Description

Outline

Characteristics of an Agile architecture

Conway’s law: How agility and architecture interact

Validating your architecture with fitness functions

Domain modeling

DDD basics: Bounded contexts, aggregates, entities
Agents (UI)

Working with stories

User goals
The system metaphor
Creating stories
Narrowing and splitting

Hands-on exercise: Problem statements and story development

Orchestrated (declarative) systems

Design by coding

TDD
BDD: Given, when, then
DbC: Demo
A quick introduction to mob programming

Hands-on exercise: Creating declarative APIs with DbC

Choreographed systems: Reactive architectures

Event storming

Demo
Hands-on exercise: Creating orchestrated or reactive systems

Adaptive architectural patterns

Structured monolith
Microkernel
Message based
Microservices

Prerequisite knowledge

A basic understanding of computer systems

What you'll learn

By the end of this two-day training course, you'll understand:

How to build architectures that support constant change from business and disruptive technologies
How architecture aligns with company structure and processes
How to analyze business problems to discover architectural characteristics
How to define and refine effective user stories and extract architectural elements from them
How to develop a domain-focused architecture that stays coherent in the face of change

And you'll be able to:

Choose appropriate architectural patterns based on business requirements and evolvability
Create an architecture in incremental steps as you discover new requirements rather than as a single up-front process
Optimize that architecture so that it can evolve over time to accommodate changing requirements
Create and size high-quality user stories and build an architecture around these stories
Use mob programming, domain-driven design (DDD), event storming, design by coding

Allen Holub is one of the country’s foremost software architects and Agile-transformation consultants. Allen speaks internationally about all things Agile and software architecture and provides in-house training and consulting in those areas. He’s also an expert-level programmer, specializing in Swift, Java, and Web 2.0 applications and microservices. Allen can build highly dynamic websites (along the lines of Gmail) from front to back: both the frontend code—JavaScript, JQuery, Angular, HTML5, and CSS3—that runs in the browser and the backend code—Java, PHP, MySQL, Ruby, Mongo, C++, ZeroMQ, and EC2—that runs either on your server or in the cloud. Allen is widely published. His works include 10 books, hundreds of articles in publications ranging from Dr. Dobb’s Journal to IBM DeveloperWorks, and video classes for Agilitry.com (Agility with Allen), Pluralsight (Swift in Depth, Picturing Architecture, Object-Oriented Design), O’Reilly (Design Patterns in the Real World), and Lynda/LinkedIn.
