This document provides recommendations for organizations considering migrating to the public cloud. It addresses common questions around security, costs, compliance, and architecture decisions. Key recommendations include: - Use threat modeling to prioritize security and consider boundaries and openness. Cloud can improve security when done right. - Be aware of higher initial costs of cloud and factor them into budgets. Speed and agility, not just cost savings, should motivate cloud adoption. - Leverage platform as a service (PaaS) capabilities to simplify designs while limiting vendor lock-in. Start with infrastructure as a service (IaaS) and shift to PaaS over time. - Consider cross-region disaster recovery needs based on compliance and

There are many design patterns for building microservices, and most of them are wrong. Actually, that is not true. The fundamental objectives for implementing microservice systems are speed and agility. Speed, of course, is how quickly you can get things done. Regardless of what design patterns you use, if you can quickly build, fix, enhance, and rapidly evolve your microservices, you are heading in the right direction. Agility is the flexibility to move rapidly across the entire development lifecycle while living happily in production. But we can always do better. Right? That is what this talk is about. We will take a look at some of the more common microservice design patterns. And we will compare them to some of the alternatives. For example, what is the more common microlith design pattern, and how getting serious about loose coupling guides the evolution to ways that increase your speed and agility? We will also look at why it is micro at the code level and the data level. Finally, we will cover some practical guidelines, such as why your microservices should do the least amount of work while your users are waiting and techniques for doing that.

1. The document discusses using speech acts as the basis for building immutable conversational interfaces and applications. 2. Speech acts model conversations as sequences of immutable events that narrow responses. This approach can be used to build various interfaces like chatbots, administrative tools, and mobile applications. 3. Experiments can be run by assigning users to different versions of state machine definitions that define how conversations branch based on inputs. This facilitates A/B testing and machine learning to optimize interfaces.

Slides from the talk on 13th of November at the DDD Belgium Meetup in Gent/Brussels held together with Martin Schimak.

Event Sourcing By Touraj Ebrahimi. Senior Java Developer and Java Architect. github: toraj58 bitbucket: toraj58 twitter: @toraj58 youtube channel: https://www.youtube.com/channel/UCcLcw6sTk_8G6EgfBr0E5uA

This presentation, given on the Software Architecture course at the University of Brunel, discusses the interplay between architecture and design. How the designer and architect are really different roles and ones that often have competing goals.

Event Driven Architecture (EDA) is presented as an alternative to Service Oriented Architecture (SOA). In EDA, business capabilities are defined which own parts of the system and communicate through shared communication channels using events, commands, and documents as messages. Examples are provided of a simple event and command message format. Key aspects of EDA include eventual consistency, idempotency, and ability to replay messages. The presentation concludes with discussing some advantages of EDA like improved scalability and isolation, and technologies used in one company's EDA infrastructure like RabbitMQ and Reactive Extensions.

A revised and extended version that I gave at Saturn 2018. The services in a microservice architecture must be loosely coupled and so cannot share database tables. What’s more, two phase commit (a.k.a. a distributed transaction) is not a viable option for modern applications. Consequently, a microservices application must use the Saga pattern, which maintains data consistency using a series of local transactions. In this presentation, you will learn how sagas work and how they differ from traditional transactions. We describe how to use sagas to develop business logic in a microservices application. You will learn effective techniques for orchestrating sagas and how to use messaging for reliability. We will describe the design of a saga framework for Java and show a sample application.

- The document discusses breaking event chains, decentralizing control, and alternatives to workflow engines for orchestrating microservices. It argues that events can decrease coupling but also increase it, and that central control should be avoided but important long-running capabilities still need ownership. Lightweight workflow engines are presented as a better alternative to DIY orchestration since they address hard problems and can run decentralized.

This document provides an introduction to microservices, including: - Microservices are small, independently deployable services that work together and are modeled around business domains. - They allow for independent scaling, technology diversity, and enable resiliency through failure design. - Implementing microservices requires automation, high cohesion, loose coupling, and stable APIs. Identifying service boundaries and designing for orchestration and data management are also important aspects of microservices design. - Microservices are not an end goal but a means to solve problems of scale; they must be adopted judiciously based on an organization's needs.

With popular poster children such as Netflix and Amazon, Microservices based architecture seems to be the killer approach to 21st century architectures. But are they only for Hollywood Coders pioneering on the bleeding edge of our profession? Or are they ready to be used for your projects and your customers? I will go over the benefits, but more so the pitfalls, of using a Microservices based architecture. What impact does it have on your organization, your applications, on dealing with scale and failures, and how do you prevent your landscape from becoming an unmaintainable nightmare.

This document discusses orchestrating microservices using event-driven architectures and process managers. It describes how independent microservices can collaborate by publishing domain events to which other services subscribe. While this loose coupling is beneficial, long-running processes require persistent state management. The document recommends using a process manager to handle event-command transformation and state for long-running flows, providing visibility, versioning, and other capabilities. It warns against creating monolithic workflows across microservices and advocates defining local flows within bounded contexts.

The document discusses the CAP theorem which states that it is impossible for a distributed computer system to simultaneously provide consistency, availability, and partition tolerance. It defines these terms and explores how different systems address the tradeoffs. Consistency means all nodes see the same data at the same time. Availability means every request results in a response. Partition tolerance means the system continues operating despite network failures. The CAP theorem says a system can only choose two of these properties. The document discusses how different types of systems, like CP and AP systems, handle partitions and trade off consistency and availability. It also notes the CAP theorem is more nuanced in reality with choices made at fine granularity within systems.

