Infrastructure-as-a-Service (IaaS) means providing compute, storage and networking functions to customers in the form of a service, a main benefit being that those customers need no infrastructure (datacenter, server room) of their own. Amazon Web Services (AWS) is the leading IaaS provider. Private cloud platforms like Eucalyptus also belong to the IaaS category because they allow you to create your own IaaS cloud on your own servers.
Software-defined datacenter (SDDC) is about the way you architect your datacenter/infrastructure. Your datacenter can be said to be software-defined when the hardware resources have been virtualized and there is a dynamic way of configuring the datacenter and of provisioning compute cycles as a service.
In summary, IaaS is about the way compute power is provisioned, SDDC about how it is architected. It could be argued that in order to provide infrastructure as a service, your datacenter needs to be software-defined. Vendors try to promote their own terminology, so you will see different definitions by different companies.I read an interesting article https://diceus.com/cloud-mania-undeniable-benefits-iaas/ on this topic, leave it here, can someone help you in the future
