Colocation

What is Data Centre Colocation?

Data centre colocation, often referred to simply as “colo,” is a service provided by data centres where businesses can rent space, power, cooling, and security for their servers, networking equipment, and other hardware. Instead of building and maintaining an in-house data centre, companies can colocate their hardware in a third-party facility, gaining access to the infrastructure and support needed to ensure their IT operations run smoothly.

How does Data Centre Colocation work?

In a colocation arrangement, businesses place their servers and networking equipment in a data centre owned by a colocation provider. The provider offers the physical space—typically in the form of racks, cabinets, or cages—as well as the necessary power, cooling, and physical security to keep the equipment running 24/7. Additionally, colocation facilities often provide robust internet connectivity options, allowing businesses to connect to their servers remotely.

Here’s a step-by-step breakdown of how it works:

Choosing a Colocation Facility: A business selects a colocation provider based on factors like location, cost, connectivity options, and the facility’s ability to meet their specific needs.

Deploying Equipment: The business ships its servers and networking equipment to the colocation facility, where it is installed in the allocated space.

Connectivity Setup: The colocation provider connects the equipment to the facility’s power and cooling systems, as well as to the internet and any other necessary networks.

Ongoing Management: While the colocation provider handles the physical infrastructure, the business retains control over the management and maintenance of its own equipment, including software updates, backups, and monitoring.

Scalability: As the business grows, it can rent additional space or upgrade its connectivity options as needed.

Pros and Cons of Data Centre Colocation

Pros:

Cost Efficiency: Colocation allows businesses to avoid the capital expenses associated with building and maintaining a data centre. Instead, they pay a predictable monthly fee for the services they need.

Scalability: Colocation facilities offer flexible options for scaling up or down, making it easier to adjust to changing business needs without significant upfront investments.

Security and Reliability: Colocation providers typically offer robust physical security, redundant power supplies, and advanced cooling systems, ensuring high availability and protection for critical infrastructure.

Connectivity: Colocation centres often provide access to multiple carriers and high-speed internet connections, offering businesses a choice of network providers and enhanced connectivity options.

Cons:

Initial Setup Costs: Although cheaper than building a data centre, there are still initial costs involved in transporting and installing equipment at the colocation facility.

Ongoing Management: While the provider handles the physical infrastructure, businesses are still responsible for managing and maintaining their own equipment, which can require in-house expertise.

Location Dependency: The physical location of the colocation facility can impact latency and connectivity, making it important to choose a site that aligns with business needs.

Limited Control: While businesses retain control over their hardware, they are still dependent on the colocation provider for the physical environment, which may limit certain operational decisions.

Is Data Centre Colocation cheaper than Cloud?

The cost comparison between colocation and cloud services depends on various factors, including the scale of operations, specific business needs, and the duration of use.

Colocation: Generally, colocation can be more cost-effective for businesses with consistent, high-level demands that require dedicated hardware. The predictable costs and long-term savings on capital expenditures can make colocation appealing, especially for large enterprises.

Cloud: On the other hand, cloud services offer flexibility and the ability to scale resources up or down quickly. For businesses with variable workloads or that require rapid deployment, the cloud can be cheaper in the short term, though costs can rise as usage increases.

In essence, colocation tends to be cheaper for businesses with stable, long-term infrastructure needs, while the cloud is often more cost-effective for those requiring agility and scalability.

What to look for when choosing a Colocation centre?

When selecting a colocation centre, several key factors should be considered to ensure it meets your business needs:

Location: Proximity to your business operations can reduce latency and facilitate easier access to your equipment. Additionally, consider the site’s geographical stability, particularly regarding natural disasters.

Security: Evaluate the physical and cyber security measures in place, including access controls, surveillance, and fire protection systems.

Connectivity: Check the availability of multiple carriers, the quality of internet connections, and the facility’s ability to meet your networking needs.

Scalability: Ensure the facility can accommodate future growth, whether through additional space or upgraded services.

Redundancy and Reliability: Look for features like redundant power supplies, backup generators, and advanced cooling systems that ensure continuous uptime and minimize the risk of outages.

Support and Services: Consider the level of support provided by the colocation centre, including remote hands services, monitoring, and maintenance options.

Cost Structure: Understand the pricing model, including any potential additional charges for power, connectivity, or support services, to ensure it aligns with your budget.”
