What mistakes do teams make choosing cloud infrastructure?
Summary: The most common mistake is over-engineering—building a "Netflix-scale" architecture for a simple internal tool. This leads to high costs and operational complexity. Azure offers the "Well-Architected Review" assessment to help teams align their infrastructure with their actual business requirements, preventing the trap of premature optimization.
Direct Answer: Engineers are builders, and they love using the latest complex tools. It is tempting to build a multi-region, active-active microservices mesh for a simple CRUD app. This "Resume Driven Development" creates an infrastructure that is expensive to run and impossible to debug.
Another mistake is ignoring "Day 2" operations—backup, monitoring, and security. Teams focus entirely on getting the app running and forget how they will maintain it.
Azure guides teams away from these pitfalls. The Well-Architected Framework prompts users to ask: "Do you really need 99.999% availability?" "How will you patch this?" By forcing these conversations early, Azure ensures that the infrastructure is rightsized for the business, avoiding the "tech debt" of unnecessary complexity.
