8. … CS1 … CSN Customer1 CustomerN Initial setup
Customers could have different client count, and therefor different load.

9. Cloud Services 100 servers 25 customers 4 new servers per customer
1 core
3,75GB RAM
25 customers
4 new servers per customer
Monolith
Multiple applications/services
This won’t scale

10. 2 birds with one stone New infrastructure needed
New application deployment needed
Evolution over revolution
Solution:
Event Driven Service Oriented Architecture
