Comparing the total cost of ownership of building your own data center vs.
buying third-party colocation services
Executive Summary
As businesses grow, the need for reliable and scalable data center space to colocate IT
infrastructure also increases. Any data center or power downtime can have crippling effects on a business in the form of decreased productivity, customer churn and lost revenues. Successful businesses often outgrow their own in-house computer and telecom room quickly. They also require suitable environments to support software development, testing, QA and production applications. Furthermore, as businesses target enterprise customers, the need for industry compliance and security increases.
It is important to perform a comprehensive analysis of the costs, risks, and opportunities of building an in-house data center versus buying colocation services before expanding your data center.
Build vs. Buy Colocation
Uptime Institute’s 2015 Data Center Survey showed that colocation service providers are expanding more rapidly than enterprise data centers. The reason behind this is that many
enterprise data center workloads are migrating out of private, single-tenant data centers. More and more enterprise IT leaders are finding it easier to outsource their workloads to colocation and cloud providers.

DATA CENTER SPENDING INCREASES (2014—2015)
Building an in-house data center is expensive. In addition to tenant improvements to raw space, a company must consider the cost of bringing in more utility power and new carriers into their own data center. Also, installing new uninterruptible power systems (UPS), DC battery plants, diesel generators and HVAC systems to cool the servers, storage and networking equipment can be prohibitively expensive. These capital expense (CapEx) costs can add up quickly. Finally, hiring experienced data center personnel adds to the expense and takes resources away from a company’s core business.
In today’s highly competitive and technology-driven environment, businesses are increasingly looking to either build or outsource their physical data center environments.
Renting space from a colocation provider may offer significant savings versus building a data center in-house, because a colocation provider has the economies of scale of serving multiple customers. Using a colocation provider can also be more cost-effective when a business needs to scale over time.

Uptime Institute Tier Classifications
Tier 1: Composed of a single path for power and cooling distribution, without
redundant components, providing 99.671% availability.
Tier II: Composed of a single path for power and cooling distribution, with
redundant components, providing 99.741% availability.
Tier III: Composed of multiple active power and cooling distribution paths,
but only one path active, has redundant components, and is concurrently
maintainable, providing 99.982% availability.
Tier IV: Composed of multiple active power and cooling distribution paths, has
redundant components, and is fault tolerant, providing 99.995% availability.
The Uptime Institute’s research has also provided an estimation of the median costs of building facilities according to their tier structure. What transforms a raw space into a data center is the installation of utility power, redundant power systems and cooling. Data centers are often sized
by the amount of protected electrical capacity of the facility measured in kilowatts (kW). The space required for power and mechanical needs grows incrementally based on the Tier level you decide upon. For example, Tier I and Tier II data centers can require a ratio of 1 to 1 support space, reducing actual allowed space for IT footprint. A Tier IV data center can require up to 3 to 1 of the space required to facilitate the IT footprint. Below are the Uptime Institute’s cost estimates for building a data center broken down by three components:
The “kW” Cost Component by desired level of functionality Tier I: $11,500/kW of redundant UPS capacity for IT Tier II: $12,500/kW of redundant UPS capacity for IT Tier III: $23,000/kW of redundant UPS capacity for IT Tier IV: $25,000/kW of redundant UPS capacity for IT
Based on its research, the Uptime Institute has provided guidelines for Tier classifications and estimated the costs for building data centers. According to their research, the primary drivers of data center construction cost are the costs of power and cooling capacity to a data center.
Build vs. Buy Colocation Comparisons
Below we will compare the costs of 1) building a single tenant data center and 2) renting space from a retail colocation provider. The cost assumptions are based on matching the material, operations, and maintenance programs of a TIER II colocation provider. We also include the ongoing operational costs over a 5-year period. These comparisons assume a build option with the load at 40% of capacity with room for growth, utility costs of $.08 per kWh and a 2.0 Power Usage Effectiveness (PUE), and an average 5 mile local loop/fiber cost of $150 per mile per strand vs. cross connects. Note that while many colocation operators with deep expertise in power efficiency and management can maintain a PUE of 1.3 to 1.5, building a single-tenant facility that is relatively small will result in a higher PUE. We have chosen to be extremely conservative in using a PUE assumption of 2.0.
The “Computer Room” Component in all cases is $300/sq. ft. of computer floor and this
cost must be added to the “kW cost” shown above.
The “Empty Space” Component is added to the “kW cost” above at $190/sq. ft. Cost Examples of Building a Data Center In-house
Based on the Uptime Institute benchmark costs, building data centers can be expensive. For example:
Tier II level facility with 160 racks at 5.0 kW/rack (800 kW of UPS-protected power) @ 5.0kW/rack. (5,000 sq. ft. X $300/sq. ft.) + (800 kW x $12,500/kW) = $11.5 million
Tier III level facility, with 160 racks at 10.0 kW/rack (1,600 kW of UPS-protected power) @ 10.0kW/rack. (5,000 sq. ft. X $300/sq. ft.) + (1,600 kW x $23,000/kW) = $38.3 million
Small Data Center (1,000 square feet)
Tier II level facility with 32 racks at 5.0 kW/rack (160 kW of UPS-protected power) @ 5.0kW/rack. (1,000 sq. ft. X $300/sq. ft.) + (160 kW x $12,500/kW) = $2.3 million
Tier III level facility, with 32 racks at 10.0 kW/rack (320 kW of UPS-protected power) @ 10.0kW/rack. (1,000 sq. ft. X $300/sq. ft.) + (320 kW x $23,000/kW) = $7.7 million
Large “Telco Room” (500 square feet)
Tier II level facility with 16 racks at 5.0 kW/rack (80 kW of UPS-protected power) @ 5.0kW/ rack. (500 sq. ft. X $300/sq. ft.) + (80 kW x $12,500/kW) = $1.2 million
Tier III level facility, with 16 racks at 10.0 kW/rack (160 kW of UPS-protected power) @ 10.0kW/rack. (500 sq. ft. X $300/sq. ft.) + (160 kW x $23,000/kW) = $3.8 million

