Microsoft's recent announcement of its upcoming Azure Gateway Load Balancer is great news for organizations requiring rapidly scalable firewalls with high availability in public cloud. Cisco has partnered with Microsoft and will be supporting Cisco Secure Firewall with Azure Gateway Load Balancer. The Gateway Load Balancer makes rapid scaling of security services with highly available protection simpler than ever. It's part of how Cisco is helping to harmonize security across your public and hybrid cloud environments.
The Azure Gateway Load Balancer provides bump-in-the-wire functionality, ensuring Internet traffic to and from an Azure VM, such as an application server, is inspected by Secure Firewall, without requiring any routing changes. This is another example of how Secure Firewall drives efficiency at scale. Additionally, the integration simplifies deployment, managing, and scaling of your firewalling. This reduces operational complexity, providing a single entry and exit point for traffic at the firewall. With the gateway load balancer, your applications and infrastructure maintain visibility of source IP address, which is critical in some environments.
