How to Choose
Start from your workload, not the provider. If you need dense GPU capacity and data residency with support that helps you plan power and cooling, a provider like Techno Digital that spans colocation, IaaS, and GPU fits well. If you need the largest owned metro footprint or a global estate, the bigger operators serve that. Ask each for the specific facility, its tier, density capability, and connectivity at your chosen site.
