The 2008 market crash left IT leaders with far too much IT infrastructure that was misplaced and misallocated to the needs of their customers. See the attached charts of CAPEX. Five years on from 2008 we are in a period of recomposition for the IT industry — especially the network. I suspect that 2014 through 2020 are going to big years in which nearly all the networks on global basis are going to be rebuilt. 2013 is the year in which IT leaders are working through the process of figuring out what the pieces of the new network will look like. Once those technology choices are made, we will be off and running. — The Bigger Picture – Beyond Incrementalism | SIWDT
Thing is, while OpenNebula has traditionally been seen as a European, more mature counterpart to the AWS-aping likes of OpenStack, CloudStack and Eucalyptus, these days it’s pitching itself more to enterprise users as an open-source alternative to vCloud that comes with lower costs and support for multiple hypervisors. Llorente said that, while most of the OpenNebula community is using KVM or Xen (drivers for which are also improved in the new version, incidentally), 70 percent of customers are using OpenNebula on VMware.
According to Llorente, this means the OpenNebula and OpenStack/CloudStack cloud models can happily coexist – and for evidence of this, he points to the fact that OpenStackers Dell and Cisco are happy OpenNebula users. Other users, by the way, range from CERN, Fermilab, the European Space Agency and NASA to BlackBerry, China Mobile, Telefonica and Akamai. — OpenNebula 4.0 guns for the vCloud crowd — Tech News and Analysis
The way I think about this is the “fat middle.” In each industry - say, news - we’ve had the dominant head (New York Times) and long tail (round robin newsletters). In music? Dominant head of stadium tours and U2, and the long tail of bar gigs. The internet’s flattened the curve, and a fat middle has arisen. In news, major blogs: Engadget, the Verge, etc. Music: see all of YouTube. — Orbits and hardware ( 9 May., 2013, at Interconnected)
We are continually evaluating other operating systems that we can enable with [Google] Compute Engine. However, going forward, Debian will be the default image type for Compute Engine. We look forward to hearing your feedback. — Google App Engine Blog: Bringing Debian to Google Compute Engine
Peter Thiel, expressing his dissatisfaction with technology’s progress, recently noted, ‘We wanted flying cars, instead we got 140 characters.’ Do you agree with him?
I feel sorry for Peter Thiel. Did he really want flying cars? Flying cars are not a very efficient way to move things from one point to another. On the other hand, 20 years ago we had the idea that information could become available at your fingertips. We got that done. Now everyone takes it for granted that you can look up movie reviews, track locations, and order stuff online. I wish there was a way we could take it away from people for a day so they could remember what it was like without it.

So – why doesn’t all storage hardware come in “pure software + bring your own hardware” flavors?
I think we will see this over time, but there is something in storage land which is a little unique. Persistence. The storage layer in IT is where the data lives. It’s why the worst days in IT land are when something goes wrong with this persistence layer. It’s also why “mature” storage stacks are so valued (it takes 5 non-compressible years to harden the persistence and data services layer of a block stack, and about 7 years to do the same for a filesystem stack). This is why you see so many ZFS startups – they are leveraging a mature filesystem stack to try to jumpstart.
BTW – the hardest persistence stacks to engineer are DISTRIBUTED persistence block and NAS stacks (which is why they are rare, and so valued). — Under the covers: Storage Virtualization Platform Re-imagined. - Virtual Geek
Open vStorage introduces The Cloud Storage Router, a Software Defined Storage layer that installs on any x86 hardware or can be used as a Virtual Storage Appliance with VMware or OpenStack. The Cloud Storage Router works with a very fast location based storage model close to the hypervisor (vStorage Accelerator) by making use of intelligent caching on Flash or SSD to deliver high performance storage characteristics.
The Cloud Storage Router includes the vStorage Initiator that creates vStorage Containers, delivering the data as optimized storage blocks to the vStorage Distributor that can distribute the data over different storage backends: an object can be stored distributed over different x86 hardware units that reside within the same datacenter, in a branch office or even remote over the WAN with Amazon S3, Google Cloud Storage and many more. Like this, users will benefit from features like unlimited zero copy snapshots, cloning and easy replication. Customers can as well move machines in between clouds, even when underneath different hypervisors are used!
Just storing data and offering handy features is not enough. The vStorage Protector checks data integrity regularly, optimises data sequences and corrects errors automatically. This protects customers against issues like bit rot or corrupt data.
Optionally, the vStorage Distributor includes a built-in Compressor, Encryptor and Erasure Coder.

Since then, I’ve heard this story repeated a thousand times. So many times, I had assumed it was true. But Jimmy Stamp over at Smithsonian points to evidence released by Japanese researchers that, in fact, the story is bunk. The QWERTY keyboard did not spring fully formed from Christopher Sholes, the first person to file a typewriter patent with the layout. Rather, it formed over time as telegraph operators used the machines to transcribe Morse code. The layout changed often from the early alphabetical arrangement, before the final configuration came into being. — The Lies You’ve Been Told About the Origin of the QWERTY Keyboard - Alexis C.
