7. Command line debugging - it’s great but...
• Limited amount of commands
• Output is not always clear
• Complicated to use
• Requires more investigation
7

8. Local debugging - it’s also great but...
• Production configurations
• Application’s state
• Production’s bugs
8

9. Logging and tracing - it’s still great but...
• Time consuming
• Can you predict your bugs?
• Do you really log every line of code?
• Performance and storage cost
• Maintenance maintenance maintenance
9

10. Remote debugging - again, great but...
• Stopping the app
• Need to know the server intimately
• Impossible in cloud (many servers)
• Security
10

11. Deploy to production blindly
Well....
11

12. Challenges in cloud debugging
• Giving up the control
• High complexity architecture
• Dynamic environment changes
• Access
12

13. Solutions -
APM tools
• Low fidelity data
• Significant learning curve
• Multiple tools to monitor various
aspects of the application
• Consumes more resources, and
drives up costs
13

14. Solutions -
Exception catching
14
• Another tool
• Bugs often do not come from
exceptions
• Can act differently in various
environments
• Not all data is available
(requires deeper investigation)

15. Solutions -
Live debugger
15
• Creating the original state of the
application.
• The code behaves exactly as it
does in production.
• Reproducing bugs
• high-fidelity data wherever your
code is running, even in the cloud
• No performance impact
• Non breaking breakpoint

16. What is Rookout
• Rookout is a platform for live-data collection
and debugging
• Rookout’s non-breaking breakpoints let you
collect any type of data on the fly with no
extra coding, redeployments, or restarts
