Everyone's talking about microservices, but few have used them in anger. They haven't given any real thought to best practices around building and deploying them. In this talk, we'll highlight many of the mistakes we've seen people make when building a microservices architecture. We'll discuss:

• When microservices are appropriate, and where to draw the lines between services.
• Dealing with performance issues (data affinity, parallelism, monitoring).
• Testing and debugging techniques.
• Managing a polyglot landscape and the explosion of platforms.
• Managing failure and graceful degradation.
