We are happy to announce Nimbus Infrastructure 2.10.1 bugfix release!
This is a minor release that fixes a few bugs. Specifically, it updates junixsocket to 1.14. A Java security update necessitated this change. The qcow2 support is also more resilient to hanging qemu_nbd processes.
Users should note that this release will ONLY work with Java 1.6.0 Update 41 and later, which they are strongly encouraged to upgrade to. If for some reason upgrading is impossible, Nimbus Infrastructure 2.10 should continue to work on that release.
Check out the changelog for full details.
We would like to particularly acknowledge the contributions to this release of our partners in the open source community: Michael Paterson and Adam Brust. The features in this release were supported by the Ocean Observatory Initiative and FutureGrid projects.
The Nimbus 2.10.1 release is available on the downloads page.
Documentation (still in progress) is available at: http://www.nimbusproject.org/docs/2.10.1/

We are proud to announce the release of Nimbus cloud-client-021.
Along with some minor improvements and bug fixes the major contributions of this release are:
- Users can now associate meta data describing a virtual machine image along side of their image in the Cumulus repository.
- Users can query the cloud for detailed information about the hardware on which their VM is running. Determining the specific location of VMs has enabled FutureGrid researchers to study scientific computation in infrastructure clouds. In order to use this feature the infrastructure cloud administrator must enable it.
The new release can be found on the Nimbus downloads page.

We are happy to announce the final release of Nimbus Infrastructure 2.8 as well as the first release of Nimbus Platform!
Nimbus Infrastructure 2.8 contains new features that significantly improve VM deployment performance, flexibility of administration and improve compatibility with EC2. In addition, it also contains minor enhancements and bugfixes, see the changelog.
While Nimbus Infrastructure contains tools that allow providers to build clouds, Nimbus Platform focuses on tools that leverage them: provision resources across different infrastructure cloud providers and contextualize them. To achieve this, Nimbus Platform tools are compatible with leading infrastructure cloud implementations. The current release contains two such tools:
- Nimbus Platform Context Broker 2.8: repackaging of the Nimbus Context Broker facilitating its independent use.
- Nimbus Platform cloudinit.d 1.0: a tool for coordinating, monitoring and repair of complex launches over infrastructure cloud providers.
The release is available for download at: http://www.nimbusproject.org/downloads/
Documentation is available:
In addition to the committers, we would like to acknowledge the contributions from Jamie Chen, David Foster, Kyle Fransham, Adam Smith, and Dan Yocum.

We are happy to announce the release candidate of a new Nimbus release!
The star of this release is unquestionably Nimbus Platform: a set of tools that make infrastructure clouds from many providers easier to use. While our focus has always been on providing capabilities for infrastructure outsourcing across the stack, in the last few years Nimbus was best known for its IaaS implementation (Nimbus Infrastructure). With this release we are emphasizing our focus on the “platform layer”: tools that make management of resources across different infrastructure cloud providers easier. Besides to the already familiar context broker, this release contains cloudinit.d – a tool that enables repeatable and coordinated deployment of multiple inter-dependent VMs over many infrastructure clouds. Future Nimbus Platform releases this year will contain tools that facilitate cloud use for automatic scaling and high availability. In addition, this release also contains significant improvements to the Nimbus Infrastructure (see below).
To allow users to flexibly access the best tools for their needs, we also decided to make changes to our packaging and release structure: Nimbus Infrastructure as well as all individual Nimbus Platform tools will be packaged and released separately, inheriting the versioning from their last release. Consequently, this release contains the following downloads:
- Nimbus Infrastructure 2.8, containing several features that improve VM deployment performance and flexibility as well as numerous bugfixes.
- Nimbus Platform Context Broker 2.8
- Nimbus Platform cloudinit.d 1.0
In addition to the committers who all contributed to this release we would like to acknowledge the help from Jamie Chen, David Foster, Kyle Fransham, Adam Smith, and Dan Yocum.
The release is available for download at: http://www.nimbusproject.org/downloads/

