A server is hardware used to run an organization’s services. When managed on-premises, it may sit in an office or a remote data center. Either location needs power, cooling, and a network connection. section 8.3.2
Capacity takes planning: servers must be bought, delivered, provisioned, and installed, which can take weeks. Buying too much leaves hardware unused; buying too little strains hardware and staff during busy periods. section 8.3.2
Handling a promotion
