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 ...

Managing Risk in IT

The IT debacle at RBS has highlighted the dependency large financial organisations (and other companies) have on their IT infrastructure.  From what has leaked out into the press, the RBS issue relates to a piece of software called CA-7, used for mainframe batch job scheduling. When I first started in IT in 1987, CA-7 (and it’s sister product CA-1, used for tape management) were already legacy technology.  From memory, I believe CA acquired the products from another company; both had archaic configuration processes and poor documentation.  However they did work and were reasonabl...

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...

APIs: Essential for Delivering Storage in Enterprise Cloud Infrastructures

It’s pretty easy to pick holes in the current legacy storage products, especially when it comes to integration within both public and private cloud deployments.  However it’s worth discussing exactly what is required when implementing cloud frameworks, as the way in which storage is deployed is radically different from the traditional model of storage operations.  In this post we will look at why traditional methods of storage management need to change and how that affects the way in which the hardware itself is used.  This leads to a discussion on APIs and how they are essential...
