35. How can you become a Logs Ninja with CloudWatch?

In the age of distributed systems we produce tons and tons of logs. This is especially true for AWS when using CloudWatch logs. So how do we make sense of all these logs and how can we find useful information in them? In this episode we talk all about logs on AWS and we discuss the main concepts in CloudWatch for logs like Log Groups and Log Streams. We discuss how you can consume logs and how this used to be a big pain point with AWS CloudWatch logs and how now things are a lot better thanks to a relatively new feature called Log Insights. Finally we discuss some best practices that you should consider when thinking about logs for your distributed cloud applications.
