Integrating Service Mesh into OpenTelemetry Traces
The use of a service mesh in cloud-native architectures can not only increase resilience and security, but also observability.
However, there are some pitfalls that need to be taken into account in order to integrate gateways and (envoy) sidecars of the service mesh into traces.
This talk provides a rough outline of the topic and a deep dive into how the individual components need to be configured in order to obtain detailed traces that make root cause analysis (almost) child's play.
Jakarta Tech Talk - Observability for Jakarta EE Apps with OpenTelemetry
The talk provides an introduction and deep dive into the topic of observability with OpenTelemetry, hands-on with Quarkus.
You will get an overview of the possibilities of the OTEL Java APIs and an outlook on how the integration into other Jakarta EE technologies such as OpenLiberty via MicroProfile works.
The deep dive outlines the possibilities offered by baggages, how custom metrics can be created via the OTEL APIs and how spans can be linked to each other.

Back to the future - How a 2004 book helps us design cloud native software
The talk describes the possibilities of Domain Driven Design for modularising a software system to make it fit for cloud-native operating platforms.
It provides an overview of the most important terms from DDD and possible architecture patterns for concrete implementation.
