Java is currently the leading exploit vector for Windows machines, and Java vulnerabilities are packaged into many of the “exploit kits” available in the darker corners of the Internet (see http://krebsonsecurity.com/2010/10/java-a-gift-to-exploit-pack-makers/). Internet Explorer, Flash Player, and even the Windows operating system itself have done a good job of either improving the security of their products or …

News: PaaSLane 2.0 — Letting Applications Take Advantage of the Cloud
PaaSLane from Cloud Technology Partners is a tool that greatly facilitates the process of migrating an application to the cloud by comparing its source code to known safe best practice. It claims a 25% enhancement in migration time. We suspect that in many cases this will easily be achieved, plus PaaSLane removes a lot of …

PaaSLane: Ensure Your Software Will Run on AWS
Cloud Technology Partners has just released its new PaaSLane for AWS, a software solution that analyses codebases and pinpoints issues that would likely cause problems if the code were to be deployed to Amazon Web Services or other elastic environments.
CloudFoundry Apps not VMs
VMware’s latest effort, CloudFoundry, is not about VMware delving into the PaaS market even deeper. They have done that already with VMforce. CloudFoundry on the other hand is a fairly astute move to enable the development and rapid adoption of cloud based applications. The end goal is to sell what makes up a PaaS environment which is more enabling software. This would enable enterprises and businesses to move to the cloud. The problem with them moving now is that there are not that many applications that are cloud friendly. In effect more concentration on the application and less on the operating system which has always been VMware’s strategic direction.
Virtualize Java without an Operating System
When we put a .NET application on Windows on Hyper-V (or a Java application on Linux on ESXi) we are actually virtualizing twice. Can we virtualize only once, by putting the CLR or the JVM directly on the VM Host? In this action of course we remove the operating system. Oracle is taking the lead in this area with JRockit VE JVM. There is no VMware support, the only hypervisor it supports is Xen, or more precisely Oracle VM. it only comes bundled only with an Application Server, namely Oracle WebLogic Suite Virtualization Option. The entire stack inside the virtual machine is in “User Mode” in other words the JVM and the drivers are all in the same memory address space and you don’t need to switch contexts into Kernel Mode in order to perform I/O or network access. Does VMware have a strategic initiative (or even a skunkworks) to engineer a similar bundle for its SpringSource runtimes? Or are they just concentrating on scaling out with as per the Google announcement?
Development Tools and Application Servers for the Cloud
Development tools like Eclipse and Visual Stuio are being built to ensur applications can be deployed in to the cloud on application servers. Key challenges include the manageability and scalability of application servers. Innovations include the use of non-java languages like Groovy and Jython and even PHP and Javascript on JVMs, and the final demise of SQL as object caches offer more natural scalability.
