OVHcloud talks

Two talks were given by Alexandre and Olivier.

Alexandre Vilain – Temporal.io – My workflows are cloud ready

📽 Replay

Who has never found themselves developing an in-house solution to orchestrate complex business workflows? You start by adding a database to manage the state, then you add queueing to pass the data through your services and you end up developing complex retry functions that never handle all the special cases. Even before integrating their business logic, developers have to solve a number of workflow orchestration problems that make development heavy and sometimes complex to maintain. Can we stop reinventing the wheel?

Temporal.io is a workflow engine, derived from Cadence, initially developed at Uber and used in production at Netflix, Stripe or Snapchat. The paradigms brought by temporal.io are simple and allow teams to reduce their “glue-code” to focus on their business code. Write your workflows in the language of your choice thanks to its SDKs available in several languages: JAVA, Go, Typescript, PHP (and soon Python, Ruby, Rust & .NET), the temporal platform takes care of the rest.

The objective is to present you temporal.io: how it works, its use cases and its interest for development teams.

Olivier Beautier – The IT’s hero’s journey

📽 Replay

Did you know you were a storyteller?

As proof, you are able to predict the next scene in a movie or a series, or even guess who the killer is! This is completely normal, because from our youngest age, we have been rocked by stories, tales, legends, we have unconsciously integrated their mechanics.

In this original and interactive talk, we will use the concept of the Hero’s Journey to tell a story, directly inspired by your experiences, and show you that you have everything you need to tell great stories yourself.

Behind the scene

Many members of OVHcloud were at the DevFest Nantes.

It was an opportunity to meet each others in real life!

The booth

All the team was involved in the booth setup and was present on the booth during the event 👏.

The booth was amazing, thanks to @horacio for his wonderful drawings 🤩.

As a DevRel

As always being sponsor at this kind of event is a lot of work. The day start early to build the booth and to be present at the opening on the booth.

We met a lot of people with exciting discussions. We organized a contest based on the Gabaky game.

Many players came to try to win the Switch and at the end, after a memorable final, one of them won the Switch!

As a speaker (and coach)

Being a speaker at a conference is already a very strong experience, but when it comes to the biggest French conference and the talk takes place in the largest room, it’s indescribable.

In this talk where I learn to tell stories, I tell my own story and my fight against stage fright.

I manage to emerge victorious from this fight thanks to the tools of storytelling, and I transmit at the end a model of narrative structure adapted to the world of conferences.

I also had the great pleasure of being able to coach Alexandre for his talk “Temporal.io – My workflows are cloud ready”, from the design of the talk, through rehearsals in the middle of the crowd, to the final performance.

Alexandre’s talk was a success, I’m very proud of it and I can’t wait to see his next talks.

Next?

A big thanks to the whole organization team, you did an amazing work for this super edition 💪.

Can’t wait to return next year!

As speakers, we are going to tell you how this edition of the first physical edition of Volcamp went.

Few words about the conference:

OVHcloud talks

Aurélie Vache – Keynote – (What if we learned to) Learn and share differently

Abstract:

We are currently about 7.9 billion people on Earth and we are all different but we have to fit into boxes, follow the same program, and we all have to learn in the same way.

What if I told you that it is possible to learn and share differently, to appeal to your imagination and your creativity and that it is beneficial for everyone?

In this talk, I tell a story, I tell you my story, how I went from a person who had lost his passions to the creation of sketchnotes, videos, talks that are out of the ordinary and illustrated books. We will see that sharing differently, that changing things is not easy but that it is important and that it is possible with a few tips, that other people have done it and that now it’s up to you :-).

And finally, we will see that we each have superpowers to use wisely.

David Apparicio – Security at the early stage of the project

Abstract:

In 2020, the number of cyberattacks has exploded worldwide. According to a recent report from the French National Agency for Information Systems Security (ANSSI), ANSSI operations in 2020 have increased fourfold, compared to the previous year.

The Covid-19 pandemic has multiplied the opportunities for destabilization (cyber attacks) in several sectors, including health: Rouen University Hospital, Narbonne, Montpellier, Dax, Villefranche-sur-Saône, Oloron-Sainte-Marie, Saint-Gaudens … The list of hospitals is getting longer.

Moreover, since the RGPD came into force, the protection of personal data as well as the security ‘by design’ become central subjects in our projects.

I will present the techniques used and I will also talk about the management’s awareness of these important aspects. Indeed, even being in the internal network of a datacenter, we are not safe from an intrusion. The 0 risk does not exist. ~ Security By Design 101

Thierry Chantier – IoT apéro

Abstract:

After months of not seeing each other, we can finally get together with friends to share a fun and friendly time. And if we can learn and understand things that we had to struggle to understand alone, it’s a huge bonus.

This is exactly what we propose to you through the Apéro IoT whose objective will be to have fun and to have the keys to launch our first IoT project. This cocktail party will be interactive, participative (it is not impossible that we invite people to come on stage)… and also realistic (no tricks)!

Our joyful makers will be Philippe, Thierry, Louis, and you, our dear public. We will be gathered around a drink, to take a look at this complex and controversial subject.

