    "body": "![underwater-title](/images/underwater.jpg)\r\n\r\nThe underwater data centre was a proof of concept 🤖 to test a new possible way/place for servers. Please follow my story.\r\n\r\n𝗙𝗼𝗿 𝗺𝗲, 𝘁𝗵𝗶𝘀 𝗶𝘀 𝗮𝗹𝘀𝗼 𝗮 𝗰𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝗹𝗲𝘀𝘀𝗼𝗻 𝗹𝗲𝗮𝗿𝗻𝗲𝗱:\r\n- If technology is new to me, I play around with it and then build a proof of concept.\r\n- The next phase for me is validation - I check the design and proof of concept with business stakeholders, architects and developers. It is easier to kill a demo or PoC than an entire project.\r\n- It is easier to show the demo with limited features and small integration than only a document or a diagram.\r\n- From a technical perspective, a proof of concept like this, with the physical deployment of bare metal servers underwater, is a real production deployment, like a demo.\r\n\r\n𝗬𝗼𝘂 𝗰𝗮𝗻 𝗳𝗮𝗰𝗲 𝗮 𝗳𝘂𝗻𝗱𝗮𝗺𝗲𝗻𝘁𝗮𝗹 𝗽𝗿𝗼𝗯𝗹𝗲𝗺:\r\n\r\n- How to replace a broken module: My perspective is more connected to software, so how fast can we adapt the software to new business requirements?\r\n- Face issues like potential sabotage - this is the kind of topic that is more important in the context of time, so now, in 2024, it is more critical than it was in 2018 or other time.\r\n- Single cable issue: Based on my decisions, I have similar problems with one Azure AppService instance or two or more, one SQL server or more, and SQL backup in the same or different regions.\r\n\r\n𝗔𝗻𝗱 𝗹𝗮𝘀𝘁, 𝗳𝗿𝗼𝗺 𝘁𝗵𝗲 𝗣𝗮𝗿𝗲𝘁𝗼 𝗽𝗿𝗶𝗻𝗰𝗶𝗽𝗹𝗲:\r\n\r\n- The demo has 80% of features 20% of the time: to build a complete system, we still need to finish 80% of the time to apply all required system elements (most probably logs, infrastructure as code, tests, and all missing scenarios).\r\n\r\n- From PoC delivered 20% of the time (and maybe within budget) - we can start validating our needs - and building decisions or event direction for the product.\r\n\r\nPS> Check the [article](https://www.windowscentral.com/microsoft/microsoft-waves-goodbye-to-underwater-data-centers) about underwater data centres.",
