3. “DevOps” - Buzzword of the century

4. A DevOps definition?
“DevOps is the practice of operations and development
engineers participating together in the entire service
lifecycle, from design through the development process to
production support.”

“You should hire a
DevOps to comply”
“If you use our tool,
you are DevOps
compliant”

11. Agile

12. Advantages/Disadvantages
+ Many!
- Operations not capable of handling frequent releases

13. DevOps Days
In 2009 Patrick Debois founded DevOps Days in Belgium
The term “DevOps” grew from there...

14. DevOps

15. Advantages
Everyone is working towards the same goal
Operations starts using even more automation tools
Include operations in development teams

16. The big conclusion
It took a Japanese car industry and 50 years of failed
software projects to realize the following: if you are a
bunch of people, working towards a common goal, you
probably need to work together.

19. Monitoring Umbraco Cloud
Error Management FTW

20. So what are website errors?
• When something unexpected fail happens
• Website errors are separated in:
• Client-side errors (4xx)
• Server-side errors (5xx)
• According to Pingdom, 500 (Internal Server Error) is the
most common website error followed by 404 (Not
Found)

21. Why is it important to monitor errors?
• All errors are experienced as YOUR fault by the user
• Errors causes users to bounce off your website
• Errors in checkout flow and similar causes customers to
spend their money elsewhere
• Errors sends an unprofessional signal to your users
• Errors makes your users talk negative about you to their
friends

22. “But, a CMS doesn’t fail!”
Other people introduce bugs as well (even Umbraco HQ)
Your co-workers introduce bugs (you don’t obviously)
Users use your system in unintended ways
Links die
Etc.

23. How well does Umbraco Cloud handle errors?
• Very well!
• Every error is logged through log4net
• Database
• Windows Event Log
• Files
• ...
• Umbraco supports extension points for listening for
errors
• Custom error pages

24. What about presenting errors?
• Not very well!
• Based on log4net
• Unstructured
• No good visualizers
• No notifications
• Simple backoffice UI with no notification support
• The Umbraco community have build custom logging
packages
• Long way between the good packages
• Still based on log4net

25. What are the alternatives?
• Use a better log4net appender
• Elasticsearch + Kibana
• RavenDB
• MongoDB
• ...
• ELMAH
• Cloud based solution like elmah.io
