Microservice fundamentals

Understanding the power and complexity of microservice architectures

Topic: System Administration
Sam Newman

Microservices—they’re everywhere! Microservices help organizations achieve autonomy at scale and mix technologies. They can put software in the hands of users faster than other styles of architecture and can unlock opportunities to scale applications or handle security concerns in different ways. But without a good understanding of what microservices actually are and the benefits they offer, you may not reap all of these potential benefits and—worse—could end up adding complexity and fragility where it could have been avoided.

Join expert Sam Newman to gain a firm understanding of microservice architectures, the advantages to using microservices, and most importantly, all the problems they can create. Along the way, you’ll compare microservices to alternative system decomposition techniques to find out what makes microservices different. By the time you're through, you'll better understand if microservices are right for you and if so, how to go about adopting them.

What you'll learn-and how you can apply it

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

  • Exactly what microservices are and the power they bring
  • How to get the most out of microservices architectures and avoid common pitfalls
  • When using microservices is sensible (and when it's not)

And you’ll be able to:

  • Distinguish between microservices and other forms of system decomposition and decide when to choose one over the others
  • Explain why microservice architectures may be useful (or not)
  • Determine if you should use microservices for your own project

This training course is for you because...

  • You're considering adopting a microservice architecture.
  • You want a firm foundation in one of the most-talked-about technology trends of recent years (while avoiding getting swept up in the hype).
  • You want to become more of a technical leader and need to better understand how to determine the right solutions for your problems.


  • Familiarity with basic programming concepts
