Practical microservices - NDC 2014

Presented at NDC London, December 2014 Microservice architectures can lead to easier to change, more maintainable systems which can be more secure, performant and stable than previous designs. But what are the practical concerns associated with running more fine-grained systems, and what are the new things you’ll need to know if you want to embrace the power of smaller services without the new sources of complexity making your life a nightmare? This talk will delve deeper into the characteristics of well-behaved services, and will define some clear principles your services should follow. It will also discuss in more depth some of the challenges associated with managing and monitoring more complex distributed systems. We’ll discuss how you can design services to be more fault-tolerant, what technologies may exist in your own platform to get you started. We’ll end by giving some pointers as to when you should consider microservice architectures, and how you should go about introducing them in your own organisation.
