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, with
processing assigned EC2 Compute Units (ECUs). You can find more details
here, but summarizing, an ECU is approximately the power of a 1.2Ghz 2007
Intel Xeon Processor. Memory is a more tangible quantity and simply
expressed in megabytes or Gigabytes. Storage references purely disk

This week has seen announcements from two companies I’ve been interested in
and following for some time.
Nasuni makes a storage appliance that stores all of a customer’s data in
“the cloud”. It’s available either as a physical device (effectively
a server running their software) or as a virtual machine. What makes their
product interesting is that both the data and filer configuration reside on
the cloud and can be reconstituted anywhere if for some reason the filer is
lost (for example if the appliance is down or power was lost). The only
piece of data the customer ne... (more)
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,
This is one of a series of posts discussing the new features in Windows

This post reviews the new Hyper-V 3.0 feature, Virtual Fibre Channel.
Virtual Fibre Channel (VFC) enables a Hyper-V guest to access the physical
storage HBAs (host bus adaptors) installed in the Hyper-V server. Normally,
storage adaptors would be reserved for the use of the Hyper-V guest itself
however this new feature acts as a passthrough, enabl... (more)
