# X-Ray

• Debugging in Production, the good old way: • Test locally

• Add log statements everywhere • Re-deploy in production

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

• Debugging: one big monolith “easy”, distributed services “hard” 

• No common views of your entire architecture

• Enter... AWS X-Ray!
