484 WebSphere and .NET Coexistence
Availability in .NET is mainly handled by Windows Server Clustering which we
covered in “Windows Server 2003 Clustering” on page 475 and also “Network
Load Balancing” on page 477.
Clustering is important because if one server goes down, the application is able
to failover from one server to another. To avoid a single point of failure, a cluster
should be considered for front-end (such as Web servers) and back-end servers
(such as database servers). Besides clustering, Network Load Balancing is also
important for high availability since it redirects the incoming network traffic to
working cluster hosts if a host fails or is offline.
To guarantee availabilty of a .NET application, it is necessary to have redunda ...
