Slide 8

Do you remember old times? The stories of the grumpy old dev... #multicloud @LostInBrittany

Slide 9

In a time almost forgotten When even internet was young... #multicloud @LostInBrittany

Slide 10

Web architecture was easier... One application server, one DB #multicloud @LostInBrittany

Slide 11

Until somebody asked... What if the app server goes down? #multicloud @LostInBrittany

Slide 12

And we added redundancy With a step price: load balancer, session affinity... #multicloud @LostInBrittany

Slide 13

And down the rabbit's hole... Buuut…. if the DB goes down now? #multicloud @LostInBrittany

Slide 14

And we added redundancy again Again with a step price: DB sync... #multicloud @LostInBrittany

Slide 15

We have been doing that for years From disks to datacenters #multicloud @LostInBrittany

Slide 16

Redundancy has always a price In money and in complexity #multicloud @LostInBrittany

Slide 17

Not having it also has a price Often worse... #multicloud @LostInBrittany

Slide 18

Now we are flying to the clouds #multicloud @LostInBrittany

Slide 19

And the questions come back Heuh… and if the cloud falls down? #multicloud @LostInBrittany

Slide 20

And again, answer is redundancy #multicloud @LostInBrittany

Slide 21

Why multicloud? Because putting all the eggs in the same basket is kinda risky... #multicloud @LostInBrittany

Slide 22

Having only a cloud provider Conforting sensation of simplicity #multicloud @LostInBrittany

Slide 23

One Cloud to run your apps all Is it really a good idea? #multicloud @LostInBrittany

Slide 24

What could possibly go wrong? #multicloud @LostInBrittany

Slide 25

Service interruption The first risk we think of… But not the only one! #multicloud @LostInBrittany

Slide 26

Geopolitics #multicloud @LostInBrittany

Slide 27

Geoeconomics #multicloud @LostInBrittany

Slide 28

Distortion of competition #multicloud @LostInBrittany

Slide 29

Data sovereignty CLOUD Act, PRISM... #multicloud @LostInBrittany

Slide 30

Compliance GDPR, bank and insurance regulations... #multicloud @LostInBrittany

Slide 31

But I can always go away Can't I? #multicloud @LostInBrittany

Slide 32

Well, not so simple... Vendor lock-in #multicloud @LostInBrittany

Slide 33

Technical vendor locking Proprietary APIs and products #multicloud @LostInBrittany

Slide 34

Cost-based vendor locking Data transfer prices #multicloud @LostInBrittany

Slide 35

What can I do then? Quit the Cloud? Going raise goats in Larzac? #multicloud @LostInBrittany

Slide 36

Building a multicloud strategy Hey, even Gartner agrees it's a good idea! #multicloud @LostInBrittany

Slide 37

Multicloud can be daunting Too much complexity! #multicloud @LostInBrittany

Slide 38

The mix and match strategy Taking the best of each provider #multicloud @LostInBrittany

Slide 39

The SDDC based multicloud Software-defined data-centers #multicloud @LostInBrittany

Slide 40

OpenStack Multicloud Low level open source cloud platform #multicloud @LostInBrittany

Slide 41

Useful for hybrid clouds Most private clouds are based on OpenStack Many cloud providers offer OpenStack, managed or not @LostInBrittany #multicloud

Slide 42

Multi-region OpenStack Doesn't scale very well... #multicloud @LostInBrittany

Slide 43

Very powerful... But also rather complicated to master #multicloud @LostInBrittany

Slide 44

Kubernetes based multicloud Higher level open source multicloud #multicloud @LostInBrittany

Slide 45

Kubernetes Federation #multicloud @LostInBrittany

Slide 46

Multi-cluster Istio #multicloud @LostInBrittany

Slide 47

Kubernetes is easier for devs But you need good devops/SRE… or managed K8s #multicloud @LostInBrittany

Slide 48

Conclusion That's all folks! #multicloud @LostInBrittany
