Finally, virtualization even abstracts away this commodity hardware such that only a computing substrate, an abstract platform for performing computations, is left. -System administrators and operators no longer need to decide on which specific machine an application will run and worry about if there will be enough resources available. +System administrators no longer need to decide on which specific machine an application will run and worry about if there will be enough resources available. This is the promise of ``the cloud'': full elasticity of computing resources. -In the cloud, one can dynamically request the amount of resources, unlike buying a fixed amount of physical servers, and only needs to pay for the exactly these resources. +In the cloud, one can dynamically request the amount of resources, unlike buying a fixed amount of physical servers, and only needs to pay for exactly these resources. Currently, the most widely used platform that provides such a computing substrate is Kubernetes. This is evident by the fact that all major public cloud platforms offer a managed Kubernetes service (AWS EKS, GCP GKE, Azure AKS, IBM Cloud Kubernetes, AlibabaCloud ACK).
