question for the room… what parts of DevOps change significantly in a Dockerized world?

Slide 11

Slide 11 text

how long does it take YOU to ship 1 line of code into production?

Slide 12

Slide 12 text

how do you overcome the obstacles? devOps? automation? architecture? culture change?

os, lang & infra coupled os & lang coupled n-tier 2000s service oriented 2010s completely decoupled micro services 2020s sw architecture is evolving

our problems • higher complexity • bugs harder to ﬁnd and ﬁx • forced homogeneity • scaling was all or nothing • every change required complete regression testing • continuous deployment nearly impossible

Slide 15

Slide 15 text

microservices to the rescue split your application into smaller services that each perform one business function

Slide 16

Slide 16 text

simplicity each microservice can be maintained independently by a small team

Slide 17

Slide 17 text

independence each microservice can be deployed independently

Slide 18

Slide 18 text

scale each microservice can be scaled up or down as needed

Slide 20

Slide 20 text

availability bugs only affect parts of the application and can be fixed quickly

Slide 21

Slide 21 text

heterogeneity team can choose language, technology, tools that are best for the service

Slide 22

Slide 22 text

faster testing only the microservice that changed needs to be tested

Slide 23

Slide 23 text

easier continuous delivery each microservice has its own delivery pipeline ui api db ui api db code continuous integration ui api db api ui api db api ui dev test prod deployment pipelines

microservices @ Shippable availability bug life 95% to 99.99% 3 wks to < 3d deployments 1/wk to > 50/wk costs 44K to 4K

6 tips to move to microservices • move to a distributed source control system • build new functionality as a microservice • convert existing components gradually • containerize your application • implement CI/CD • invest in monitoring

Slide 38

Slide 38 text

benefits we’ve seen with mono-repo Better developer testing Reduced code complexity Effective code reviews Sharing of common components Easy refactoring The results? Our productivity has increased at least 5x, while still reaping the beneﬁts of microservices