Construction
Through the phases of planning, engineering, building, and completion, a typical data
center for single tenant use could take 12-24 months to be move in ready. Existing
colocation providers can have spaces move in ready within weeks, a much shorter time
frame to manage.
Core Business and Staffing
Building a data center means a company will need to shift time, knowledge, expertise, and
additional personnel resources away from their core business to understand the specialized
needs in a data center such as power, cooling, fire suppression, security, maintenance and
local/environmental codes.
Costs to Build In-House Data Center
Building your own in-house data center is not a walk in the park. You need to make an
informed decision about the feasibility of building one versus colocating your workloads
to a colocation provider. An in-depth analysis of the costs, risks, and opportunities
corresponding to each option helps uncover hidden costs:

Ongoing Support
Businesses must also consider not only the initial startup costs involved with construction
and acquisition of real estate, but also the ongoing costs of power, heating and air
conditioning, along with the security and maintenance of these physical assets.
Scalability
A life cycle of 10 or more years is expected when building a single tenant data center. This
may lead to initial overbuilds that adds to the bill: additional capital, infrastructure, and
energy consumption costs. If the data center is too big, the cost of each rack will be higher.
If the data center is too small, the business will run out of space too soon and lose the
cost-saving benefits through economies of scale. Colocation leases can be made for much
shorter time frames, and allow a business to grow or reduce their footprint as needed.
Colocation options typically allow capacity to be added or removed quickly and cost
effectively.
Shared Cost Structure
In a single tenant data center, all of the costs of the space, power, and environmental
infrastructure are absorbed by the user. A colocation service provider allows its clients to
share in the lower fixed costs of facility management, maintenance, security and costs of
infrastructure.
Connectivity
Building a single tenant data center can add additional costs of connectivity from carriers
and ISPs by adding fiber and local loop charges. This can also extend the timeline for the
facility to become fully operational. Colocation providers typically have carrier pops located
within their premises that provide redundancy and access to their networks without
Certifications
Another cost that needs to be accounted for is the cost of certifications as well as the
requirements and processes that need to be in place for certifications such as SSAE16 and
HIPAA.

Conclusion
Building an in-house data center is an expensive undertaking especially when you consider
the total cost of ownership over the next five years. Buying colocation services from
a third-party service provider is more cost-effective than building your own. Based on
estimates by the Uptime Institute, colocating can be 19%—64% more cost-effective than
building an in-house Tier 2 data center.
