An Introduction To CQRS
An introduction to the CQRS (Command Query Responsibility Segregation) style of application architecture. Also touching on CQS (command query separation), Event Sourcing, Pub-Sub, and a little DDD.
Event Sourcing
Event sourcing is a data persistence technique where all changes to an application's state are stored as a sequence of events. This allows the entire state of the application to be reconstructed by replaying the events in order. Some key benefits of event sourcing include capturing business intent, providing an audit log, and allowing the data to be rebuilt into any data model. However, it also has some drawbacks such as requiring multiple data sources and models, dealing with versioning issues, and potential performance impacts.
Migration microservices to GraphQL
This document discusses migrating a REST API to a GraphQL API. It covers some of the benefits of GraphQL like getting exactly what is needed from the client side, having a rich type system, and being transport agnostic. It provides examples of defining GraphQL types based on a JSON schema and making requests using those types. It also mentions some tools that can help with building and debugging a GraphQL API as well as some precautions to keep in mind during development.
Command Query Responsibility Segregation (CQRS)
This document discusses Command Query Responsibility Segregation (CQRS). It begins with an agenda and overview of why CQRS is used, including for complex domains, separating read and write boundaries, and enabling scalability. It then explains the typical architecture with one object for data access versus CQRS, which separates reads and writes into different objects or services. The document outlines some of the benefits of CQRS like skill set segregation and enabling divergent models. It also notes that CQRS is not a top-level architecture, but can be applied within bounded contexts, and emphasizes that CQRS is simply separating reads from writes rather than implying specific patterns or technologies.
The Good, The Bad and The Ugly of Event Sourcing
In 2009, I first learned about Event Sourcing and Command Query Responsibility Seggregation (CQRS) at a training Greg Young gave in Utrecht, The Netherlands. I remembered to be awed by the scalability and architectural simplicity those styles provided. However, I also remembered the technical complexity that comes with it. In 2012, I was in charge of transitioning a CQRS-based system to Event Sourcing. I knew it would be non-trivial, but boy was I in for a surprise.
So over the last four years I've experienced first-hand how a large group of developers had to deal with the transition. It's a brilliant solution for high-performance or complex business systems, but you need to be aware that this also introduces challenges most people don't tell you about. In this talk, I'd like to share you some of the most powerful benefits of ES, but also show you the flipside of the coin and cover some of the smaller and bigger challenges you'll run into it. Again, I love it and would apply it again without any doubt, but I really want you to understand the trade-offs before you jump on the Event Sourcing train.
How to practice TDD without shooting yourself in the foot
The document discusses best practices for test-driven development (TDD), including that unit tests for code should be fast, isolated, repeatable, and run in any order. It recommends writing tests that initially fail for the expected reason, then implementing just enough code to make the test pass and refactoring code. Tests should have a well-defined boundary and avoid technical names or constants. Example code and additional resources on TDD are also referenced.
O conceito de pesquisa documental
1) A pesquisa documental é uma técnica importante para pesquisas em ciências sociais e humanas que envolve a análise de documentos contemporâneos ou históricos.
2) A pesquisa documental envolve a busca por informações em diversos tipos de documentos para fins de pesquisa, como cartas, filmes, registros e relatórios.
3) Diferente da pesquisa bibliográfica, a pesquisa documental consulta uma variedade maior de fontes além de livros e revistas, como arquivos e outros materiais.
CQRS and what it means for your architecture
A session on the CQRS pattern (Command Query Responsibility Separation) with C# code samples, and a discussion of what it means for your architecture and when and why you should use it. First presented at the Sydney Alt.Net group in June 2016.
Developing event-driven microservices with event sourcing and CQRS (Shanghai)
This is a talk I gave in Shanghai on July 4th 2016
In a microservices architecture, each service has its own database. While this ensures that services are loosely coupled it creates a problem: how do you maintain consistency across services without using 2PC? In this talk you will learn more about these issues and how to solve them by using an event-driven architecture. We will describe how event sourcing and Command Query Responsibility Separation (CQRS) are a great way to realize an event-driven architecture. You will learn about a simple yet powerful approach for building, modern, scalable applications.
PureApplication: Devops and Urbancode
This document discusses how Zurich Insurance was able to deliver DevOps style production values and double performance of their Risk Management Platform using PureApplication and UrbanCode Deploy. PureApplication allowed them to create reusable patterns for deploying the solution components. UrbanCode Deploy provided automated deployment of the patterns and management of the environments. Together, PureApplication and UrbanCode Deploy provided a synergetic solution that rapidly and consistently deployed the overall Risk Management Platform, reducing downtime and speeding up computation times.
Ensuring Software Quality in the cloud
The document discusses testing Docker images to ensure software quality on the cloud. It describes using tools like CTF, Behave, Arquillian Cube, and CE-ARQ to define test scenarios and run smoke tests on images built with Source-to-Image (S2I) to test functionality, parameterization, configuration, and builds. Tests are run locally or in a "TestRunner Pod" on OpenShift using templates, applications, and test classes defined in an Arquillian XML descriptor. References are provided to relevant GitHub repositories.
effective java
Geralmente aplicativos buscam resolver uma única tarefa. Mas conforme o passar do tempo, a aplicação tende a ganhar novas features e otimizações, consequentemente ela tende a crescer. Mais features e mais usuários significam mais código. E quanto mais código você escreve, mais código você precisa manter e reescrever. Nos livros "Effective Java" e "Android programming - pushing limits", Joshua Bloch e Erik Hellman, respectivamente, demonstram boas práticas para o desenvolvimento em Java e na plataforma Android. A idéia é fazer um apanhado das melhores práticas trazidas por estes livros. Detalharei o que deve o que não deve ser feito ao aplicar tais práticas.

