What Is Colocation — The Independent Mid-Market Guide
Colocation is the practice of housing your company’s servers, networking equipment, and storage infrastructure in a professionally managed third-party data center facility rather than in your own office, server room, or corporate data center. The facility provides the physical space, power, cooling, and network connectivity your equipment needs to operate — you own and manage the equipment itself.
As the most commonly misunderstood infrastructure decision mid-market companies face — colocation sits at the intersection of cost, compliance, connectivity, and operational control in a way that neither public cloud nor on-premise infrastructure can match for the right workload profile. This is your independent what is colocation guide — written by an advisor with no financial stake in which provider or infrastructure model you choose.
Consider this your independent colocation review — covering every aspect of what colocation is, how it works, when it makes sense, and when it does not — for mid-market companies in the New York data center market and nationally.
Colocation is the right infrastructure model for mid-market companies with stable predictable workloads, compliance requirements, or cloud bills that have grown beyond what the flexibility justifies. It consistently delivers 40 to 60 percent lower costs than equivalent cloud spend for the right workload profile. Metro Colo Advisory evaluates every NYC provider simultaneously to find the right fit — at no cost to you.
Colocation Definition — The Simple Version
Colocation — often shortened to colo — means you rent space in someone else’s data center. You bring your own servers and networking equipment. The data center provides:
- Physical space — cabinet, cage, or suite depending on your deployment size. Power — dedicated power circuits with redundant backup systems. Cooling — precision air conditioning maintaining optimal operating temperature. Physical security — biometric access controls, 24/7 security staff, and camera monitoring. Network connectivity — access to carriers, internet exchanges, and cloud on-ramps.
- The colocation definition in practice: you maintain full control of your hardware and software while outsourcing the facility infrastructure that most mid-market companies have no business trying to build and operate themselves.
How Colocation Works — Step by Step
Understanding how colocation works requires understanding each component of the relationship between you and the facility.
Step 1 — You select a facility:
Based on your power requirements, connectivity needs, compliance certifications, geographic requirements, and budget. The facility selection decision determines your infrastructure economics for the next three to five years. An independent colocation advisor evaluates every facility that could serve your requirements simultaneously — not just the ones you already know about.
Step 2 — You sign a colocation contract:
Committing to a specific amount of power, physical space, and connectivity for a defined term — typically one to five years. The contract terms — escalation clauses, auto-renewal provisions, minimum power commitments, and early termination fees — are as financially significant as the monthly rate. See our colocation contract guide for a complete analysis of what to look for before signing.
Step 3 — You ship or transport your equipment:
Servers, networking equipment, and storage infrastructure move to the facility. The facility installs your equipment in your dedicated cabinet, cage, or suite. Physical cross-connects to carriers and cloud providers are installed.
Step 4 — You manage your infrastructure remotely:
Once installed you access your equipment remotely — through out-of-band management, remote hands facility staff for physical tasks, and your standard remote access tools. You retain complete control of your hardware and software. The facility manages the physical environment — power, cooling, physical security.
Step 5 — You pay monthly:
Your monthly colocation bill covers committed power, physical space, cross-connect fees, and any remote hands usage. See our colocation pricing guide for a complete breakdown of what goes into a colocation bill and what mid-market companies actually pay.

Colocation vs Cloud — The Honest Comparison
The most important infrastructure decision mid-market companies face is not which colocation provider to choose — it is whether colocation or public cloud is the right model for their specific workload profile. Here is an honest independent assessment.
When cloud wins:
Variable workloads with unpredictable compute demand — cloud’s elastic scaling model is genuinely superior for workloads that spike and contract. Early-stage companies without capital for hardware investment — cloud’s operational expense model avoids upfront hardware costs. Companies without internal IT infrastructure management capability — managed cloud removes the operational burden. Workloads with genuine geographic distribution requirements across many regions simultaneously.
When colocation wins:
Stable predictable workloads with consistent compute demand — companies running the same servers at consistent utilization every month pay 40 to 60 percent less in colocation than equivalent cloud spend over a two to three year period. Companies with compliance requirements — SOC 2, HIPAA, PCI-DSS — where a certified colocation facility provides a stronger documented compliance posture than public cloud for regulated data. High density GPU and AI infrastructure — dedicated high density colocation at DataBank LGA3 runs 40 to 55 percent below equivalent cloud GPU pricing for stable inference workloads. Companies that have outgrown cloud economics — cloud repatriation is the fastest growing segment of the colocation market as stable workload cloud costs reach untenable levels.
