What does using a service-focused approach provide to managing the storage infrastructure?

Using a service-focused approach allows the storage infrastructure to be managed based on the needs of the business or customers. This approach focuses on the delivery of services, rather than just the management of storage components or devices. When a service provisioning request is received, the service-focused approach provides a framework to determine the appropriate workflow to fulfill that request. This may include provisioning additional storage resources, modifying existing configurations, or other tasks to meet the service level agreements (SLAs) of the business or customer.
