Who is this presentation for?

  • Software architects and software engineers

Prerequisite knowledge

  • A basic understanding of microservices

What you'll learn

  • Explore various ways that microservices can communicate
  • Learn how to solve the problems inherent in orchestrated systems using choreography

Description

Choreographed microservices talk to each other asynchronously, blindly broadcasting notifications into a service cloud. Those notifications are handled by whatever client services are interested. These systems eliminate many of the problems associated with orchestrated systems (which work more like synchronous function calls) and are typically much faster than orchestrated systems, but they have their own idiosyncrasies and implementation challenges.

Allen Holub explores the inherent problems in orchestrated systems and explains how choreography can solve those problems. Allen outlines three approaches to choreography: HTTP based, pub/sub messaging based, and brokerless swarming systems. He also details appropriate messaging architectures and frameworks and shares several practical examples.

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.

How Microservices can be used in large scale industrial software systems (which are predominantly C++, windows, COM, controlling lot of hardware)?

Do microservices have to be associated with web environment, Java? How to develop/deploy in languages like C++, C#, Python? What frameworks are available?

How the microservices can work together with existing layered orchestrated architecture?
