“The Elements of Style” is one of the most important and foundational guidelines on how to write well. It has effectively summarized, in a list of seminal guidelines, how to harness the power of the English language to write high quality prose of almost any kind. In computing, we have similar guides for various technologies. Python offers “The Zen Of Python”, Ruby has “The Rails Doctrine”, and so on... One of the powers these documents wield is that they help serve as a “north star” that guides an entire community toward the same goals. I believe we need a similar guide for Kubernetes. It would describe how app developers and operators should think about and use the features in Kubernetes to build and deploy reliable, stable apps. Armed with such a guide, we could all hope to better understand the “essence” of Kubernetes in pursuit of building better cloud native apps. We don’t have anything like this today, but many in the Kubernetes community have strong, detailed opinions for what should go in this guide. Much of it is tribal knowledge or scattered in blog posts. In this talk, I’ll try to bring many of these opinions together and lay out an “Elements of Kubernetes” guide for app developers and operators alike. I’ll do so by relating each “element” to stories and details I’ve seen in the community that reveal what makes a good Kubernetes and cloud native app. This talk was given at KubeCon / CloudNativeCon 2017 on December 7th, 2017 in Austin, TX

DevOps on AWS: Deep Dive on Continuous Delivery and the AWS Developer Tools

Amazon Web Services

Today’s cutting-edge companies have software release cycles measured in days instead of months. This agility is enabled by the DevOps practice of continuous delivery, which automates building, testing, and deploying all code changes. This automation helps you catch bugs sooner and accelerates developer productivity. In this session, we’ll share the processes that Amazon’s engineers use to practice DevOps and discuss how you can bring these processes to your company by using a new set of AWS tools (AWS CodePipeline and AWS CodeDeploy). These services were inspired by Amazon's own internal developer tools and DevOps culture.

Resilience with Hystrix

Uwe Friedrichsen

Resilience becomes a must. Actually resilience is an issue for a long time, but with ever-increasing distribution it becomes a must. But how can we implement resilience into our applications? Hystrix, an open-source library developed by Netflix provides a nice starting point. It provides downstream isolation by implementing patterns like timeout, circuit breaker and load shedder. This presentation gives an introduction into Hystrix, providing lots of code examples.

Performance and Fault Tolerance for the Netflix API - QCon Sao Paulo

Ben Christensen

Presented at QCon Sao Paulo on August 4th 2012 (http://qconsp.com/palestrante/ben-christensen) The Netflix API receives over a billion requests a day which translates into multiple billions of calls to underlying systems in the Netflix service-oriented architecture. These requests come from more than 800 different devices ranging from gaming consoles like the PS3, XBox and Wii to set-top boxes, TVs and mobile devices such as Android and iOS. This presentation describes how the Netflix API supports those devices and achieves fault tolerance in a distributed architecture while depending on dozens of systems which can fail at any time. It also explains how a new system design allows each device to optimize API calls to their unique needs and leverage concurrency on the server-side to improve their performance.

Manifesto Netflix: o documento que pode mudar o formato das empresas

FAIR PLAY AD / @VeronicaRRSouza

Manifesto Netflix: o documento que pode mudar o formato das empresas Antes de começar a falar do conteúdo desse manifesto, vale destacar o tom visionário que ele tem (publicado em 01 de agosto de 2009) e que antevê muitas coisas que até hoje não vemos em multinacionais/marcas globais estruturadas, mas ainda engessadas. Outro ponto que vale destaque é o que o "número 2 do Facebook", Sheryl Sandberg disse: “Provavelmente este é o documento mais importante que já saiu do Vale do Silício.” Do que se trata o manifesto Netflix: É um documento meio código de conduta meio manual de cultura organizacional, que traz os valores da empresa e a forma como ela enxerga que seus colaboradores precisam se comportar. Esse manifesto possui 124 telas, mas trouxe aqui os tópicos que mais me chamaram atenção pela ousadia e originalidade: Criatividade é o mais importante: no trabalho processual boas ideias são 2x melhores que a média. Na indústria da criatividade as melhores são até 10x mais; Priorize descobertas ao invés de segurança para os funcionários: empresas de internet geralmente não têm órgãos trabalhistas com leis bem definidas para seus colaboradores (e mesmo assim sempre figuram entre as melhores para se trabalhar) por isso, mostre pra ele que ele pode realizar grandes descobertas; Decisões são tomadas em consenso coletivo: o manifesto prega que geralmente erros ou mal entendidos são problemas de comunicação. Pronto, problema resolvido; Férias ilimitadas: você decide quando volta a trabalhar. E esse empoderamento passado para o colaborador trouxe autonomia e melhores resultados para a empresa. O Netflix orgulhosamente também substituiu todo o aparato burocrático relacionado a custos de viagens com algumas palavras “Haja com as melhores intenções aos interesses do Netflix.” "Somos um time, e não uma família": a ideia é ser um time desportivo profissional e não um monte de crianças na recreação. Entendeu por que o manifesto pode mudar a forma como as empresas são construídas hoje? A contracultura de empresa engessada, que prioriza o invariável e o que rentabiliza deve ser mexido levemente pra trazer ainda mais rentabilidade (isso quando se pode mexer), enquanto que o Netflix prioriza a incerteza, o poder da criatividade e da chance de correção no meio do caminho, e principalmente prioriza a confiança no colaborador, no valor percebido por ele de trabalhar numa empresa que faz a diferença na sociedade e que seu propósito vai de encontro com o dele. Ainda, valoriza o espaço concedido para sua vida pessoal, apesar do trabalho intenso. Claro que pensar que esse modelo de liberdade aplicado para todas as empresas é utopia - e até errado - já que para uma empresa que precisa da criatividade o manifesto é mesmo ideal. Claro que o gesso e o balizamento são essenciais em determinados ramos de atividade mas, até empresas assim podem aprender um pouco com o manifesto. . Redigida por Ivan Alves Nogueira

Self healing data

Uwe Friedrichsen

With the raise of NoSQL databases consistency models that are less strict than ACID transactions became popular again. After the first enthusiasm the developer community became aware that those relaxed consistency models hold some new challenges they never knew about in the ACID world. Fortunately there are some concepts around how to deal with those challenges. This presentation gives a rough introduction into the different consistency models that are available and their characteristics. Then it focusses on two techniques to deal with relaxed consistency. The first one are quorum-based reads and writes which provides a client-side strong consistency model (even if the database only implements eventual consistency). Then CRDTs (Conflict-free Replicated Data Types) are presented. CRDTs are self-stabilizing data structures which are designed for environments with extremely high availability requirements - and thus extremely weak consistency guarantees. Even though as always the majority of the information is on the voice track, I designed the slides in a way that they also provide some useful information without the voice.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf

Paige Cruz

Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack. While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack. I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024 https://alandix.com/academic/papers/synergy2024-epistemic/ As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
