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.”
