Silverstripe is an amazing CMS framework that competes with the biggest names in our industry. In that presentation, my goal is to convince you of this. I know that being here you are not thinking about Drupal, SiteCore or Kentico but if you have ever talked to clients, they might have challenged you on that statement? Has that happened to any of you recently? So if you still have any doubt, I will demonstrate how we made that statement come true.

The (perceived) risk of the DevOps is that too many people get the right to "break" the platform. Test Driven Infrastructure is about adapting proven ideas from our developer colleagues to the development and operations of Infrastructure services like virtualization, OS provisioning, postfix configuration, httpd configuration, ssh tuning, SAN LUN mounting and others. This talk shows how ImmobilienScout24 utilizes more and more test driven development in IT operations to increase quality and to mitigate the risk of opening up the infrastructure developmen to all developers.

Der Vortrag gibt einen Einblick in die Betriebsautomation bei ImmobilienScout24. Warum verfolgen wir eine 100%ige Paketierung aller Inhalte (Config, Software usw.) und welche Vorteile verschafft uns das? Konkrete (Live Demo) Lösungen für typische Pakete: httpd, tomcat, postfix ... Live Demo des Config SVNs und seiner Arbeitsweise Mit welchen Tricks schaffen wir das, alles zu paketieren? Wie hilft uns die Paketierung mit Dev und Ops und vielen Teams effizient zusammen zu arbeiten? Continuous Live Deployment als Weg, um das Risiko von Änderungen zu minimieren und viele parallel laufende Änderungen unter einen Hut zu bekommen. Warum modellieren wir die Abhängigkeiten zwischen Systemen, wie vereinfacht das den Job der Admins? Generell Einblick in unsere agile Arbeitsweise - Wie sieht DevOps wirklich aus? - Geschichten aus dem wahren Leben. - Ups und Downs. Die zentralen Tools sind als Open-Source Projekte frei verfügbar: http://yadt-project.org und https://github.com/yadt https://github.com/ImmobilienScout24/yum-repo-server https://github.com/ImmobilienScout24/lab-manager-light https://github.com/ImmobilienScout24/kickstart-debugger https://github.com/ImmobilienScout24/kiosk-browser https://github.com/sonatype/nexus-yum-plugin Vortragsvideo: http://www.youtube.com/watch?v=UqIY55dc_P8 Konferenzarchiv: https://www.heinlein-support.de/slac/2013/vortrag/viele-server-wenig-arbeit-betriebsautomation-bei-immobilienscout24

Viele Server - Wenig Arbeit: Betriebsautomation bei ImmobilienScout24

Schlomo Schapiro

Nutzen Sie Open-Source-Software? Haben Sie schon einmal eine Kleinigkeit ändern wollen? Konnten Sie für “Einwurf kleiner Münzen” diese Änderung machen lassen? Open-Source-Software zeichnet sich unter anderem durch die leichte Anpassbarkeit an die eigenen Bedürfnisse aus. Doch nicht jeder kann oder möchte die Software selbst ändern. Lieber würde man die Autoren oder andere Spezialisten damit beauftragen. Der Vortrag gibt Einblick in die praktische Arbeit mit dem Sponsoring von Open-Source-Projekten und beantwortet die Frage, wie man mit Hilfe von Sponsoring seine eigenen Probleme schneller und günstiger lösen kann: Nach der Vorstellung typischer Entwicklungsmodelle von Open-Source-Projekten erfahren Besucher, wie sie Kontakte zu Open-Source Projekten knüpfen können und damit jemanden finden, der ihnen weiter hilft. Weitere Themen sind rechtliche Aspekte wie ein Werksvertrag, Gewährleistung und einfache Abwicklung Anforderungen so formulieren, dass der Kundennutzen und die Nachhaltigkeit im Vordergrund steht Abnahmekriterien für den Auftrag Wirtschaftlichkeitsberechnung und Kosten-Nutzen-Abwägung Nachhaltige Lösungen statt ewigen Workarounds Mehrwert für sich und die Open-Source-Gemeinschaft schaffen Imagepflege über Open-Source-Sponsoring Eigene Open-Source Projekte durch Externe weiterentwickeln lassen Als konkrete Beispiele dienen diverse in Python entwickelte Open-Source Projekte der ImmobilienScout24.

