The role of the data centre has changed drastically over recent years.
As the rapid rise of AI, the cloud, and virtualisation continue to shift the information technology landscape, data centres have had to adjust to keep up with new processing demands.
In this article, we look at what a data centre is, how they work, and why many businesses are making them central to their day-to-day operations.

The most basic definition of a data centre is simply a facility that a business uses to house its IT equipment.
While you could place your network servers in a corner of your own office, many modern businesses require their mission-critical IT systems to be secure, reliable and easily accessible.
This involves a significant amount of facilities infrastructure, which includes backup generators, cooling systems, power supplies and more. It requires a level of capital investment beyond the reach of most SMEs.
For that reason, many businesses will make use of the colocation services provided by third-party data centres, such as ourselves.
Colocation simply means placing your own IT equipment in pre-built racks in a data centre. This isn’t just servers, but associated equipment like storage devices, network switches and firewalls.
In doing so, you can let us take care of running the facility itself, while you concentrate on running your IT systems.
As previously mentioned, the data centre will also provide the infrastructure needed to function, including:
At Pulsant, we own and manage all these elements. We also host multiple businesses within each of our data centre facilities, so we’re able to keep costs at a minimum for you.
At Pulsant, reliability is built into every layer of our data centre infrastructure. We use multiple levels of redundancy to ensure uninterrupted service—even during unexpected failures or maintenance.
All systems are routinely tested to meet the highest standards. For instance, we regularly simulate full power outages to verify that generators take over without disruption—guaranteeing your services stay online even during real emergencies.
The most important part of supporting all this infrastructure is, of course, the people.
Maintaining the building fabric, the power, cooling sub-systems, and the security of the facilities needs knowledgeable staff.
As with the physical elements of the data centre, recruiting and retaining this team of people would be prohibitively costly for many businesses. With your equipment housed in a data centre, however, you have experienced engineers working for you 24/7.
Typically, businesses find that colocation hosting improves business operations, cuts capital costs and increases the reliability and availability of service.
In our data centres, you can occupy everything from a shared rack up to your own secure cage. You can even have a dedicated private room within the facility, depending on your needs.
Our data centre colocation services are priced according to the physical space that your servers take up in the data centre and the amount of power they draw. Additional charges may be made for networking provision and for any server maintenance tasks you ask our engineers to carry out.
As your IT needs grow, your data centre footprint can scale accordingly, with none of the up-front capital expense you would need to expand your on-premises server room.
There are potential downsides to consider when moving your equipment into a third-party data centre. One of the main issues is the distance from your own offices.
If using our on-site staff isn’t suitable and you need to send your engineers to attend to your servers, the distance and associated travel time needs to be considered.
That is why our data centres are scattered across the country and include excellent transport links.
Our colocation data centre estate includes enterprise-class facilities at:
All of our data centres are designed to offer the same high levels of enterprise-class service, allowing you to choose a facility that is geographically convenient for you.
A great data centre should measure itself against global standards.
At Pulsant, we hold independently verified certifications in multiple standards, including:
These certifications are only awarded after rigorous independent auditing and show our commitment to the highest levels of service and security.
In a highly regulated industry, you may need to show compliance with some or all of these standards yourself. Hosting your systems in a certified data centre provides an essential tick in the box.
Another key benefit of moving your IT into our data centres is geographical resilience.
By mirroring your systems between geographically separated data centres, you can make sure that your systems continue functioning in the event of a localised disaster. This wouldn’t be the case if your systems were all housed in a room in your own office.
For this reason, even businesses that run their IT from their premises often use a third-party data centre as a backup. The disaster recovery options provided by dispersed data centres should form a key part of the business continuity planning of any organisation that relies on mission-critical IT systems.
All our data centres are connected by our multi-gigabit core network, allowing the fast and reliable transfer of data between the facilities.
Colocation is only one way to use a data centre.
Many organisations find it makes commercial sense to outsource IT management entirely to service providers such as ourselves.
In addition to data centre colocation, we provide public and private cloud services and a range of managed server services, all hosted from within our data centres.
Should your server estate become too large or complex for you to continue to manage yourself, you could migrate to one of our managed server solutions. This could be either on dedicated hardware we manage for you or on shared infrastructure in our Enterprise Cloud service.
Whether you’re just starting to explore colocation or looking to optimise an existing setup, Pulsant’s UK-wide network of enterprise-grade data centres gives you the flexibility, security, and scale your business needs to thrive.
From colocation to fully managed cloud infrastructure—we’re here to help you build the right solution for your business.
