Before committing to Nanoservices

Nanoservices live within the sizing constraints of Microservices. Smaller size of modules enables the service to maintain and change. Therefore, a system composed of Nanoservices can be easily extended.

In a typical domain driven system, each class and function can be modelled as a separate Nanoservice. This leads to an increase in infrastructure costs such as that of application servers and monitoring solutions. Since implementing a complete business solution using Nanoservices might involve deploying several hundreds to a couple of thousands of Nanoservices, the infrastructure costs on the desired cloud platform need to be as low as possible. In addition, Nanoservices should not be long running or resource intensive.

Nanoservices require a lot of communication among themselves. This may lead to degraded performance. On certain platforms, Nanoservices may share a process, which may cause resource starvation and take away technological freedom. This approach...
