Practical Debugging at Scale: Serverless Debugging Introduction -P. 36

In this video I introduce serverless debugging focusing on AWS Lambda. Due to the lack of standardization in the field it's very hard to provide general debugging guidelines for serverless. Learn to debug like a senior developer with this comprehensive debugging course. To learn more check out https://debugagent.com/ This video is a part of the fourth module covering debugging in the cloud and production. This module focuses on the technologies and challenges posed by production environments. The discussion covers both theory and specific technologies ranging from Kubernetes to Lambda. By leveraging these tools and techniques you will gain access to the secret weapon of senior developers and consultants. This will make you a better developer and a happier one. Stop treating debugging like throwing out the garbage and treat it as a skill that you should improve. In the following modules we cover: * Debugging Theory - Ever spent all night on a bug only to find out it was a "stupid" thing that you missed in the beginning? We all have! There's a systematic process for tracking an issue that reduces the chance of this recurring. * Code - This isn't a course on coding. You should know how to do that before you start. But how do you write code that's easier to debug? Code that fails in predictable ways. Code whose failures are easy to understand and track. Code that doesn't drain your bank account because it overuses cloud resources. * Kubernetes - Not only is Kubernetes hostile to debugging, it does that on a scale that creates its own set of problems. Add the complexity of production debugging to the mix and we've got a new set of problems. * Serverless - Kubernetes has an ephemeral state problem, serverless takes that problem to a completely new level. * Fullstack - As we chase a bug we need to venture outside our comfort zone. To tiers and tools we might not be as comfortable with. In this module we'll discuss debugging the frontend and the database to create a tongs motion around the bug. * Observability - Production debugging is really about observability. Yet so many of us leave these tools to the DevOps team. In this module we'll cover these tools from a developer perspective. The full course includes more than 5 hours of video material. 00:00 Introduction 00:43 Costs 00:57 Debugging 01:17 Staging - Production Drift Apart 01:38 Serverless = Duct Tape 01:58 Lambda 02:44 Serverless Debugging: Oxymoron? 03:53 Local Debugging & Feature Flags 04:10 Staged Roleouts 04:48 Testing 05:09 Logging 05:46 Idempotency 06:30 External Influence 07:43 Staging and Dev 08:39 Consistency 09:04 Final Word
