Existing LAMP stack servers are under utilized
VM or Physical servers
Maximize returns from existing server resources
Do not want to provision new VM
Could not provide dedicated LAMP stack per tenant
Tenant owners cannot start or stop services (Web server, MySQL)
No dynamic load balancing of resources per tenant
SLA based CPU, Memory and DISK IO allocation
Do not want to disturb existing installation
ZERO downtime cannot afford to bring down existing services
