3. 3. From cloud mechanics to financial markets

   Four cloud layers

   Why platforms attract

   Cloud in financial markets

   Edge and blockchain

4. 4. 01. Cloud technologies

   A resource pool, four layers, and three service models

5. 5. The cloud is a dynamic resource pool

   A consumption model, not hardware ownership

   Resources available on demand

   Configuration changes dynamically

   Pay-per-use charging

   Provider commits to an SLA

6. 6. Each layer screens off the complexity below

   Hardware → Infrastructure → Platform → Application

7. 7. The service model sets the responsibility boundary

8. 8. 02. Why cloud is attractive

   Business needs the top; the platform owns the base

9. 9. Business only needs the top layer

10. 10. Kubernetes screens off lower layers

    Declarative deployment description

    Large community and ecosystem

    Fully managed in public clouds

    Open source lowers vendor lock-in

11. 11. Platform frees product at a cost

    Product team

    Focus on business features

    Fewer infrastructure details

    Platform team

    Reliable foundation

    Platform development and support

12. 12. 03. Cloud in financial markets

    BaaS, nine services, and four market roles

13. 13. BaaS sells a ready business process

14. 14. The regulator counted nine cloud services

    From infrastructure to a cloud marketplace

    Infrastructure, security, data exchange

    Accounting and payment access

    Blockchain applications and RegTech

    Financial supermarket and marketplace

15. 15. Roles differ by their core competence

16. 16. Rules are catching up with technology

    Adoption was low in 2018

    Risk-management rules were missing

    Restrictions later became softer

    Hybrid choice remains contextual

17. 17. Five constraints shape the capacity mix

    CapEx versus OpEx

    Resources in the required region

    Non-functional requirements

    Regulation and migration cost

18. 18. 04. Additional context

    Edge computing and distributed ledgers

19. 19. Compute stretches from devices to the cloud

20. 20. Blockchain registers and validates transactions

    Some nodes initiate transactions

    Other nodes validate them

    Logically there is one chain

    Immutability simplifies replication

21. 21. The difference is the trusted third party

22. 22. 05. Further reading

    Sources explicitly named in the talk

23. 23. Four anchors for continuing

    van Steen, Tanenbaum — Distributed Systems

    Bank of Russia — cloud in finance

    Maslow's hierarchy of needs

    Blockchain Basics — book review

24. 24. Cloud moves responsibility upwards

    Layers separate apps from hardware

    Platforms free product teams

    BaaS abstracts a business process

    Finance constrains choices through risk

    Edge and ledgers widen distribution
