Design decisions that make or break cloud migrations at scale

OVHcloud’s Professional Services and Customer Success teams outline key design decisions for successful cloud migrations and scaling.

• Main announcement/action: OVHcloud highlights that early infrastructure and operational design choices (notably network architecture, landing zones, regional deployment strategy, and automation) determine long-term scalability and resilience; impacts are most pronounced within the first 6-12 months and should be validated with a maturity assessment or a targeted proof of concept.
• Background and details: The post cites a concrete example where an e‑commerce platform routed backend traffic over public IPs, causing 3× latency at a Black Friday peak; after redesigning to an isolated private network and applying Infrastructure as Code (Terraform/OpenTofu), the platform regained stability. It also stresses training, managed services, and early integration of visibility, governance, and operational runbooks to avoid costly rework.
