.NET Deployment Strategies: the good, the bad, and the ugly

Ever wonder how other teams deploy their software? It’s hard to know what goes on behind the walls of another company and even harder to learn from their mistakes. At Octopus Deploy, we see a broad range of deployment strategies and techniques. Some are extremely effective, some … well, not so much.

Join Octopus Deploy Solution Architect Damian Brady as he takes you through a range of delivery strategies employed by development teams all over the world. How do teams overcome the challenges of delivering quality software and which techniques work in which scenarios?

You'll see everything from "what were they thinking!" to "it must be black magic!" and hopefully walk away with some ideas of your own.

17. @damovisa | #KCDC16 We make software
18. @damovisa | #KCDC16 List of things that matter in software development 1. Delivering working software to users Working software Delivery to users
19. @damovisa | #KCDC16 Code not in production is 0% done
20. @damovisa | #KCDC16 So what’s wrong with this?

25. @damovisa | #KCDC16 We need more governance!
26. @damovisa | #KCDC16 The Bureaucratic Deployment Cycle
27. @damovisa | #KCDC16 The Bureaucratic Deployment Cycle Our deployments are so far apart Because we have to test so many changes Because our deployments are so far apart
28. @damovisa | #KCDC16 Slowing down can make things worse
29. @damovisa | #KCDC16 Automation
30. @damovisa | #KCDC16 Scripts are repeatable and trustworthy*

36. @damovisa | #KCDC16 The Virtuous Deployment Cycle
37. @damovisa | #KCDC16 The Virtuous Deployment Cycle We deploy frequently Which gives us confidence in our process So we’re comfortable deploying frequently
38. @damovisa | #KCDC16 Summary Get it in production Bureaucracy only gives the illusion of safety Automate the whole process Fail happily in pre-production @damovisa | #ndclondon
39. @damovisa | #KCDC16 Production deployments should not be a big deal
