Open Source Summit + Embedded Linux Conference Europe 2020

Cloud-init may have started out as a way to customize the Amazon EC2 instance at first boot but it is now widely supported on every major Linux distribution and across many public and private clouds. With Cloud-init, you can perform any type or number of actions as it boots up on your favorite cloud - as it is designed to to run during the first boot, you don't really any additional steps or software to start utilizing it today. Join me in this demo-filled session to learn all about Cloud-init and how you can use it to customize/personalize your cloud VMs even before you log in to them for the first time!

As the cloud becomes pervasive in IT, it then becomes increasingly important to adopt cloud-native technologies. For enterprises and vendors, building in the cloud is an opportunity to refresh applications and architectures in ways that make them more flexible, scalable and resilient.  Cloud Native technologies are used to develop applications built with services packaged in containers, deployed as microservices and managed on elastic infrastructure through agile DevOps processes and continuous delivery workflows. The session explains What is Cloud Native, Why, and How to adopt Cloud Native.  This session would shed light on Cloud Native technologies and containerization, moving from a monolithic based architecture to microservice architecture, and then implementing a demo where we build containers and also migrate it to a Kubernetes environment.  

The session aims to provide an overview of containers and orchestrator technologies, with a practical focus on Docker and Kubernetes, with an introduction to the concepts and the architecture and practical examples on how to package and deploy an application into Kubernetes, using plain manifests, kustomize, helm or terraform, to show the difference between those approaches.   The session is a summary of the "Kubernetes - The Deltatre Way" series of video conferences (available here: https://www.youtube.com/watch?v=42QRgaOemqM&list=PL6vUc9GnRFV__5YsoKCRW2jRSQ47kygT2) and of the training courses about DevOps (available here: https://drive.google.com/drive/folders/1x7rfieee7yii575w7qRVB_y8TBpZI4XS?usp=sharing ).   Differently from what done in these previous versions, the session will be completely in English and will be condensed to fit in 2 hours (target 1.5 hours plus space for discussions and questions), with a focus on how to operate and control deployments.   Content used for the demonstrations is available in GitHub (https://github.com/raunodepasquale/ ) and will be updated to reflect the updated version of the presentation.  

Cloud-Native computing is the hottest trend in the cloud ecosystem and is increasingly becoming the new norm for application development and deployment. At the core of Cloud-Native Computing infrastructure are containers and with the increasing adoption of it along with the scale of deployments, security becomes an important aspect of the adoption strategy. Of the 4C's of Cloud-Native Security, containers are one of the security layers.

The sesion will provide an introduction to Container Security covering the challenges & risks around containers and various tools that can be leveraged for implementing container security. The presentation starts with an overview of cloud-native security but focuses on container security, the challenges that come with using containers. In this session you will be introduced to the type of threats in scope and some of the container vulnerabilities that are out there. You will get an introduction to various tools (mostly open source) that can be used to provide a layer of protection for your containers.

People of have stress about the unknowns of taking a practical exam. In this session, we will discuss an approach to preparing for Kubernetes certification. In keeping with the exam requirements we will not discuss specific exam content, rather use provided documentation to understand what to expect and suggestions for preparation. Question and answer session after the presentation.
