Introduction: In A Brief History of the Internet it was revealed that the Internet was based on the idea that there would be multiple independent networks of rather arbitrary design. The Internet as we now know it embodies a key underlying technical idea, namely that of open architecture networking. In this approach, the choice of any individual network technology was not dictated by a particular network architecture but rather could be selected freely by a provider and made to interwork with the other networks through a meta-level "Internetworking Architecture". With the cloud we are in the same situation today, just a layer or two higher up the stack. We have independent clouds that we would like to connect and work seamlessly together, preferably with the ease at which we currently connect nodes to a network and networks to the Internet. This technology seems to be called the Intercloud : an interconnected global "cloud of clouds " as apposed to the Internet which is a "network

3 " Vinton Cerf, person most often called the father of the Internet , says in Cloud Computing and the Internet that we are ripe for an Intercloud in the same way we were once ripe for the Internet: Cloud computing is at the same stage [pre-Internet]. [sent-7, score-0.413]
4 There is no way to express the idea of exchanging information between distinct computing clouds because there is no way to express the idea of “another cloud. [sent-9, score-0.718]
5 Moreover, if the information contained in one computing cloud is protected from access by any but authorized users, there is no way to express how that protection is provided and how information about it should be propagated to another cloud when the data is transferred. [sent-11, score-1.043]

13 The semantics of data and of the actions one can take on the data, and the vocabulary in which these actions are expressed appear to me to constitute the beginning of an inter-cloud computing language. [sent-30, score-0.395]
14 The paper's abstract gives a good overview of their approach: Cloud computing providers have setup several data centers at different geographical locations over the Internet in order to optimally serve needs of their customers around the world. [sent-37, score-0.295]
15 Further, the Cloud computing providers are unable to predict geographic distribution of users consuming their services, hence the load coordination must happen automatically, and distribution of services must change in response to changes in the load. [sent-39, score-0.427]
16 To counter this problem, we advocate creation of federated Cloud computing environment (InterCloud) that facilitates just-in-time, opportunistic, and scalable provisioning of application services, consistently achieving QoS targets under variable workload, resource and network conditions. [sent-40, score-0.265]

18 Constructed on high level stateful services like brokers and coordinators, the Intercloud infrastructure is very specialized. [sent-51, score-0.195]

Introduction: Update: InfoQ links to a few excellent Eucalyptus updates: Velocity Conference Video by Rich Wolski and a Visualization.com interview Rich Wolski on Eucalyptus: Open Source Cloud Computing . Eucalyptus is generating some excitement on the Cloud Computing group as a potential vendor neutral EC2 compatible cloud platform. Two reasons why Eucalyptus is potentially important: private clouds and cloud portability: Private clouds . Let's say you want a cloud like infrastructure for architectural purposes but you want it to run on your own hardware in your own secure environment. How would you do this today? Hm.... Cloud portability . With the number of cloud offerings increasing how can you maintain some level of vendor neutrality among this "swarm" of different options? Portability is a key capability for cloud customers as the only real power customers have is in where they take their business and the only way you can change suppliers is if there's a ready market of fun

Introduction: Loved those mainframe days – you only needed one, but then came along the AS400’s and soon you had ten – but wait, you needed client server and SOA, oh sh%# – now I have ten thousand servers and I need to consolidate server and datacenter operations! Is Cloud Computing going to follow the same path? As a technology strategist I have the benefit of frequently speaking with other CIO’s on the topic of Cloud Computing. Often those discussions are in context to how they can leverage SpringCM’ s easy, fast and affordable cloud Enterprise Content Management (ECM) services. But those conversations are done in context to the overall strategy and reality that the modern CIO will use a combination of cloud offerings to solve business problems today. Some of those services will be internally provided (Private Cloud), and many more will be outside the traditional corporate domain, also known as Public Cloud services. What options do I have? In a recent conversation with a CIO represen

1 0.93848032 1127 high scalability-2011-09-28-Pursue robust indefinite scalability with the Movable Feast Machine
Introduction: And now for something completely different, brought to you by David Ackley and Daniel Cannon in their playfully thought provoking paper: Pursue robust indefinite scalability , wherein they try to take a fresh look at neural networks, starting from scratch. What is this strange thing called indefinite scalability ? They sound like words that don't really go together: Indefinite scalability is the property that the design can support open-ended computational growth without substantial re-engineering, in as strict as sense as can be managed. By comparison, many computer, algorithm, and network designs -- even those that address scalability -- are only finitely scalable because their scalability occurs within some finite space. For example, an in-core sorting algorithm for a 32 bit machine can only scale to billions of numbers before address space is exhausted and then that algorithm must be re-engineered. Our idea is to expose indefinitely scalable computational power to program

You feel like this (it uses some language picante so be advised): Here's a link to the source: http://browsertoolkit.com/fault-tolerance.png A great way to communicate the dislocation one feels when technology changes. It also gets you to wonder if those changes at the user level are completely necessary for carrying out the task?

He’s focusing on data center and cloud networking, network virtualization, and scalable application design. OpenFlow is an interesting emerging networking technology appearing seemingly out of nowhere with much hype and fanfare in March 2011. More than a year later, there are two commercial products based on OpenFlow ( NEC’s Programmable Flow and Nicira’s Network Virtualization Platform ) and probably less than a dozen production-grade implementations (including Google’s G-Scale network and Indiana University’s campus network ). Is this an expected result for an emerging technology or another case of overhyped technology hitting limits imposed by reality? OpenFlow-based solutions have to overcome numerous problems every emerging technology is facing, in OpenFlow’s case ranging from compatibili

Introduction: It's a sad fact of life, but processes die. I know, it's horrible. You start them, send them out into process space, and hope for the best. Yet sometimes, despite your best coding, they core dump, seg fault, or some other calamity befalls them. Unlike our messy biological world so cruelly ruled by entropy, in the digital world processes can be given another chance. They can be restarted. A greater destiny awaits. And hopefully this time the random lottery of unforeseen killing factors will be avoided and a long productive life will be had by all. This is fun code to write because it's a lot more complicated than you might think. And restarting processes is a highly effective high availability strategy. Most faults are transient, caused by an unexpected series of events. Rather than taking drastic action, like taking a node out of production or failing over, transients can be effectively masked by simply restarting failed processes. Though complexity makes it a fun problem, it's also
