Microservices are all the rage at the moment, but many people focus on what they look like and how they work once you’ve got them. Suppose your organization has a very different type of architecture, however, how do you move from one to the other?

Join Sam Newman, author of Building Microservices, for an in-depth exploration into how to go about breaking down monolithic systems into microservices. Sam will cut through the buzzwords and be honest about the pros and cons of adopting an architecture that might be radically different from what you have now. By the end of this course, you’ll have a solid grasp of the principles and a concrete set of tools for breaking apart your own systems.

What you’ll learn—and how you can apply it

By the end of this live, online course, you’ll understand:

  • What microservices are, and whether or not they’re right for you
  • How to structure a transition from a monolithic system to microservices
  • How to find boundaries for new services
  • How to identify potential risks and manage outcomes

This course is for you if:

  • You’re a CTO, architect, or tech lead who wants to understand whether microservices are the right choice for your organization and how to take advantage of them
  • You’re a developer looking for help to break down your monolithic systems
  • You want advice on how to implement a sane, balanced approach to moving to microservices

Prerequisites:

  • A good understanding of your current system architecture is very useful
  • Some knowledge of microservices is useful, but not essential