The hybrid model:
Most mid-market companies land somewhere between pure cloud and pure colocation. Variable and development workloads stay in cloud. Stable production workloads, regulated data, and high-density compute move to dedicated colocation. The private connectivity between colocation and cloud — through CoreSite’s Open Cloud Exchange, Digital Realty’s ServiceFabric, or carrier-neutral cross-connects — makes the hybrid architecture operationally clean.

Colocation vs On-Premise When to Make the Move
On-premise infrastructure — servers in your own office, server room, or corporate data center — remains the starting point for many mid-market companies. The decision to move to professional colocation is driven by one or more of the following:
Compliance requirements:
SOC 2 Type II, HIPAA BAA, PCI-DSS, and other certifications require significant investment to achieve and maintain in an on-premise environment. A certified colocation facility provides that compliance infrastructure as part of the service — dramatically simplifying your own compliance documentation and audit process. For HIPAA colocation specifically — DataBank LGA3 carries the strongest HIPAA BAA in the NYC metro market and is the primary independent recommendation for healthcare AI workloads requiring both HIPAA compliance and high density GPU infrastructure simultaneously.
Power and cooling limitations:
Standard office power circuits and HVAC systems were not designed for dense server infrastructure. Companies growing their compute footprint consistently hit power and cooling limits in on-premise environments before they hit their compute requirements. Professional colocation facilities are purpose-built for high-density power and precision cooling.
Connectivity requirements:
On-premise infrastructure connects to the internet through commercial carrier circuits — limited bandwidth, single carrier, no redundancy.
Professional colocation facilities — particularly carrier-neutral colocation data centers — provide access to hundreds of carriers, internet exchanges, and cloud on-ramps simultaneously. The network diversity and bandwidth pricing available in a colocation facility is simply not achievable in an on-premise environment.
Operational burden:
Running your own data center means managing power infrastructure, cooling systems, physical security, and facility maintenance alongside your actual IT and business responsibilities. Most mid-market companies have no business managing physical data center infrastructure — it is a distraction from their core operations.
Disaster recovery requirements:
On-premise infrastructure has no geographic separation for disaster recovery. Professional colocation — particularly disaster recovery colocation at a geographically separated facility — provides the redundancy that most compliance frameworks and cyber insurance policies now require.
Types of Colocation — Cabinet, Cage, Suite, and Beyond
Not all colocation deployments look the same. Understanding the different deployment models before engaging any provider prevents mismatches between what you need and what you sign.
Cabinet colocation — 1 to 5 cabinets:
A single standard 42U rack or small number of cabinets in a shared colocation environment. Standard for small to mid-market deployments. Most cost-effective entry point for professional colocation. Physical security is shared with other tenants in the same row or zone. Many providers offer 1U colocation — individual rack unit space within a shared cabinet — for very small or test deployments before committing to a full cabinet.
Cage colocation — 5 to 20 cabinets:
A dedicated fenced enclosure housing multiple cabinets. Physical security separation from other tenants — your cage is locked and accessible only to your authorized staff and approved facility personnel. Standard for mid-market deployments with security, compliance, or operational separation requirements.
Suite colocation — 20 or more cabinets:
A fully enclosed dedicated room with its own power infrastructure, cooling systems, and access controls. Maximum physical security and operational control. Standard for larger mid-market deployments and companies with specific compliance requirements for physical isolation.
High density colocation — specialized facilities:
Standard colocation infrastructure supports 3 to 10 kilowatts per rack — sufficient for traditional enterprise compute. High density colocation supports 10 to 100 kilowatts per rack — required for GPU infrastructure, AI inference workloads, and HPC compute. High density facilities require specialized power distribution and liquid cooling infrastructure that most colocation providers cannot support. DataBank LGA3 in Orangeburg is the primary independent recommendation for high density colocation in the NYC metro market — NVIDIA DGX Ready certified with purpose-built infrastructure for modern GPU deployments.
Wholesale colocation — 500kW and above:
Large-scale dedicated deployments negotiated directly with providers outside standard retail channel programs. Beyond the scope of most mid-market companies — this guide covers retail mid-market colocation.
