This document discusses CQRS and event sourcing patterns for Java developers. It begins with an overview of classical monolithic architectures versus modern microservice architectures. It then contrasts CRUD with CQRS, explaining that CQRS separates reads from writes by using commands for writes and queries for reads. Events evolve from commands and represent things that occurred in the past. The document provides an example implementation using the Lagom framework that demonstrates separating the write side from the read side and persisting events. It emphasizes that with this approach, all state changes are stored as events and the current state can be recreated by replaying events. The document encourages the use of Lagom due to benefits like asynchronous programming, developer productivity, and production readiness.

Speakers: Kevin Hoffman; Advisory Solutions Architect, Pivotal & Chris Umbel; Advisory Architect, Pivotal
With the advent of ASP.NET Core, developers can now build cross-platform microservices in .NET. We can build services on the Mac, Windows, or Linux and deploy anywhere--most importantly to the cloud.
In this session we'll talk about Cloud Native .NET, building .NET microservices, and deploying them to the cloud. We'll build services that participate in a robust ecosystem by consuming OSS servers such as Spring Cloud Configuration Server and Eureka. We'll also show how these .NET microservices can take advantage of circuit breakers and be automatically deployed to the cloud via CI/CD pipelines.
Apache Kafka and ksqlDB in Action: Let's Build a Streaming Data Pipeline! (Ro...confluent
Have you ever thought that you needed to be a programmer to do stream processing and build streaming data pipelines? Think again! Apache Kafka is a distributed, scalable, and fault-tolerant streaming platform, providing low-latency pub-sub messaging coupled with native storage and stream processing capabilities. Integrating Kafka with RDBMS, NoSQL, and object stores is simple with Kafka Connect, which is part of Apache Kafka. ksqlDB is the source-available SQL streaming engine for Apache Kafka and makes it possible to build stream processing applications at scale, written using a familiar SQL interface.
In this talk, we’ll explain the architectural reasoning for Apache Kafka and the benefits of real-time integration, and we’ll build a streaming data pipeline using nothing but our bare hands, Kafka Connect, and ksqlDB.
Gasp as we filter events in real-time! Be amazed at how we can enrich streams of data with data from RDBMS! Be astonished at the power of streaming aggregates for anomaly detection!

Slides for my talk event-sourced architectures with Akka. Discusses Akka Persistence as mechanism to do event-sourcing. Presented at Javaone 2014 and Jfokus 2015.
As businesses grow, so does the complexity of their software. New features, new models, and new background processes all continue to be added. . .and developers struggle to make sense of it all. Yet the end user demands a swift and functional experience when interacting with your application. It is paramount to be open to alternative patterns that help tame complex, high-demand services. Two such patterns are command-query responsibility segregation (CQRS) and event sourcing (ES).
Command-query responsibility segregation is an architectural pattern for user-facing applications that extends from the now standard Model-View-Controller (MVC) pattern and is an alternative to the CRUD pattern. At its core, CQRS is about changing how we think of and work with our data by introducing two types of models: all user actions become commands, and a read-only query model powers our views. Commands and queries are logistically separated, providing additional decoupling of our application. CQRS also calls for changes in how we store and structure our data.
Enter event sourcing. Instead of persisting the current state of our domain objects or entities, we record historical events about our data. The key advantage is that we can examine our application data at any point in time, rather than just the current state. This pattern changes how we persist and process our data but is surprisingly efficient.
While each of the two patterns can be used exclusively, they complement each other beautifully and facilitate the construction of decoupled, scalable applications or individual services. Stephen Pember explores the fundamentals of each pattern and offers several examples and demonstration code to show how one might actually go about implementing CQRS and ES. Steve discusses task-based UIs and domain-driven design as he outlines some of the advantages—and challenges—that ThirdChannel has seen when developing systems using CQRS and ES over the past year.
Akka persistence == event sourcing in 30 minutesKonrad Malawski
Akka 2.3 introduces akka-persistence, a wonderful way of implementing event-sourced applications. Let's give it a shot and see how DDD and Akka are a match made in heaven :-)
CQRS and Event Sourcing, An Alternative Architecture for DDDDennis Doomen
Most of us will be familiar with the standard 3- or 4-layer architecture you often see in larger enterprise systems. Some are already practicing Domain Driven Design and work together with the business to clarify the domain concepts. Perhaps you’ve noticed that is difficult to get the intention of the 'verbs' from that domain into this standard architecture. If performance is an important requirement as well, then you might have discovered that an Object-Relational Mapper and a relational database are not always the best solution.
One of the main reasons for this is the fact that the interests of a consistent domain that takes into account the many business rules, and those of data reporting and presentation are conflicting. That’s why Betrand Meyer introduced the Command Query Separation principle.
An architecture based on this principle combined with the Event Sourcing concept provides the ideal architecture for building high-performance systems designed using DDD. Well-known bloggers like Udi Dahan and Greg Young have already spent quite a lot of of posts on this, and this year’s Developer Days had some coverage as well.
But how do you build such a system with the. NET framework? Is it really as complex as some claim, or is just different work?
Stay productive while slicing up the monolith Markus Eisele
DevNexus 2017
Microservices-based architectures are en-vogue. The last couple of
years we have learned how the thought-leaders implement them, and
every other week we have heard about how containers and
Platform-as-a-Service offerings make them ultimately happen.
The problem is that the developers are almost forgotten and left alone
with provisioning and continuous delivery systems, containers and
resource schedulers, and frameworks and patterns to help slice
existing monoliths. How can we get back in control and efficiently
develop them without having to provision complete production-like
environments locally, by hand?
All the new buzzwords, frameworks, and hyped tools have made us forget
ourselves—Java developers–and what it means to be productive and have
fun building systems. The problem that we set out to solve is: how can
we run real-world Microservices-based systems on our local development
machines, managing provisioning, and orchestration of potentially
hundreds of services directly from a single command line tool, without
sacrificing productivity enablers like hot code reloading and instant
turnaround time?
During this talk, you’ll experience first-hand how much fun it can be
to develop large-scale Microservices-based systems. You will learn a
lot about what it takes to fail fast and recover and truly understand
the power of a fully integrated Microservices development environment.

