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 art...

Microsoft Q&A Session: IP Expo 2010

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.

Alternative to Hybrid Drives – OCZ Synapse SSD

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...

Is the Performance of All Cloud Servers the Same?

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 space. 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...

Raspberry Pi Launch Aims to Herald New Era of Education in Computing

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...
