Much discussion in the cloud computing world has focused on a simple
question: Is a private cloud infrastructure worthy of the name? It's been
posed in many ways, with some going so far as claiming that there is no such
thing as a private cloud. Although discussions like these are all too common
in many areas, the question really amounts to little more than counting
angels dancing on pin heads. The key issue is whether private cloud-style
infrastructure can deliver real benefits like public clouds can.
First, let's set out some definitions:
The draft NIST definition, perhaps the best we have at this point, states
that "Cloud computing is a pay-per-use model for enabling available,
convenient, on-demand network access to a shared pool of configurable
computing resources (e.g., networks, servers, storage, applications,
services) that can be rapidly provisioned and rel... (more)
As I discussed in my previous post, What Makes Cloud Storage Different from
Traditional SAN and NAS?, today's cloud storage is unique from the SAN and
NAS (and even CAS) that has gone before. Beyond the cost and flexibility
benefits inherent in public cloud computing resources of all sorts, cloud
storage is unique in its openness, programmability, and the possibilities it
opens for distribution and collaboration.
These compelling benefits, along with an explosion of cloud hype, have led
every company with a product even remotely "cloudy" to jump into the market.

As discussed yesterday, the incredible growth of storage capacity led to an
attitude that storage was too cheap to manage. Excess data capacity seemed
always to absorb any new demand. But the unchecked growth of data led to the
serious issues that storage managers face today: Difficulties in protecting
massive data sets, concerns about compliance and litigation, and storage
budgets that refuse to shrink.

As we plummet down into Gartner's "trough of disillusionment", the cloud
skeptics are making their voices heard. Although my professional focus is at
the forefront of the cloud storage wave, I can not disagree with the content
of articles with sensational headlines like "Cloud Storage: It's Strictly For
Airheads" and "Why Cloud Storage Use Could Be Limited in Enterprises". The
authors are doing exactly what everyone should be doing: Questioning the
viability and suitability of cloud storage in the enterprise.
The truth is, although I'm not the "cloud police", not all managed stora... (more)
Early Bird Savings at Cloud Expo
This week, Amazon took a step with EC2 that many had long anticipated: They
announced spot pricing for cloud compute instances. EC2 customers can now
name their own price, and Amazon will bring compute instances up at variable
discount prices according to these "bids". This complements their March 2009
move at the other end of the spectrum, extra-cost reserved instances. This
evolution of the cloud compute market was predicted by many, but Amazon
deserves credit for making it happen.
The obvious next question is whether spot pricing can work for c... (more)
