CodeFreeze 2018 - There is no such thing as a microservice!
In early January, I gave a keynote at Code Freeze 2018 in Minneapolis. This fantastic conference lived up to its name - with windchill it was -9F outside. Here I am with the other keynote speakers: @randyshoup and @micheletitolo
About the keynote
The title of the talk was “There is no such thing as a microservice!”. The key points are:
- The microservice architecture is an architectural style that structures an application as a collection of loosely coupled services.
- The goal is to support the continuous delivery/deployment of software by small, autonomous teams. Each team is responsible for one or more services. Service size is much less important.
- It makes little or no sense to discuss individual microservices or, for example, to “use a microservice to solve a problem”.
- The microservices pattern language enables you to solve key problems when using the microservice architecture
- An event-driven architecture is a good way to tackle distributed data management challenges that arise microservice architecture.
