What is Colocation?
The term colocation or ‘colo’ is used to describe the process of locating privately-owned servers and networking equipment in a third-party data facility. Rather than purchasing and operating your own facility, you lease space, which may be rack, cabinet, cage, or room, in a professionally operated data center.
Read more about what is colocation in detail.
Key Features of Colocation
- You own the hardware.
- The plant offers bandwidth, power, cooling and physical security.
- You have control over your systems but use the infrastructure of a bigger provider.
- Colocation is the most suitable where the company needs to have control of its IT equipment but will not own the data center so that they will not have to spend huge sums of money in constructing their own data center.
What is a Data Center?
A data center is a special purpose building that is built to contain computer hardware, like servers, storage systems and networking devices. These facilities are designed to be highly available, redundant, and secure, and are the workhorse of digital operations in the present day.
Be it a hyperscale data center run by tech giants or a local center that caters to the needs of local businesses, the definition of data center will always be the same: it is a central processing, storage, and distribution facility of data.
Meaning of Data Center
To explain further, the definition of data center is not limited to physical infrastructure. It encompasses:
Operational Reliability
Operational reliability is the capacity of a data center to operate day and day out. This is by way of the introduction of redundancy systems that serve as backups to avoid periods of downtime. Redundant power sources are significant, and they may include several uninterruptible power supply (UPS) devices, backup power generators, and a connection to alternative power grids. A failure of any single power source triggers the activation of another source so that servers and other equipment do not go dead.
Redundant network connectivity also provides data centers with operational reliability. This is the application of multiple internet service providers (ISPs) and various fiber optic cable paths. When a network route is disabled or an ISP goes offline, traffic will automatically be redirected via another route without causing any disruption to the services. These redundancies are meant to remove single points of failure, which means that when a component fails or an external incident occurs, the data center can absorb the impact without compromising the services that it offers.
Security Protocols
Security measures refer to the actions that are implemented in order to secure a data center against unauthorized access and possible threats, both physical and digital. One of the most basic security layers is physical access control, which begins with perimeter fencing, security guards and surveillance cameras. Within the facility, only authorized staff should enter the building, which can be achieved using keycard, biometric, fingerprint, or retinal scans, and multi-factor authentication.
Besides physical, cybersecurity is the most important in securing the data itself. This consists of firewalls, intrusion detection system (IDS) and anti-malware software to protect against network attacks. Security audits, vulnerability scans and penetration testing are performed regularly to discover and correct weaknesses.
Scalability
Scalability is the capability of the data center to expand and meet the growing demands of the business. It is one of the basic attributes that enable a company to extend its operations without the need of making a total overhaul of its IT infrastructure. A scalable data center is built to scale in the future, using modular designs so it can easily add new servers, storage and networking devices.
On-demand expansion of resources is valuable to businesses with intermittent or quickly evolving data needs. A company can begin with a smaller operation instead of investing in a huge expensive infrastructure at the start, then add capacity as it grows. This is a cost-efficient and efficient pay-as-you-grow model.
Compliance
Compliance is a term that describes the compliance of a data center with different industry standards, governmental regulations, and best practices. These standards are not only legally required in most instances but also indicators of an investment in security, privacy, and quality. Information security management based on ISO 27001 industry standards and data security, availability and confidentiality based on SOC 2 (Service Organization Control) offer guidelines on sound data management practices.
In addition, data centers are required to meet certain rules depending on the nature of information they manage. As an example, medical information data centers in the United States must comply with HIPAA (Health Insurance Portability and Accountability Act) that requires high security and privacy levels on the protected health information.
In a sense, a data center is the virtual soul of an organization, which can facilitate cloud computing, enterprise resource planning (ERP), etc.
Colocation vs Data Center: Which One to Choose?
In making the decision of whether to use colocation or a data center solution, you should consider the following:
| Feature | Colocation | Data Center |
| Hardware Ownership | Business owns it | Provider owns it |
| Control | High | Low to Medium |
| Infrastructure | Provider manages | Provider manages |
| Cost | Medium | Low to High |
| Scalability | Limited | High |
| Best For | Businesses needing hardware control | Businesses wanting fully managed solutions |
To most companies, a hybrid model in which core systems are colocated and cloud data centers are used as a scalability solution is the best of both worlds.
Benefits of Colocation
Reduced Capital Expenditure
A migration to a data center service will eliminate the requirement to make a large capital investment. Businesses can take advantage of the existing facilities of a service provider, as opposed to investing huge amounts of money in constructing or expanding a personal data center, including the cost of land, construction, hardware and infrastructure such as power and cooling.
This reduction of capital expenditure (CapEx) to operational expenditure (OpEx) enables businesses to pay a fixed, continuous fee, which leaves capital available to use in the business, research, and development. This model is specifically helpful when working with a start-up and small to medium-sized enterprises that might lack the funds needed to invest in a large infrastructure project. Cantech’s Small business colocation provides these organizations with access to secure, high-performance data center facilities at a fraction of the cost of building and maintaining their own.