Do you use Cloud? Why? What about the 15 year legacy of your data center? How many Enterprise vendors tried to sell you their "Hybrid Cloud" solution? What actually is a Hybrid Cloud? Cloud computing is not just a new way of running servers or Docker containers. The interesting part of any Cloud offering are managed services that provide solutions to difficult problems. Prime examples are messaging (SNS/SQS), distributed storage (S3), managed databases (RDS) and especially turn-key solutions like managed Hadoop (EMR). Hybrid Cloud is usually understood as a way to unify or standardize server hosting across private data centers and Public Cloud vendors. Some Hybrid Cloud solutions even go as far as providing a unified API that abstracts away all the differences between different platforms. Unfortunately that approach focuses on the lowest common denominator and effectively prevents using the advanced services that each Cloud vendor also offers. However, these services are the true value of Public Cloud vendors. Another approach to integrating Public Cloud and private data centers is using services from both worlds depending on the problems to solve. Don't hide the cloud technologies but make it simple to use them - both from within the data center and the cloud instances. Create a bridge between the old world of the data center and the new world of the Public Cloud. A good bridge will motivate your developers to move the company to the cloud. Based upon recent developments at ImmobilienScout24, this talk tries to suggest a sustainable Cloud migration strategy from private data centers through a Hybrid Cloud into the AWS Cloud. Bridging the security model of the data center with the security model of AWS. Integrating the AWS identity management (IAM) with the existing servers in the data center. Secure communication between services running in the data center and in AWS. Deploying data center servers and Cloud resources together. Service discovery for services running both in the data center and AWS. Most of the tools used are Open Source and this talk will show how they come together to support this strategy: AWS credential provider for employees and data center servers: http://immobilienscout24.github.io/afp/ Cloud Formation automation: https://github.com/ImmobilienScout24/cfn-sphere Compliancy with European privacy laws: https://github.com/ImmobilienScout24/aws-monocyte

How should our internal IT look in order to be a driving force for a company’s success in the digital age? This proposal is based on all my learnings from the previous 15 years and especially the Agile and DevOps revolution in IT. It takes the concept of a Product Development Organization to apply everywhere and provides a sure path to increase productivity and improve culture through technology. Transforming Corporate IT into a Workplace product takes internal IT out of the proverbial basement and puts it in the front of the internal value chain. Most of the standard tooling for product development also fits the Workplace product. This proposal is written for a typical company that employs both modern web technologies like G Suite and cloud services as well as traditional technologies like Microsoft Office and data centers.

Digital transformation is taking place across all industries, with software at the root of added value and product differentiation, and DevOps transforming the way software is created. To be a disruptor in the era of digital transformation, it is important to select the right vendor offerings to deliver the right solution. Join Michael Azoff, Principal Analyst at Ovum and Sanjeev Sharma, IBM CTO of DevOps Technical Evangelism as they discuss the evolution of DevOps and the technologies it is pushing forward. In this 60 minute interactive session Michael will share his findings from three 2016-17 Ovum Decision Matrix reports covering DevOps, Agile & ALM. Michael and Sanjeev will discuss: How Ovum sees the DevOps industry changing, and future trends Key findings from the three reports, vendor evaluation and results Making sense of open source and enterprise solutions. Why microservices should not be built without continuous delivery DevOps for multi-speed environments: legacy to containers and server-less computing How to get started and succeed with DevOps at enterprise scale

Making Sense of DevOps Tools: Open Source to Enterprise Solutions

IBM DevOps

It’s no coincidence that all the interest around DevOps today comes at a time when open source technologies and processes are so dominant in cloud computing, data storage and analysis, and--increasingly--in networking. Innovations in Linux and other projects, including containers, configuration management, and continuous integration, are what make DevOps workflows and portable application deployments possible. But it’s also the result of open source culture, practices, and the tools supporting those practices that have made iterative development and collaboration such a powerful model for creating great software in communities. And now, they’re also providing a template for how to develop and operate applications internally within enterprises. In this session, we will discuss how open source tools and practices can be applied to create effective DevOps workflows and practices.

