Title

AWS re:Invent 2022 - Scaling .NET applications with asynchronous workflows (XNT404)

Summary

The session focused on building event-driven architectures for .NET applications, specifically addressing challenges with API-based integration.
Three AWS services were highlighted: Amazon SQS (Simple Queue Service), Amazon SNS (Simple Notification Service), and Amazon EventBridge.
The presenters discussed the benefits of asynchronous point-to-point queue-based integration, PubSub patterns, and event-driven applications using a message router or bus.
Observability was emphasized, with a focus on OpenTelemetry Standard and AWS X-Ray Service for tracing and reconstructing a chain of events in distributed applications.
Demonstrations included using the .NET SDK to integrate with AWS services, managing message visibility in SQS, message filtering in SNS, and event pattern matching in EventBridge.
AWS X-Ray was showcased for visualizing application architecture and identifying performance bottlenecks.

Event-driven architectures help in decoupling producers and consumers, which is beneficial for microservices-based applications.
SQS provides a robust queue-based integration pattern with features like dead letter queues and message group IDs for ordered processing.
SNS supports PubSub mechanisms with message filtering capabilities, allowing for efficient message routing based on attributes.
EventBridge facilitates event-driven application design by integrating with AWS services and third-party SaaS providers, supporting complex event routing and transformation.
OpenTelemetry provides a standardized way to collect telemetry data across various languages and frameworks, enhancing observability in cloud-native applications.
AWS X-Ray offers powerful visualization tools for service maps and trace analysis, aiding in quick root cause analysis and performance optimization.
The session underscored the importance of observability in distributed systems and the ease of integration provided by AWS SDKs for .NET developers.
