Is the Nicira acquisition good for OpenStack? Definitely. But before I defend my assertion, let's look at why this is good news. I'll start with Microsoft (though the old-school tech guys who need to pay attention are at Cisco; more on that in a moment). Microsoft don't get no respect in the infrastructure business -- not least when it comes to …

This week Boris Renski and I are visiting OSCON 2012 in Portland, OR. So far it's been a lot of fun. One of the guys we met here was Lucas Carlson, CEO of AppFog, who gave us an invitation to join their contest. The rules were very simple. You had to write an obfuscated program which outputs "Happy Birthday OpenStack", and …

Today I am at the OpenStack day at OSCON… spending the day chatting with developers and OpenStack community stakeholders. Here are some real-time thoughts, directly from the trenches of the open source ecosystem… There appears to be many disagreements about code maturity of the OpenStack projects and the number of OpenStack production deployments. However, everybody agrees that OpenStack community of actively …

Overview When using cloud storage, such as OpenStack Swift or Amazon S3, at some point you might face a situation when you have to upload relatively large files (i.e. a couple of gigabytes or more). For a number of reasons this brings in difficulties for both client and server. From client point of view, uploading such a large file is quite …

One of my favorite business-technology-society-history books is The Machine that Changed the World, by a bunch of guys from MIT -- Womack, Jones, et al. In it, they describe the technological and organizational breakthroughs behind what we now know as lean, that revolutionary, begin-with-the-end-in-mind approach that drives agile thinking and end-user centric design, engineering and production processes. It originated radical …

If you've ever tried to explain what you do for a living for someone who's not in tech, you've probably been challenged to make it relevant to their day-to-day life. Steve Jobs did a lot to ameliorate that. But even as we are accustomed to the rate of transformations made possible by the technology we all work on, people outside of …

A couple of weeks ago, just before GigaOM Structure (the cloud equivalent of short Indian Wedding), Twitter and the headlines rang out with the news that NASA, home of the space program, the Apollo moonshot, the International Space Station, and the space shuttles, was retiring yet another of its signature innovations: OpenStack. According to Information Week's headline, "NASA Drops OpenStack …

Call it what you will -- the Davos of Cloud, the Big Chill of cloud buzz, you name it -- our friends at GigaOM have put together a terrific lineup of big time clouderati at the Structure conference next Wednesday June 20th and 21st. A lot of these guys are the real deal -- Adrian Cockcroft of Netflix is an old friend …

Over the course of the last 18 months, I’ve spent a bit of time as a booth bunny at shows like OSCON, Structure, CloudConnect etc. helping evangelize OpenStack. A fairly common conversation opener thrown by people expressing interest goes something like this: “We are currently using VMware, but it is too expensive… tell me how can OpenStack help?” To this date, …

CloudStack: OpenStack Rebels versus Citrix Empire. Who will win?

-

After OpenStack was announced at OSCON in the summer of 2010, the degree of momentum behind this new open source platform has been nothing short of spectacular. Startups and enterprises alike have placed their strategic bets to monetize the OpenStack wave in various ways. As an ecosystem insider and one of the founding sponsors of the OpenStack Foundation, I wanted …

When I first heard the announcement about Cloud.com being spun off into the Apache foundation, my initial reaction was to interpret the event as a hostile move by one of the OpenStack community insiders. Citrix is one of the founding members of OpenStack, with representation on the project policy board; the company has been quite active evangelizing the community through …

With Essex train in the wilds of testing, and the Essex release intended date less than 10 days away, we are pretty excited about everyone descending on San Francisco -- practically our home town -- for the Design Summit and conference. Here at Mirantis, the company famous across OpenStack community for distributing vodka bottles at OpenStack meetups, we are gearing up …

One active arena of cloud blog battles lately was about open vs. enterprise clouds. Randy Bias of Cloudscaling is on the forefront of open cloud advocacy with a clear stance thatanything that is not an open cloud - is a legacy cloud. Massimo, in his recent blog did a great job categorizing different types of clouds. He, too, gently implies …

This is the first post in series that summarizes our analysis of Swift architecture. We've tried to highlight some points that are not clear enough in the official documentation. Our primary base was an in-depth look into the source code. The Ring is the vital part of Swift architecture. This half database, half configuration file keeps track of where all …
