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.
Mitchell Hashimoto, creator of Vagrant, gave a talk last month at Velocity Conf London about his vision for a “FutureOps” with immutable infrastructures and built-in failure recovery.
Mirage OS is a ‘cloud operating system’ that seeks to avoid security vulnerabilities and bloat by facilitating the creation of single purpose virtual appliances. Applications are developed in the OCaml functional programming language and compiled into standalone ‘unikernels’ that run directly on the Xen hypervisor.
PaaS provider dotCloud has changed its company name in order to align with the red-hot open source technology it sponsors. Docker, Inc will continue to offer a standalone PaaS product, but is shifting its primary focus to growing and commercializing its namesake software. To get additional insight into the explosive growth of Docker and where the product is going, InfoQ spoke to CEO Ben Golub.
CodeCube is a new service and open source project that aims to improve collaboration by allowing developers to both share and run code samples in a secure manner via the browser.
Juniper Networks have launched their software defined networking (SDN) solution OpenContrail using the permissive Apache v2 open source software license. This means that there is now an open source alternative to VMware’s NSX solution for SDN, which was launched last month at VMworld.
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.
VMware launched new networking and storage capabilities for its Software Defined Data Center (SDDC) at the opening keynote of VMworld 2013, delivering products it promised a year ago.
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.
Netflix deploys a hundred times per day, without the use of Chef or Puppet, without a quality assurance department and without release engineers. To do this, Netflix built an advanced in-house PaaS (Platform as a Service) that allows each team to deploy their own part of the infrastructure whenever they want, however many times they require.
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.
HashiCorp's latest addition to support Amazon AWS and Rackspace as providers for Vagrant enables new usage scenarios: for the first time it will be possible to spin up Virtual Machines in the cloud instead of the developer's desktop.
VMware added $30 million to its initial investment into Puppet Labs, makers of the Open Source configuration management tool Puppet. Commenters seem to agree that its a good move for Puppet Labs and that Puppet will keep supporting any type of infrastructure avoiding vendor lock-in.
Last month, platform-as-a-service (PaaS) provider Engine Yard released a “cloud in a box” that developers can use to test their applications locally before publishing to the public cloud. Multiple cloud providers have now embraced this deployment model as a way to accelerate development while making it easier to try a particular cloud before committing to it.
