Implementing Azure Firewall
Azure Firewall is a perimeter network security service in Azure. It can be used to inspect both incoming and outgoing virtual network connections to keep workloads safe from malicious traffic. Unlike a third-party firewall appliance that is deployed as a Network Virtual Appliance (NVA) in Azure, Azure Firewall is a managed service, meaning we don’t have to worry about maintaining its underlying operating system, updating its services, implementing high availability, or scaling it, as all these tasks are taken care of by Microsoft. All we need to do is deploy the service, configure it, use it, and pay for usage!
