WHY would you go MC ?

5.
● Really high availability
● CP and DRP at the same time
● Use the best of each cloud provider - no lockin
● A very cool score meter 😎

WHEN and WHERE would you go MC ?

● France: No “mature” french cloud provider
○ OVHCloud, Scaleway, Outscale
● AWS / Azure
○ Datacenters in France (Paris)
● GCP
○ Belgium or Germany
● AWS / GCP / AZ

Should I need a LCD ?
or maybe and OLED...

13.
Find the Lowest Common Denominator
● LCD = Lowest Common Denominator
● You can’t really find a 1:1 match between cloud providers
● What will it be on-premise ?

15.
Building Bricks
● S3 like storage must be available
● LoadBalancer as a Service must be available
● Storage class ReadWriteOnce
● Instances types are hard to compare

Conclusion
● Building a multi-cloud native app is more difficult that you might
think at first
● Often the more portable way is the best one
● Architecture and preparation is key
● A few techs are multi-cloud ready and will pass a “in vivo” test
● But once you found it, value it …

Questions

23.
Merci !

24.
Appendices

25.
Networking
● How the nodes will reach each other ?
● What kind of CNI ?
● Load Balancers with private connectivity

26.
Service Mesh
● Service Mesh is powerful but also complex
● Istio can be setup as multi-cluster / multi-network / multi-mesh
● Provides internal split horizon DNS at zero cost
○ whoami.eu1 / whoami.eu2 / whoami.eu3 / whoami.global
● Unexpected bonus: Security and Observability

27.
Service Mesh

28.
kubernetes
● Managed ?
● Vanilla or Packaged ?

29.
Data storage
● Handle different use cases
● You might need a DB that is replicating data cross-sites
● The key is network latency and disconnect handling
