If you are thinking this talk will be littered with Shakespeare references then you will be in for a disappointment. But, if you are hoping this talk will unlock the secrets to some effective patterns for service discovery in your microservice architecture then you are in for a treat! Service discovery can be one of the most difficult techniques when learning micro service patterns, especially if you are a running a containerised system. In this talk I will discuss some of the common patterns for service discovery and how they can be used in your environment, we will also look at a couple of frameworks which do the hard work for you. Key takeaways: What service discovery is and why you need it Introduction to common service discovery patterns Patterns for fault tolerance and high availability Nic Jackson is a software engineering evangelist working for notonthehighstreet.com. www.notonthehighstreet.com

4. Whatwewillcovertoday
» Service discovery
» Server side patterns
» Client side patterns
» Fault tolerance patterns

5. Context
» Services typically need to call one another
» Monolithic applications communicate through language
level or procedural calls
» With SOA services generally run at fixed or well known
locations
» Microservices are easy
» Building Microservice systems are hard
