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 cloud storage.
Although there are cases where spot pricing might make sense, the nature of
data storage trends against this sort of pricing model. Let's explore the
Cloud compute is obviously different from cloud storage: The former deals

The current economic climate is pushing many to look for current-year budget
savings. This is one of the major reasons that cloud computing in general,
and cloud storage specifically, has become so attractive. Moving data into
the cloud doesn't just get it out of the data center, it converts a capital
expense (storage equipment) into an operational one (monthly fees).
But cloud storage isn't right for every application: One must profile
applications and consider where cloud storage or computing services makes

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 ... (more)
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)
The application of Moore's Law may have led to incredible advances in
computing, but the growth of storage capacity is even more impressive. Disk
and tape storage density has grown by a factor of 10 every five years,
driving out cost and bulk. $250 bought an amazing 20 GB of hard disk space in
1999, but this is nothing compared to the 2 TB that can be had for the same
money today. Yet enterprise storage costs have not dropped. The real cost of
an enterprise storage array has not fallen significantly in that same period.
In fact, the total cost of maintaining storage has actually ... (more)
