Cloud Computing Defined

Early Bird Savings at Cloud Expo (September 12, 2008) - Originally, Cloud Computing was a vague term for a very vague and distant future in which computing would occur in a few remote locations without the need for very much human intervention. Infinite computing resources would be available for any need at costs approaching zero. Certainly, users would not need to know or care about how the computers, their software, or the network functioned. In the real world, physical computing progressed differently. We cycled between periods when computing was more centralized (and seemed more remote and less accessible to users) and other periods when computing was right on user desktops. No one was ever satisfied. Centralized computing failed to give users enough control and was too inflexible. Distributed computing made every user his own system administrator and was very i...

VMware’s Newfangled Cloud OS Positioned for Takeoff

VMware is scheduled today to announce the industry’s first cloud operating system ahead of delivering the thing sometime before the end of June. Branded vSphere 4, the expected widgetry, which promises a 100% virtualized cloud, is meant to reinforce VMware’s virtualization leadership and push it out further ahead of Microsoft, which is nipping at its heels. VMware has, for instance, segmented the stuff so that the low end is now priced considerably lower than its current generation to attract SMBs lest Microsoft pick them off with its “freeware.” Meanwhile vSphere’s feature-packed upper end will court the enterprise and the hosting service providers. vSphere is the basis of what VMware calls a private cloud and defines not just as an internal cloud but rather as an internal cloud federated with an external cloud or clouds for added capacity. VMware CTO Steve Herrod k... (more)

Scalable HTTP Session Management with WebSphere Extreme Scale (WXS)

HTTP session management is a function offered by Java Enterprise Edition (JEE) application servers. It allows JEE applications to store state information about a given user across many HTTP requests. The JEE specification provides an API to store and retrieve information specific to the given user. WebSphere application servers and other competing products, provide session replication functionality. This is normally done either by writing to a database or through memory-to-memory replication technology.  These approaches while extensively used today, have operational challenges and cost implications. HTTP session replication enables for seamless session recovery, in event of an application failure, but we currently do not have a reliable, predictable and cost effective solution to handle session recovery in event of a data center failure. Until now we have discourag... (more)

Something You May Not Know About IBM and Cloud

Ask someone to associate IBM and cloud computing, and that person will probably come back with something about solutions to help build private clouds. I know because I ask... all the time. On the surface, this is a fair association. After all, it is true that IBM offers quite a few different solutions that help users to build both private clouds and on-premise clouds that they then offer up to others (i.e. enabling service providers). However, it does not participate in this cloud delivery model at the expense of other delivery models. In fact, IBM has a wide-breadth of cloud solutions, including those that fit in private, hybrid, and yes, even public cloud categories. While it may be the case that the private, and thanks to a recent high-profile acquisition, hybrid cloud solutions are the best known of the bunch, it is a misperception to characterize IBM as only f...

Java vs C++ "Shootout" Revisited

Keith Lea writes of the benchmark, on his results page, "I was sick of hearing people say Java was slow, when I know it's pretty fast, so I took the benchmark code for C++ and Java from the now outdated Great Computer Language Shootout and ran the tests myself." Lea used G++ (GCC) 3.3.1 20030930 (with glibc 2.3.2-98) for the C++, with the -O2 flag (for both i386 and i686). He compiled the Java code normally with the Sun Java 1.4.2_01 compiler, and ran it with the Sun 1.4.2_01 JVM. He ran the tests on Red Hat Linux 9 / Fedora Test1 with the 2.4.20-20.9 kernel on a T30 laptop. The laptop "has a Pentium 4 mobile chip, 512MB of memory, a sort of slow disk," he notes. The results he got were that Java is significantly faster than optimized C++ in many cases. "They also show that no one should ever run the client JVM when given the choice," Lea adds. ("Everyone has the c... (more)

Where Are RIA Technologies Headed in 2008?

I am always being told off by i-technologists for quoting Picasso as having said that computers are useless. But I still love his reasoning? "Because they can only give you answers." Picasso, like AJAXWorld Magazine, liked questions. So we thought we would share with you what some of the world's leading rich Internet application pioneers are thinking may be the next questions that we need to see answered. From that readers can themselves infer where AJAX is headed. What are the top questions to ask next about AJAX? Eric Miraglia of Yahoo! 1.  (From March'08) How do I calculate the ROI of building my RIA on the iPhone SDK vs using AJAX? 2.  How do I assess the performance of my app and decide what to do next to make it faster?  3.  When it comes to accessibility, how do I know what's required of me for my rich web apps?  Beyond what's required, what makes good business se...

Unveiling the java.lang.Out OfMemoryError

When we encounter a java.lang.OutOfMemoryError, we often find that Java heap dumps, along with other artifacts, are generated by the Java Virtual Machine. If you feel like jumping right into a Java heap dump when you get a java.lang.OutOfMemoryError, don't worry, it's a normal thought. You may be able to discover something serendipitously, but it's not always the best idea to analyze Java heap dumps, depending on the situation you are facing. We first need to investigate the root cause of the java.lang.OutOfMemoryError. Only after the root cause is identified can we decide whether or not to analyze Java heap dumps. What is a java.lang.OutOfMemoryError? Why in the world does it occur? Let's find out. What Is a java.lang.OutOfMemoryError? A java.lang.OutOfMemoryError is a subclass of java.lang.VirtualMachineError that is thrown when the Java Virtual Machine is broken or... (more)

Cloud Expo and The End of Tech Recession

http://twitter.com/fuatkircaali At SYS-CON Media we see our inventories are filling up to 100% capacity for the months of November, December, and January, and we are seeing better-than-normal RFP activity for the first quarter of 2010. When I say this, I am comparing the current insertion order activity to the same period last year. We will be closing 2009 roughly 32% below 2008 in revenues (far better than any other tech media company), which forced us to reduce our expenses for the same period by around 40%. Last fall, while the world was falling apart, we were preparing for a 40%-45% drop in advertising revenues for 2009. We did better than our worst projections.
