-Azure NAT Gateway is the recommended method for outbound connectivity. Azure NAT Gateway is a fully managed and highly resilient Network Address Translation (NAT) service. A NAT gateway doesn't have the same limitations of SNAT port exhaustion as default outbound access. A NAT gateway replaces the need for a virtual machine to have a public IP address to have outbound connectivity.
