With Kubernetes 1.5, it’s finally possible to build a single hybrid clustered application that includes both Windows and Linux components interacting with each other.
On July 8, Red Hat released version 5 of the Red Hat Enterprise Linux OpenStack Platform. RHELOSP 5.0 is based on April’s Icehouse release of OpenStack, plus RH Enterprise Linux 7, and RH Enterprise Virtualization 3.4 — both released last month. The new spin will offer three years of support, double that of RHELOSP 4, released seven months ago.
Network virtualization pioneers Metaswitch Networks announced the launch of Project Calico, to which they’ve contributed the initial codebase under a (permissive) Apache license. Calico uses Layer 3 internet core routing technologies and tools like Border Gateway Protocol (BGP) for route discovery to network VMs and hosts, whole datacenters, and multiple datacenter locations via carrier networks. The Calico project is part of Metaswitch’s Neuron initiative, which provides a continuous framework for Network Function Virtualization (NFV) that meets the needs of both datacenter operators running VM/host architectures with lots of virtualized tenant clusters and networks (i.e., the typical OpenStack use-case), and carriers building extremely high-density data centers that virtualize at Layer 3 and may use container-based (e.g., Docker, Flynn) isolation schemes.
Last Wednesday brought news of RedHat’s impending acquisition of InkTank, spun out of DreamHost in 2012 to help advance the open source, Linux-resident, cloud-friendly Ceph technology — earlier originated at DreamHost by Sage Weil (now InkTank’s CTO) based on PhD research Weil did at UC Santa Cruz’ Storage Systems Research laboratory, under sponsorship by the US Department of Energy.
