Cloud providers offer most of the traditional networking functionality that you would find in a data center. The difference is that in the cloud, the networking functions provided by traditional firewalls, routers, switches, and load balancers are implemented in the provider's proprietary software. The upside of this approach is that it allows the provider to achieve high availability for these core networking functions.

In the IaaS model, cloud providers also offer Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), and virtual private cloud networks as part of the service, so you don't have to spin up your own DNS or DHCP servers as you would in a data center environment.
