Pierre BAILLET - 27th, April 2017

2. Intro

3. About… this Talk
- What drives companies?
- Why keep on top of technology?
- The server’s journey across the ages

4. About… me
- Pierre BAILLET, @octplane
- DevOps consultant, Technical Manager @ IPPON Technologies

5. Behind this talk
- social evolution:
- Computer science is now taught in school
- New ways of training: better schools, mooc
- Developers, administrators, ops, devops: new jobs
- technical evolution:
- Languages
- Frameworks
- business evolution:

6. Companies
&
Technologies

7. What drives companies?
- Business!
- Business!
- Business!
- Business!

8. What drives companies?
- Business first: the only value we should worry about
- Business Continuity: the metric that will keep our business alive
- Business TTM: the duration that will ensure our business lasts
- Business TCO: the cost that will make our business profitable

9. Why keep on top of technology?
- Spend less money: Leverage for Cost optimization
- Earn more money: Kill the competition
- Earn more money: create new uses: Disrupts the industry (uberization)
- Earn more money: create new markets: New perspectives
- Avoid bankruptcy: transform to adapt: Digital transformation

10. The Server’s
Journey

11. 1642 > The Golden era
- Blaise Pascal
- Charles Babbage, Ada Lovelace
- Computers are mechanical machines
- They “compute”

12. 1970 >The transistor and lamp(!) ERA
- First Computers
- Huge machines, room sized: heavy industry: knobs and
paper with holes
- Internet appears, first as a research project (ARPANET,
CYCLADES): wires and electrical impulsions

13. 1980 > banks and universities
- Computers sneak in banks (COBOL anyone?)
- Actual computer scientists!
- Industry workers still use old industrial computers
- At the same time, rise of the first personal computers: Alice, Atari ST,
Amiga, …
- Youngsters experiment Asm, Basics and 16/32 bit coding

14. 1991 > From the desktop to the datacenter
New contenders:
- GNU/Linux by Linus Torvald
- Visual Basic by Microsoft, and later php
Era of home grown development:
- First web applications (CGI, PHP, ASP)
- First desktop rich applications (TCL/TK, VBA, VB, C++)
First datacenters, servers and racks.DEV OPS METAL INFRA

15. 2006 > I.A.A.S.
- Infrastructure As A service, also known as the Cloud
- First public instance of a Cloud (AWS)
- Underlying structure for code applications : INFRA + METAL
- Servers, disks, virtual networks, …
- Pay in Advance, Pay on demand

16. 2008 > P.A.A.S.
- Platform As A Service
- Lead by Google and its AppEngine
- Little by little, persistent services move behind the API interface : relational databases,
nosql, ...
- Rise of smarter services : notifications, messaging, queues, …
- More and more vendor lock-in
- Leverage the Cloud technology to let developers focus on their core job: application code.DEV OPS METAL INFRA

17. 2014 > F.A.A.S.
- Function As A Service: The Serverless!
- A simple interface
- Scaling is infinite (!)
- Greener approach (?)
- Need an API Gateway
- We only pay for the CPU slices we actually useDEV OPS METAL INFRA

18. 2020 > X.A.A.S.?
- Everything As A Service
- Less coding competencies, more business/product skills
- The pizza team now includes business specialists
- IA is on the rise: replace some of the simplest development
- Vendor Lock-in at its maximum
- Open the path for new standards

19. Outro

20. Serverless - Where do we go from here?
- Cost reduction is the lead adoption factor
- Focus on the core business value
- There are still ops, but behind an API interface
- Vendor lock-in stronger than ever
- Community (dev’ framework) and norm (packaging) are
slowly emerging

21. Any question?