DevOps ist aus der IT nicht mehr wegzudenken und hat sich als Arbeitsweise etabliert, die nicht nur die Qualität und operative Effizienz verbessert, sondern auch eine nachhaltige Entwicklung ermöglicht. In den meisten Unternehmen ist die IT jedoch eine Minderheit. Wie können wir mit den Ideen und Erkenntnissen aus der DevOps Welt die ganze Firma voranbringen? Warum funktioniert die agile Zusammenarbeit nicht automatisch mit anderen Abteilungen? Was macht die ITler so besonders? Die Schnittstelle zwischen allen Mitarbeitern und IT Themen ist die interne IT. Sie trägt die Verantwortung dafür, dass alle Mitarbeiter mit Hilfe von IT ihre Aufgaben effizient und effektiv erledigen können. Während die interne IT oftmals nur als Kostenstelle betrachtet wird, leistet sie in Wahrheit einen sehr hohen Beitrag zur Wertschöpfungskette: Schlechte Werkzeuge führen direkt zu langsamer Arbeit und frustrieren, gute Werkzeuge befähigen die Mitarbeiter und erhöhen die Freude an der gemeinsamen Arbeit. Heute leisten es sich viele Unternehmen noch, dass ihre Mitarbeiter auf einer digitalisierten Plattform manuelle Tätigkeiten verrichten. Messgrößen sind etwa die Anzahl der Copy-Paste Vorgänge (Mensch als technische Schnittstelle), die Anzahl an internen Emails mit Dateianhang (Dokumente werden vervielfältigt anstatt sie zentral bereit zu stellen) sowie die Anzahl der Logins die ein Mitarbeiter täglich absolviert (schwach oder gar nicht integrierte Systeme). Die Herausforderungen der fortschreitenden Digitalisierung und Verteuerung von Arbeitskraft erfordern hier auch ein Umdenken. Der Vortrag zeichnet einen Weg von DevOps in der IT zu einem neuen Denkansatz für den Umgang mit IT im Unternehmen. Dabei entwickeln sich Mitarbeiter von IT Konsumenten zu beteiligten Nutzern, die den Computer als Werkzeug für sich entdecken können. Die interne IT stellt nicht nur gute Services zur Verfügung sondern fokussiert sich auf die Produktivität und Zufriedenheit aller Mitarbeiter.

Building Better Software Faster

Sander Hoogendoorn

Project teams often use shadow IT, instead of the much slower traditional IT, to facilitate rapidly changing complex business requirements and quick release cycles. As a result, an unmanaged, ungoverned set of IT solutions reside in enterprises that keeps CIOs awake at night. This presenation also explains how enterprises can leverage cloud-enabled ALM frameworks to build managed and governed empowered IT that enables quick release cycles and template-driven rapid development, empowering developers to develop, test, and release apps in a governed secured manner.

From Shadow IT to Empowered IT

WSO2

What we've built at Zalando is complex. Supporting – profitably – a publicly traded e-commerce company that does business in 15 diverse European markets, with more than 15 million active users who all speak different languages, use different payment methods, prefer different shipping methods, and have different product tastes, has required nonstop innovation. Until recently we've focused on building a unified, comprehensive retail system, quickly, that solves just our problems. But to truly fight against complexity – particularly the accidental complexity that slows down our development process – we have adopted a microservices architecture. And when it comes to DevOps, we’ve gone a step beyond the "You build it, you run it" motto--working in autonomous teams with DevOps treated as a "first-class entity.” In this talk, Henning Jacobs (Software Architect) and Jan Löffler (Head of Platform Engineering) will share their experience implementing “Radical Agility” from a DevOps perspective. “Radical Agility” is the Zalando technology team’s multi-pronged approach to managing the complexity that results from building an architecture of massive size. Henning and Jan will focus on how microservices enable Zalando’s engineers to move faster and build systems that scale, at scale, and avoid dependencies. They will show how microservices, in conjunction with a cloud infrastructure, support teams as they try strive for autonomy. Finally, they will draw upon their experiences to show how this all works in practice, and discuss what is organizationally and architecturally necessary to make DevOps a top priority for all members of your tech organization.