We will propose you a hardware, SDK and languages tour so that everyone can return home with wishes and ideas of projects to test or realize.

Eléa Petton & Stéphane Philippart – How about helping Captain Nemo classify sea monsters?

Abstract:

Artificial Intelligence, Machine Learning, Deep Learning, … We hear these terms every day, but what do they actually mean and how do we develop applications based on these concepts?

During this talk we will introduce you to the world of data and how easy it is, with the right tools, to embark on the adventure of data analysis and classification.

This talk will help developers discover how to develop learning applications and show that you don’t have to be a data scientist to develop your own machine learning or deep learning algorithm. We will show you how to create your first notebook with JupyterLab to help you take your first steps. This will be an opportunity for you to dive into the discovery of the underwater world by developing a model to identify and classify the sounds of marine mammals.

Finally, we will see together, with Streamlit, how to develop an application using this model.

Behind the scene

Many members of the team were accepted as a speaker. It was an opportunity to meet each others in real life in the center of the France!

As an attendee

Thierry:

Being present at this kind of event also means having the opportunity to see talks and have passionate discussions.

On the talks side, on top of my wonderful colleagues talks, I had the opportunity to see Pierre-Marie Aubineau who was sharing his personal experience as a indie game developer.

He explained how complex this kind of adventure is, the domains to master goes far beyond coding skills.

One of those domain is the marketing side of a game launch: his views on how he failed that point were really thoughtful.

His conclusion was full of reading advices and pointer to resources : a complete tour of what you need to start a game project.

Another important thing during that kind of event is the opportunity to have unplanned discussions with people full of passion.

For example, Friday morning on my way to the first coffe of the day, I stumbled upon Paul Pinault and we started a long, passionate and intense discussion about IoT.

He shared his vision of this domain and it was an opportunity for me to confront my ideas on the subject with someone experienced. Thanks a lot Paul!

As a DevRel

A DevRel in a conference is multi-tasking!

Attendee, speaker, keynoter, … and streamer! This Volcamp was the occasion for the team to stream a live Twitch from the conference.

You can find the replay here.

And, during a conference many things can happens … for example: speak, discuss impromptu, for more than an hour, accessibility, neuro atypia, associations of women in tech and public speaking.

As a Keynoter

Aurélie:

In December 2021, I received a private message on Twitter, from an organizer, telling me that the Volcamp conference was looking for a speaker for the opening keynote and if that told me to be part of the adventure?

I admit that I have read this message several times.

Presenting the opening keynote of a conference, of their first edition in physics, is a lot of stress and pressure.

Creating this keynote was: 3 and a half months of creation, modifications, big big big doubts, revisions, the D-Day.

I was very stressed, but I really enjoyed doing this keynote, talking about a subject that has fascinated me for years, passing on the messages I wanted to convey while naturally sticking to the values ​​of the conference.

It was a HUGE challenge for me. I put a lot of pressure on myself, a keynote is not nothing.

I’m very happy with all the feedback I’ve had, from people who spontaneously told me that it spoke to them, touched them, moved them, made them think and/or that it gave them the boost to do what they wanted to do, try, dare, and that’s really great. The word that came up the most is “inspiring” and that’s really the purpose of a keynote so I’m more than happy.

I was exhausted but super happy with these 2 days full of emotions, encounters, sharing, discussions…

Thank you again to the organizers for trusting me and to my pro / community and personal entourage for always being kind to me ❤️

Because we have to say it again and again, it is important to be well surrounded in order to push back your limits and constantly move forward.

In short, being a keynoter, it’s a great experience that I’m not ready to forget! 🙂

As a speaker

Lot of talks given par someone from OVHcloud. Each experience is different but it’s always the same feeling: sharing with other people is so wonderful.

The organization was top, as in many conferences and the location very pleasant.

As a wooden C letter

Everything was going well until a certain Aurélie attacked me just before the start of the keynote, a wonderful “icebreaker”…

Accordingly, we suggest that next year the event be renamed “Volamp”.

Next?

Can’t wait to return next year! … With all the team? 😉

As speakers, we are going to tell you how this edition of Devoxx Morocco went.

Few words about the conference:
– 1200+ attendees
– 2 keynotes
– 150+ conferences
– 11 sponsors

The conference

Devoxx Morocco is a very big conference, the biggest in Morocco.
What was striking was the enthusiasm and passion with which the participants went to the talks.
There were often very nice post-talk exchanges between the whole audience.

Participating in such a conference, far from France, is an opportunity to discover another culture, both in terms of computer science and personal life.
We come back home with a lot of beautiful images, contacts with wonderful people and a lot of stars in our eyes.

Let’s see from a more standard point of view how Devoxx Morocco went!

OVHcloud talks

Horacio Gonzalez & Stéphane Philippart – How to develop a Kubernetes operator in Java with Quarkus.

