This is the slide deck from my keynote at the EA User Event in Brussels, September 2015. Micro-services and micro-services architecture are the next hype in software development. Websites and blogs are full of introducing posts, the first books are being written and the first conferences organized. There’s big promises of scalability, flexibility and replaceability of individual elements in your landscape. However, when you are knee deep in the mud as a software architect at an insurance, it is very hard to find help on how to design applications and components in a micro-services architecture. During this talk Sander will show how he used Enterprise Architect to model the micro services architecture, and will explain the difficulties and the lessons learned, using many real-life examples.

We change a monolithic system only when we have no other choice. Traditional enterprise systems are tightly-coupled; all-in-one, all-or-nothing, difficult to scale, difficult to understand and difficult to maintain. Rather than swiftly capture opportunity, we ponder if it’s really worth it—is it worth upsetting the delicate balance of the house of cards we call our enterprise system? Often the opportunity quickly disappears, captured by a faster company. Some people have started calling this “Getting Ubered”. So what can you do about it? Talking about Microservices is one thing, but how can your organization start taking action to address this issue? In this webinar by battle-hardened Enterprise Advocate, Kevin Webber, we walk through the 6 key concepts to understand as a guide for taking action: 1. Domain Driven Design (DDD) 2. Asynchronous messaging 3. API management 4. Dependency management 5. CQRS & event sourcing 6. Transactions & ordering Reactive Platform has what you need to breath new life into your legacy system with a new Microservices-based approach.

Microservices and microservices architecture are the next hype in software development. Websites and blogs are full of introducing posts, the first books are being written and the first conferences organized. There’s big promises of scalability, flexibility and replaceability of individual elements in your landscape. However, when you are knee deep in the mud as a software architect at an insurance, it is very hard to find help on how to design applications and components in a microservices architecture. During this talk Sander Hoogendoorn, discusses the long and winding road the insurance company where he’s acting as the lead software architect has taken to implement their business processes in a microservices landscape. Sander will show how this company is modeling requirements in a microservices landscape using smart use cases, and will explain the difficulties and the lessons learned, using many real-life examples.

Organisations are building their applications around microservice architectures because of the flexibility, speed of delivery, and maintainability they deliver. Want to try out MongoDB on your laptop? Execute a single command and you have a lightweight, self-contained sandbox; another command removes all trace when you're done. Need an identical copy of your application stack in multiple environments? Build your own container image and then your entire development, test, operations, and support teams can launch an identical clone environment. Containers are revolutionizing the entire software lifecycle: from the earliest technical experiments and proofs of concept through development, test, deployment, and support. Orchestration tools manage how multiple containers are created, upgraded and made highly available. Orchestration also controls how containers are connected to build sophisticated applications from multiple, microservice containers. This presentation introduces you to technologies such as Docker, Kubernetes & Kafka which are driving the microservices revolution. Learn about containers and orchestration – and most importantly how to exploit them for stateful services such as MongoDB.

Software application development and delivery often involves multiple development, infrastructure and operations teams, each with their own preferred “tools of the trade” for building, testing and deploying code changes For years, virtualization and cloud technologies have provided agile, on-demand infrastructure. The advent of Microservices promises even more agility– but what is required to take advantage of Microservices? Join Electric Cloud CTO Anders Wallgren and Trace3 Principal Consultant - DevOps Marc Hornbeek as they discuss what is required to: - Overcome culture and architecture challenges created when decomposing monolithic applications into Microservices-based applications. - Coordinate integration, testing, monitoring, packaging, release approval and deployment of Microservices-based applications over elastic infrastructures - Create a controlled and auditable delivery pipeline to support Microservices-based application. - Prepare for “future” applications, pipelines and patterns.

In this talk we share our experiences developing and deploying a microservices-based application. You will learn about the distributed data management challenges that arise in a microservices architecture. We will describe how we solved them using event sourcing to reliably publish events that drive eventually consistent workflows and pdate CQRS-based views. You will also learn how we build and deploy the application using a Jenkins-based deployment pipeline that creates Docker images that run on Amazon EC2. This talk was given at the Berlin Microxchg conference and the Munich microservices meetup.

Gilt, a billion dollar e-commerce company, implemented a sophisticated microservices architecture on AWS to handle millions of customers visiting their site at noon every day. The microservices architecture pattern enables independent service scaling, faster deployments, better fault isolation, and graceful degradation. In this session, Derek Chiles, AWS solutions architect, will review best practices and recommended architectures for deploying microservices on AWS. Adrian Trenaman, SVP of engineering at Gilt, will share Gilt's experiences and lessons learned during their evolution from a single monolithic Rails application in a traditional data center to more than 300 Scala/Java microservices deployed in the cloud.

The Project Management Process - Week 11 Contemporary Issues

Craig Brown

One of the upsides of Microservices is the ability to deploy often,at arbitrary schedules, and independently of other services, instead of requiring synchronized deployments happening on a fixed time. But to really leverage this advantage, we need fast, efficient, and reliable deployment processes. That's one of the value propositions of Containers in general, and Docker in particular. Docker offers a new, lightweight approach to application portability.It can build applications using easy-to-write, repeatable, efficient recipes; then it can ship them across environments using a common container format; and it can run them within isolated namespaces which abstract the operating environment, independently of the distribution,versions, network setup, and other details of this environment. But Docker can do way more than deploy your apps. Docker also enables you to generalize Microservices principles and apply them on operational tasks like logging, remote access, backups, and troubleshooting.This decoupling results in independent, smaller, simpler moving parts.

A Gentle Introduction To Agile

Michael Sahota

You’ve been hearing about Microservices for months, and probably have taken a look about 12-factor and cloud-native apps too. But there’s a myriad of different frameworks and tools that you can use to craft your software and join the pieces together into a Microservices Architecture. You want to use the best tool for the job, and you need a hassle-free DevOps pipeline to orchestrate and deploy all of them. Burr explains how you can combine a lot of different technologies and tools that will open your eyes for the huge possibilities that Microservices can enable you to achieve. Have it all: containers, Docker, Vert.x, Wildfly Swarm, Spring Boot, NodeJS, .NET, OpenShift, Jenkins, Kubernetes and perhaps much more.

Continuous delivery has been a driving force behind software development, testing and deployment for years, and CI/CD best-practices are evolving with the advent of new technologies like Kubernetes and Istio. Progressive delivery, a term coined by James Governor, Redmonk, is a new approach to continuous delivery that includes “a new basket of skills and technologies… Such as canarying, feature flags, [and] A/B testing at scale”. In this webinar we will cover how to use GitOps workflows with canary releases and traffic mirroring to realize progressive delivery how to use Weaveworks Flagger to automate canary releases and visualize the results with Aspen Mesh

QConSF 2016 Abstract: By embracing the tension between order and chaos and applying a healthy mix of discipline and surrender Netflix reliably operates microservices in the cloud at scale. But every lesson learned and solution developed over the last seven years was born out of pain for us and our customers. Even today we remain vigilant as we evolve our service architecture. For those just starting the microservices journey these lessons and solutions provide a blueprint for success. In this talk we’ll explore the chaotic and vibrant world of microservices at Netflix. We’ll start with the basics - the anatomy of a microservice, the challenges around distributed systems, and the benefits realized when integrated operational practices and technical solutions are properly leveraged. Then we’ll build on that foundation exploring the cultural, architectural, and operational methods that lead to microservice mastery.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.
