1. Event-Driven Architecture (EDA)

Problèmes résolu:

• timeout si un service est lent
• 1 service down = toute la chaîne bloquée
• temps de réponse imprévisible

Pièges à éviter:

1. Event explosion
2. Debugging de l'enfer
3. Eventual Consistency mal gérée
4. Cohérence transactionnelle

2. API-First & API Gateway pattern

API-First : Concevoir l'API avant d'implémenter le service
API Gateway : Point d'entrée unique qui orchestre, sécurisé, et monitore les APIs (et Backend for Frontend)

Pièges à éviter:

• moins de 5 api et un seul frontend
• communication interne uniquement
• latence critique

3. CQRS + Event Sourcing

Command Query Responsibility Segregation: séparer les modèles de lectures et d'écritures; deux bases de données différentes optimisées pour leur usage.
Event Sourcing : Au lieu de stocker l'état actuel, on stocke tous les événements L'état actuel est reconstruit en rejouant les événements.

Cas d'usage: Performance, audit et compliance, analytics temps réel

Pièges à éviter: complexitée surévaluée, eventual consistency, gestion de la mimgration de schéma

4. Saga Pattern

1.There are three states of being. Not knowing, action and completion.00

2. Accept that everything is a draft. It helps to get it done.
3. There is no editing stage.
4. Pretending you know what you’re doing is almost the same as knowing what you are doing, so just 5. Accept that you know what you’re doing even if you don’t and do it.
5. Banish procrastination. If you wait more than a week to get an idea done, abandon it.
6. The point of being done is not to finish but to get other things done.
7. Once you’re done you can throw it away.
8. Laugh at perfection. It’s boring and keeps you from being done.
9. People without dirty hands are wrong. Doing something makes you right.
10. Failure counts as done. So do mistakes.
11. Destruction is a variant of done.
12. If you have an idea and publish it on the internet, that counts as a ghost of done.
13. Done is the engine of more.

There is also an illustration for it

Here's the thing: 99% of companies don't need them. The top 1% have tens of millions of users and a large engineering team to match.

The fun thing about Postgres is there is already an extension for that: PostGIS, Full-text search, JSONB, TimescaleDB, pgvectorm, and many for AI

Each database add hidden costs: backup strategy, monitoring dashboards, seceurity patches, on-call runbooks, failover testing.

SLA math: Three systems at 99.9% uptime each = 99.7% combined

1. unsystematic
2. valid
3. semantic
4. Accessible
5. Required-only
6. hyper-optimized

So in order to set up one, the data center needs power, cooling, servers and software. The post goes in-depth about it. The list of softwares available is a great inspiration.

All of our storage arrays use mkv. The main array is 3PB of non-redundant storage hosting our driving data we train on. We can read from this array at ~1TB/s, which means we can train directly on the raw data without caching. Redundancy is not needed since no specific data is critical.

Enfin! L'attribution de marché se fera fin mars 2026

Parmi les opérateurs déjà qualifiés SecNumCloud et donc théoriquement en position de postuler pour prendre le relais de Microsoft figurent des acteurs français comme OVH, Cloud Temple ou Sens, un opérateur constitué par le groupe français Thales mais qui utilise la technologie «cloud» de Google.

Rules can be ignored, but safety rules should always be considered. They are always defined after accidents.

So despite being a German citizen, my data protection rights depend entirely on the enforcement capacity and willingness of a foreign regulatory body. [...] This is the reality for any cross-border GDPR complaint. The regulation is EU-wide, but enforcement is national.

Some claimed it was spam and "an email automatically processed by upstream IT security systems and does not reach the responsible organizational units is legally not considered as received.

The burden is entirely on you to prove they received it.

Changes are needed

1. Cross-border enforcement needs to actually work.
2. The spam filter loophole needs to die.
3. There need to be mandatory minimum fines.
4. Data protection offices need funding and accountability.
