At the 18th EATEL Summer School on Technology-Enhanced Learning (JTELSS 2024) in Gabicce Mare, Pesaro, Italy, Gianluca Romano and Sebastian Gombert conducted the workshop “From Learner Behavior to Big Data: How to Implement and Scale Learning Analytics Infrastructures in the Cloud”.

In the ever-evolving world of cloud computing, Azure stands out as a robust platform offering a myriad of services and tools to help businesses innovate and scale. Recently, we had the chance to delve deep into Azure’s ecosystem, exploring its billing structures, infrastructure capabilities, and budgeting models. Here’s a glimpse into what we learned and how you can leverage Azure for tracking user behavior and managing costs effectively.

One of the foundational aspects of working with Azure is understanding its billing structure, which is organized into tenants, subscriptions, and resource groups. This hierarchy is crucial for managing resources and costs effectively:

Tenants: The highest level in Azure’s structure, representing an instance of Azure EntraID that houses users, groups, and applications.
Subscriptions: Each tenant can have multiple subscriptions, serving as containers for billing and resource management.
Resource Groups: Within each subscription, resources are organized into resource groups, allowing for better control and management of assets like virtual machines, databases, and more.

Grasping this structure is essential for setting up your Azure environment in a scalable and cost-efficient manner. We introduced a set-up for an infrastructure for tracking user behavior on web browsers using Azure Labs, Container Apps, Azure Storage Accounts, and SQL Servers. This infrastructure not only showcased Azure’s flexibility and power, but also its capability to handle high-volume data processing and storage efficiently. To provide a comprehensive overview, we used the Azure Price Calculator based on our infrastructure diagram. This tool allowed us to estimate costs for running our user behavior tracking system. Here’s a breakdown of the major components:

Virtual Machines and Container Apps: Costs associated with compute resources.
Storage Accounts: Pricing for data storage and redundancy options.
SQL Servers: Expenses for database instances and storage.

Using the price calculator, we were able to get a detailed estimate of our monthly and yearly costs, giving us a clear picture of the financial implications of our project. Participants of the workshop learned how important it is to know about the project and settings for the Azure components to get a detailed estimation. Otherwise, big and unrealistic surprises might hit you hard!

Throughout this journey, several key takeaways emerged for anyone considering Azure for their projects:

Understand the Billing Structure: Knowing how tenants, subscriptions, and resource groups work will help you manage resources and costs more efficiently.
Leverage Azure’s Flexibility: Use the wide range of services like Container Apps and SQL Servers to build scalable and resilient architectures.
Utilize Cost Estimation Tools: The Azure Price Calculator and budgeting models are invaluable for predicting and controlling expenses.
Monitor and Optimize: Regularly review your usage and costs with Azure’s monitoring tools to avoid surprises and optimize resource allocation.

Azure offers a powerful platform for building and managing complex projects. By understanding its billing structures, designing efficient infrastructures, and leveraging budgeting tools, you can harness its full potential while keeping costs under control. Whether you’re tracking user behavior or running large-scale applications, Azure has the tools and capabilities to support your ambitions.