Abstract:

Kubernetes operators are taking up more and more space in the Kubernetes ecosystem. An Operator simplifies the packaging and deployment of applications within Kubernetes but it also automates the operational part such as updates, migrations etc …
After a quick presentation on the key concepts of operators, this workshop will be an opportunity to dive concretely into the depths of the development of an operator.
So we are developing an operator. Great, but with which language?
For us, old developers, the choice was obvious: Java! And as we love Quarkus, we might as well mix business with pleasure: it is with Quarkus and the Java Operator SDK that we will accompany the participants of this Workshop.
We will develop a small Quarkus application and then we will code a Kubernetes Operator to package and deploy it. Finally, we will automate the operational part so that this application works perfectly and robustly. All this without leaving Java and Quarkus!
No need to be an expert in Quarkus or Kubernetes to follow the lab, loving to code and knowing the basics of Java are more than enough. You will no longer need to install anything on the machine, a simple browser and voila thanks to the power of GitPod.

Behind the scene

As an attendee

What a wonderful experience!
The location was amazing: Agadir and the Hilton.
Many of the conferences were very interesting with many conversations after each one.
And, as usual, it was the opportunity to meet some friends from other companies and have many discussions.

As a DevRel

As always in conference the meetings and other stuff for OVHcloud keep going 😉.
That’s the life of a DevRel on the road.

It was also the occasion to met other DevRel and have passionate discussions.

And of course it was an opportunity to meet many attendees, even if we didn’t have a booth 😊.

As a speaker

This is the first time Horacio and Stéphane gave this workshop.
The attendees were enthusiastic and many interesting questions were raised.
And at the end, one attendee won the Kahoot contest and won the book on Kubernetes written by Aurélie Vache.

Can’t wait to return next year!

As speakers and sponsor, we are going to tell you how this edition of Cloud Nord went.

Few words about the conference:

• 300+ attendees
• 1 keynote
• 25 conferences
• 1 round table
• 17 sponsors

OVHcloud talks

Aurélie Vache & Gaëlle Acas – Create & share a plugin for Kubernetes in few minutes? Easy!

Abstract:

Kubernetes is quite complex like that … but did you know that it is possible to add functionality to our favorite orchestrator thanks to plugins and a small tool: Krew?

We will see in this talk, that in a few minutes it is possible to create a plugin in Kubernetes to make our pods more user-friendly (depending on the seasonal theme ^^). But that’s not all ! The goal is also to share it with others and for that, Krew is “The place to be”. At the end of this talk you will have all the marbles in hand in order to be able to create & share your own plugin.

Ready? Create your own plugins!

Horacio Gonzalez – Round table on the future of the cloud

Abstract:

Horacio and other cloud specialists discuss what the cloud will look like in the years to come.

Stéphane Philippart – Kubernetes operators for any developer

Abstract:

Developing an operator can be rather impressive.
Fortunately, different Frameworks have emerged, including the best known, Operator SDK, allowing an operator to be developed in Go, Helm or Ansible.
Before develop an operator, we will see together what is behind the notion of operators within Kubernetes: what they are used for and how they evolve in the Kubernetes ecosystem.
Once these basics acquired, we will develop together an operator allowing the management of an Nginx server.
Yes but which Framework / language to choose? Go? Helm? And why not Java?
I want to offer you all three!
We will develop together the same operator in three different ways: with Helm, Golang and even in Java with Quarkus!
At the end of this talk, you will have the different elements to know if you need to develop an operator, how to develop it, and choose which language to use according to your knowledge!

Our booth

Once again, it was an opportunity to meet many interesting people.
The Gabaky contest, was again a success.
One attendee won the book about Kubernetes written by our colleague Aurélie Vache with the highest score, congratulations to him!

Behind the scene

As a team

Cloud Nord was the occasion for the DevRel team to on-board our fifth element!
Thierry Chantier joined our team in September and it was the occasion for the rest of the team to meet him in real life 😊.
It was also the opportunity to visit our wonderful office in Roubaix.

As usual local OVHcloud staff came to help us on the booth, a big thank you to them and especially to Anissa (as always your rocks!)

note from the Fitfth element:

What could be better than jumping in an event with my team straight away? The experience was smooth and each time I needed someone to dig in a topic with an attendee, someone was here. No matter if it was my team, someone from the local office and from a different service: I was able to live the One Team moment and it was wonderful!

As a speaker

As always giving a workshop allow to meet wonderful people and make easiest to have questions & answers time.
The workshop of Stéphane was the opportunity to him to zoom in and take the time to talk about topics with attendees.
A great moment!

Aurélie’s talk (and her partner Gaelle) was the opportunity, once again, to show that even if we think that a technology is complicated, Kubernetes in this case, it is possible to extend these functionalities in a simple, playful and step-by-step way.

As an … author 😆

Being at Cloud Nord as a sponsor, speaker and illustrated book writer was a special opportunity to meet all day developers, Ops, SRE, students (…) and other sponsors who were interested in the book.

Many people were attracted by the book so it allowed to have people throughout the day, constantly on the stand.
Aurélie took advantage of these moments of exchange to learn more about the use of Kubernetes by visitors and was able to redirect to the rest of the team in order to offer them demos and tell them more about existing OVHcloud solutions.

As a sponsor

The format of the conference allowed, for once, to take full advantage of the people present and coming to see us on the stand.
The Gabaky game, tested during the Sunny Tech, was a great moment of sharing with all the participants.

Can’t wait to return next year!
