Chapter 6. Designing for robustness

 

This chapter covers

  • Communicating robustly between microservices
  • Letting the calling side take responsibility for robustness in the face of failure
  • Rolling back versus rolling forward
  • Implementing robust communication

This chapter introduces strategies for making a system of microservices robust in the face of failures. In general, whenever one microservice communicates with another microservice, the communication may fail. In this chapter, you’ll learn about and implement some patterns for dealing with such failures. The strategies are fairly simple, yet they’ll make the overall system much more robust.
