In our third installment of the Cloud Possible Series we discuss Infrastructure as a Service (IaaS), one of three types of cloud deployment models. Here we discuss the requirements of the Utility and the benefits that this model provides.
For Utilities who have the greatest requirement for flexibility and control, the IaaS operating model is the best choice. This model is closest to a dedicated on-premise computing environment. Utilities who choose an IaaS model to receive a scalable infrastructure, with the ability to grow compute, storage, and network on demand. In addition to infrastructure, IaaS providers often offer a variety of additional services: firewalls, load balancers, IP addresses, VLANs, data protection/backups, encryption, colocation, cross-connects, and internet connections.
