Network Overview

The Network tab reveals connectivity, dependencies and traffic patterns across the estate, giving you the context you need before grouping applications into waves. It gives an estate-level view of which applications are most connected, which are exposed to the internet, and where risky ports are in use, then lets you drill into any single application's detailed dependency flows.

Headline tiles¶

Four tiles summarise network activity and risk at a glance: Total Connections (the overall volume of analysed network flows across the estate), High Dependency Apps (applications heavily entangled with the rest of the estate), Internet-Facing Applications (those with external exposure) and Potential Risk Ports (open ports that warrant review). Together they tell you where connectivity will most influence sequencing and security decisions.

Network Lens¶

The Network Lens re-frames the estate view around a particular concern:

• All Applications: the full picture, nothing filtered.
• Cross-Env Traffic: applications talking across environment boundaries.
• Internet Facing: applications with external connectivity.
• Port Risk: applications using ports flagged as potentially risky.
• Insights: a summary view showing Total Connections, Risky Ports, External Connections and Cross-Environment Traffic panels, plus a banner recommending connecting Dr Migrate to a real-time dependency data source for richer flow data.

Applications by Network Gravity¶

The central table ranks applications by network gravity (how much they pull on the rest of the estate), so you can see at a glance which applications anchor a wave and which can move freely. Its columns:

This is an estate-level view: it ranks and compares applications so you can prioritise. When you click Analyze, you drop into that application's detailed dependency flows inside the Application Drawer's Networking tab, where the interactive dependency graph, flow tabs and per-connection detail live.

Why the roll-up matters¶

Raw network data is overwhelming: a mid-sized estate can have hundreds of thousands of server-to-server flows. Dr Migrate applies an intelligent roll-up that summarises those flows at the application level, and dynamic filtering that lets you expand only the detail you need. That's what makes dependencies actually usable for planning: you can reason about how applications relate, then drill down to the exact server-to-server connections (and export them, for example as firewall rules) only when you need them.

Where to go next¶

To examine a single application's connectivity in depth, open it in the Application Portfolio and use its Networking tab. To turn dependencies into a sequenced plan, move to Plan → Migration Planning.
