- 15. Big IT Slow IT (not slow as in slow food….)
- 16. “The goal is to have more control over the system than it has over you.” DevOps
- 17. IT Legacy is #1 obstacle for innovation Major corporations depend on core systems that - Are 15-20 years old - 3-4 persons know - Some staff is retired, some will be it within 4-5 years - Technology support is slow - Are somewhat documented - Have few formal test cases, but the staff know how to test Application Landscape Report 2014
- 18. IT Legacy is #1 obstacle for innovation Major corporations depend on core systems that - Are 25-45 years old - 1-2 persons know - All staff are retired, or will be it within 2-3 years - Technology support is gone - Are undocumented - Have no/few formal test cases Application Landscape Report 2014
- 19. The ability to innovate is strictly coupled with the ability to fail fast
- 20. Nine observations on IT Complexity 1. Most IT systems are too complex. 2. "Best Practices" increase complexity. 3. Complex systems cost more to build. 4. Complex systems are harder to deliver. 5. Complex systems are less secure. 6. Complex systems are less reliable. 7. Complex systems are less agile. 8. Complex systems cost more to run. And 9. Existing management approaches ignore complexity.
- 21. But what is Simple-IT, then? 1. Non complex 2. Small building blocks 3. Autonomous 4. They “know nothing” 5. Service based 6. Dynamic 7. Like lego bricks 8. Pace layered - exposes an OpenAPI 9. Joint development and operations Knowing nothing? Image: Daily Mail A.k.a. Agile Architecture
- 22. DevOps is about increasing your responsiveness to customers
- 23. Devs New features, fast! Ops Uptime, uptime & uptime
- 24. Devs Uptime Ops New features, fast! But what-if…
- 25. …should it be one joint team per system/service? Or….
- 26. Autonomous system? Totally separate parts Separate lifecycles! Loose coupling paw rihk-titt

- Ops – will have to receive ”any crap” since Dev just want to rush it Devs – will have to wait until Ops feels they are ready
- Whatif Devs were meassured on uptime & Ops on new features? Just a thought….
- ”But we already outsourced ops and kept dev...”

- The train is a stable, robust mode of mass transportation. It is not flexible but reaches its goal in a predictable, straightforward way (ignore possible regional differences, we are not comparing Great Britain and Scandinavia here). It is based on an infrastructure that is designed and built to last for decades
- The BUS is also a relatively stable mode of mass transportation, but clearly with more flexibility. A bus can take a detour if circumstances require, and it can be used for alternative purposes on top of the fixed schedule. Moreover, it usually connects directly with the train system.
- Andreas Gyllenhammar: “75 kg person in a 1500 kg car is a lot of dead weight and plain stupid” The CAR is a much more agile, individualized means of transport. It can take a person – or a small group of people – to most of the places they want to go. There are many different types of cars to choose from and their owners will configure and adapt them to reflect their individual, differentiated styles and personalities. People – particularly men, admittedly – often confess to “love” their cars: Their car gives them a sense of freedom and it is often tightly integrated with their everyday lives.
- The BIKE is a lightweight, extremely flexible and individual method of transport. It can be used for the “last mile,” bringing you to places even cars cannot reach. In crowded areas, scooters are faster than any other means of transport. There are many different types of scooters and they can only transport one or two people at the same time. It is easy to rent a scooter – just for a day or so – and explore parts of the city in a flexible, cost-effective way. And it is fun too. Depending on the regional situation, a bicycle would be a suitable metaphor as well, as it is fast, cheap, does not need a heavy engine or lots of fuel, and is extremely agile.
- All of these modes of transport are tied together through a HUB, best seen as a modern train station with carefully provided additional services. Such a hub is truly multi-modal in that trains, buses, cars and scooters all can conveniently “dock” and people can easily change their means of transport, while benefiting from a host of add-on services. A well-designed station like this functions as the pumping heart of the city
