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 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)

Go read that headline again: W. Curtis "Mr. Backup" Preston points out on his
blog that replication is not backup, and we can't disagree.
Keeping alternative copies of data in multiple locations is a great idea,
reducing the risk of data loss and potentially enabling enhanced access, but
it's not a historical data protection (aka, backup) strategy.
Backup requires management of multiple historic copies of a data set.
Clearly, cloud storage in itself isn't backup.

Protecting personal data, like backup and disaster recovery, can be hard to
get people excited about. Although we see the problem plainly and solutions
are widely available, it can be hard to convince business management that
technologies like encryption are worth the investment. But new regulations
promise to change all that: Massachusetts and Nevada have enacted data
protection laws that require encryption of personal information in transit.
It's about time, too. Data losses have been all over the news for a decade,
and everyone in IT knows that much of the data crossing network... (more)
In my last blog post, I pointed out the new laws in Massachusetts and Nevada
that require all personal data in transit to be encrypted. That post
generated lots of discussion, including thoughtful responses from Steve
Duplessie and Joseph Martins, and I urge you to read those as well.
Two key questions remain: What exactly do these laws demand and how will you
actually comply with them? Sure, encryption technology is widely available,
but actually implementing it has been a slow uphill climb for most IT
organizations. Let's examine the implications!
