Generate. Service Quotas is a service for viewing and managing your quotas easily and at scale as your AWS workloads grow. Quotas, also referred to as limits, are the maximum number of resources that you can create in an AWS account. What Are Resource Quotas in. Resource quotas are a tool for administrators to address this concern. A resource quota, defined by a ResourceQuota object, provides constraints that limit aggregate resource consumption per namespace. A ResourceQuota can also limit the quantity of objects that can be created in a namespace by API. Disk quotas allow Windows administrators to control and limit the amount of disk space that users use on the file systems of servers and workstations. Windows Server supports two types of disk quotas: File Server Resource Manager quotas and NTFS quotas. [PDF]