Project teams often use shadow IT, instead of the more slower moving traditional IT, to facilitate rapidly changing complex business requirements and quick release cycles. As a result an unmanaged, ungoverned set of IT solutions reside in enterprises without ownership. The risks of shadow IT keeps the CIO awake at night: business continuity to data protection to unmanaged costs are just a few of these risks. At the same time, the smart CIO knows not to wage war against shadow IT because that’s what keeps the business innovating rapidly. In this session Asanka Abeysinghe, VP of Solutions Architecture at WSO2, will present how enterprises can leverage cloud enabled ALM frameworks to build managed and governed empowered IT. Topics to be discussed include, managing quick release cycles, template driven rapid development, empowering developers to develop, test and release apps in a governed secured manner, and providing internal business capabilities as APIs for application development. In addition Asanka will explain how innovative WSO2 clients are already gaining startup speed, reducing project risk, and enabling new business models by adopting WSO2 DevOps PaaS solutions

What is the role of GitOps in IT strategy? This talk gives an overview and puts GitOps into the context of current challenges in IT strategy. Main aspects are continuous delivery, policy as code, automated governance, compliant-by-default work environments, acceptable means of compliance and a comprehensive automation of all development and operations related processes with the goal of true hands-off operations. The result places GitOps as a major building block of any modern IT strategy. GitOps helps building essential key IT capabilities. It creates the motivation to truly “fix the basics” via sustainable solutions to enable creating higher level automation solutions. With GitOps engineers can focus much more on business value and spend less effort on boring IT topics.

The Role of GitOps in IT-Strategy v2 - July 2022 - Schlomo Schapiro

Schlomo Schapiro

I will show why GitOps is a major waypoint in the journey from old-style Dev vs. Ops data center operations towards a truly automated hands-off operations future. GitOps is the technological core required for compliance automation, large-scale operations, and lowering the cost of compliance & governance as well as lowering the cost of internal tooling. GitOps will give us a future, where we all take a step back, watch the bots do the admin job, and where we Dev, Ops, everybody work on improving the bots and invent new automation solutions.

Cloud, Automation und DevOps als Treiber der Digitalisierung: Wir zeigen den Weg der Deutschen Bahn in die Zukunft. Unter dem Motto “Fix the Basics” entwickeln wir grundlegende Services für Engineers, die u.a. Security- und Compliance-Prüfungen automatisieren und die Teams dadurch in die Lage versetzen, sich auf die Produktion von Business Value zu fokussieren. Einer dieser Services ist Continuous Delivery as a Service, eine anpassbare, hochautomatisoierte CD-Implementierung, die nach dem Ansatz "compliant by default" eine einfache und richtlinienkonforme Möglichkeit zum Deployment von Software darstellt. Der Vortrag zeigt auf, dass die Automation von Security- und Compliance-Vorgaben bei gleichzeitigem Fokus auf Usability für die Engineers ein kritischer Bestandteil auf dem weg zur Digitalisierung ist. Teams werden in die Lage versetzt, ihren Code nachhaltig qualitativ zu verbessern, die Unternehmen profitieren durch die folgende Innovation und die Fokussierung auf Business-relevante Lösungen. Vorkenntnisse Keine Vorkenntnisse erforderlich Lernziele * Die enge Beziehung zwischen DevOps, Continuous Delivery und Cloud kennenlernen und verstehen, warum sie eine optimale Arbeitslandschaft für Entwickler bietet. * "Entwicklerproduktivität" sollte an erster Stelle stehen, da wir so unserem Team helfen, sich auf die Entwicklung neuer Features zu konzentrieren, statt auf die Suche nach dem richtigen Werkzeug. * Automation ist die Schlüsselfertigkeit, um den Dreiklang DevOps, CD und Cloud erfolgreich zu machen. * Die Bereitstellung von grundlegenden Services in der Entwicklung versetzt die eigene Entwicklung in die Lage, echte Innovation zu betreiben.

