Create a single View of all your tenants subscriptions - easily identify Azure Credit availability

One Azure Dashboard for all Subscriptions in Your Azure Tenant

A production subscription. A development environment. A Microsoft for Startups sponsorship. Perhaps a Visual Studio subscription, a trial subscription, or a subscription dedicated to experimentation.

The information you need is scattered across Azure:

💰 Cost Management for spend
📦 Resource Graph for inventory
💳 Billing for credits and subscriptions
🔍 Individual subscription pages for everything else

I wanted a single place to answer three simple questions:

✅ What is running?
✅ What is it costing?
✅ How much Azure credit is left?

This solution creates an Azure Portal dashboard covering every subscription in a tenant.  Barclays Eagle Labs is amazing for startups, and they have helped me immensely, including getting Microsoft Startup Credits, and I think this will help a lot of people with their Startups.

What the dashboard shows

• Monthly cost per subscription
• Resource counts by subscription
• Resources grouped by type
• Complete resource inventory across all subscriptions
• Subscription offer type (Pay-As-You-Go, Sponsorship, Visual Studio, etc.)
• Billing account details
• Remaining Azure credit and expiry dates where available
• Direct links into Subscription Overview and Cost Analysis

Deployment in Four steps

1. Download the file:

• New-SubscriptionsDashboard.ps1

2. Open Azure Cloud Shell and select PowerShell

3. Upload the New-SubscriptionsDashboard.ps1 file into your Cloud Shell home directory

4. Get your tenant ID, set the dashboard location and run the creation PowerShell script:

PS> $tenant = (az account show --query tenantId -o tsv)

PS> $region = "uksouth"   // Set your region for the new dashboard

PS> ./New-SubscriptionsDashboard.ps1 -Tenant $tenant -Location $region

5. Open the dashboard URL returned by the deployment.

Why I like this approach

The dashboard continuously updates resource inventory, resource counts and subscription costs using Azure Resource Graph and Cost Management, while also providing a snapshot of credit balances and billing information.

For organisations using multiple subscriptions, especially Azure Sponsorship or Microsoft for Startups credits, this gives a genuine single pane of glass across the entire tenant. No more jumping between Cost Management, Billing, Resource Graph and Subscription Overview pages. One dashboard. One view.

Introduction to EULYNX

Current position: Signalling has traditionally been set at the national level, which is hard to integrate when trains cross borders. It is expensive and harder to make interoperable. 

• EULYNX is the digitalisation of the railway signalling industry.  
• The aim is to create open, standardised interfaces between signalling system components.
• Modular approach to signalling, offering standard interfaces for interaction. 
• Reduces vendor lock-in and allows for modular replacement.
• EULYNX publish documents on the architecture and interface specifications.
• Covers architecture, components and interfaces.

EULYNX specifications cover the following subsystems:

1. Signals & Object Controllers (SCI LS) 
2. Points and point machines (SCI-P), Points and Switches
3. Axle counters and train detection (SCI TDS), train block vacancy
4. Level crossings (SCI LC/LX)
5. IP-based communications (including RaSTA) (SCI IO) Interfaces
6. Cybersecurity and networking interfaces (Core)
7. Maintenance and Data Mgmt (MDM) (Core)
8. Electronic Interlocking (Core)

Adjacent EULYNX systems communicate with:

1. Radio Block Centre (SCI RBC),
2. Traffic Management (SCI CC),
3. Adjacent Interlocking (SCI ILS).

15 key partners are: DB InfraGO (Germany), Network Rail/GBR (UK), SNCF (France), RFI (Rete Ferroviaria Italiana), ÖBB (Austria), ProRail (Netherlands), Infrabel(Belgium), Croatia, Czech Republic, Finland, Luxembourg, Norway, Slovenia, Sweden, and Switzerland.
