Short answer

• For enterprise workloads in Amsterdam you can host in: major carrier-neutral colocation campuses (Interxion/Digital Realty, Equinix), large colos/operators (Iron Mountain, EvoSwitch, NorthC, NLDC), or on‑ramps to hyperscalers (Microsoft/Google/AWS via local sites or direct-connect/expressroute). These facilities give dense connectivity (AMS‑IX, NL‑IX), enterprise SLAs, certifications and hybrid-cloud interconnects so they’re the usual first choices. (datacentermap.com)

Where to look (operators with Amsterdam presence)

• Digital Realty / Interxion — large carrier‑neutral Amsterdam campus (Science Park, Schiphol campus) with huge peering ecosystem and metro interconnects. Good for cross‑connects, cloud on‑ramps and build‑to‑suit. (datacentermap.com)
• Equinix (AM1–AM7, etc.) — major interconnection hubs in Amsterdam with many carrier and cloud exchanges. Good for multi‑cloud, direct connect and financial/low‑latency use cases. (i4networks.nl)
• Iron Mountain — hyperscale-ready campus near Amsterdam, wide compliance portfolio (ISO, SOC, PCI) and large power footprint. Suited to regulated enterprises. (ironmountain.com)
• EvoSwitch — green, modular colocation in the Amsterdam region with multiple carrier options. Good if sustainability and modular scale matter. (EvoSwitch.com)
• NorthC / NLDC and other regional colos — multiple Amsterdam‑area sites (Kabelweg, Aalsmeer, Schiphol) offering local density and AMS‑IX connectivity. (northcdatacenters.com)

Key technical and business considerations (what to evaluate)

• Connectivity and peering: presence at AMS‑IX / NL‑IX and number of carriers, cross‑connect options and latency to your customers or cloud region. Amsterdam is one of Europe’s biggest IX hubs — use sites with PoPs to reduce transit and latency. (peeringdb.com)
• Cloud on‑ramp & hybrid: if you need Azure ExpressRoute, AWS Direct Connect or GCP Interconnect, pick a facility certified/connected to those on‑ramps (many Interxion/Equinix sites provide them). (datacentermap.com)
• Compliance & certifications: confirm ISO 27001, SOC 2, PCI‑DSS, GDPR support and any sector rules you need (healthcare, finance, public). Iron‑Mountain and large colos list these explicitly. (ironmountain.com)
• Resilience & power density: check redundancy levels (N+1, 2N), available kW per rack, PUE and expansion capacity for high‑density / GPU/AI racks. Large campus operators advertise scalable MW and expansion plans. (ironmountain.com)
• Physical access / Smart Hands: proximity to your ops teams or reliable remote hands services for 24/7 maintenance. (ironmountain.com)
• Sustainability & energy sourcing: many Amsterdam facilities now offer renewable‑matched power or low PUE (important for ESG reporting). (ironmountain.com)
• Pricing & contracts: compare colo space vs. dedicated cages vs. bare‑metal/cloud, interconnect fees, cross‑connect costs, and minimum contract terms.

Typical deployment choices for enterprises

• Hybrid core: colocate firewalls, routers and stateful appliances in Equinix/Digital Realty and connect to Azure/AWS/GCP via dedicated links for predictable performance. (datacentermap.com)
• Fully colocated: all servers and storage in a carrier‑neutral campus (good for data sovereignty and regulated workloads). (datacentermap.com)
• Edge + cloud: put latency‑sensitive services in Amsterdam colos and burst or run analytics in hyperscaler regions via direct connect. (peeringdb.com)

Practical next steps (fast checklist)

1. Define requirements: capacity (U/rack/kW), latency SLA, certifications, expected growth, and budget.
2. Shortlist 3 providers (e.g., Digital Realty/Interxion, Equinix, Iron Mountain or EvoSwitch/NorthC). (datacentermap.com)
3. Ask each for: site factsheet (PUE, available MW, redundancy), carrier list, AMS‑IX/NL‑IX presence, cross‑connect prices, and sample SLA. (peeringdb.com)
4. Run a short latency test (ping/traceroute) to candidate sites and to your cloud endpoints.
5. Negotiate trial month or pilot rack and confirm physical access / remote‑hands availability.

If you want, I can:

• Prepare a tailored shortlist (3–4 site suggestions) based on your exact needs (rack count, power density, compliance), or
• Draft an RFP template to send to providers that captures the items above.
