Infrastructure as a Service (IaaS) is a cloud computing model that provides virtualized computing resources over the internet. With IaaS, users can rent virtualized hardware resources such as servers, storage, and networking components from a cloud service provider on a pay-as-you-go basis. This allows organizations to scale their infrastructure up or down based on demand without the need for physical hardware investment and maintenance.

Cloud migration services involve the process of moving digital assets, such as applications, data, and IT infrastructure, from on-premises environments to cloud-based platforms. This migration can also involve transferring assets from one cloud provider to another or re-architecting applications to better leverage cloud-native features and capabilities. Cloud migration services typically include assessment, planning, execution, and optimization phases to ensure a smooth and successful transition to the cloud.
