  • Why do we test applications

    Hi there, If we want to discuss testing applications designed and created by AI wehave to understand why do we test applications created by developers? Don’t we trust developers? Don’t developers trust themselves? No. We do test our applicatios for several other reasons. Not because oftrust. I will discuss them soon. So even if we… Read More »Why do we test applications

  • How to test AI created systems

    Hi there, With the conversational programming and systems build entirely by AI wehave to think how to test those systems. Testing is a crucial part for developers to know if the system is doing theright thing. How we enforce AI to double check created systems? Should we trust AI? Ifso we don’t need testing. Maybe… Read More »How to test AI created systems

  • Will conversational programming with AI produce microbes

    Hi there, I am getting closer and closer to finding what a microbe is. Recentlythanks to the Simon Wardley YouTube video about Wardley Maps I realisedthat the driver behind our Infrastructure from pets and cattle tomicrobes journey was: ease of building higher order systems. This is the reason why we moved infrastructure from servers and… Read More »Will conversational programming with AI produce microbes

  • About conversational programming and AI

    Hi there, Can AI make developers obsolete? It can already write code so we actuallydon’t need developers. Right? Not exactly. Because programming is not only about code, but also about thedesign. And right now AI cannot discuss problems with business people andguide them and discover the solution. But this will change. Imagine having a proper… Read More »About conversational programming and AI

  • Is this a monolith yet

    Hi there, Currently a lot of developers and architects cheer for the monolith and areagainst serverless (or microservices). Plus, now they use the Amazon PrimeVideo case to prove their point. That even the Amazon people cannot make aserverless app profitable and switched to a monolith. The problem is that they didn’t switch to a monolith.… Read More »Is this a monolith yet

  • Decision to change the infrastructure should be an easy one driven by current architectural drivers

    Hi there, In the Amazon Prime Video article by Maricn Kolny, he said one thing thatwas quite interesting: “We experimented and took a bold decision: wedecided to rearchitect our infrastructure”. What is interesting here is that they have to be bold to make thatdecision. I don’t have the full picture, but it has a feeling… Read More »Decision to change the infrastructure should be an easy one driven by current architectural drivers

  • Speedboats and cruise ships in the Amazon cloud

    Hi there, There is [[no such thing as the final architecture]]. One thing that strikes me about this ongoing Amazon Prime Video discussionis that they made the mistake of using serverless to build their system,because they have now switched to a monolith (is it really a monolith?). There are few wrong assumptions here. Let me… Read More »Speedboats and cruise ships in the Amazon cloud

  • AI + Cryptocurrencies vs KYC

    Hi there. I wrote this email myself, personally In the near future we will see a lot of such statements because of all thatAI (Artificial Intelligence) generated content.

  • The most important thing about observability

    Observability is a non-functional requirement (NFR) of an IT system.The main goals are: to know if the system works on production to know if the system works properly to know if and when the system will break The idea behind observability is that, if I know that my system will breaktomorrow, I can fix it… Read More »The most important thing about observability

  • Good enough performance

    Performance is one of the non-functional requirements (NFR) for IT systems.We tend to think that performance has to be very high. In general, yes. But not always. As it is a very important driver, thebottom line is that performance has to be good enough. In Poland we have the banking system Elixir that runs sessions… Read More »Good enough performance

  • About wrong solution designs

    Yesterday I’ve mentioned that architect should design wrong solutions. This obviously has a broader context. The idea behind this statement isthat architecture should be understood by everybody. We should discuss and reason about WHY a design looks like that. Forexample why there is an async flow for a scenario. Or why a given serviceis upstream… Read More »About wrong solution designs

  • The microservice architecture is for developers

    Sometimes I hear the argument that we need to do microservices for customerexperience. As the more traditional monolith approach (a modular monolith)is seen as slow and clumsy. But this is not the case. The main reason we have microservices is forindependentdeployments. The monolith vs microservice change should have zero impact on yourcustomers. It is not… Read More »The microservice architecture is for developers