Video: https://youtu.be/U4cHbXYy1FQ How to combine traditional IT governance with continuous delivery? Not At All! A highly automated continuous deployment environment creates a whole new world of challenges for companies to meet their compliance and governance requirements. Traditional - manual - processes don’t manage to keep up with quick and frequent releases. The solution to this conflict of interests is the automation of all compliance checks and the automated certification of every software delivery into production. Sounds obvious and simple, but it is difficult to implement. The talk shows how we tackle this topic at DB Systel and how we create solutions for automated compliance certification. See https://bit.ly/5pdops for more materials and the 5 DevOps Principles

Wie passt klassische IT Governance zu Continuous Delivery? Gar nicht! Eine hochgradig automatisierte Continuous Deployment Welt stellt die Firma vor ganz neue Herausforderungen im Bereich Compliance und Governance. Klassische - manuelle - Prozesse kommen den schnellen und häufigen Releases gar nicht mehr hinterher. Die Lösung ist die Automation aller Governance prüfungen und die automatisierte Zertifizierung jeder Softwarelieferung. Das klingt banal und einfach, ist im Detail jedoch nicht einfach umzusetzen. Der Vortrag zeigt am konkreten Beispiel der DB Systel, wie wir das Thema angehen und Lösungen für die automatisierte Zertifizierung geschaffen haben.

Video: https://vimeo.com/348556177 DevOps ist normal – oder etwa doch nicht? Wer kann das schon für seine Firma guten Gewissens sagen? Während sich die übliche DevOps-Diskussion um das Wie dreht, adressiert Schlomo die Frage, wann DevOps normal geworden ist und was dafür passieren muss, damit alle dieser Meinung sind. Von einer neuen DevOps-Definition ausgehend stellt der Vortrag eine einfache Argumentationskette für DevOps vor, in der die DevOps-Transformation mit Fahren lernen verglichen wird. So wie es heutzutage normal ist, dass die meisten Erwachsenen einen Führerschein haben, so normal sollte DevOps in jeder IT sein. Diese Analogie lässt sich auch in einem Aufzugsgespräch verwenden, um das Management von der Normalität des DevOps-Ansatzes zu überzeugen. Mit der DevOps-Definition gelingt es den Teilnehmern, jede DevOps-Diskussion zu gewinnen und damit DevOps zur neuen Normalität zu machen. Am konkreten Beispiel der DB Systel zeigt der Vortrag, wie mit dem Thema DevOps-Teams konstruktiv umgegangen werden kann.

How to convince your company that DevOps is a transitional mode of operations and the means to a goal instead of goal in itself. What comes after DevOps is “done”? DevOps is like learning to drive and a “DevOps Team” is like a motor cycle driving school. You learn in theory and practice to survive amongst “live traffic”, where other road participants are not very considerate. You have to comply with a lot of regulations. From early on you drive your motor cycle alone and the driving instructor follows you in his car keeping a safe distance. He talks with you via radio and tells you where to pay attention and how to drive. But you drive all alone and by yourself - amongst live traffic. If you hit a tree and die, it is your own fault. If you cause a crash, it is your own fault. Same about learning DevOps. You are responsible for your product in production with “live traffic” and real customers. If you crash your server, it your own fault. If your code quality causes harm to the company, it is your own fault. Your DevOps Coach sits next to you and talks to you while you type away at your screen, like a driving instructor. In the end you prove your driving skills, get your license and ride happily singing full speed into the sunset. Same about DevOps, after a training period you work alone. You build it - you run it. You go full speed ahead and deliver value over value. Who has a bumper sticker claiming “I have a driving license”? That’s why “DevOps Team” is a passing thing and once you qualify you are just an Engineering Team who are fully responsible for their product end to end. No need to put a claim to what is normal, because DevOps is normal. Video: https://youtu.be/N2EWEfhQt2M

Learn about the journey of Deutsche Bahn towards Cloud computing, DevOps and agile transformation, with special focus on our Continuous Delivery strategy and implementation. After a brief overview of what is happening at DB Systel, we will show our Continuous Delivery as-a-Service (CDaaS) approach. CDaaS is an integrative approach to Continuous Delivery ensuring governance and security compliance whilst being fully focused on the user experience. We will show the extensibility and simplicity of CDaaS and how it helps DevOps teams improve code quality. Key take aways are a profound understanding of the intimate relationship between DevOps, Continuous Delivery and Cloud which enables a truly integrated work environment for our developers. By putting ?Developer Productivity? first we ensure that our teams can focus on developing their features over choosing the right tool or knowing all platform topics in-depth

