The criteria that matter #

Weight, don't stack #

Not every criterion carries the same weight for your use case. Compute-heavy hosting prioritizes power; a public-facing service, connectivity and availability; sensitive data, location and certifications. The most objective approach is to weigh these criteria against your specific requirements, then score every candidate on an identical matrix.

FAQ #

Is the highest Tier always the right choice?

No. A higher redundancy level costs more and is only justified when your availability demands it. Over-specifying is waste.
