Does PaaS Get Rid Of Ops? In the past, Infrastructure-as-a-Service (IaaS) was the real king of the hill. Clouds were created with cost reduction and rapid deployment in mind. For instance, companies that needed servers no longer needed to worry about red tape or even system administration. All it took was signing up for a new account, and within a few clicks a hardware profile with the OS image needed would be available and ready to use. This kind of setup was perfect, provided that your needs were generic and could match the OS images that the cloud provider gave.
