7. Understanding
the problems

8. “We make a change in one place and
somewhere, something else breaks”

9. “It feels like it
takes a long time to
complete what
should be a simple
thing”

10. “Feels like all we have done are patches, hacks
and short term tactical fixes to meet deadlines”

12. Part of any problem is: people & process

13. We’re going to focus on
the technical parts

15. 1. Legacy Systems
2. Kitchen Sink Applications
3. Monolithic Applications
4. Complexity
We’ll talk about dealing with 4 things:
…and what we learnt along the way.

16. 1. Legacy Systems

17. Strangler
Pa6ern

19. Legacy systems grow arms and legs…
…because the world needs to continue

20. 2. Kitchen Sink
Applications

21. Kitchen Sink

22. Different speeds
of evolution

23. Factoring systems by
Value Stream

26. You aren’t
going to get it
right at first
go

27. Using WebAPI and
Areas to build
services within a
service

28. 3. Monolithic
Applications

34. Eliminating batch
processes is hard

35. 4. Complexity

36. “I
do
believe
that
complexity
is
the
enemy.
Un7l
we
be9er
understand
complexity,
our
chances
of
building
be9er
IT
systems
is
limited.
The
first
thing
we
must
understand
about
complexity
is
that
not
all
complexity
is
equal.
And
the
complexity
on
which
most
people
focus
is
probably
the
least
complex
complexity
of
all.”

40. Accidental
complexity
vs
Planned
complexity

41. Dealing with artifacts…

42. Managing Pipelines

43. Make
it
Visible!

44. Drilling down...

45. to package our apps

46. What’s inside the nuget
package?
Puppet

applicaOon

47. Proget to manage
the packages for
the environments

with
puppet
to
configure
the
environment
IIS
configuraOon,
Folder

etc

51. What’s interesting!!?
Packages shipped with ability configure their environment

52. Testing deployment scripts…
…with Canary packages

53. Guarantees at every every stage in
pipeline

54. Unit Testing

55. Integration Testing

56. Systems Testing

57. The test pyramid.

59. Status Checks
