• Add log statements everywhere • Re-deploy in production

• Log formats differ across applications and log analysis is hard.

• No common views of your entire architecture

AWS X-Ray advantages

• Understand dependencies in a microservice architecture

• Pinpoint service issues

• Review request behavior

• Find errors and exceptions

• Are we meeting time SLA?