Colocation Compliance — Why Facility Certifications Matter
For mid-market companies in regulated industries the compliance posture of your colocation facility becomes part of your own compliance posture. Choosing a certified facility dramatically simplifies your internal compliance documentation and dramatically reduces your audit burden.
SOC 2 Type II:
The foundational compliance certification for enterprise colocation. An independent third-party audit of the facility's security, availability, and confidentiality controls conducted annually. Required by most enterprise security programs and strongly preferred by regulated industry clients. All major NYC metro colocation providers — Equinix, Digital Realty, DataBank, CoreSite, and Cologix — maintain SOC 2 Type II certification.
HIPAA Business Associate Agreement:
Required for healthcare organizations, health tech companies, and life sciences firms storing or processing protected health information in a colocation facility. Not all colocation providers execute HIPAA BAAs — and the scope and terms of BAAs vary significantly between providers. DataBank carries the strongest HIPAA BAA in the NYC metro market — and uniquely combines HIPAA BAA capability with NVIDIA DGX Ready certification for healthcare AI workloads requiring high density GPU infrastructure.
PCI DSS:
Payment card industry compliance for companies handling cardholder data. The colocation facility's PCI DSS certification covers the physical environment — power, cooling, physical security. Your own PCI compliance program covers the application and data layer running on your equipment in the facility.
ISO 27001:
Information security management system certification. Relevant for companies with international operations or clients requiring ISO certification. Maintained by Equinix, Digital Realty, DataBank, and CoreSite across their NYC facilities.
The compliance evaluation:
Always request current certifications — not 2022 PDFs. Verify certifications cover the specific services and physical spaces you will use — not just the facility broadly. An independent advisor with current provider compliance documentation can verify posture for your specific requirements before you commit.
Colocation in the NYC Metro Market — What Makes It Different
The New York data center market is the most important colocation market in the United States and one of the most supply-constrained markets in the world. Understanding what makes the NYC metro colocation market different from other US markets is essential before evaluating providers.
- The financial ecosystem: No colocation market in the world concentrates financial trading infrastructure the way NYC does. Equinix NY4 in Secaucus houses exchange matching engines, prime broker cross-connects, and the systematic trading operations of the world’s largest quantitative funds. For financial services companies this ecosystem access is irreplaceable and justifies the premium pricing at NY4. For companies without specific financial trading requirements this premium is not warranted.
- The carrier hotel ecosystem: Manhattan carrier hotels — 60 Hudson Street, 111 8th Avenue, and 32 Avenue of the Americas — are among the most carrier-dense buildings in the world. Hundreds of carriers, ISPs, content delivery networks, and cloud providers maintain presence in these buildings. For companies where carrier density and specific network paths are primary requirements — Manhattan data centers are unmatched globally.
- The three zone structure: The NYC metro market serves different buyer profiles across three distinct zones — Manhattan carrier hotels at premium pricing, the Secaucus campus at mid-market pricing with financial ecosystem access, and the Orangeburg and New Jersey zone at the most competitive pricing with purpose-built high density AI infrastructure. Understanding which zone fits your requirements before engaging providers is the most important step in any NYC colocation evaluation.

The Five NYC Colocation Providers — An Independent Overview
Equinix:
The most connected data center operator in the NYC metro market and the dominant financial ecosystem provider. NY4 is the primary financial trading infrastructure hub. NY5 supports high density deployments. The most expensive option in the NYC market — justified for specific financial ecosystem requirements, not always for standard enterprise deployments. See our Equinix NY4 guide for a full independent analysis.
Digital Realty:
The second largest NYC provider by footprint and the most globally connected. Manhattan carrier hotels at 60 Hudson Street and 111 8th Avenue serve companies with specific carrier hotel requirements. ServiceFabric cloud connectivity is the primary differentiator for hybrid cloud deployments. See our Digital Realty NYC guide for a full independent analysis.
DataBank:
The strongest independent recommendation for AI and high density GPU colocation, healthcare IT requiring simultaneous HIPAA BAA and high density capability, and cost-sensitive enterprise deployments where Equinix and Digital Realty pricing exceeds budget. LGA3 in Orangeburg is NVIDIA DGX Ready certified with purpose-built high density infrastructure. See our DataBank NYC guide for a full independent analysis.
