Guided Project – Update and maintain resources

Microsoft Azure Admins update subnets and secure VMs to support new FTP infrastructure, adding a dedicated subnet and NSG rules. The project involves configuring network security groups to restrict traffic to port 22 for SFTP.

Why This Matters

Ideal cloud models assume static infrastructure, but real-world scenarios demand dynamic adjustments. Misconfigured Azure subnets or security groups can lead to security breaches or service outages, with costs rising sharply for unmonitored resources. For example, a misconfigured NSG might expose sensitive VMs to the internet, risking data leaks.

Key Insights

• “Subnet creation and NSG configuration for FTP traffic in Azure”: The project adds an ftpSubnet and associates it with a network security group (NSG) allowing only port 22 traffic.
• “Sagas over ACID for e-commerce”: Not directly applicable, but similar principles apply when managing distributed Azure resources—ensuring consistency across subnets, VMs, and storage.
• “Temporal used by Stripe, Coinbase”: Not relevant here, but Azure’s automation tools (e.g., auto-shutdown) serve similar purposes for operational reliability.

Practical Applications

• Use Case: Azure Admins configuring subnets and NSGs for secure FTP servers.
• Pitfall: Overlooking subnet isolation, leading to cross-VM traffic vulnerabilities.
