I will explore a real-world example in the logistics domain of how we built a robust and scalable integration architecture using .NET Core, Azure, EventStoreDB, and Power Platform. I will discuss how we addressed the challenges of integrating multiple data sources, including third-party systems through event-driven architecture, and also provide insights into using persistent subscriptions for event projections and efficient data synchronization between Dataverse and CosmosDB.

help businesses manage their fleets of vehicles,
from cars and trucks to vans and trailers to
improve their operational efficiency, reduce
costs, and improve customer service
Fleet Management Systems

7. Problems
An outdated monolithic solution
struggles with support, scalability,
feature development, and critical
security vulnerabilities fixes
Route planning issues arise due to
the lack of near real-time fleet
GPS data
The absence of a mobile app and
limited access for suppliers and
logisticians hinder seamless user
experience and efficient
collaboration
Lacks integration capabilities for
3rd party GPS tracking systems
and does not provide a Public API
for external connections
Legacy System Routes Planning Communication
Inefficient communication from
inconsistent email formats and
reliance on multiple channels,
such as phone calls, SMS,
WhatsApp, Telegram, and Viber,
causing delays and confusion
Connectivity Integrations

8. Challenges
Migrate liveness production data
from multiple data sources to
diverse target databases
Requires specific solutions
tailored to their processes, flows,
data, reports, etc.
GPS tracking and route
optimization to enable location
monitoring as well as speed and
fuel usage, and efficient route
planning
Provide external Public API by subscription
model to the customers
Data Migration No/Low Code SaaS CRM
Multitenant SaaS CRM for logistics
industry covering FMS, TMS,
custom GPS services and access
to external data by subscription

FMS TMS
Fleet Management Systems
(FMS) streamline and optimize
fleet operations by providing
centralized control, data
analysis, and communication
tools
Transportation Management
Systems (TMS) facilitate the
planning, execution, and
optimization of shipping and
logistics processes across
multiple transportation modes
Third-party offerings or
solutions provided by external
systems or companies, not in-
house
3RD Party Services

11. Database Solutions
EventStoreDB Dataverse
EventStoreDB is a specialized
event-based database designed
for event sourcing and event-
driven architectures
Dataverse is a fully managed,
multi-tenant, cloud-based
service for storing and managing
business data within the
Microsoft ecosystem
Cosmos DB is a globally
distributed, multi-model NoSQL
database service that supports
various data models, offering
automatic scaling and global
distribution on Microsoft Azure
