A tenant-based resource allocation model for scaling Software-as-a-Service applications over cloud computing infrastructures

► Overutilization occurs when resource utilization gets above the point of exhaustion. ► Underutilization is the amount of resources that can be allocated within other VMs. ► Tenant-based isolation is achieved through authentication and persistence layers. ► Tenant-based allocation determines the minimum number of VM instances for workload. ► Load balancer distributes requests based on tenant context and VM availability.
