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

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

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

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

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

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

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

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

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

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

Now we are flying to the clouds #multicloud @LostInBrittany

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

And again, answer is redundancy #multicloud @LostInBrittany

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

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

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

What could possibly go wrong? #multicloud @LostInBrittany

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

Geopolitics #multicloud @LostInBrittany

Geoeconomics #multicloud @LostInBrittany

Distortion of competition #multicloud @LostInBrittany

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

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

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

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

Technical vendor locking Proprietary APIs and products #multicloud @LostInBrittany

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

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

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

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

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

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

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

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

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

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

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

Kubernetes Federation #multicloud @LostInBrittany

Multi-cluster Istio #multicloud @LostInBrittany

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

Conclusion That's all folks! #multicloud @LostInBrittany
