Definition of Cloud
● Self service on demand
● Scalability and elasticity
● Multitenancy
● Only used resources are counted

What is scaling?
![Page 8: kranonit S05E01 Sergey Burma: Welcome to cloud!](https://reader033.vdocument.in/reader033/viewer/2022051610/54869800b479590a0d8b5227/html5/thumbnails/8.jpg)
It is linear relationship betweenmoney and productivity!

Under the hoodMicro
● 1-2 EC2 Compute Units*
● 613 MiB of memory
● EBS storage only
● $0.020 per Hour
Quadruple
● 26 EC2 Compute Units*
● 68.4 Gib of memory
● 1690 GB of storage
● $3.100 per Hour
*EC2 Compute Unit ≈ 1.7 GHz Xeon
1 Quadruple for $3.100 = 155 Micro for $0.020
Sometimes it worth of it!
