Debian - The Best Linux Distribution - Michael Meskes, credativ Group
Debian is the Linux distribution that is composed entirely of free and Open-Source Software and it is by far the largest Linux distribution available. The development is carried out over the Internet by a team of volunteers guided by three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines, documents that in themselves have had a lasting influence on the free software world. With this presentation the phenomenon of the Debian project is explained, from its beginning to the current time, both on the technical side as on the organisational side. Debian has a lot more to offer than one can see on first glance, so it also shows why users should care and which advantages can be received from using Debian.

Rethinking the OS: A Travel Journal - Federica Teodori, SUSE
A new wave of Operating Systems optimized for containers appeared on the horizon making us excited and puzzeled at the same time.
"Why do we need anything different for containers when traditional OSs served us well in the last 25+ years?" "Isn't Kubernetes just another package to install on top of my favorite distro?"" Will this obsolete my whole infrastructure?" are some of the questions this talk will shed some light on.
Explore the journey SUSE made in rethinking the OS: From a conservative linux distribution to a platform that goes hand in hand with the needs of Microservices.
You will get an insight at what lessons were learned during the intense development effort that lead to SUSE Containers as a Service Platform, how the obstacles along the way were lifted and why "Upstream first" is - and should always be - the rule.

WalB: Real-time and Incremental Backup System for Block Devices - Kota Uchida, Cybozu, Inc.

WalB is an open-source backup system that consists of block devices, called WalB devices, and userland utilities, called WalB tools. A WalB device records write-I/Os. WalB tools extracts them to create restorable snapshots in an incremental manner.

Compared with dm-snap and dm-thin, WalB is designed to achieve small I/O latency overhead and short backup time. We conducted an experiment to take an incremental backup of a volume under random write workload. The result confirms those advantages of WalB.

Cybozu cloud platform, which has 500TB volumes and processes 25TB write-I/Os per day, is required to achieve (1) stable workload performance without I/O spikes which may affect application user experience and (2) short backup interval specified in our service level objective. WalB satisfies the requirements, while dm-snap is not enough to and dm-thin is not expected to.

OSS CVE Trends - Kazuki Omo, Secure OSS SIG & SIOS Technology Inc.
Nowadays security incident is increasing more and more. Then lots of vendor/community/institute are making efforts to find vulnerability on software. Not only commercial software, but also OSS is having vulnerability (remember HeartBleed, DirtyCow, and so on). Then lots of security researchers are reporting vulnerability and publish it with CVE-ids which is assigned by MITRE.

In this Presentation, Kazuki Omo will report recently trends of OSS CVE (2015-2017), and tell what kind of vulnerability are focused nowadays and how you can get vulnerability information quickly.

Building, Deploying and Testing an Industrial Linux Platform - SZ Lin, MOXA
To introduce a robust, secure and reliable platform for the industrial environments is a key challenge. Therefore, running with the industrial-grade Linux distribution to fulfill the requirements mentioned above is imperative. The Linux distribution includes the Linux kernel and user space. Based on this testing design, the distribution will be built, deployed and tested in the device under automatic test by using continuous integration development practice to withstand the harsh industrial environments.

In this presentation, SZ Lin will introduce how the industrial-grade Linux distribution is built, deployed and tested without human intervention, and review the test scope in both Linux kernel and user space. In addition, he will also address the design architecture of 24/7 long-term automated testing in all device under test with each release of new update.

Kubernetes & SDN for MEC (Multi-access Edge Computing) Deployment - Hyde Sugiyama, Red Hat APAC Office of Technology
MEC(Multi-access Edge Computing) will be deployed at each distributed edge network node rather than deploy at centralized big datacenter. To run many Value Added Service applications on MEC servers in edge network nodes that rack space is limited, we need high density virtualization and cloud-native agile solution.
The container virtualization technology orchestrated by Kubernetes is evolving by the cloud industry while OpenStack becomes the de-facto NFV platform of the Telecom carrier industry.
OpenShift container platform has been designed based on Docker and Kubernetes concept and it can run on OpenStack NFV platform, VMWare, AWS, Azure and Google Cloud Platform.
This session will discuss MEC(Multi-access Edge Computing) deployment architectures and its challenges by adapting OpenShift Container Platform, SDN technology and Switch fabric for edge platform infrastructure.

Protecting Privacy with Federated and Self Hosted Clouds - Frank Karlitschek, Nextcloud
The privacy and the personal data on the internet are under attack by hackers and international espionage programs. If we want to use the internet as a free and democratic medium again then we have to fix the internet to provide the security and privacy that people deserve.

The internet and the world wide web were originally designed as distributed and federated networks. In the last few years we've seen a trend to more centralized services. This makes censoring of content, surveillance, hacking and espionage very easy. The internet community has got to go back to a more federated approach -- back to the internet's original intent.

This talk will cover the current problems with surveillance and espionage and strategies on how to fix this problem. It will also discuss the current and upcoming federation features of Nextcloud and how to become part of the community.
