Docker.io have used their inaugural DockerCon event to launch version 1.0 of their container management tools. It comes just days after the release of 0.12.0, which was focussed on stability, performance and usability rather than introducing significant new features. Production readiness means that Docker.io is now providing support services for Docker.
Microsoft continues to invest in PowerShell, its command-line shell and associated scripting language. PowerShell Desired State Configuration (DSC) can now manage Linux boxes in the same vein as it does for Windows. Microsoft open source DSC for Linux and is hosting the project at GitHub.
Docker version 0.11 has been released, which is the first release candidate for 1.0. The release doesn’t just focus on stability, and includes a number of new networking, security and administration features.
TechEmpower has been running benchmarks for the last year, attempting to measure and compare the performance of web frameworks. For these benchmarks the term “framework” is used loosely including platforms and micro-frameworks.
Google has announced that its Andromeda network virtualization stack is now live in two Google Compute Engine (GCE) zones (us-central1-b and europe-west1-a) with other zones being migrated in coming months. Andromeda offers significant performance improvements without requiring any reconfiguration by Google Cloud users.
With the release of version 0.9 Docker.io have dropped LXC as the default execution environment, replacing it with their own libcontainer. At the same time Docker now supports a much broader range of isolation tools through the use of execution drivers, which include: OpenVZ, systemd-nspawn, libvirt-lxc, libvirt-sandbox, qemu/kvm, BSD Jails, Solaris Zones, and chroot.
As part of the 0.8 release the Docker.io team have announced support for installation on Mac OS X and the use of the BTRFS as an alternative to AUFS.
Jérôme Petazzoni, senior engineer at dotCloud, examined the progress of security concerning Docker compared with other virtualization and container like technology in his recent blog post "CONTAINERS & DOCKER: HOW SECURE ARE THEY?". Jérôme makes a case for the techniques that secure Docker, in spite of the acknowledgement that improvements are needed.
This weekend, Debian celebrated its 20th anniversary, making it the oldest Linux distribution still in existence. Read on to find out a little bit more about where Debian came from.
Crypto Obfuscator for .Net v2013 R2 includes support for code masking, constant field removal, Visual Studio 2012. It also includes Linux and Mono support for automatic exception reporting service including several new additions, improvements, changes and bug fixes.
Most users of Amazon EC2 use the service inefficiently with only a 15% utilization of the infrastructure. The most effective way to use EC2 is by running many applications in large memory reserved instances. James Watters describes how the new architecture of Cloud Foundry uses Linux Control Groups to optimise efficiency and reduce costs by up to a factor of 10.
GCC has become fully implemented in C++ in its new 4.8 release, but the improvements aren't solely internal. The compiler has increased support for C++11, Google's Go, and new compiler optimizations.
dotCloud, a PaaS provider, has open sourced Docker, a key component of their platform. Docker is a LinuX Container (LXC) technology augmented with a a high level API providing a lightweight virtualization solution that runs Unix processes in isolation. It provides a way to automate software deployment in a secure and repeatable environment.
Microsoft Open Technologies unveiled their first major offerings in the form of a repository for pre-configured virtual machines that can be quickly deployed to the Windows Azure cloud. The VM Depot is advertised as a place to discover and deploy Azure-friendly virtual machines, and may be Microsoft’s answer to the popular catalog provided for AWS users.