Sustainable Software Architecture - Open Tour DACH '22Markus Eisele
Rolling into summer in Europe, still recovering from the last two years another global thread pops back into people's minds. Extreme heat waves followed by severe weather phenomena remind all of us that climate change is a reality. As a father of two wonderful children that hopefully live beyond 2090, I was wondering what impact software architecture has on global warming and climate change and how I can build better and more sustainable solutions. This presentation and demo will provide you with tools, best practices and metrics (executives love numbers and dashboards) to prove the investment in Containers, OpenShift and a DevOps approach has a tangible return.

Stateful on Stateless - The Future of Applications in the CloudMarkus Eisele
Most developers building applications on top of Kubernetes are still mainly relying on stateless protocols and design. The problem is that focusing exclusively on a stateless design ignores the hardest part in distributed systems: managing state—your data.
The challenge is not designing and implementing the services themselves, but managing the space in between the services: data consistency guarantees, reliable communication, data replication and failover, component failure detection and recovery, sharding, routing, consensus algorithms and so on.
Kubernetes and Akka work well together since each being responsible for a different layer and function in the application stack. Kubernetes allows for coarse-grained container-level management of resilience and scalability. Akka allows for fine-grained entity-level management of resilience and scalability. This talk demonstrates how the two play together to deliver the future of stateful applications in the cloud.

Java in the Age of Containers and ServerlessMarkus Eisele
Java in 2019 was predicted to be business as usual by many. We have seen new Java releases coming out as planned, AdoptOpenJDK became the main trustful source of binaries and Oracle fighting for the trademark again by preventing the use of javax as namespace.
Everything looks like it would be a silent year for Java. But one thing seems also obvious. Java's popularity is not gaining any more traction. New language features keep it up to date but people are getting more selective when it comes to implementation choices. Especially in the age of containers and cloud infrastructures. How will Java continue to fit in? What are the advantages and what needs to be done?

Migrating from Java EE to cloud-native Reactive systemsMarkus Eisele

The world is moving from a model where data sits at rest, waiting for people to make requests of it, to where data is constantly moving and streams of data flow to and from devices with or without human interaction. Decisions need to be made based on these streams of data in real-time, models need to be updated, and intelligence needs to be gathered. In this context, our old-fashioned approach of CRUD REST APIs serving CRUD database calls just doesn't cut it. It's time we moved to a stream-centric view of the world.

