Traits

A monolithic application has a number of traits:

• Contains the whole or a big amount of business logic
• Accesses persistency services
  • Databases
  • Caches
  • Assets

In general terms, a monolith could be internally structured in a number of modules, which encapsulates code and data that implement a particular functionality.

For the purpose of further analysis, let's assume that a monolith has all the business logic and data access logic combined in one. This doesn't mean that the monolithic application includes the persistency services, but that it merely consumes them.