CoreSite:
The strongest independent recommendation for hybrid cloud architecture requirements where Open Cloud Exchange private cloud connectivity delivers meaningful economic benefit. NY3 is newly completed 2025 infrastructure with current generation specifications. More competitive pricing than Equinix for standard Secaucus enterprise deployments. See our CoreSite NYC guide for a full independent analysis.
Cologix:
The most cost-competitive standard enterprise colocation option in the NYC metro market. Parsippany NJ facilities serve cost-sensitive primary deployments and disaster recovery colocation where geographic separation from Manhattan and Secaucus is required. National footprint across Columbus, Dallas, Minneapolis, and Ashburn. See our Cologix NYC guide for a full independent analysis.

When Colocation Makes Sense — And When It Doesn't
Colocation makes sense when:
- Your compute workload is stable and predictable — you run consistent servers at consistent utilization month after month. Cloud’s variable pricing model penalizes you for this stability. Colocation rewards it.
- Your compliance requirements favor dedicated infrastructure — SOC 2, HIPAA, PCI-DSS, and other certifications are easier to maintain and document in a certified colocation facility than in public cloud or on-premise environments.
- You have meaningful IT infrastructure management capability internally — colocation requires someone to manage the hardware and software running in the facility. If that capability exists colocation typically delivers better economics and control than managed hosting.
- Your AWS or Azure bill has become untenable — stable workloads running above $20,000 to $30,000 per month in cloud almost always have a compelling colocation economics case. Cloud repatriation is one of the fastest growing segments of the colocation market for exactly this reason.
- You need specific network connectivity — carrier hotel access, financial ecosystem proximity, or specific cloud on-ramp economics that are not achievable in an on-premise environment.
Colocation does not make sense when:
- Your workload is genuinely variable — if compute demand spikes unpredictably cloud’s elastic model is genuinely more cost-effective than paying for committed colocation capacity that sits idle during low-demand periods.
- You have no internal IT infrastructure management capability — colocation requires hardware management. Without that capability managed hosting or cloud is more appropriate.
- You are at very early stage without capital for hardware — cloud’s operational expense model makes more sense than the capital expense of hardware plus colocation for companies that cannot yet justify infrastructure investment.
- Your geographic requirements are genuinely global and distributed — cloud’s global region model is superior to colocation for workloads that need to be close to users in dozens of countries simultaneously.
How to Choose a Colocation Provider — The Independent Framework
The most common mistake mid-market companies make in colocation evaluation is engaging providers sequentially rather than simultaneously. Here is the correct evaluation framework:
Step 1 — Define your actual requirements:
Power draw in actual kilowatts — not nameplate ratings. Compliance certifications required. Connectivity requirements. Geographic requirements. Budget. Timeline. Most companies overestimate their power requirements and underestimate their connectivity requirements.
Step 2 — Identify every provider that could serve your requirements:
Not just the providers you already know. The NYC metro market has five major providers serving distinct buyer profiles. The right provider for your requirements may not be the most recognized brand name.
Step 3 — Run a competitive evaluation simultaneously:
Submit identical requirements to every potentially qualifying provider at the same time. Competitive pressure is the most powerful pricing negotiation tool available — providers respond differently when they know they are competing.
Step 4 — Evaluate the full cost not just the monthly power rate:
Cross-connect fees, setup costs, remote hands rates, escalation clauses, auto-renewal provisions, and minimum power commitments all have significant financial impact over a three to five year term. See our colocation pricing guide for the complete cost breakdown.
Step 5 — Negotiate with benchmark data:
Knowing what comparable deployments actually pay — not what list pricing says — is the most valuable negotiating asset available. An independent advisor with current benchmark data across every provider in your target market provides this context before you respond to any proposal.
For companies in the early stages of data center site selection — evaluating which zone and which provider fits their specific requirements — this framework produces meaningfully better outcomes than engaging providers directly without competitive context.
Why Independent Advisory Changes Colocation Outcomes
Metro Colo Advisory is an independent colocation broker — we work for you, not for any provider. Think of us the way you’d think of a buyer’s agent in real estate. Our commission comes from the provider you choose, paid only when a deal closes. There is no cost to you.

Frequently Asked Questions — What Is Colocation
What is colocation and how does it work in simple terms?
