The document discusses reimagining the datacenter through software defined infrastructure. This allows datacenters to become more dynamic, automated and efficient by treating compute, storage and networking resources as composable blocks that can be allocated on demand. This approach breaks down traditional silos and allows simpler deployment and maintenance while improving agility, automation and efficiency. The software defined approach is compared to the traditional rigid infrastructure model and examples are given of how it can improve provisioning times, utilization rates and flexibility.
