* OVHCloud is good if you deploy your production in HA fashion with higher tiers or do multi-region yourself using a vRack, real issue that they made the news with burning DCs, the fact that the customer base has been originally a gazillion cheap web servers does not help big companies going in, they are going somewhere on the SaaS
On most European cloud providers I feel like IAM is crap: workload identity is almost non-existent, API keys management is usually hellish. Same goes for encryption/isolation. I want to hear more technical feedback on most of them, devil is in the details !
1) Applications reconnecting to the new Postgres master and retrying queries
2) Persistent storage available in multiple AZs or regions for your Postgres pods (impossible on AWS for example)
From personal experience riding in the chaos that is Paris traffic for almost 10 years. I really scared myself maybe 3-4 times with bicycles running red lights at full speed.
=> Regular drivers are paying quite good attention because they need their car to go to work the next day, the real danger comes from newcomers and people who don't drive often (tourists, old people, families on weekends, etc.)
=> Anything that does not require a license (especially all these new stupid fast electric things that go over 20kmh) will make crazy tight turns without checking anything. They will get away with everything and never get stopped by the police, they don't have insurance and will not get fined for anything.
So I would add:
- Don't overspeed in traffic jams
- Don't ever come close to a bus or truck, moving or stopped (massive blind spots + not going to feel a thing running over you)
- Don't mess with car drivers (they will try to run over you and your 200kg bike)
- There will ALWAYS be a **** crazy biker with a death wish riding faster than you, whatever your speed is

From personal experience: BNP Paribas is one of the biggest bank in the world, top 5 if you exclude Chinese state owned ones, and they pay mainframe related jobs like shit.
Being young, smart and with a whole career ahead, you have no future working has a COBOL developer, no one should spend his life picking up shitty code left by his elders decades ago.
Quick facts about Paris:
- there is motorcycles and scooters everywhere
- most people make trips way superior to 5km to go to work or even to go out
- no one can really afford parking his car outside of it's own neighborhood, because you don't have discounts then => 35 to 50€ a day!
You can buy an 125cc scooter with heated grips and a nice warm rain cover for around 3000-4000€ (new) / 1500€ (old) with a 200-300km range and you don't need to pay parking anywhere (yet).
IMO French automakers are lost and this car has almost market. They know they can't compete with Tesla in the near feature on real electric cars. It's way too expensive, for sure it's not targeted at 14-18yo in Paris "intra-muros". Its only features are you don't have to wear a helmet / protects you from rain. It has almost the size of a gas Smart ForTwo without the speed and range to go on a weekend trip.
IMO any "modern" architecture can handle the load. After all Google, Apple, Facebook, Microsoft, Amazon, etc. are not running on mainframes (just taking mastodon examples).
The main difference between ARM, x86 or Power vs Z is that you can keep your CPU usage between 95-100% in production and not break everything.
Mainframes are just too expensive, even with open-source software running from the Canonical or Red Hat ecosystem. You just can't keep billing CPU consumption and sell memory sticks like it's made of diamonds. Running heavy "modern" workloads will give you a crazy stupid high R4HA MSU bills ... the clash between the relatively cheap commodity hardware philosophy of the last 10 years and the IBM way of billing high-end things is too big.
I would say mainframes are still really good at handling an ultra large bus with sky-high bandwidth but that's pretty much it. The power platform is a lot cheaper and also good at that.

1) I don't want to feed the Google behemoth
2) It's very very accurate, even tells if you should get in the back/center/front to be closer to next commute/exit
3) They joke about strikes to brighten a bit those shitty days
Lived in Paris for 20 years, everything is getting worse:
- Public transportation => many subway lines are saturated
- Traffic jams => stupid road and signals reworks (for cycling lanes mostly), it's a disaster, I am starting to think that about 90% of the population lives more than 5km from work and will never use a bicycle
- Security => cops have been in overtime for 5 years with Vigipirate & gilet jaunes and have no time for anything else
- Pollution => not a single cop around to enforce vehicles pollution laws, better hand parking tickets
Overall feels like a third world country where the state is losing control over everything.
Anyone younger and applying (scientifically) proven solutions could do.

Worst IT practices and work ethics you could imagine. Lost source code, no comments/documentation, no tests, no monitoring, no benchmarks ... most of the work was done by people without a degree in anything and stayed around for decades. It's not well thought engineering.
I enjoyed working on mainframes, I still think it's amazing technology. Some of my colleagues where the nicest people I ever met, where very skilled and taught me a lot.
But I am now a DevOps working with open source, cloud computing & containerization, everything is nicer and a lot more interesting. And I don't have to fight everyone anymore because I am the one who will have to maintain the crap of retired people (most of the time I would hit a brick wall trying to explain what is IT in the 21st century).
