Comparison
Quick answer
Cloud architects specialize in designing infrastructure on cloud platforms (AWS, Azure, GCP) — network topology, security, cost optimization, and cloud-native service selection. Solutions architects design broader technical solutions that may span cloud, on-premise, and third-party systems — translating business requirements into end-to-end technical architectures. The distinction lies in whether the scope is cloud-specific or technology-agnostic.
For purely cloud-native companies, a cloud architect's deep platform expertise is more valuable than a broader solutions architect. For enterprises with hybrid or complex multi-vendor environments, a solutions architect's ability to design across the full technology landscape is essential. In practice, senior engineers often hold both capabilities — the distinction matters most when evaluating specialist consultants or deciding which type of architect to hire.
