This year, we started moving off "the cloud" - 80% of our infrastructure now runs on bare-metal servers. AWS → Hetzner. Instead of: - DynamoDB - ElastiCache - ECS/Fargate - SQS - SNS - CloudWatch - X-Ray We use: - PostgreSQL - Redis - Kubernetes - RabbitMQ - BullMQ - Grafana - Prometheus We reduced our cloud bills from +$7,789.45 → $2,115.11 (on average). But most importantly: The less we depend on specific vendors, the less locked-in we become. +80% of our infrastructure can now be hosted practically anywhere. Biggest misconceptions I see: ❌ Self-hosting is extremely complex. Reality: It's less complex and "scary" than you think. ❌ AWS, Azure GCP make hosting easy. Reality: They can get very complex too. And large bills can hit hard and unexpectedly. Here's the breakdown 👇

📢 Big news: important announcement from Orange Business and Orange Cyberdefense at Vivatech today 👉 https://shorturl.at/7RU7Y 🛡 Have you heard about the #Quantum threat ? Within 5-10 years, quantum computers are expected to become exponentially more powerful than traditional computers. Experts warn about "Q-Day": the moment a quantum computer could break widely used cryptographic systems. This would expose encrypted data such as video calls, pharmaceutical patents, financial records, and more. Even though Q-Day is still years away, the threat is already here. Malicious actors are employing "Store Now, Decrypt Later" strategies, stockpiling encrypted data today to decrypt it once quantum technology matures. That’s why organizations and governments must act now to transition to quantum-resistant cryptography. At Orange, we help our clients anticipate Q-day now. With Toshiba Europe, we’ve turned #quantum-safe security into a reality: Orange Quantum Defender, which combines two cutting-edge technologies — Quantum Key Distribution and Post Quantum Cryptography — to protect our clients’ sensitive data against future threats. It includes the first operational quantum-safe network in France now live in the Greater Paris region! 🔐 It’s built for those whose data today has long lasting value - in finance, healthcare, defense, or government - and need to act now against attacks tomorrow. If it sounds like Back To The Future, well this is exactly it! Viva Technology, Taro Shimada, Christel Heydemann, Bruno Zerbib, Hugues Foulon, Usman Javaid, PhD, Wassila Zitoune-Dumontet

🌍 Why more European organizations are rethinking their cloud strategy Digital sovereignty isn’t just about where your data resides — it’s about who controls it, who can access it, and how ready you are for change. As regulatory pressure grows and geopolitical tensions rise, cloud decisions have become strategic decisions. For many, relying exclusively on non-European hyperscalers is no longer a sustainable approach. At Cegeka, we help organizations shape resilient, compliant cloud strategies grounded in: 🔹 Local infrastructure under EU jurisdiction 🔹 Hybrid and open-source architectures 🔹 Clear exit strategies for changing risk profiles Discover how we align cloud strategy with European values, regulation, and long-term control. 👉 https://lnkd.in/etudNwKn 👉 https://lnkd.in/eqfna-SU #shapingdigitaltogether #sovereigncloud #digitalsovereignty
