4. About costs...

5. Directly from Genova

6. My rst CQRS infrastructure in early 2010(late2009)

7. Mainly because of di erent Command/Query
speeds

8. Cost reduction thanks to autoscaling groups

9. Fixed hardware (virtual machine) provisioning

10. E ective resources consumption

11. Resources consumption VS xed provisioning

12. Thanks to Autoscaling Group

13. Without autoscaling group
With autoscaling group
We save 732 $ per month so 8784 $ per year!
60 t2.small instances 100% = 1098$ per month
10 t2.small instances 100% = 183$ per month
50 t2.small instances 6 hours per day = 183$ per month

14. Autoscaling groups with t2.small grows by steps
of 0.03$ per hour

15. Autoscaling groups with t2.micro grows by steps
of 0.02$ per hour

16. What if i can pay per single request?
0 requests means 0 $
1 requests means 0,000000208$
1M requests means 0,208$
60M of requests per month = 12,48 $

17. So i can pay only for my real needs!

18. With serverless we have bills based on the actual
amount of resources consumed by an application

19. On AWS we can join API Gateway + Lambda to
work with a Serverless infrastructure

20. Thanks for listening
