Azure Landing Zone Accelerators are architectural guidance, reference architecture, reference implementations and automation packaged to deploy workload platforms on Azure at Scale and aligned with industry proven practices.
Azure Spring apps Landing Zone Accelerator represents the strategic design path and target technical state for an Azure Spring Apps Service deployment.
This repository provides packaged guidance for customer scenarios, reference architecture, reference implementation, tooling, design area guidance, sample spring apps deployed after provisioning the infrastructure using the accelerator. The architectural approach can be used as design guidance for greenfield implementation and as an assessment for brownfield customers already using Spring boot apps.
The enterprise architecture is broken down into key design areas, where you can find the links to each at:
| Design Area | Considerations and Recommendations |
|---|---|
| Identity and Access Management | Design Considerations and Recommendations |
| Network Topology and Connectivity | Design Considerations and Recommendations |
| Management and Monitoring | Design Considerations and Recommendations |
| Security, Governance, and Compliance | Design Considerations and Recommendations |
This repository contains instructions for creating an Azure Spring Apps reference architecture that can be used for deploying Spring Boot applications in a typical enterprise landing zone design. It uses a hub and spoke architecture with a single spoke. East/West traffic (traffic between resources in the hub and resources in the spoke) is filtered with Network Security Groups and North/South traffic (traffic between the Internet and resources in the hub or spoke) is routed through and mediated with an instance of Azure Firewall.
- Azure Spring Apps is deployed using vnet-injection to allow for mediation inbound and outbound traffic to the Azure Spring Apps Instance and deployed applications.
- The Azure Firewall instance has been configured to write its logs to a Log Analytics Workspace. You can leverage these Kusto queries to analyze Azure Firewall log data written to Log Analytics.
- Hub and Spoke Virtual Networks are configured to use Azure Firewall for DNS queries utilizing the DNS Proxy feature of Azure Firewall.
- Azure Private DNS zones for Azure Spring Apps and support services deployed with Private Endpoints
- A single Windows Server 2022 Virtual Machine the hub Virtual Network for testing access to applications deployed into the Azure Spring Apps instance. This virtual machine is configured with the Microsoft Monitoring Agent and is integrated with the Log Analytics Workspace. This VM is not exposed to the internet and is only accessible via Azure Bastion (for brevity, both the VM and Azure Bastion are not shown in the diagram).
- Log Analytics Workspace where Azure Spring Apps, Azure Firewall, and the virtual machine deliver logs and metrics.
- Instance of Azure Key Vault deployed with a Private Endpoint for secrets and certificates storage for applications deployed to Azure Spring Apps
- Instance of Azure Bastion for connection to the Windows Server 2022 virtual machine running in the hub virtual network.
For Azure Spring Apps Standard SKU:
- Instance of Azure Database for MySQL flexible server deployed with VNET Integration. This can be used to deploy the PetClinic sample app described in this document.
For Azure Spring Apps Enterprise SKU:
- Instance of Azure Database for PostgreSQL flexible server deployed with VNET Integration and Azure Cache for Redis with Private endpoint.
Pick the below scenario to get started on a reference implementation.