Presented in Pittsburgh, PA for Abstractions.io in August, 2016. "The greater your adoption success, the greater your retirement pain." The number of APIs has exploded and will continue growing as more teams adopt microservices. In my time at Amazon my team of eight owned hundreds of microservices, covering every possible life cycle phase. Two of our services were more than a decade old. These lingered despite several interface iterations launched to cover alternative use-cases, multiple ownership changes, and funded retirement initiatives. The reason was simple: hundreds of internal and external clients had a dependency on these services. A coordinated migration effort was nearly impossible to prioritize across the whole of Amazon and integrated third-party merchant software. To make matters worse, many of our clients were as old as the services themselves. Several were owned by teams that had long since forgotten about them. We were all victims of these successful services. As I took over as manager of the team I knew that failure to retire these services in the next year would be a critical blow to our system scalability in Q4. Failure was not an option. I was hellbent on hitting the power switch. Every service owner will eventually encounter this problem. Few want to talk about it. In this session I'll elaborate on the challenges facing service owners, my approach to solving them, the impact of our success, and the lessons learned. I'll share the highs and lows - smooth migrations, and the pain of scream test victims. It is my hope that an attendee will be able to learn from these experiences and succeed in their own retirement efforts.

A journey of a FinTech application into the cloud, starting as a monolith and growing to MicroServices. Why going functional is so good for finance technology, and how Scala helped us build a better application.

Gabriele Pividori presents to us the importance of communication within Domain-Driven Design, how the Ubiquitous Language can aid our software designs and the value the Aggregate pattern can bring.

The principles of CQRS is very simple. Separate Reads from Writes. Although when you try to implement it in you can face many technical and functional problems. This presentation starts from very simple architecture and while business requirements are added we consider other architecture ending with a CQRS + DDD + ES one.

Christian Posta is a principal middleware specialist and architect who has worked with large microservices architectures. He discusses why companies are moving to microservices and cloud platforms like Kubernetes and OpenShift. He covers characteristics of microservices like small autonomous teams and decentralized decision making. Posta also discusses breaking applications into independent services, shedding dependencies between teams, and using contracts and APIs for communication between services.

The document discusses transitioning from a monolithic architecture to microservices architecture for an IoT cloud platform. Some key points include: - The goals of enabling scalability, supporting new markets, and innovation. - Moving to a microservices architecture can help with scalability, fault tolerance, and independent deployability compared to a monolith. - Organizational structure should also transition from function-based to product-based to align with the architecture. - Technical considerations in building microservices include service interfaces, data management, fault tolerance, and DevOps practices.

This presentation covers general engineering and organizational principles for microservices, with 11 specific topics for best practices.

Talk given by David Lucey, Systems Engineering Architect at Salesforce, at Open Network Users Group in May 2016 “Livestock, not Pets.” We’ve all heard the phrase, but it seems to be so much harder in practice. It’s even worse when applications are developed over decades. Well, the Salesforce application suite has been developed over decades, with a massive number of products, features, and offerings within its own ecosystem. Come see how Salesforce wrangles that livestock and handles their scale of infrastructure at a high velocity – all while maintaining their high level of security.

The document discusses Christian Posta's journey with microservices architectures. It begins by explaining why organizations are moving to microservices and defines microservices. It then covers related topics like cloud platforms, container technologies like Kubernetes and OpenShift, benefits and drawbacks of microservices, and tools for developing microservices like Docker, Kubernetes, OpenShift, and Camel.

CPU and RAM costs continue to plummet. Multi-core systems are ubiquitous. Writing code is easier than it has ever been. Why, then, is it still so darn hard to make a scalable system?

This presentation explored the importance of service management in the cloud and explore what is needed to build an operating model for the governance, assurance, and day to day operation of cloud services.

The document discusses the value of next generation managed services which leverage professional, DevOps, and managed security services to provide intelligent operations and automation through a single billing structure. This allows the managed services provider to be a strategic partner, continuously improving their clients' organizations by reducing costs through efficiency and automation while increasing speed to market.

“ The Microservices architecture has many appealing qualities, but the road towards it has painful traps for the unwary. This book will help you figure out if this path is for you, and how to avoid those traps on your journey.” —Martin Fowler Chief Scientist, ThoughtWorks

For the past couple of years it seems that Microservices is all the rage. We want to use Microservices, we want to decompose into Microservices and we want Microservices to be a part of our world. While modern tools and platforms such as Docker, Kubernetes, Service Mesh and the public cloud help in implementing and maintaining such systems, the reality is that many fail even before the first line of code was written. This can happen for many reasons; Perhaps you chose a Microservices architecture for the wrong reasons? Maybe the organization wasn't ready for it? Or just possibly - the proposed architecture didn't embrace the true meaning of Microservices? As the CTO of a software services company I get tackle these questions a lot. Join me in this session as I provide my perspective on transitioning from Monolith to Microservices through lessons learned in the real world, while architecting and implementing multiple Microservices based software systems at various customers.

The document outlines an agenda for a microservices workshop. It is split into four sessions over half a day covering topics such as why use a microservices architecture, principles and constraints of microservices, splitting services, integration strategies, deployment considerations and more. There will be breaks between the sessions.

Blockchain technology is poised for widespread adoption. AWS is working with financial institutions and blockchain providers to further innovation. AWS provides services like CloudTrail, CloudFormation, S3 and VPC that can be used to build robust blockchain solutions globally at scale, whether for public or private blockchains. PwC has experience delivering blockchain proofs-of-concept, pilots and production systems for insurance claims management and asset distribution using these AWS services. Future blockchain use cases may include identity management, utilities, healthcare and energy.