Transformacion e innovacion digital Meetup - Application Modernization and Mi...José Román Martín Gil
This document discusses application modernization and migration strategies for moving applications to the cloud. It begins by defining application modernization and migration as focusing on business workloads and digital transformation. It then discusses why modernization is important, including reasons like disruption, embracing digital transformation, and gaining business agility. The document outlines various migration strategies like rehosting, replatforming, refactoring, repurchasing, and retiring applications. It also discusses modern application concepts like better software architecture, streamlining the application lifecycle, and continuous innovation. Finally, it covers cloud-readiness and demonstrates migrating an application to OpenShift through repackaging, deploying with containers, and modernizing the architecture."Paradigm Shifting" Presentation
The document discusses building a "Paradigm Shifting Map" to identify major paradigms that define a solution architecture. It provides examples of paradigms like functional programming, object-oriented, and cloud computing. The author explains how to classify paradigms, detail relevant ones, and create a map with color coding to represent when paradigms were prominent. An example map is shown mapping the evolution of architectures for a "Concept Framework" project from multiple models/tools to a single model with fewer specialties and reduced complexity. The map helped shift paradigms to better meet project goals.
Zap Scanning
This document summarizes a master's thesis that presents a solution for scanning sequences of HTTP requests in the open source penetration testing tool ZAP (Zed Attack Proxy). The thesis documents the analysis, design, and implementation phases of adding multi-step scanning functionality to ZAP. It also explains how different test scenarios were used to verify the functionality. The proposed solution serves as a proof-of-concept that could later be integrated into the publicly available version of ZAP.
Multilanguage Pipelines with Jenkins, Docker and Kubernetes (Oracle Code One ...
Conference session from Oracle Code One San Francisco 2018 - In the brave new world of microservices, the need for polyglot solutions is growing, making it harder to standardize continuous delivery pipelines across many different languages and runtimes. Tasks like compiling, packaging, profiling or verifying software components, are now more diverse and our toolbelt as developers does not cease to grow. Thankfully, there are ways to prescribe and standardize without losing freedom and flexibility. In this talk we will showcase. from a very pragmatic and hands-on point of view, an architectural approach based on real-world project experiences, unleashing the power of Jenkins, Jenkinsfile declarative pipelines, Jenkins libraries, Docker and Kubernetes as the universal runtime platform, for continuously delivering polyglot components at ease.

Quem nunca ouviu falar a celebre frase: Meu gerente e a empresa onde eu trabalho não dão importância se estamos aplicando o padrão XYZ. Para a empresa, o que importa é ter o produto no mercado trazendo monetização para a instituição. Essa afirmação tem sua parcela de verdade. A mudança na forma de pensar não tem que partir de fora para dentro e nem de dentro para fora, o que tem que existir é o entendimento do valor curto, médio e longo prazo que essas práticas vão trazer ao projeto. O time precisa voltar seus olhares também para o seu dia a dia. Pense em algo que é divertido, escalável, fácil de manter, tem legibilidade e é fácilmente testado. Pensou?

Digital Banking in the Cloud: How Citizens Bank Unlocked Their Mainframe
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
