Why open infrastructure matters in the cloud

Grazed from OpenSource. Author: Jason Baker.

When reading a recent article by Red Hat CEO Jim Whitehurst, I was struck by a comparison made between OpenStack and the interstate highway system. The article in Wall Street and Technology, called "OpenStack: Five things every executive needs to know," mostly focused on the high points of where OpenStack is in its development cycle. But the highway analogy stuck with me.

Part of what made the interstate highway system successful was its standardization and its open nature. "Unlike the early days of the railroads, where track gauges differed and companies refused to interconnect their networks, interstates are open to all who wish to use them," Whitehurst writes. Signage, road widths, and most other components of the system remain generally familiar as one moves from state to state and region to region, with some minor but acceptable variation...

Cloud Computing: Microsoft open sources Windows Library for JavaScript

Grazed from ITWorld. Author: Joab Jackson.

Potentially helping developers more quickly build cross-platform applications, Microsoft is releasing as open source its WinJS JavaScript library for building Windows-styled controls. Now that the library is open source, developers can use it to build and design Windows-like Web applications for other browsers and platforms, including Chrome, Firefox, Android, and iOS.

Such cross-platform capability could save developers time by eliminating the need to code the same app multiple times for non-Windows platforms and browsers other than Internet Explorer, according to the company. While the name "WinJS" may imply that it is a Microsoft version of JavaScript, it is in fact a collection of JavaScript tools for enabling advanced components and user interface controls, which minimize the changes developers have to make for using these features across different devices...

Pivotal opens up Cloud Foundry to open-source fights

Grazed from InfoWorld. Author: David Linthicum.

Pivotal spun out the Cloud Foundry Foundation last week, marking another instance where a commercial effort turns into an open source play. It'll be interesting see how this move works, given that both OpenStack and Red Hat's OpenShift PaaS platforms are aimed at the same users. There are three hurdles for the CFF to get past:

  • The PaaS market is relatively small compared to the IaaS and SaaS spaces. Having three or more open source standards may be too many for the market to support.
  • IT organizations and developers are already confused about what PaaS brings to the cloud computing table. Having three open source versions won't help clarify matters.
  • Inevitably, somebody will end up on the right side of the wrong standard, adding risk for those adopting PaaS...

Linux Foundation Promotes KVM Open Source Cloud Virtualization

Grazed from The Var Guy. Author: Christopher Tozzi.

Open source virtualization for the cloud is at the center of the Linux Foundation's latest move. This week, the nonprofit group announced the addition of seven new organizations that will become partners in the recently launched Open Virtualization Alliance (OVA) initiative, which promotes virtualization solutions based on the open source KVM hypervisor.

The organizations, which represent the latest additions to the Linux Foundation consortium, are Autonomic Resources, Bloombase, BlueCat Networks, op5, Proxmox Server Solutions GmbH, Scale Computing and 6WIND. With legal, financial and advocacy support from the Linux Foundation, these organizations will collaborate to support the OVA, whose goal is to promote virtualization solutions for the cloud that are based on KVM (short for "kernel virtual machine") as "an alternative to expensive, proprietary virtualization solutions."...

Cloud Computing: OpenNebula Celebrates Its 6 Year Anniversary!

Grazed from Sys Con Media.  Author: Ignacio Llorente.

Time flies, and we are once again celebrating our anniversary. Let me take advantage of this opportunity to describe the progress of the project during the last 6 years by using the slides of the opening talk "Unleashing the Future of Open-source Enterprise Cloud Computing" in the first OpenNebula Conference held in Berlin one month ago.

Our Vision: Flexible Enterprise Cloud Made Simple

"Simplicity is the ultimate sophistication", Leonardo da Vinci

When the OpenNebula project started in 2008, we intended to create an open solution to make Enterprise Cloud simple. From the beginning, we understood enterprise cloud computing as en evolution of data center virtualization to host both cloud-aware and traditional applications. So we aimed to combine existing virtualization technologies with multi-tenancy, automatic provision and elasticity, following a bottom-up approach driven by the real-life needs of sysadmins and devops, and the following main principles:...

Heroku Doubles Down On Open Source Database Cloud

Grazed from Wired. Author: Klint Finley.

One of the goals of cloud computing is to cut down on the work it takes to maintain a company’s underlying hardware and software infrastructure. Servers are virtualized, and tools like Puppet and Chef make it easier to manage and configure hundreds or even thousands of servers. Everything from application design to storage management is being rethought thanks to the cloud.

Database management systems are no exception. has been particularly bullish on a database called PostgreSQL, an open source alternative to Oracle’s flagship database products that can also compete with so-called “NoSQL” databases modeled on the mega-data storage systems created by the likes of Google and Amazon. This year, Salesforce hired Tom Lane, one of the core contributors to Postgres, to develop the open source project and build some internal projects for the company...

Inktank Brings Ceph Open Source Cloud Storage to the Enterprise

Grazed from The Var Guy. Author: Christopher Tozzi.

Ceph, the open source, scalable, software-defined storage platform for the cloud and Big Data, is officially ready for the enterprise. That's what Inktank, the company behind the system, has indicated with the release of Inktank Ceph Enterprise, which is now publicly available.

Inktank is offering the solution on a subscription basis. It offers support services and value-added deployment tools related to the Ceph platform, which itself is free and open source, and features Ceph version 0.67, which includes important enterprise functionality such as copy-on-write and compability with the Swift API, as well as a graphical management application aptly named Calamari...

Open Source Software-Defined Storage Platform Ceph Gains Ground

Grazed from The Vary Guy. Author: Christopher Tozzi.

Ceph, the open source, software-defined storage platform that is contending for its share of the rapidly evolving market for distributed storage systems for the cloud and Big Data, has chalked up a significant victory at the University of Hawaii at Manoa. Inktank, the company behind Ceph, partnered with the university's College of Education to deploy a private cloud powered by Ceph, OpenStack and Ubuntu Linux to support research activities.

Mirantis, an OpenStack systems integrator, collaborated with Inktank in the deployment, which the vendors achieved using existing hardware at the university. The private cloud that they built was designed to make it easy for university faculty to deploy new server instances quickly. The infrastructure also ensured data privacy by storing information on-premise rather than in a public cloud...

Cloud Computing: Open source virtualization software still trails, despite improvements

Grazed from TechTarget.  Author: Colin Steele.

Open source virtualization is still a niche technology, despite the rise of multi-hypervisor infrastructures.  Recent open source virtualization software releases have packed in new features with impressive specs, and there’s a clear appetite for VMware Inc. alternatives in enterprise data centers.

One might think these two factors would combine to provide a major boost in open source virtualization’s market share, but that hasn’t happened. Among VMware competitors, only Microsoft’s proprietary Hyper-V has benefited, according to data and several solution providers and analysts who work with multi-hypervisor clients...

OpenStack Celebrates 3 Years of Building Open Source Cloud Platform

Grazed from CIO. Author: Thor Olavsrud.

Today, OpenStack turns 3. The open source Infrastructure as a Service (IaaS) platform, released under the Apache license, launched in July 2010 with a seemingly simple idea: to deliver a ubiquitous open source cloud computing platform for public and private clouds. Launched in July 2010 with code donated by Rackspace and NASA, OpenStack has become one of the fastest growing open source efforts in technology: More than 500 individuals from more than 200 different companies contributed to its latest release, Grizzly.

Developers have contributed more than 1 million lines of code, and the stack currently has more than 70,000 contributions from more than 120 countries—an average of 238 contributions per month. The first OpenStack Design Summit & Conference, held in July 2010, boasted 75 attendees. The most recent conference, held in April, had 3,000, and the next one is expected to have more...
