Consider the following simplified description of deployment with hardware and software load balancing and clusters. Construct a deployment diagram for the system. "A network load balancer is an appliance device that is used to split network load across multiple servers. A jetNEXUS ALB-X hardware load balancer combines the functions of OSI Layer 7 (Application Layer) load balancing, HTTP compression, SSL offload and content caching in one solution. It has 2 active hardware load balancers connected to 2 to 4 Sun Fire Servers. Each server has 3 instances of IBM WebSphere 7 J2EE application servers installed, so we have both vertical and horizontal clustering. When database connection is requested by application, Oracle run-time connection load balancing selects connection that belongs to the best instance from the connection cache provided by Oracle RAC (Real Application Clusters) database."
