Go Cloud, young person! Beware of broad call to action…

A global injunction: migrate to the Cloud Everybody pushes to the Cloud

But how to do it? Is there a one-size-fits-all solution?

Cloud means different things to different people Different contexts, different needs, different maturities…

How can I go to the Cloud? The best answer is “It depends…”

Every organisation is now producing software And they challenges are similar yet very different

There are 5 main strategies

What do they expect from the Cloud?

Where are they in the travel to the Cloud?

Our approach to this cloud migration Three broad categories according to maturity

And we try to address the try categories With products fitting the different use cases

Hey, dude, you promised us some examples Time to begin telling stories!

The e-commerce site Small infra but critical

A simple webapp infrastructure ● Platform with webapps, CMS, e-commerce ● 20k users per month

Their Cloud: an IaaS solution Using our Openstack based Public Cloud

What did they gain? Better use of resources

Microservices and containers The Cloud Native company

An e-commerce microservices architecture

Already in Cloud Native architecture They began with Docker, then Kubernetes, all by themselves

They wanted to go to the cloud

A Cloud Native cloud

Kubernetes can be wonderful

But it comes with a price…

There are 3 main roles around Kubernetes Each role asks for very different knowledge and skill sets

Going to a Managed Kubernetes simplifies it As they don’t build and rack their own servers!

The small bank With its Mainframe

Most banks still use Mainframes With code written decades ago…

And lots and lots of Java code… And the tooling infra-as-code written around it

Step by step to the Cloud An hybrid cloud approach Several new projects in the Cloud, legacy on premises

But what about sensitive data? Banking and insurance regulations

Hosted Private Cloud Your own dedicated cloud

That’s all, folks! Thank you all!
