11 Top Open-source Resources for Cloud Computing
 Open-source software has  been on the rise at many businesses during the extended economic downturn,  and one of the areas where it is starting to offer companies a lot of  flexibility and cost savings is in cloud computing. Cloud deployments can save  money, free businesses from vendor lock-ins that could really sting over time,  and offer flexible ways to combine public and private applications. The  following are 11 top open-source cloud applications, services, educational  resources, support options, general items of interest, and more.

 Eucalyptus. Ostatic broke  the news about UC Santa Barbara's open-source cloud project last year.  Released as an open-source (under a FreeBSD-style license) infrastructure for  cloud computing on clusters that duplicates the functionality of Amazon's EC2,  Eucalyptus directly uses the Amazon command-line tools. Startup Eucalyptus  Systems was launched this year with venture funding, and the staff includes  original architects from the Eucalyptus project. The company recently released  its first major update to the software framework, which is also powering the cloud  computing features in the new version of Ubuntu Linux.

 Red Hat's Cloud. Linux-focused open-source player Red Hat  has been rapidly expanding its focus on cloud computing. At the end of July, Red  Hat held its Open Source Cloud Computing Forum, which included a large number of  presentations from movers and shakers focused on open-source cloud initiatives.  You can find  free webcasts for all the presentations here. The speakers include Rich  Wolski (CTO of Eucalyptus Systems), Brian Stevens (CTO of Red Hat), and Mike  Olson (CEO of Cloudera). Stevens' webcast can bring you up to speed on Red Hat's  cloud strategy. Novell is also an open source-focused company that is  increasingly focused on cloud computing, and you can read about its strategy here.

 Traffic Server. Yahoo this week moved its open-source cloud  computing initiatives up a notch with the donation of its Traffic  Server product to the Apache Software Foundation. Traffic Server is used  in-house at Yahoo to manage its own traffic, and it enables session management,  authentication, configuration management, load balancing, and routing for entire  cloud computing software stacks. Acting as an overlay to raw cloud computing  services, Traffic Server allows IT administrators to allocate resources,  including handling thousands of virtualized services concurrently.

 Cloudera. The  open-source Hadoop software framework is increasingly used  in cloud computing deployments due to its flexibility with cluster-based,  data-intensive queries and other tasks. It's overseen by the Apache Software  Foundation, and Yahoo has its  own time-tested Hadoop distribution. Cloudera is a promising startup focused on  providing commercial support for Hadoop. You can read much  more about Cloudera here.

 Puppet. Virtual servers are on the rise in cloud  computing deployments, and Reductive Labs' open-source software, built upon the  legacy of the Cfengine system, is hugely  respected by many system administrators for managing them. You can use it to  manage large numbers of systems or virtual machines through automated routines,  without having to do a lot of complex scripting.

 Enomaly. The  company's Elastic Computing Platform (ECP) has its roots in widely used  Enomalism open-source provisioning and management software, designed  to take much of the complexity out of starting a cloud infrastructure. ECP  is a programmable virtual cloud computing infrastructure for small, medium and  large businesses, and you can read much more about  it here.

 Zoho. Many people use Zoho's huge suite of free,  online applications, which is competitive with Google Docs. What lots of folks  don't realize, though, is that Zoho's core is completely open source — a shining  example of how SaaS solutions can work in harmony with open source. You can find  many details on how Zoho deploys open-source tools in  this interview.

 OpenNebula. The  OpenNebula VM Manager is a core component of Reservoir. It's an open-source  answer to the many virtual machine management offerings from proprietary  players, and interfaces easily with cloud infrastructure tools and services.  "OpenNebula is an open-source virtual infrastructure engine that enables the  dynamic deployment and re-placement of virtual machines on a pool of physical  resources," according to project leads.

It's good to see open-source tools and resources competing in the cloud computing space. The end result should be more flexibility for organizations that want to customize their approaches. Open-source cloud offerings also have the potential to keep pricing for all competitive services on a level playing field.
