Brooke Steele engineered robust Azure networking and security automation for the Azure/missionlz repository, delivering modular infrastructure-as-code solutions using Bicep and PowerShell. Over seven months, Brooke built and enhanced features such as VPN and NAT Gateway deployments, modular firewall rules, and automated Azure Policy management, all designed for repeatability, governance, and secure hybrid connectivity. By refactoring network components and enforcing centralized firewall inspection, Brooke improved both operational reliability and security posture. The work emphasized modularity, parameterization, and documentation, enabling scalable, auditable deployments across environments. Brooke’s contributions demonstrated depth in Azure networking, Infrastructure as Code, and DevOps automation, supporting maintainable cloud architectures.

October 2025 monthly summary for Azure/missionlz: Delivered a security-focused network enhancement by enforcing forced tunneling via the Azure Firewall for the Virtual Network Gateway add-on, ensuring all hub, spoke, and on-prem traffic passes through firewall for centralized policy enforcement. Removed routingMode abstraction and updated architecture/docs to reflect the new firewall-centric traffic flow. This change strengthens security posture, improves governance, and provides clearer guidance for ops and onboarding across the multi-site environment.

Month: 2025-08 — Delivered two infrastructure-as-code add-ons for the Azure Mission Landing Zone, enhancing connectivity and outbound scalability while improving IaC quality and documentation. Key features delivered: - Virtual Network Gateway add-on for Mission Landing Zone hub enabling Site-to-Site VPN connectivity, routing traffic through the Azure Firewall, and updating VNet peerings to support gateway connectivity from spoke VNets; includes GatewaySubnet creation/update, a dedicated VPN gateway route table, and provisioning of Virtual Network Gateway and Local Network Gateway resources. - Azure NAT Gateway add-on for Mission Landing Zone introducing NAT Gateway deployment attached to the AzureFirewallSubnet with a Public IP Prefix for stable outbound egress; includes documentation and Bicep code to deploy and configure the NAT Gateway, offloading NAT from the Azure Firewall. Major bugs fixed: - No major defects closed in this period; work focused on feature delivery and IaC improvements. Overall impact and accomplishments: - Strengthened secure connectivity between hub-spoke networks with Site-to-Site VPN and updated routing; improved outbound scalability and resilience by offloading NAT from the Azure Firewall. - Accelerated deployment and consistency through Infrastructure as Code (Bicep) with clear documentation, reducing manual steps and enabling repeatable environments. - Improved maintainability via resource-name fixes and better naming consistency in gateway add-on components. Technologies/skills demonstrated: - Azure networking (Site-to-Site VPN, GatewaySubnet, VNet peering, Azure Firewall routing) - NAT Gateway and outbound SNAT scaling - Infrastructure as Code with Bicep - Documentation and onboarding for new add-ons
