Hi, I'm James Eastham, a developer advocate at Datadog. In this video, you'll discover how SPAN links provide an alternative approach for understanding cause and effect in event-driven systems. We'll explore the challenges of using parent-child relationships in distributed tracing and how SPAN links can simplify complexity. Learn to visualize and analyze these links in your observability backend, keeping traces independent while maintaining clear cause-and-effect relationships within your system. 00:00 Introduction to SPAN Links 00:12 Understanding Distributed Tracing 01:17 Challenges with Parent-Child Relationships 03:29 The Power of SPAN Linking 06:03 Visualizing SPAN Links 08:41 Conclusion and Next Steps

The Rust Lambda runtime just hit 1.0 and GA 🚀 We break down what that really means (no, it’s not a managed runtime), share progress on our event-driven chapter + observability, and tease the next big ...

Hi, I'm James Eastham, a developer advocate at Datadog. In this video, discover why distributed tracing is crucial for observability in asynchronous systems. Forget about relying on log statements and learn how asynchronous communication between producers, consumers, and message channels complicates understanding of cause and effect. I delve into how distributed tracing can track requests across multiple services, explaining trace propagation, spans, and the context they provide. You'll also see how to implement trace context injection in cloud events and how different tools like Datadog and Open Telemetry can simplify the process. Stay tuned for the next video on span linking versus trace propagation. 00:00 Introduction to Distributed Tracing 00:23 Understanding Asynchronous Communication 01:10 Challenges with Observability 03:20 The Limitations of Logging 04:13 The Power of Distributed Tracing 06:54 Trace Propagation Explained 07:53 Manual Trace Injection and Extraction 10:18 Challenges with Trace Propagation 12:37 Looking Ahead: Span Linking 12:56 Conclusion...

Hi, I'm James Eastham, a developer advocate at Datadog, and in this video, I team up with my colleague Scott Gerring to share a strategic approach to designing new software. We delve into the importance of focusing on user needs rather than technology from the get-go. Our journey starts with exploring 'domain storytelling,' a technique to better understand systems by mapping out user interactions, work items, and backend systems. We use a hypothetical app, 'Sticker Landia,' to illustrate our approach and show how it can lead to meaningful, user-focused software design. Join us as we highlight the steps to map out service boundaries and set the groundwork for building effective software solutions. Drop your thoughts and suggestions in the comments and don't forget to subscribe for more insights into modern software engineering! 00:00 Introduction: The Right Way to Start Designing Software 01:22 Problem Statement: The Sticker Landia App 02:42 Understanding...

Hi, I'm James Eastham, a developer advocate at Datadog. In this video, we'll discuss the problems associated with building asynchronous systems, including the challenges of temporal and runtime coupling, and how they can lead to outages. We'll explore the differences between synchronous and asynchronous communication, the role of message channels, and the types of messages like commands and events. Lastly, we touch on the complexities of understanding cause and effect in distributed systems and the importance of focusing on units of work within observability. Stay tuned for the next videos in the series where we'll delve into solutions like distributed tracing and span linking. 00:00 Introduction to Asynchronous Systems 00:24 Understanding Synchronous Communication 01:25 Challenges of Synchronous Systems 03:19 Transition to Asynchronous Systems 05:21 Types of Messages in Asynchronous Systems 07:25 Point-to-Point vs. Publish-Subscribe 08:59 Observability in Asynchronous Systems 10:13 Conclusion and Next Steps
