Microservice = Micro Teams

8. Microservices =
Micro Teams
“Code to Interface”
moves to infrastructure
Micro team’s service
moves at its own pace
Coordination between
people eased (Mythical
Man Month)
Feature velocity
increases

Build & Test Grids

11. Build & Test Grids
Containers start in less
than one second -
faster builds
Can test more
permutations of the
system
Increase build
parallelism
Increases feature
velocity and innovation

Configuration Mgmt

13. Config Mgmt
Learning curve of
typical CM tool is
extremely steep
Docker obviates need
for most host config
(bakery)
Containers are
configured via a
simple bash-like file.

Process Density

15. Process Density
Reduce host
consumption
reduces cost
Reduces power
footprint in large
physical setting

16. @behemphi
Dev Environments

17. Dev Environments
New team members
are productive their
first day
Innovation - try
new things quickly
Developers share
improvements easily
via familiar tools
@behemphi

18. @behemphi
Black Box FTW

19. Microservices =
Micro Teams
Compliance over
Governance
Ops role evolving
to - Compliance as
code.

20. So thaaat’s why
Docker?
