There is more than one reason why enterprises are eyeing software-as-a service models these days. Deployment, integration and security are just three headaches that can be pushed off IT's plate when it comes to new applications and dealing with increasing application management. The big impetus, though, is that managed service providers are pushing on-demand, real-time application delivery as it's saving them time, money and labor as well.
