It is the time of the year again, almost time for Saint Nicolas and Christmas but still a few weeks to go. But this at the same time, re:Invent conference time. One of the sessions where I am looking forward, is the keynote of Werner Vogels, CTO of AWS.

Not because of the big launches, but to know his take on the current technology evolutions. This year ain’t different.

It already starts with a classic viool orkest (TODO ) which is really nice. I expected some Guitars, but those were already present at the keynote from the

The key take away here is to add cost as a non-functional requirement. Make sure that you can tweak the cost of the application you are building. Well, not you but the business users of the application! They know what is import and what is not.

Key take aways

• Cost
• Measure cost
  How more you are aware of the costs in your system and where they originate, the more you can improve it. Bear in mind that cost is a close proxy to sustainabillity. So lowering the cost of your architecture, is not only god for you but also for the environment.

At that moment we were already almost 1 hour without mentioning AI. Yes, the second part was about AI and Machine Learning. But I really liked his approach on AI. He mearely declared that AI is able to find the needle in the haystack, which gives us a lot of possibilities. These possibiliiteis where avaialble previously but, they took much longer. Still everything fails all the time, also at the AI models, where false positives or false negatives can happen. But sometimes it is just better to have some false positives in stead of missing a true positive.

• AI has its purpose and is here to stay
• AI is
• Machine Learning is still relevant today even i you have Deep Learning, Neural networks etc

Oh yes, there were some launches as well in this keynote

The frugal Architect

• Book from Werner volges which is about the last 20years experiencs

Design

• Cost is a Non functional requirement

• ecoonmy of scale

  • Business decision are aligned with technology decisions

  • Lambda was running in isolation on T2
• Architect with cost in mind

not cost efficient due to lift and shift - recusing streaming cost with 80pct
