Kết hợp các mẫu kiến trúc / pattern vào trong một (DDD, Hexagonal, Onion, Clean, CQRS, …)

Trong các bài viết trước, chúng ta đã điểm qua khá nhiều các concept, principle và pattern trong Software Architecture world. Mỗi pattern mang đến cách giải quyết cho những vấn đề khác nhau, vậy câu hỏi đặt ra là liệu chúng ta có thể kết hợp chúng lại để mang đến giải pháp toàn… Continue reading Kết hợp các mẫu kiến trúc / pattern vào trong một (DDD, Hexagonal, Onion, Clean, CQRS, …)

Service Oriented Architecture (SOA)

Trong bài này chúng ta sẽ thảo luận về Service Oriented Architecture (SOA). Tuy là nói về architecture, nhưng tôi tin nó sẽ rất khác so với những bài viết trước khi chúng ta bàn về DDD, Hexagonal hay Event-Drivent Architecture, chúng chỉ nói về cách thức thiết kế và ghép nối các component lại,… Continue reading Service Oriented Architecture (SOA)

Event-Driven Architecture

Event-driven architecture (EDA) là mẫu kiến trúc phần mềm (architecture software pattern) trong đó, về cơ bản, hệ thống được xây dựng xung quanh các thao tác như tạo, khám phá, tiêu thụ và đáp trả lại các sự kiện (event). Hiểu đơn giản hơn, EDA là một dạng kiến trúc phần mềm được xây… Continue reading Event-Driven Architecture

Four Spring Cloud Projects That You Should Be Using

Richard Seroter's Architecture Musings

Since I’ve moved up to the Seattle-area three years ago, there’s been a hole in my life. No longer. The Habit just opened up around the corner from me. I missed that place! While most of the attention (including my own) is on the Charburger, they actually have a pretty deep menu. I thought about that this week when looking at the latest Spring Cloud portfolio. While it’s used millions of times per month by Java developers —and usage grew 137% over the past year alone—Spring Cloud is best known for its Config Server and packaging of NetflixOSS tech. You know, things for service discovery, load balancing, circuit breakers, etc. THEY DESERVE THE GLORY. But there are four other interesting packages that you shouldn’t overlook.

Spring Cloud Stream

It’s no secret that I’m a big fan of this library. It abstracts away all the complexity of dealing with message…

How should you model your event-driven processes?

Richard Seroter's Architecture Musings

During most workdays, I exist in a state of continuous partial attention. I bounce between (planned and unplanned) activities, and accept that I’m often interrupt-driven. While that’s not an ideal state for humans, it’s a great state for our technology systems. Event-driven applications act based on all sorts of triggers: time itself, user-driven actions, system state changes, and much more. Often, these batch-or-realtime, event-driven activities are asynchronous and coordinated in some way. What options do you have for modeling event-driven processes, and what trade-offs do you make with each option?

Option #1 – Single, Deterministic Process

In this scenario, the event handler is monolithic in nature, and any embedded components are purpose-built for the process at hand. Arguably, it’s just a visually modeled code class. While initiated via events, the transition between internal components is pre-determined. The process is typically deployed and updated as a single unit.
