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 …

WHAT IT IS ALL ABOUT Not long ago we’ve been working on deployment of OpenStack Cactus-based public cloud using Xen as an underlying hypervisor. One of the problems we’ve faced were Windows guest instances failing to set up their administrator password to those generated by nova on instance creation. As it turned out the overall process of compute-guest instance communication in …

Recently we've deployed OpenStack Diablo release for one of our customers. The target operating system happened to be CentOS 6.0. During deployment testing we've stumbled upon a number of bugs in OpenStack RPMs that we've tried to use. All existing RPMs of OpenStack that we've found contained problems that prevented components from operating correctly with each other: 1. Incompatible protocol in packaged …

Thanks to WireRE for hosting us, Dave Nielsen – for helping to organize, and all the attendees – for coming. Once again, this was the biggest MeetUp thus far with 150 in attendance.

The simplest way to authenticate a user is to ask for credentials (login+password, login+keys, etc.) and check them over some database. But when it comes to lots of separate services as it is in the OpenStack world, we have to rethink that. The main problem is an inability to use one user entity to be authorized everywhere. For example, a …

Cloudpipe is used in OpenStack to provide access to project’s instances when using VLAN networking mode. It is just a custom Virtual Machine (VM) prepared in a special way, i.e. coming with an accordingly configured openvpn and startup scripts. More details on what cloudpipe is and why it is needed are available in OpenStack documentation. The process of creating an image …

Historically, commercial software provided enterprises with reliability and scalability, especially for mission-critical tasks. No one wanted to risk failure in finance, operations, or any essential or enterprise-wide areas. So, enterprises considered open source technology only for less important, more tactical purposes. Recently, however, many large IT organizations have developed significant open source strategies. Cisco, Dell, NASA, and Rackspace came together to …

How enterprises are progressing from overgrown, difficult-to-manage IT systems to high performance open source infrastructure Over the history of computing, we can trace a pattern of continuous decomposition, from a single system into disparate components. Early on, these individual parts made it easier to design, program and maintain systems, and meet the fast-growing demand for more power and more capacity. The industry …

Here are the highlights on our corporate team-building in Vegas last week. Special thanks to Rachel and Athena for making this party happen. Thank you to all who participated and helped make it fun. We started by warming up with some drinks in the airport bar on the way over to Vegas. The luggage belt broke upon our arrival and it took …

After some time working with OpenStack installation using existing LDAP installation for authentication, we encountered one big problem. The latest Dashboard code dropped support of old bare authentication in favor of Keystone-based one. That time Keystone had no support for multiple authentication backends, so we had to develop this feature. Now we have a basic support of LDAP authentication in Keystone …

For those of you that weren’t able to make it yesterday and maybe for those of you who want to reminisce about the events of last night, Bay Area OpenStack Meet & Drink was probably the most well-attended OpenStack meetup in the valley to date, outside of the OpenStack summit this spring. A diverse crowd of over 120 stackers showed …
