The power of open source is incredible. Don’t believe me? Click here or here Contribution is something that makes open source projects most powerful. It has been proven with Linux a long time ago. Also, giant companies have started to … Continue reading ...
Background
In a Eucalyptus HA configuration there are two Cluster Controllers's (CC) which are in an active-passive state. One is in "ENABLED" mode and one is "DISABLED" mode. If a failure occurs, the active CC services moves to the secondary CC system.
If you combine this with Eucalyptus MANAGED or MANAGED-NOVLAN networking configuration with a private back-end network your Node Controllers (NC) will require a default gateway for access to external networks and to the Walrus...
Reblogged from Greg DeKoenigsberg Speaks: We’re big fans of the Cobbler project here at Eucalyptus. We think it’s the best tool in the open source world for bare metal provisioning. We’ve invested in a gigantic QA environment for continual integration testing, and Cobbler is one of the linchpins of that environment. It’s the kind of [...]...
We’re big fans of the Cobbler project here at Eucalyptus. We think it’s the best tool in the open source world for bare metal provisioning. We’ve invested in a gigantic QA environment for continual integration testing, and Cobbler is one of the linchpins of that environment. It’s the kind of tool that’s best appreciated by sysadmins who deal with *a lot* of systems.
I’m sort of attached to Cobbler personally, since I watched it grow out of Red...
For the 3.2 release in this December, Eucalyptus is coming out with an intuitive, easy-to-use cloud user console, which aims to support the on-premise dev/test cloud adoption among IT organizations and enterprises.

Sometimes preparing for a cloud project can feel like staring up at Everest from basecamp. Getting started is always daunting when you don’t quite know how to take the first step.
While we’re still in the dawn hours of the proverbial cloud day, one pattern has become evident for many enterprise IT organizations: You start with a private cloud. And when you roll out your cloud, you look to development and test functions as your initial use cases. This is the beachhead for the cloud...
At Eucalyptus, IT tends to have a bunch of different accounts for the clouds that we run. Most of the work we do with these clouds happens from the Cloud Controller of each cloud and it can become confusing determining which user’s credentials are currently sourced when you have 10 accounts and 15 users. We need a method for easily determining which account and user we are currently accessing the cloud as so that we don’t launch instances or create keypairs using the incorrect user as then...
So, the second post in this series and now a look at Eucalyptus Elastic Block Storage (EBS) and the Eucalyptus Storage Controller (SC) component which handles this.
What does it do?
The Storage Controller sits at the same layer as the Cluster Controller (CC), each Eucalyptus Availability Zone (AZ) or Cluster will have its own CC and SC. Within that AZ, the SC will provide EBS (Elastic Block Store) functionality via iSCSI (AoE is no longer used in 3.0 onwards) using the Linux...
I previously posted some information about the new User Console we’ve been working on at Eucalyptus Systems. There has been a lot of activity and we’ve shown it to a lot of users to get feedback. We will be releasing it officially very soon, but till then, you can run it yourself a couple of ways. You can build from source, which is very easy, or install nightly builds which we provide for RHEL 6 and...
