Similar to physical and data center networks, cloud networks have their own structure and components, such as the following:
- Software-Defined Networking (SDN): SDN replaces traditional network architectures by implementing networks on demand by using popular SDN transport and encapsulation protocols
- Security groups: Flexible and programmable firewall filters that allow traffic control at scale, avoiding a single point of failure
- NAT gateways: To efficiently route traffic in and out of the cloud network, providing NAT services when necessary
- Load balancers: To load balance the incoming traffic between groups of application servers
