Load Balancing cluster

Unity is strength!

Cluster technology can be exploited for the supply of network services characterized by high performances and high reliability, thanks to the opportunity of sharing the work load on several computers.

Open-source software, which has reached quality and availability standards such as to be used in professional activities with high levels of reliability, productivity and reduction in prices, offers solutions for load balancing thanks to the LVS project.

Aethia systems for load balancing are servers characterized by high performances, scalability and reliability, are based on server clusters which use LVS load balancing system. The architecture of the server cluster is fully transparent to end users, who interact with a single high performance virtual server.

This load balancing solution can be used to build highly scalable and highly available network services, such as web, cache, mail, ftp, media and VoIP services.

Advantages

High performances, provided by the high level of computation power attainable by the use of parallel computing and by the best available hardware technologies.
High reliability, assured by the presence of different computers working on fault-tolerance and by the opportunity of redounding the main server.
Turnkey solution, thanks to the transparency of network service balancing software, which enables the user to work as it was a normal server.
Reduction in prices, thanks to the excellent price/performance ratio offered by Linux clusters technology, by the choice of carefully selected hardware products and by the use of open-source software without licence fees.
Scalability, thanks to the opportunity of easly and uninterruptedly add new nodes, modulating their number in proportion to the work load.
Flexibility, thanks to the high level of customization that open-source softwares enable by their large package and source availability.
Aid and support: from a hardware point of view with aid solutions which can be extended and customized (two years on-center base) and from a software point of view thanks to our qualified experts' experience; whenever it's possible, times and expenses are minimized by remote interventions.
