 Man, it is so awesome to be able to do a live demo and have it not crash. See if that continues throughout the day. We might have another demo later with this other server. So I told you earlier you're gonna hear about a bunch of different use cases. This first one we're gonna hear from is about enterprise big data and we've got from Banco Santander, which is an awesome bank that's all over the world and headquarter here in Spain. Juan Antonio de la Fuente from Potoban and Luis Enriquez from Santander group. Come on out. So hello, good morning. Welcome to Barcelona. So first of all, I'd like to thank to the organization for this great event and to let us share our experience with the community. We are going to try to give you during the next nine minutes a brief overview about what we are doing on the open stack and big data space. To put you in context, I would like to provide some insight about who we are and what we do. So as a company, our mission is try to be the best bank to our customers, our people, our shareholders and the community. And it means try to be the best place to work for our near 200,000 employees. It means providing relevant and personalized products and services to our customers, more than 121 million, providing value to our shareholders and have a strong focus on the community. We have a very strong relationship with the education institutions and the university. We operate across the globe in Europe and America, both as a Santander bank and Santander consumer finance. From the IT point of view, we have best-in-class data centers. We have TR4 data centers in four locations that allows us to provide service to 16 million of digital customers and allow us to process workloads for more than 122 million transactions in last year. We organize across different companies inside the group, the corporation, the countries, and then we have some companies that are specializing in different fields. So, for instance, ProDuban is responsible for the IT operations and the infrastructure and they are leading the cloud adoption and deployment. So now in the banking industry, we are facing hard times. It's challenging because of low margins are putting pressure on profitability. The customer are demanding more and more their expectations are higher every day. And also, we have a lot of pressure and competition from new entrants and shadow banking. So, we need to do different things and it means, and no surprise here, to do things quicker, better, and cheaper. And that's, I think, the good part for us as engineering and IT professionals that we are, if not the solution, at least a relevant part of the solution. So, technology is the key enabler to change and to do the things and to succeed in this hyper competitive environment. So, cloud, big data, APIs, mobile, those technology trends are behind our transformation, our digital journey, and all of them are powered by the cloud or by OpenStack. So, now it's time to, my colleague, Juan Antonio, to get into the big data theme. Thank you very much, Luis. We started our journey to cloud in 2014 based on four foundational principles. Automation and cloud-first applications to develop cloud-aware applications, decoupling business functions from technical services, and building APIs to automate the consumption internally and by external third parties. With a hybrid cloud approach, workloads to be ready to run in our private, but also in the public cloud. A secure multi-tenant environment is a must in our design, and we have a special focus as well in on reducing costs using commodity infrastructure. We have big data and real-time analytics on top of our cloud, creating new and innovative use cases to enable competitive differentiation through the management of data at a higher speed with more volume and with more variety of data. And using open source first, using open source frameworks and tools and giving back to the community directly or through partners to help them to improve and evolve the technologies. And we decided to run OpenStack as a technology enabling in our private cloud. First, to understand and to learn about the cloud technology, then to develop self-service capabilities to provision networking, compute and store resources on premises, and to migrate specific workloads like the big data ones to our OpenStack cloud. And we are doing this in a large deployment in eight regions across all of our corporate data centers in the globe with more than a thousand compute nodes running OpenStack in a couple of configuration hyperconvergence and with local storage resources to provide enough performance to the big data workloads running on OpenStack. There was a good engineering work to adapt our OpenStack cloud to run the big data workloads. That was an important effort from our engineering team. And we get that. Our environments were one if not the first cloud data certified environments running on OpenStack cloud. We have cloud data distribution in our big data analytics and real-time analytics scenarios. We are analyzing almost two petabytes of information in the different data lakes that we have. We use cases that goes from rich management, 360 customer intimate experience and knowledge and operational excellence. At the time, we started out big data projects. Sahara was not ready to to be integrated with cloud era. So what we have is automated the provision of the infrastructure part and the integration with the big data management tools is something that we are analyzing for the near future. And I would like also to mention that we've been recognized for our work in this area. Yesterday colleagues of us received the data science awards Spain 2016 in recognition for our big data corporate strategy. And I don't want to miss the opportunity of sharing with you some thoughts about two projects that we consider that are key in accelerating the cloud adoption. Those are neutron and probe. What we think it is in those projects, the community should give more support to develop and to drive the API integration because there are additional features that are provided by third-party third-party implementations. We are using some of them and we are happy using them. But we would like a neutron and probe take the control and the lead of the development of the API integration and not the other way around. And also I would like to remark that a special focus should be given to create production-credit capabilities to accelerate the cloud adoption like high availability, disaster recovery, advanced monitoring. So we think those three aspects would accelerate the cloud adoption. Thank you very much for your attention and thanks the summit organization for giving us the opportunity to share with you our experience. Thank you very much. Thank you. Thank you so much. So you mentioned that open source first is a big part of your strategy. I happen to think that's a good idea. So can you tell us a little bit more about that? Like why is open source critical to making your strategy work? Well, because it's something that allows us to contribute and to orient the way that we want the technology to evolve. And we can have some collaborations with third parties or directly to the community to request for some efforts and changes that drives the technology to the way we want to consume it. Great. Well, I promise you that the community here is going to help you out this week. And so welcome to your first summit. And thank you so much. Thank you very much, Mark.