Improved Availability and Reliability
Data centers provide better uptime and performance through the use of enterprise infrastructure and professional management. To ensure that they do not have single points of failure, they use redundant systems to support power, cooling, and network connectivity so that services stay online when a component fails or power goes off.
Most facilities also have numerous links to various power grids and ISPs to ensure that they are running at all times. This degree of redundancy can be too costly or complicated to be handled by an individual company, and a data center can be a more sound and dependable way of supporting mission-essential activities.
High-Speed Connectivity
High-speed accessibility is one of the features that data centers are designed with. They are stationed in urban or suburban regions with access to large fiber optic networks and do direct peering with other internet service providers (ISPs).
This enables companies to enjoy low latency and high data bandwidth which is crucial when using cloud computing, mass data transfer and real time applications. By using a data center, organizations are able to overcome the constraints of a typical office network to offer a stronger and more effective connection to operations and services provided.
Disaster Recovery and Business Continuity Support
Data centers are a highly important part of business continuity planning and disaster recovery (DR). They offer an off-site backup storage area, which is secure. When a fire, flood, or other calamity strikes the main office of a firm, the business can easily redirect to the resources within the data center, reducing downtime and loss of data.
To assist businesses to get online within a short period, several data centers provide dedicated DR services such as warm sites and hot sites. This will be essential in keeping operations going and cushioning against severe financial and reputational losses.
Compliance-Ready Infrastructure
In regulated business, data centers offer infrastructure that is compliant. These plants are designed and maintained to high-industry standards and governmental requirements, including the HIPAA standards concerning healthcare data, the PCI DSS standards addressing credit card data, and GDPR standards relating to personal data in Europe. They are subjected to periodic third party audits and keep records to demonstrate their compliance to these standards.
Mid-sized enterprises, SaaS vendors, and financial institutions that seek control, performance, and compliance- without the burden of managing a facility- often rely on enterprise colocation servers to achieve secure and scalable infrastructure.
How Does Colocation Work?
It is important to know how does colocation work in order to determine the suitability of colocation to your business.
Step-by-Step Breakdown
- Equipment Procurement: You buy your own servers and networking equipment and assemble them yourself.
- Facility Selection: Select a colocation provider by location, connectivity, compliance and support.
- Installation: Physical installation refers to the physical placement of your equipment in the racks or cages of the provider.

How Does Data Center Work?
To understand how does data center work, let’s break it down into core components:
Power Infrastructure
The best backbone of any data center is its well-developed power infrastructure, which serves to sustain its operations during outages or grid failure. This involves Uninterruptible Power Supplies (UPS) which offer instant backup during interruption of power, diesel-powered generators in case of long term power outage, and redundancy of power circuits to eliminate single points of failure. These systems together will ensure high availability and reliability which are essential to mission critical applications and 24/7 uptime.
Cooling Systems
To ensure the high operation rates and to prevent the wear out of hardware, data centers install highly developed cooling systems that control the temperature and humidity. Strategic placement of precision air conditioning units and liquid cooling technologies dissipates heat that arises as a result of the dense placement of servers. Cooling efficiency is not only crucial to ensuring a longer life of equipment, but also to minimizing the usage of energy, which is a critical part of ensuring both stability and sustainability in operations.
Network Connectivity
The digital arteries of a data center consist of high-speed and redundant fiber connections that interconnect it with the internet service providers (ISPs), cloud service providers and enterprise networks. These connectivity solutions allow high-speed data transfer, minimal latency, and effortless access to hosted applications and services. Data centers have a variety of carriers and peering options to ensure a strong connection that supports real-time analytics to delivering content around the globe.
Physical Security
Servers are hardened with multi-layered physical security measures to ensure unauthorized access and protection of vulnerable equipment. The biometric authentication systems, surveillance cameras, security guards and mantraps (secure entry vestibules) operate together to monitor and regulate access. These are necessary steps to meet industry best practices and mitigate external risks as well as insider risks.

FAQs
What are the 4 Types of Data Centers?
The 4 main types of data centers are Enterprise Data Centers, Colocation Data Centers, Managed Hosting Data Centers, and Cloud Data Centers. Enterprise data centers are owned and operated by a single company for internal use. Colocation data centers rent space to multiple businesses who bring their own hardware. Managed hosting data centers handle everything on behalf of the client, while cloud data centers deliver computing resources virtually over the internet.
What are the Disadvantages of Colocation?
While colocation offers many benefits, it does come with some limitations. You are still responsible for purchasing, maintaining, and upgrading your own hardware, which can be costly over time. Remote management can also be challenging since your team needs to either access systems remotely or travel to the facility for hands-on work. Additionally, if the colocation provider experiences a major outage or connectivity issue, your business operations can be directly affected.
What is an Example of a Colocation Data Center?
A good example of colocation in action is an average e-commerce business that owns its servers but does not want to manage a full data center facility. Instead of building their own infrastructure, they rent rack space at a professional colocation facility like Cantech’s colocation centers in Mumbai, Noida, or Pune, where their servers are kept secure, connected, and running 24/7 without any facility management burden on their team.
