Cfengine for Enterprise Configuration Management
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

If you have a lot of hardware, go for Puppet
But, if you are concerned with resource consumption, Cfengine is the right choice. A recent report shows that Cfengine is up to 40 times more effective than Puppet (http://www.usenix.org/publications/login/2010-02/pdfs/bjorgeengen.pdf. - Requires login). Follow the discussion on Puppet's group here.
a (possibly better) alternative
cfEngine is cool, and might have been the first centralized configuration system with such vast reach. However, I must suggest readers also look into Puppet by Reductive Labs. It was covered last year by Linux Journal and continues to have very rapid development and an excellent support community.
I maintain a Puppeted environment, and have had nothing but good experiences with it.
Cheers,

Scale
Is your environment large?
The reason Cfengine was the only viable alternative of the two for me was the Ruby overhead.
We don't have the resources to maintain a fully fledged Ruby installation (with web servers) on *every* machine just to have Puppet installed.
Remember that Ruby also requires updates and maintenance.
