6. When to go to production?
As early as possible

7. Go early to production…
Because it’s easier when the
application is small

8. Go early to production…
Because we need customer feedback

9. Production needs for microservices
• Firstly, same as development:
• Communication
• Data management
• Additional production needs:
• A place to host
• Deployment tools
• Automated continuous delivery
• Monitoring
• Scaling

11. Continuous delivery
• Be able to deploy at any time
• How we get to production
• Automated deployment
• Reliable
• Repeatable
• Efficient
• The most important feature of your product
• Feature number 1

12. Continuous delivery
Just a shell script running
automatically in the cloud

15. Why Kubernetes?
• Industry standard for microservices
• Lightweight: run it on 1 VM
• Scalable: run it on 5000 computers (or more)
• Easy to setup (at least managed)
• Self healing / automated rollbacks
• Replication and load balancing
• Automatic scaling
• Automatable API
• Open source + community + eco system

16. Why Terraform?
• Infrastructure as code
• Declarative
• Multi-vendor (works with any cloud)
• Universal configuration language
• It’s smart
• Open source

17. One database per microservice

18. The database
• One database per microservice
• Single or multiple server
• Keep the server separate from the cluster

24. That’s it...
•Go to production early
•Continuous delivery is just a shell script in the
cloud
•Kubernetes is awesome
•It’s not actually monolith vs microservices,
there’s a spectrum of choices.
