Let’s take a look at the journey of a piece of code, from the developer’s workbench to the hand of our users. What adventures and challenges do we have to master to succeed in fast, frequent and stable releases? How does this influence our team and company culture? ——— Speaker: Daniel Gauch – Head of Development & Vice President at AXON IVY AG

2. Why?

3. @Path("/accounts")
public class AccountResource extends AbstractResource {
@Inject
GeneralLedgerService generalLedgerService;
@GET
public List<Account> getAllAccounts() {
return generalLedgerService.getAllAccounts();
}
}

4. @Path("/accounts")
public class AccountResource extends AbstractResource {
@Inject
GeneralLedgerService generalLedgerService;
@GET
public List<Account> getAllAccounts() {
return generalLedgerService.getAllAccounts();
}
@GET
@Path("{number}")
public Response getAccountByNumber(@PathParam("number") String number) {
Account acc = generalLedgerService.getAllAccounts().stream()
.filter(a -> a.getNumber().equals(number))
.findFirst()
.orElse(null);
return responseWithEntityOr404(acc);
}
}

5. What is DevOps?

6. „It works on my workstation!“
(Developer)
„The server is ok. It’s the code!“
(System Administrator)
Problem on Production!

7. „DevOps only involves
developers and system
administrators!?“

8. „DevOps is a role!?“

9. „DevOps is a team!?“

10. „DevOps is a set of tools!?“

11. „DevOps is a hype!?“

13. real business value. High-performing IT organizations have a strong and positive
impact on the overall performance of the organizations they serve. This year’s
report also tells us:
• High-performing IT organizations deploy 30x more frequently with 200x shorter
lead times; they have 60x fewer failures and recover 168x faster.
• Lean management and continuous delivery practices create the conditions for
delivering value faster, sustainably.
• High performance is achievable whether your apps are greenfield,
brownfield or legacy.
• IT managers play a critical role in any DevOps transformation.
• Diversity matters.
• Deployment pain can tell you a lot about your IT performance.
• Burnout can be prevented, and DevOps can help.

14. „There is a clear and accepted
definition of DevOps!?“

15. „DevOps is a culture, movement or practice that
emphasizes the collaboration and communication of
both software developers and other information-
technology (IT) professionals while automating the
process of software delivery and infrastructure changes.
It aims at establishing a culture and environment where
building, testing, and releasing software, can happen
rapidly, frequently, and more reliably.“

19. What about now?

22. Manifesto for Agile Software Development
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on
the right, we value the items on the left more.
