The developers at Generation D have launched High Availability ASTerisk (HAAST), a software application that allows customers to create cost-effective Asterisk clusters using any pair of off-the-shelf Linux boxes. HAAST is a software application that creates a high-availability, clustered group of Asterisk servers that act as a single server. It can detect a range of failures on any single Asterisk server and automatically transfer control to its mate, resulting in a telephony environment with minimal down time. Key features include rapid failover (as low as seven seconds), detailed logging, Web interface, extendable API, intuitive installation and the ability to leverage low-cost hardware yet achieve a high-availability solution.
The raison d'être of Gluster's new VMStor is to simplify scalable NAS for virtual machine storage. Gluster's strategy is eliminating the requirement to use a traditional storage area network (SAN) based environment, which can be expensive to scale. Initially supporting VMware, Gluster VMStor scales to multiple petabytes and can store an unlimited number of VM images. Key capabilities, such as VM-level snapshots and backup, can be performed with a single mouse click or automated with existing tools and cloud management software. Other features include integration with VMware UI and utilization of standard NFS filesystem architecture.
Vyatta calls the new 6.1 release of Vyatta Network OS a “jump forward” due to advances in IPv6 interoperability, cloud-specific features and enhanced enterprise security. Vyatta version 6.1 has received IPv6 Ready Logo Phase 2 certification, verifying the implementation of IPv6 core routing protocols. For cloud providers and enterprises moving applications or servers to the cloud, Layer 2 cloud bridging allows physically separate networks to communicate with each other over the Internet securely, as if they were on a single Ethernet network. Regarding security enhancements, Vyatta also has added stateful firewall failover and enhanced intrusion prevention services through a partnership with Sourcefire. The upshot, says Vyatta, is that the Vyatta Network OS makes it “even easier for large, distributed organizations to connect, protect and secure physical, virtual and cloud computing environments.”

Practical Task Scheduling Deployment
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
