The underwater data centre was a proof of concept ๐Ÿค– to test a new possible way/place for servers. Please follow my story.

  • If technology is new to me, I play around with it and then build a proof of concept.
  • 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.
  • It is easier to show the demo with limited features and small integration than only a document or a diagram.
  • 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.

  • 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?
  • 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.
  • 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.

  • 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).

  • 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.
