+
+[Azure Application Insights](https://azure.microsoft.com/en-us/products/monitor)
+is a powerful application performance management (APM) service that enables
+real-time monitoring and analysis of live applications. It helps in detecting
+issues, diagnosing performance bottlenecks, and understanding how users interact
+with applications. Application Insights supports a wide range of platforms,
+including .NET, Java, Node.js, and more, allowing for comprehensive
+observability of your application’s performance and availability.
+
+### Use cases
+
+Here are a few example scenarios:
+
+- Monitor the performance and response times of API endpoints.
+- Detect and diagnose performance bottlenecks or exceptions in real-time.
+- Track user interactions and flows within the application.
+- Analyze the overall health and performance of distributed microservices.
+- Collect custom telemetry data for deeper insights into specific application
+  components.
+- Correlate logs, traces, and metrics to detect potential application issues
+  early.
+
+### Reference of usage in our organization
+
+Azure Application Insights is deeply integrated into the IO infrastructure for
+monitoring and observing the performance and availability of all deployed
+applications. It is used to track the health of services, collect custom
+telemetry, and monitor application dependencies to ensure smooth operation.
+
+- [Resource definition](https://github.com/pagopa/io-infra/blob/main/src/common/_modules/monitoring/appi.tf)
+  to provision Application Insights resources for real-time performance
+  monitoring and diagnostics for various services in our platform.

+
+[Azure Storage Account](https://azure.microsoft.com/en-us/products/category/storage)
+provides highly available, secure, and massively scalable cloud storage for
+storing any kind of data—blobs, files, queues, tables, and disks—accessible from
+anywhere in the world via HTTP/HTTPS. It offers multiple storage types including
+blob, file, table, and queue, suitable for various use cases from static website
+hosting to backup and disaster recovery.
+
+### Use cases
+
+Here are a few example scenarios:
+
+- Store unstructured data such as images, videos, and documents using Blob
+  Storage.
+- Host static websites directly from blob storage with scalable performance.
+- Implement queues for asynchronous message processing between application
+  components.
+- Store and retrieve structured NoSQL data in a Table Storage.
+- Manage large volumes of logs and backup data efficiently.
+- Securely share files with managed access via Azure File Shares.
+
+### Reference of usage in our organization
+
+The Azure Storage Account service is widely used within the IO infrastructure
+for multiple purposes, such as storing logs, handling notifications, and
+providing durable storage for various workloads. All Function Apps deployed in
+the infrastructure have an associated Azure Storage Account to manage state,
+queues, and other necessary storage needs.
+
+- [Storage definition](https://github.com/pagopa/dx/blob/main/infra/modules/azure_function_app/storage_account.tf)
+  to provision Storage Accounts for different services, including log management
+  and notification processing.
+- [Used for notification Queue](https://github.com/pagopa/io-infra/blob/1d85e07b25c3c1c26dd36a25245abcfec87be56e/src/domains/messages-app/07_function_pushnotif.tf#L27)
