## Description

The basic premise is that by making our service landscape more modular we increase innovation speed at the company level. 

Different factors while taking that decision. 
Coupling, Cohesion, Encapsulation. 
Lets make trade-offs between them when making design decisions.

Lets take a real problem and design a system and measure its modularity.
Pure maths can help us making faster decisions, hence increase innovation.

Unfortunate: 
We use the term microservices
nano services / functions | lambdas
it’s not about the size of the boat, but about the motion in the ocean.
Smaller is not (perse) better
Reflect on cost vs benefit

So how can we design better?
What is modulith?
Perfect marriage of a monolith and boundaries of a microservice  is clearly a golden bullet.

Results:
system ~ bounded context
system != deployable
system >= 1 deployable
strong cohesive deployables 
loosly coupled deployables
belong together
exposed under a single api
isolation by system
