This talk is basically a successor of the "DevOps is not enough talk", but with a broader focus. In the talk, after a short motivation, I try to take stock of the current state of IT from different points of view. After looking at, where we came from and where we are, I add the most important trends I currently see that affect us in IT. But knowing where we came from, where we are and where we are going to usually is not enough. The key point is using this information - in this talk for evaluating your current position as a software engineer and figuring out your desired future position. As all the details from the first part of the talk make it hard to do this evaluation, I suggest creating a model (actually a framework) on a reduced detail level that makes the evaluation and planning easier. Defining that framework is the third part of the talk. Finally, the last part consists of some general recommendations that - based on my understanding - help you as a software engineer to stay ahead of the curve for a while. While this is extremely much stuff (I really consider to split that plethora of information covered in this talk up in several, single-topic talks) and as always the voice track is missing, I still hope that the slide deck gives you a few ideas worth pondering.

3. Have you ever felt like (almost) everyone
and everything in IT is going mad?

4. Like everything is getting more and more
complex every week?

5. And you already feel like you hardly can
hold together all the bits and pieces?

6. But you are getting less and less time
to pick up the plethora of new stuff?

7. And all that “Agile” just feels like a big hoax
which makes things worse than better?

8. Do you sometimes feel like you might
miss what is really important?

9. And instead waste your time
in a crazy rat race to nowhere?

10. Will AI replace your job in a few years?

11. And what about IoT, Blockchain
and all those other “disruptions”?

12. Do you sometimes ask yourself
if you are still on the right track?

13. Or that you might focus
on the wrong things?

14. But what are the “right” things?

15. Do you sometimes feel like this?

16. Or like this?

17. Then it might be time for a little
hitchhiker’s guide to the IT of today

18. But first of all ...

51. More complementing viewpoints
• Evolution of “Make or buy”
• Double Helix
• Local computing vs. distributed computing

52. Understanding current IT trends
Complementing the picture

53. Meta-Trend #1
Digitization (whatever that means ...)

54. Digitization (Definition)
• Blurry and misleading term – yet an important change driver
• Response to market demands and technology evolution
• Core: IT becomes integral part of business offerings
• Consequence: Cross-domain boundaries start to dissolve
and leverage – currently still unknown – business models

55. Digitization (Effect)
• Uncertainty regarding business model viability
• Effect: Short iterations, pervasive metrics (incl. measuring
outcome), A/B testing, smart rollout strategies, ...
• Dissolving domain boundaries
• Effect: API, platforms, ...
• Adaption of persistent requirements to a new context
• Effect: Poor connectivity as a constraint, re-thinking
accessibility, “developer experience” on the API level, ...

56. Meta-Trend #2
Customer expectations

57. Customer expectations
• Great user experience (UX)
• Fast response times
• Multi-device capabilities
• Zero downtime
• Strong Security (regarding data privacy)
• Adapts to customer’s needs and demands

58. Resulting IT trends

59. Moving fast
• Minimize cycle times to accelerate the feedback loop
• Response to business model uncertainty
• Goal is to minimize idle and value-reducing performances
• Massive paradigm shift (“Re-thinking IT”)
That is what DevOps actually is about!

60. Focus on frontends
• The battle for customers gets decided in the frontend
• Backends just need to work and must not get in the way
• UX and UI design become key differentiators
• Backend becomes commodity
• Bear all types of frontends in mind (incl. IoT, API, ...)

61. Cloud-native and serverless
• Reduce vertical integration depth
• Focus on value-creating IT performance to move faster
• Newest incarnation of “make or buy”
• Managed services as successor of standard software
• FaaS to orchestrate managed services
• Managed container and batch jobs for deep business logic

62. Ambient computing
• Shift towards human-centered user interfaces
• Complemented by context-aware computing & UIs
• “Mobile first” is just a transitional step
• New types of human-machine interaction
• Voice, gestures, tactile, ...
• Augmented by AR & VR interface capabilities

63. InfoSec
• Indispensable supplement for most needed technologies
• Cloud
• Wireless
• IoT
• Mobile
• ...
• Must be an integral part of all stages of the IT value chain

64. IT enabled trends

65. IT enabled trends
Artificial intelligence / deep learning
Internet of Things (including industry 4.0)
Maker movement (including 3D printing)
Blockchain
• Currently hyped topics with disruptive potential
• Actual future impact not yet clearly foreseeable

66. Evaluating your position
Finding out where you are and where you want to go

67. Step #1
Create a framework

76. ... will lead you to this model

77. You may pick

Deliver large batches at minimized
costs towards slow markets
Post-industrial IT
Quickly adapt to ever-changing needs

shares many of the other properties

• As architect, you will need to get a grasp of all directions

98. Step #4
Define your personal evolution plan

99. Define your personal evolution plan
• Defining the plan is the easy part
• Read the literature, do the trainings, train your skills, ...
• Still, it will require time and discipline
• It’s a combination of personal and company game
• You cannot expect your company to cover all the efforts
• You will usually need to invest some of your private time
• And if your environment does not support you
• “Love it, change it, or leave it”
• Trade-offs are fine, but in the end they are your decision!

100. Staying ahead of the curve
Some general recommendations augmenting your path ahead

101. Understand post-industrial markets
• Speed trumps perfection – Rethink everything!
• Really, really understand the implications of uncertainty!
• Understand the difference between output and outcome
• Understand the ideas of bets and options
• Dismiss cargo-cult agility – learn what “Agile” really means
• It is a revolution in your head!
• But it should be an evolution regarding implementation
• Otherwise you will certainly overstrain your organization

102. Cross-functional teams
(organized by business capabilities)
Autonomy
(incl. E2E responsibility)
Decentralized control
Microservices
Continuous Delivery
Heterogeneity
Cloud and Containers
Resilience
Operations automation
Craftsmanship & mastery
Outcome-driven
Beyond budgeting
Feature flow
Lean EAM
Continuous improvement
T-Shaped people
(being empathic)
DevOps
Quick feedback loops
Curiosity

103. Master the timeless wisdom
• Especially master the foundations of good design
• “Loose coupling, high cohesion” & “separation of concerns”
• “Information hiding” especially with respect to API
• Domain-driven design can be a useful starting point
• Good design skills are more relevant than ever
• Affect understandability, changeability and extensibility
• Affect usability, stability and acceptance at API level
• Affect robustness, availability and scalability at runtime

104. “I would advise students to pay more attention to the
fundamental ideas rather than the latest technology.
The technology will be out-of-date before they graduate.
Fundamental ideas never get out of date.”
-- David L. Parnas (http://www.sigsoft.org/SEN/parnas.html)

105. Become T-shaped
• Generalists trump specialists
• Pure subject matter experts are an industrial concept
• Collaboration requires understanding your collaborators
• Leave your comfort zone once in a while
• Still, have your area of expertise
• Deep knowledge is still needed – but in a inclusive way
