This morning I signed up and had a play with Microsoft Labs’ social media application, so.cl.  This was quietly released over the weekend with little attention as it’s a piece of experiment work rather than a new social media platform.  It’s early days to be commenting on whether so.cl will be useful; currently it appears to be targeted at students and search sharing.  I wonder whether the intention is to use the output to help improve the quality of Microsoft’s search engine, Bing. Anyhow, the so.cl interface is reminiscent of Google+ (especially party invitations, that seem to be like Google+ Hangouts) and that got me thinking back over some Twitter conversations relating to G+ over the last few weeks.  Those of you who use G+ on the iPhone will have noticed that absolutely awful recent upgrade, which somehow attempts to merge G+ information with the images peopl...

Storage in Cloud Is Not the Center of the Universe

In a previous post, I touched on the need to have APIs for managing storage in cloud environments.  In this post, I’ll talk about how the way in which storage is deployed in cloud environments has to change. For the last 10 years, the advent of Storage Area Networks (SANs) has created a storage-centric view of the world with storage at the centre and the “planets” – networking and servers – wrapped around it like some pre-Copernican view of the universe.  Over time, SANs have evolved to be ever bigger, with some organisations deploying huge fibre channel fabrics.  As we’ve seen ...

Amazon Delivers Cloud Archive Storage with Glacier

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, h...

The Evolution of Solid State Arrays

In the first wave of solid-state storage arrays, we saw commodity style SSDs (solid state drives) being added to traditional storage arrays. This solution provided an incremental benefit in performance over spinning hard drives, however the back-end technology in these arrays was developed up to 20 years ago and was purely focused around driving performance out of the slowest part of the infrastructure – the hard drive.  Of course SSDs are an order of magnitude faster than HDDs so you can pretty much guarantee SSDs in traditional arrays results in underused resources, but is prem...