Colocation means renting space in a professionally managed data center to house your company’s servers and networking equipment. The facility provides power, cooling, physical security, and network connectivity. You own and manage your equipment. The facility manages the physical environment. You pay monthly for the space and services you use. Metro Colo Advisory evaluates whether colocation fits your specific requirements at no cost.
What is the difference between colocation and cloud computing and which is cheaper?
In colocation you own your hardware and pay a monthly fee for space, power, and connectivity in a third-party facility. In cloud computing you rent virtual compute resources from a provider — Amazon, Microsoft, or Google — and pay based on usage. Colocation typically delivers 40 to 60 percent lower costs than equivalent cloud spend for stable predictable workloads over a two to three year period. Cloud is more cost-effective for variable workloads with unpredictable compute demand. Metro Colo Advisory models the colocation vs cloud comparison for your specific workload profile at no cost.
What is the difference between colocation and managed hosting and which should I choose?
In colocation you own your hardware and manage it yourself remotely. In managed hosting the provider owns and manages the hardware on your behalf. Colocation provides more control and typically better economics for companies with internal IT management capability. Managed hosting removes the operational burden for companies without that capability. Metro Colo Advisory evaluates which infrastructure model best fits your team’s capabilities at no cost.
How much does colocation actually cost per month for a mid-market company?
Colocation pricing varies significantly by provider, market zone, deployment size, and power density. In the NYC metro market Manhattan carrier hotel deployments command a 20 to 40 percent premium over comparable Secaucus deployments. Standard enterprise Secaucus deployments vary meaningfully between Equinix NY4 at the high end and CoreSite NY2 and DataBank at more competitive pricing. The only way to know what your specific deployment should cost is running a competitive evaluation with current benchmark data. See our colocation pricing guide for full context. Metro Colo Advisory delivers current benchmark pricing for your specific deployment at no cost.
What is a carrier-neutral colocation facility and why does it matter?
A carrier-neutral colocation facility allows you to connect to any carrier, ISP, or network provider in the building without restriction. This carrier neutrality creates competitive bandwidth pricing — carriers compete for your business rather than one carrier having a captive relationship. All five major NYC metro colocation providers operate carrier-neutral facilities. Manhattan carrier hotels like 60 Hudson Street and 111 8th Avenue are particularly carrier-dense with hundreds of carriers maintaining presence in the building. Metro Colo Advisory evaluates which carrier-neutral facility best fits your connectivity requirements at no cost.
What compliance certifications should my colocation facility have for SOC 2 or HIPAA?
At minimum look for SOC 2 Type II — the foundational enterprise security certification. For healthcare organizations add HIPAA BAA capability — DataBank carries the strongest HIPAA BAA in the NYC metro market. For financial services add SOC 1 Type II and PCI DSS as relevant. Always request current certifications covering the specific spaces and services you will use — not legacy documentation covering the facility broadly. Metro Colo Advisory verifies compliance posture for your specific requirements at no cost.
What is high density colocation and do I need it for AI or GPU workloads?
High density colocation supports power densities above 10 kilowatts per rack — required for GPU infrastructure, AI inference workloads, and HPC compute. Standard colocation supports 3 to 10 kilowatts per rack. If you are deploying GPU servers for AI workloads you need a facility that supports the power density your hardware requires. DataBank LGA3 is the primary independent recommendation for high density colocation in the NYC metro market — NVIDIA DGX Ready certified supporting air cooling to 35kW per rack and liquid cooling to 100kW per rack. Metro Colo Advisory evaluates high density colocation options for your specific GPU configuration at no cost.
What is the difference between colocation and a data center?
A data center is the physical facility — the building with power infrastructure, cooling systems, and network connectivity. Colocation is the service of renting space within a data center facility. All colocation is in a data center — but not all data centers offer retail colocation to mid-market companies. Some data centers are dedicated to a single tenant or built for wholesale deployments of 500kW and above. Metro Colo Advisory evaluates which type of colocation deployment best fits your requirements at no cost.
Should I use an independent colocation broker or go direct to providers like Equinix?
Use an independent colocation broker — for the same reason you would use a buyer’s agent when purchasing real estate. The broker is paid by the provider not by you. The commission exists whether you use an advisor or not. Going direct means negotiating without benchmark data against a sales team that negotiates every day. Independent colocation advisory costs you nothing and consistently produces better facility selection, pricing, and contract terms than direct negotiation. Metro Colo Advisory provides this independent advisory at no cost.
