate to some abstract definition of physical computing power. Only
Amazon Web Services (AWS) reference physical CPU architecture, w... (more)
Today is the official launch of the Raspberry Pi, an ambitious UK project to
create low cost computing with the aim of bringing a proper understanding of
computing back to education. The device is itself is a fully fledged
computer the size of a credit card with external USB and HDMI connectors.
What’s remarkable about Raspberry Pi is the price; there are two versions,
Model A and Model B (echoing the BBC Micro options from 30 years before),
selling at a target price of $25 and $35 respectively. The extra $10 for
the model B gets you a fixed Ethernet connection and an addition... (more)
