Introduction to the cloud architect profession
The cloud architect is a technical expert responsible for designing, deploying and optimising IT infrastructure in the cloud. They design scalable, secure and high-performance architectures on platforms like AWS, Azure or Google Cloud Platform.
Their role goes beyond simple technical configuration: they must understand business challenges, optimise costs (FinOps), ensure security and compliance (GDPR, ISO 27001), and support development teams in adopting best practices. They master Infrastructure as Code (IaC), containerisation, orchestration and automation.
