Platform as a Service is variously defined, but it generally refers to a middle layer between infrastructure (hardware and software) and applications. Cloud platforms offer simplified interfaces for a new generation of applications that use web protocols and are often coded in language...
CNET's Gordon Haff wrote a great piece on the shortcomings of the exchange model for cloud computing. His prognosis is right there in his title: "Why cloud exchanges won't work." I've done some thinking and writing on the topic, and it's easy to see Haff's...
Since cloud storage is not backup in and of itself, anyone wanting to use cloud for backup needs additional software smarts. One of the smartest data protection and archiving suites out there is CommVault's Simpana. Mixing their intelligent software with the benefits of cloud stora...
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 enha...
I'm loathe to give predictions, preferring introspection and outright silliness. But the turn of the year is a time of optimism, so I will take my turn at the megaphone to dish out some ideas I believe will come to pass in the coming year. 2010 will be a year of normalization (“rightin...
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...
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:...
Take a look at the various data storage offerings called "cloud" and your head will start to ache. How can so many things all bear the "cloud storage" name and yet be so totally different? The answer is obvious to long-time industry observers: Each provider has tail...
Although the capacity of storage systems keeps growing, data growth keeps absorbing available capacity. In an effort to contain costs, IT organizations turned to tiered storage but have encountered a "glass floor": Disk space is a small component of costs, reducing the impact...
Storage capacity keeps growing, but unstructured data grows at least as fast. IT organizations have tried to contain costs, but tiered storage has not worked out that well. Although there are technical limits to the effectiveness of tiered storage, the biggest challenge is a business o...
The growth of storage capacity led to an attitude that storage was too cheap to manage, but this didn't last long. Before we knew it, IT was faced with a flood of data, easily too much to manage. Faced with limits to their ability to control data growth, IT tried to get the business in...
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: Difficult...
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 d...
In his latest blog post, Michael Hay of Hitachi Data Systems points out that expensive tiers of storage ought to be reserved for business data that generates positive cash flow. By extension, he suggests, non cash-generating applications should be restricted to lower tiers of storage. ...
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 ...
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 n...
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. ...
Many in the IT industry seem to enjoy arguing exactly what does and does not constitute a cloud service. As I mentioned in my post on the controversy over private cloud services, I do not feel that these arguments are productive. We should focus on results and business value instead of...
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 co...
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 s...
As discussed last week, cloud storage solutions differ in many ways. They can be defined by their pricing model (usage-based or capitalized), their location (on-site or off-site), the granularity of scalability (per-file, standard unit, or per-system), and whether or not they are multi...
Especially intriguing is George's assertion that existing backup systems are antiquated and out of touch with the times. Similar statements were made by the continuous data protection (CDP) pioneers a half-decade ago. And the latest disk-to-disk backup trend certainly demonstrates that...
IT is great at some things, but out of its league in many cases. Business continuity planning is an example of the latter: No matter how well we set up our applications and systems, the human element is always a roadblock. Sure, we can build a complex system to return our CRM system to...
This description does not strike me as all that useful, so I put this simple question to a number of folks on Twitter and through direct discussion. I contacted W. Curtis Preston, "Mr. Backup", for his opinion. He pointed out that just about any copy of data can be used as a backup,...
The Enterprise Strategy Group forecasts that the enterprise NAS market will continue to grow like gangbusters over the next two years, reaching 62,000 petabytes in 2012! That number represents a huge sales opportunity for EMC, NetApp, Dell, HP, IBM, BlueArc, and the rest of the traditi...
