7 Introduction General facts The ALOHA is a solution dedicated to application platforms (Web, filtering relay, directories, CRM, ERP, thin client servers, ) high availaibility and load balancing. Proposed as an appliance, it is partly based on the L7 open source load balancer HA Proxy and L4 LVS (Linux Virtual Server) both known for their liability and performance. These two software are mainly used all over the world in high performance and heavy constraints production environments. The ALOHA includes an enriched and optimised HA Proxy running on top of a dedicated linux embedded operating system. 7

8 Introduction Definition What is load balancing? Although one server power is always limited, a Web application should run on many servers to support a constant growth of the number of users. This is what is called application scalability. For intranet applications, scalability management is quite easy because the number of users is already known and will rarely grow suddenly. On the other hand, for Internet portals or e-commerce applications, the regular growth of the number of users as the constant growth of high bandwidth links are both heavy loading factors. In this case, IT managers need to find solutions to achieve scalability by balancing the load amongst many servers, by using internal applications processes or/and by platform architecture reorganization. Load balacing allows to use many servers that will then provide the same services and will all do the same job (although it is possible to dedicate some servers to specific as we will see later). But, increasing the number of servers may also increase the risk of failure in the platform. This risk must be seriously addressed. Ability to guarantee the service availability is calles high availability. This feature is frequently required in a load balacing environment which is the main reason why most of the people are mixing these two concepts together. 8
