 Hello, everyone. I'm Alessandro Polidore, and I'm a senior software engineer at an Italian open source company called NETASYS. I'm going to start jumping and get started. Ok, the focus of this talk is to give you a very simple method to have your next cloud installation ready to use with only one single click. Ok, but why? Why do we need a simpler solution? Let's start with three fundamental questions. Number one, how many times have you had some sort of problems installing a cloud? And to solve them, how much time have you spent on it? And of course, all the time spent fixing issues or acquiring new skills has it and costs, obviously. So what is the problem? This problem is that you need to have different kind of new religious in different fields to satisfy installation requirements, but take a moment and reflect. Most of the time, you are not a system administrator or security expert, and you don't want to know all angianics, configuration options or language optimization techniques, or so on. But probably you are a next cloud developer with a great innovative idea to develop a new killer application, and you only want a next cloud installation at your office or at your home to sharing some photos or music with your friends. So the solution is next cloud, that is an integration between next cloud, of course, and the next server operating system. Next server is a Linux distribution founded by NetEase, that is an Italian open source company. It is based on CentOS system and has a very powerful web interface to simplify all the complex tasks that the administrator have to do manually and on a daily basis. Has any other major Linux distribution has also a huge community. So the purpose is to give you a next cloud installation that you can install through the web interface with only one single click. Very, very simple. This slide compares two simplification processes. As next cloud is simplified data management and sharing, next server next cloud is simplified the installation. So the process is click and done, nothing else, and very simple. How it has been implemented? It has been integrated in the system using YAM and RPM technologies. As you know, an RPM package has the application software and plus a set of instruction to be executed to configure itself. RPM packages are distributed through the public repositories to always provide the end user with the latest up to date version. Ok, let's look at more deeply. We have two RPM packages, one is next cloud and another is next server next cloud that configure itself. It is present on GitHub and it uses an agile process release. And the repositories is public and of different types, from testing to automatic updates. Ok, another important feature is the automatic backup for all configurations and data. To use it, you have two methods. One is ISO installation and another is Vagrant. So you can choose to use ISO installation, you have to download the ISO file and this style in your server machine. You can choose also the unattended method. And then you have to do the first result and then you can install this cloud from the software center page. Nothing else and you can enjoy next cloud. If you choose Vagrant installation, the method is even more simple because you have to execute only to command. Vagrant init and Vagrant up and at the end of the installation you have your next cloud. Another advantage from the server usage is that you can install also many other open source software. As for example in my server or different account providers. As many other open source projects you can collaborate, you can join the community and participate. Not only as a developer but also for example for translating and so on. This is some references for anyone who wants to know more on the server in this cloud. And that's all. Thanks for listening.