Happy (belated) Valentine's Day! From Nimbus, with love -- the final release of 2.7!
The most important new functionality in this release is support for preemptible instances: "spot instances" as offered by Amazon EC2 and "backfill" instances their simplified version which we think may be more useful in a scientific setting. To learn more about this exciting new functionality see our blog.
In addition, we also extended our support for various EC2-compatible features, made improvements to several existing components of Nimbus, and included bugfixes. Simultaneously, we are also releasing a new cloud client #18 with bugfixes and small enhancements. Check out the changelog for full details.
The effort for this release came almost entirely from our open source community. In particular, one of the main contributions (spot instances) was sponsored by Google Summer of Code. We would like to particularly acknowledge the contributions of Paulo Ricardo Motta Gomes, Paul Marshall, Patrick Armstrong, Pierre Riteau and Joe Bester.

Happy New Year! We’ve got some belated fireworks to get it off to a good start—all contained in Nimbus 2.7 RC1 which we are hereby releasing.
The most exciting new functionality is support for spot instances (similar to that offered by Amazon’s EC2) and “backfill” VMs. Both are preemptible instances which run on resources unoccupied by on-demand VMs; an on-demand request may terminate any of those instances in order to acquire resources to run. The main difference between “backfill” and spot instances is that “backfill” preemptible instances are configured and arbitrated by the cloud administrator whereas spot instances are arbitrated by users based on an auction. These features not only give the user an instance with new availability characteristics (“spot” as opposed to on-demand); these instances also allow the administrators to improve the utilization of their clouds.
In addition, we also extended our support for various EC2 features, made improvements to several existing components of Nimbus, and included bugfixes. Check out the changelog for full details.
The effort for this release came almost entirely from our open source community. In particular, one of the main contributions (spot instances) was almost entirely sponsored by Google Summer of Code.

We are happy to announce the Nimbus 2.6 release!
This release introduces three new features. The first one is fast propagation with LANTorrent, a multicast file distribution tool dramatically reducing the time it takes to distribute VM images to nodes. The second new feature is the dynamic node management which allows administrators to add or remove resources from a Nimbus cloud on the fly -- without the need to take the service down. This feature is accompanied by several new upgrade tools that make managing Nimbus clouds easier than ever. Finally, the Nimbus Context Broker got an overhaul -- it received a new HTTP/REST-based interface.
In addition, this release also contains numerous helper programs, small enhancements, and bugfixes. The details can be found in the changelog.
As always, we are indebted to our open source community for their contributions, feedback, and testing. We thank all who volunteered their effort to develop, test, and patch. In particular, we'd like to thank Patrick Armstrong and Pierre Riteau for making this release possible!

We are happy to announce the Nimbus 2.5 release!
This release introduces two major new features. The first one is the Cumulus storage cloud implementation that has been integrated with the Workspace Service but can also be used standalone. Cumulus is compatible with the Amazon Web Services S3 REST API and has a pluggable backend that allows it to support multiple storage systems used by the scientific community. It also includes support for quota management. Cumulus replaces the current GridFTP-based upload and download of VM images. The second new feature is the Zero -> Cloud installation process, which significantly simplifies Nimbus installation and also includes user management tools.
In addition, this release also contains new scheduling and network configuration options, new propagation methods, new workspace pilot options, as well as multiple smaller features and bugfixes -- too many to cover them all in an announcement! The full list is available in the changelog.
The community testing and feedback has been an invaluable help. This has been the most active and productive release cycle that Nimbus has seen and resulted in a product that all of us can be proud of. We would like to thank all who volunteered their effort to help with testing and submitted patches to this release. In particular, we'd like to thank Patrick Armstrong, Colin Leavett-Brown, Paul Marshall, Paulo Motta, Pierre Riteau, Marien Ritzenthaler, and Matt Vliet.

