Linux and Open Source technology
OpenStack started out as an open source project by RackSpace and NASA in 2010. It was designed to enable any organization to run cloud services on standard hardware. IT industry companies like AMD, Intel, Red Hat, Cisco, Dell, HP, IBM, VMware, Yahoo and a bunch of others have joined the project. OpenStack is a suite of interrelated software packages that control processing, storage and networking resources throughout a datacenter. Administrators can manage these resources through a web accessible dashboard, and users can provision resources themselves. All of the code for OpenStack is freely available under the Apache 2.0 license. Anyone can run it, build on it, or submit changes back to the project.
Platform-as-a-Service is getting a lot of press lately, and with good reason. PaaS is an efficient way to develop applications, as you can start up a new development machine in a matter of seconds and take it down when you're finished with it. Or cater to specific needs easily, such as combinations of framework versions and databases.
Red Hat's Openshift is such a Platform-as-a-Service, ready for production after two years of beta testing.
In a short interview, Jim Whitehurst, CEO of Red Hat, talks about the changing role of the CIO. Real innovation happens with big data and cloud APIs based on open source. At the same time, the expectations of the CIO and the IT department are defined by big companies such as Apple, Google and Facebook, while the CIO has to migrate from expensive legacy infrastructure systems.
Zimbra started out as an open source project back in 2006, focusing on improving email collaboration. Zimbra is the collaboration and communication engine behind 85 million commercial mailboxes across 250 000 organisations worldwide, which makes it the number three email application behind Exchange and Gmail. Since 13 September 2013, Zimbra 8 is available to the public. Based on feedback from customers, VMware has invested lots of effort into unified communications, cloud integration and easier mobile user experience. We upgraded to Zimbra 8, read on for our opinion. Or ask us to show you a demo through a web conference.
The main idea behind Arch Linux: provide a distribution which keeps things as simple as possible. A good example is the way they replace the classic sysv init system with a simple array of values. No upstart, no systemd, no tools necessary to create start/stop symlinks. The order in which you place the names of the init scripts, is the order in which they are started. Simple, no?
