Passed the Microsoft Azure Fundamentals exam (AZ-900) ☁️☁️☁️

For years, AWS has been my primary cloud platform. 7 AWS certifications. Led a 234-database migration to AWS Tokyo Region. Built production features on EC2, RDS, DMS, MediaLive.

AWS was my entire cloud identity.

Then I joined Sogo & Seibu and the infrastructure runs on both AWS and Azure.

I already understand public cloud. The core concepts don't change between providers, compute is compute, storage is storage, IAM is IAM. But the terminology, the service names, the architecture patterns, the governance tools are different enough to matter when you're making real architecture decisions.

Azure Resource Manager vs CloudFormation. Microsoft Entra ID vs AWS IAM Identity Center. Azure Policy vs AWS Config. Azure Monitor vs CloudWatch. Knowing the concepts isn't the same as knowing the platform.

So instead of pretending my AWS knowledge was enough, I took the exam.

The AZ-900 covers three domains: Cloud concepts, Azure architecture and services, and Azure management and governance.

The prep helped me to learn Azure's specific terminology, pricing models, and governance framework properly and not just "close enough" translations from AWS.

Why this matters at Sogo & Seibu:

We're building enterprise systems from the ground up. Cloud architecture decisions, IAM infrastructure, vendor cost optimization, this is the work. And when you're making architecture recommendations across both AWS and Azure, you need to speak both languages fluently.

This helps me build the foundation to architect what we're building next.

Still learning. Still building.