Happy (belated) Independence Day—we have just won independence from a kludgy storage solution and a tyrannical installation system and are happy to announce RC1 of Nimbus 2.5!
This release introduces two major features:
1) Cumulus, a storage cloud implementation that has been integrated with the Workspace Service but can also be used standalone. Cumulus is compatible with the Amazon Web Services S3 REST API, but extends it to include quota management.
2) Zero -> Cloud installation process, which significantly simplifies Nimbus installation and includes user management tools.
In addition, this release also contains new scheduling and network configuration options, new propagation methods, new workspace pilot options, as well as multiple smaller features and bugfixes—too much by far to brag about in this mail; the full list is available in the changelog at: http://www.nimbusproject.org/docs/2.5/changelog.html#2.5
This release would not have been the same without active involvement of the Nimbus open source community. The changelog contains acknowledgements of many members who made substantial contributions: in particular, we’d like to thank Patrick Armstrong, Paulo Motta, Pierre Riteau, and Matt Vliet. They not only contributed new ideas, suggestions, and features but also helped us improve code quality—priceless!

Nimbus is to be featured in a demo at this week's OGF29 in Chicago. The demo involves six Nimbus cloud installations spread across FutureGrid and Grid'5000. Many VMs with up to 1000 cores will be started between the clouds and used to run a single bioinformatics application (BLAST). The demo will also showcase some experimental features in Nimbus for fast propagation of VM images.
From the OGF29 site:
Sky Computing on FutureGrid and Grid'5000
"Sky computing" is an emerging computing model where resources from multiple cloud providers are leveraged to create large scale distributed infrastructures. This demonstration will show how sky computing resources can be used as a platform for the execution of a bioinformatics application (BLAST). The application will be dynamically scaled out with new resources as need arises. This demonstration will also show how resources across two experimental projects: the FutureGrid experimental testbed in the United States and the Grid'5000, an infrastructure for large scale parallel and distributed computing research in France, can be combined and used to support large scale, distributed experiments. The demo will showcase not only the capabilities of the experimental platforms, but also their emerging collaboration. Finally, the demo will showcase several open source technologies. Specifically, our demo will use Nimbus for cloud management, offering virtual machine provisioning and contextualization services, ViNe to enable all-to-all communication among multiple clouds, and Hadoop for parallel fault-tolerant execution of BLAST. (POC: Kate Keahey, Mauricio Tsugawa, ANL; Pierre Riteau, IRISA)

Computing Techniques Seminar
Thursday, January 29, 2pm. Feynman Computing Center, Fermilab.
Abstract:
Infrastructure-as-a-Service (IaaS) cloud computing is emerging as a viable alternative to the acquisition and management of physical resources. But what exactly is cloud computing and to what extent can it be used to meet the needs of scientific applications?
In this talk, I will give an overview of cloud computing and describe Nimbus -- a toolkit that provides an open source, EC2-compatible IaaS implementation as well as tools that enable, for example, the creation of tightly-coupled clusters such as are often used in science.
I will describe how applications drove the development of various Nimbus capabilities and how they use these capabilities today on Amazon EC2 and the Science Clouds. Finally, I will discuss the emerging trends in cloud computing and discuss how they can benefit science.

There will be a Virtual Workspaces tutorial at the Open Source Grid Cluster conference in Oakland, CA. The conference is May 12-16, 2008. The Virtualization and Cloud Computing with Globus session is on Wednesday, May 14th, from 4:30-6:00 pm. We hope to see you there!
Quoting from the summary:
One of the primary obstacles users face in grid computing is that Grids provide access to many diverse resources, their applications often require a very specific, customized environment. This disconnect can lead to resource underutilization, user frustration, and much wasted effort spent on bridging the gap between applications and resources. Virtual Workspaces describe the environment required for the execution of an application that can be dynamically deployed across a variety of resources creating a working and consistent platform for grid applications.
This tutorial will introduce the Globus Toolkit workspace service that implements workspaces as Xen virtual machines and enables authorized grid clients to dynamically deploy them and manage their resources. Further, we will describe and demonstrate the workspace "cloudkit" that provides a user-friendly interface on top of the workspace service allowing authorized users to easily provision and run VMs on the available community clouds. Finally, we will describe how the process of contextualization can be used to provide on-demand functioning clusters and give examples of its use by applications.