The world is moving from a model where data sits at rest, waiting for people to make requests of it, to where data is constantly moving, streams of data flow to and from devices with or without human interaction. Decisions need to be made based on these streams of data in real time, models need to be updated, intelligence needs to be learned. And our old-fashioned approach of CRUD REST APIs serving CRUD database calls just doesn't cut it, it's trying to fit a square peg into a round hole. It's time we moved to a stream-centric view of the world.
This talk will look at how Reactive Streams is shaping the future of Jakarta EE. I'll talk about some Reactive Streams based specifications that we're currently working on in the JDK, MicroProfile and Jakarta EE communities, as well as some potential big ideas to transform the way developers write their applications, such as event sourcing and CQRS, that Jakarta EE will likely adopt in future. We'll take a look at a hypothetical future Jakarta EE, at what a typical service will look like when streaming is embraced, and get a glimpse of how Jakarta EE can lead the world in standards for Reactive systems.
Reactive Integrations - Caveats and bumps in the road explained Markus Eisele
Understand the different approaches to integrate fast data and streams based frameworks into your legacy applications and learn about the advantages, disadvantages, caveats, and bumps in the road.
Architecting for failure - Why are distributed systems hard?Markus Eisele
Devnexus 2017
As we architect our systems for greater demands, scale, uptime, and performance, the hardest thing to control becomes the environment in which we deploy and the subtle but crucial interactions between complicated systems. And microservices obviously are the way to go forward with those complicated systems. But what makes it so hard to build them? And why should you embrace failure instead of doing what we can do best: Preventing failure. This talk introduces you to the problem domain of a distributed system which consists of a couple of microservices. It shows how to build, deploy and orchestrate the chaos and introduces you to a couple of patterns to prevent and compensate failure.
Nine Neins - where Java EE will never take youMarkus Eisele
Virtual JUG Session: http://www.meetup.com/virtualJUG/events/232052100/
With Microservices taking the software industry by storm, classical Enterprises are forced to re-think what they’ve been doing for almost a decade. It’s not the first time, that technology shocked the well-oiled machine to it’s core. We’ve seen software design paradigms changing over time and also project management methodologies evolving. Old hands might see this as another wave that will gently find it’s way to the shore of daily business. But this time it looks like the influence is bigger than anything we’ve seen before. And the interesting part is, that microservices aren’t new from the core. Talking about compartmentalization and introducing modules belongs to the core skills of architects. Our industry also learned about how to couple services and build them around organizational capabilities.
The really new part in microservices based architectures is the way how truly independent services are distributed and connected back together. Building an individual service is easy with all technologies. Building a system out of many is the real challenge because it introduces us to the problem space of distributed systems. And the difference to classical, centralized infrastructures couldn’t be bigger. There are very little concepts from the old world which still fit into a modern architecture.
And there are more differences between Java EE and distributed and reactive systems. For example, APIs are inherently synchronous, so most Java EE app servers have to scale by adding thread pools as so many things are blocking on I/O (remote JDBC calls, JTA calls, JNDI look ups, even JMS has a lot of synchronous parts). As we know adding thread pools doesn't get you too far in terms of scalability.
This talk is going to explore the nine most important differences between classical middleware and distributed, reactive microservices architectures and explains in which cases the distributed approach takes you, where Java EE never would.
Taking the friction out of microservice frameworks with LagomMarkus Eisele
Lagom is a new framework for Java designed with microservices in mind. It aims to simplify the process of building microservice-based systems that communicate asynchronously, self-heal, scale elastically and remain responsive under load and under failure.
Many of the challenges of microservices are caused by the fact we use tools designed without them in mind. So, how can a framework made to build systems composed of microservices from the start offer us a better solution? Because Lagom is a tool that is highly opinionated and explicitly designed to make development and production with microservices easy, it brings back all the fun and productivity into programming while still enabling you to build a reactive, distributed, highly scalable and rock solid application.
By the end of this presentation, you'll have experienced first hand how creating systems of microservices on the JVM using Lagom is dead-simple, intuitive, frictionless and a lot of fun! And we’ll ask whether reactive microservices are potentially so much better than, for example, Java EE?
