Observability for Modern Event-Driven Applications

Explore observability techniques for modern event-driven applications in this 45-minute conference talk from Conf42 Observability 2024. Delve into the complexities of event-driven architectures (EDA) and learn why organizations are adopting them. Discover the three pillars of observability and how they apply to EDAs on AWS. Gain insights into leveraging Amazon CloudWatch for metrics, structured logging, and anomaly detection. Explore tracing with AWS X-Ray and learn best practices for implementing observability in event-driven systems. Understand how to overcome challenges in log analysis, utilize AI-powered query generation, and bring everything together with CloudWatch ServiceLens. Leave equipped with practical knowledge to enhance the observability of your event-driven applications and ensure their successful implementation.

event-driven architectures eda
what is an event
why customers are moving to event-driven applications
but... eda is hard to get it right!
what is observability?
eda: based on domain driven design ddd and events
eda: based on ddd and events
observability matters because
traditional monitoring layers
when you do eda on aws...
aws observability maturity model
three pillars of observability
amazon cloudwatch - inbuilt metrics
cloudwatch built-in metrics
metrics - namespaces and dimensions
built-in metrics often not enough
lambda insights
structured and cetralized logging
standard structured logging
query cloudwatch logs insights
ai-powered natural language query generation
use cloudwatch anomaly detection alarms
challenges with logs analysis
pattern analysis in logs insights
aws x-ray
enable x-ray tracing
aws lambda powertools
bringing it all together
cloudwatch servicelens
best practices for observing event driven applications
summary - use observability to get eda right
