Modularized Source code - Built Separately

Smushed Together -> 1 Deployment Entity

----------------------------------------------------------

Web Apps became complex

So deploying them as 1 Deployment unit was a challenge

Complexity increased Deployment Size 

1 New Guy makes his 1st Commit -> and do we need to deploy whole thing all over again

Monolithic Architecture - "Smushed"

Sales -> Festivals -> Spike Traffic 

Scalability for deployment 

A small portion/module of App needs to be scaled - Not Whole App 

What can be done better here ?

Test only 1 Sub App - 1 Microservice

Scale only that 1 Microservice

Talk to each other -> using Rest

Smaller Mini Applications instead of 1 Big Monolith

Advantages

2) Technology 
3) Scalable 

1) Deployment Flexibilty 

CONS/Disadvantages

1) Architecture - How to Split Services/Where???
2) Service Discovery -> Which Services to call ?
