Most EJB servers show high degree of availability. Server clusters are an example of how this is functionality is achieved. What key advantages might server clusters offer in an EJB environment?

Server clusters provide high availability and scalability in EJB environments by distributing incoming requests across multiple servers. This load distribution prevents any single server from becoming a bottleneck and allows the system to continue functioning even if one server fails. The load balancing capability ensures optimal resource utilization and improved performance. Location transparency, caching, and 2PC are separate concepts not directly related to clustering benefits.
