Jérôme Petazzoni discusses the evolution of distributed applications and the parallels between shipping goods and shipping code. He highlights the transition from monolithic to microservices architectures and the impact of Linux containers on deployment frequency and resource efficiency. The adoption of containers has significantly reduced time-to-market and improved flexibility in application deployment.

(kind of)

3. Apps have changed
2000 2015
Long lifecycle
Fast, iterative
lifecycle
Monolithic
(one framework
one language)
Microservices
(many decoupled
components)
Scaled up
(one big server)
Scaled out
(many servers)

7. Solution:
the intermodal shipping container

8. Solved!

11. Results
● « Globalization »
● 90% of all cargo
now shipped in a standard container
● Shipping cost reduced 90%
(used to be 25% of product cost, now <3%)

13. Solution:
the Linux container

14. Solved!

15. Results
● Deploy once a day instead of once a month
● Much shorter time to market
● Resource usage improved too (2x-10x)
● Freedom: move containers around
(colo-to-cloud, cloud-to-cloud, cloud-to-colo, ...)