Kubernetes: Shifting the mindset from servers to containers With Kubernetes pods and containers several fundamental assumptions of server operations don't apply any more. Some Linux services like SSH even disappear and are provided by Kubernetes instead. This talk explores the mindset shift that developers and admins of Linux servers have to do in order to fully take advantage of the power of a Kubernetes cluster: * Servers turn into pods * Linux application services turn into containers * Standard services like cron and SSH disappear completely * How to separate between initialization, run and maintenance phases * Building pods with multiple containers that work together Following practical examples from real migration projects participants gain a new understanding of the role of services, init scripts, cron jobs and other standard Linux components. Key takeaways are a better understanding of how to model a complex system on top of Kubernetes and practical tips for migrating servers into Kubernetes containers. Successfully adopting Kubernetes requires a big change in how developers and admins think about servers - bigger than any change before. Bigger than the change brought by VMs. This talk shows why it pays to change traditional concepts and to embrace the new world of Linux services modularization that Kubernetes stands for. See Using Kubernetes with Multiple Containers for Initialization and Maintenance (http://blog.schlomo.schapiro.org/2017/06/using-kubernetes-with-multiple.html) for more information and a demo.

Root for All - Measuring DevOps Adoption DevOps is about culture and mindset more than about technology - but how do you measure success? How do you know if your company really "does" DevOps? It turns out that root access to production servers is not only the proverbial holy grail but actually serves as a fact-based measure for the trust and automation levels in an organization. This talk explores the connection between root access and automation on one hand and DevOps mindsets, cross functional teams and shared responsibility on the other hand. Based on practical experiences, the talk provides concrete suggestions for achieving true DevOps happiness. As a result you will know why in the end there is no harm at all in granting root access to everybody. Key takeaways are solid arguments that you can use to convince your boss and your peers to take a different approach on root access demonstrating how shared responsibility works for real. See Root for All - A DevOps Measure? (http://blog.schlomo.schapiro.org/2017/06/root-for-all-devops-measure.html) for more background information.

How many log levels do you know? How many log levels are actually useful? What is the practical difference between WARNING and NOTICE? I believe that in a world of automation, I need only two log levels: ERROR and everthing else. ERROR means that I as a human should take action. Everything else is irrelevant for me. All the other log levels are IMHO a remnant of the past from the last century. This ignite talk looks at the WARNING problem from both a Dev and an Ops perspective in order to find a useful definition for the age of automation. See http://blog.schlomo.schapiro.org/2015/04/warning-is-waste-of-my-time.html for blog article with more info.

Common wisdom has it that the test effort should be related to the risk of a change. However, the reality is different: Developers build elaborate automated test chains to test every single commit of their application. Admins regularly “test” changes on the live platform in production. But which change carries a higher risk of taking the live platform down? What about the software that runs at the “lower levels” of your platform, e.g. systems automation, provisioning, proxy configuration, mail server configuration, database systems etc. An outage of any of those systems can have a financial impact that is as severe as a bug in the “main” software! One of the biggest learnings that any Ops person can learn from a Dev person is Test Driven Development. Easy to say - difficult to apply is my personal experience with the TDD challenge. This talk throws some light on recent developments at ImmobilienScout24 that help us to develop the core of our infrastructure services with a test driven approach: - How to do unit tests, integration tests and systems tests for infrastructure services? - How to automatically verify Proxy, DNS, Postfix configurations before deploying them on live servers? - How to test “dangerous” services like our PXE boot environment or the automated SAN mounting scripts? - How to add a little bit of test coverage to everything we do. - Test Driven: First write a failing test and then the code that fixes it. The tools that we use are Bash, Python, Unit Test frameworks and Teamcity for build and test automation. See http://blog.schlomo.schapiro.org/2013/12/test-driven-infrastructure.html for more about this topic.
