What are the differences between a data centre in London and ‘the cloud’?

The average business manages approximately 162.9 TB of data. This data includes sensitive company information such as financial data, long-term business plans, client interactions, and applications that help your business manage its daily operations. Just as important is the employee data that it stores, including banking information, national insurance numbers, and personal addresses.

Because there’s so much sensitive information that a company stores within its servers, security and confidentiality are the top priority.

Read on to learn why Cloud computing alone is insufficient and get some reasons why a data centre London location is vital for your needs.

The pros and cons of cloud storage

Many organisations have begun to eliminate on-site data storage in recent years and switch to cloud-based systems. This may seem like a good idea at first, due to the convenience of the cloud. It can be accessed from any device in any location, in addition to backing up data automatically.

Additionally, people like to use the cloud because it requires no additional hardware in the workplace. You don’t need to store or maintain physical servers on-site when everything is based on the internet.

But is the convenience worth the risk? Many experts say that cloud computing has far too many disadvantages to be a viable alternative to private storage.

Your sensitive information is always at risk when it’s in the cloud. While there are ways that you can secure your data in the cloud, it always will be vulnerable to malware and hackers by virtue of being on a public storage system. The fact that it is public storage also means that the cloud service provider will have direct access to assets containing your sensitive data, which can be a legal issue in some cases.

Data on the cloud is also only accessible with an internet connection. If your connection goes down, you won’t be able to recall any data until it comes back up again. This can impact your productivity.

What makes a data centre superior?

Luckily, data centre colocation provides you with all of the benefits of cloud storage with far fewer risks.

Colocation centres store your information off-site, in a secure facility. You also don’t need to store and secure hardware in your own premises since it will all be held at the data centre.

Maintenance of hardware will also be handled by our professionals. You don’t need to worry about getting it upgraded or replacing broken equipment. Our experts will take care of the nuts and bolts for you so that you can focus on your core business.


As touched upon before, colocation is a secure, robust alternative to cloud computing. Not only will all of your information be under virtual lock and key so unauthorised users can’t access it, but the hardware that it’s stored on will also be under physical lock and key.

Individual attention

Cloud computing services often have unreliable customer service. Many of the large cloud service providers offer purely unmanaged services, meaning all setup and ongoing operational responsibilities will fall to the user. The business is in full control of their data, and if a problem occurs, they’re left to fix it on their own. Third party management and consultancy services can be extremely expensive.

As you can imagine, this is extremely problematic for many users. They aren’t equipped to deal with problems that may emerge and therefore are more likely to lose data (or have it stolen). They wind up leaving it susceptible to malware by mistake or find themselves locked out of their system with no real customer support to fall back on.

London data centres are committed to being there to help you secure and access your critical systems. Support enquiries are responded to promptly. Tickets and phone calls allow for immediate assistance from one of our expert representatives, ensuring you have access to all that you need.

Fully managed services

Finally, London data centres can fully manage your systems for you if required. System updates will be automatically installed and supervised by professionals. You don’t need to worry about backups and maintenance in-house; the services that you outsource will take care of everything for you.

Service continuity is a priority at our data centres. If one system goes down, another can be ready and waiting to take its place, providing you with guaranteed 24-hour access to your information.

Why a colocation centre will help your business with data management

We’re living in the information age where data drives the business world.

As companies expand, so do the requirements they place on their data. Businesses are looking for cost-effective, secure solutions for storing and managing their data. While many organisations still use in-house facilities, data centres continue to gain in popularity every year.

In fact, experts are predicting data centre spending to reach $200B in 2021.  

Many data centres offer colocation as their core service. This allows companies to lease space within a larger shared facility.

When it comes to data management, a colocation centre is a secure and affordable solution. Keep reading to find out more.

What is a colocation centre?

A colocation data centre is a physical facility used for data storage. This means companies lease space within the facility to house their critical IT infrastructure.

Colocation centres offer power, cooling, and security. This provides companies with a robust, turnkey solution for their data storage needs.

Included in most colocation services are network connectivity, physical security, powerful cooling, and resilient power delivery.

These facilities are multi-tenant accessible. Depending on their needs, businesses can select from a variety of scalable solutions.

Colocation centres include cabinets, cages, and suites for housing equipment. Clients can access the facility, outsourcing the location and security to the service provider.

There are two main types of colocation centres – wholesale and retail.

Retail colocation

In the retail model, a business leases space inside a colocation centre, usually a rack or cabinet. Power is supplied at a threshold, and the amount you pay depends on your consumption.

Retail colocation is mainly used by startups, SMEs and government agencies.

Retail colocation is a turnkey service, meaning you can just turn up with your hardware and get setup. The data centre provides the rack(s), power, PDUs, network connectivity and IP addressing.

Wholesale colocation

Wholesale colocation is geared towards large corporations and service providers. Because of this, it’s a more complete solution. Wholesale colocation provides organisations with larger spaces away from other tenants, and is generally sold as technical space in square feet, or by available total power in the space.

Having your data storage facilities separate from other tenants helps ensure security. Costs for wholesale colocation depend on your power usage and space requirements.

Wholesale space is generally a more hands on experience, for businesses with lots of in-house technical know-how. This approach offers a greater level of economy at a larger scale, by committing to a much larger service specification from day one.

Benefits of data centre colocation

There are several reasons to consider using colocation services for your business. Here are some of the advantages of colocation for data management.


Colocation centres provide businesses with an affordable solution for their data management needs. With a colocation facility, you can scale up your hosted environment as your business grows.

Sharing space and infrastructure with other companies helps save on operational costs. This makes colocation a highly affordable solution.

Furthermore, companies can enjoy modern data centre infrastructure, cooling, experienced staff, and security.


Companies that choose to manage their own data have to set up server rooms. They also need to find trained staff to manage their hardware. A colocation service offers a more efficient way of storing and managing data.

Colocation centres offer efficient solutions to meet energy and cooling requirements. And on the whole, energy consumption is lower, thanks to improved power efficacy.

Colocation facilities are engineered for high uptime. If your business relies on online traffic, then outages are simply unacceptable. With colocation services, you can be sure your systems are operating in a stable environment.


Colocation facilities are flexible and provide a range of carrier connectivity options. They can also offer blended transit services, spreading bandwidth between several carriers. This ensures 100% network availability.

With colocation services, you can increase space, equipment, and power as you need to. In-house server rooms may be difficult to scale once your business starts growing. You don’t have to worry about this with colocation centres.


Colocation lets companies make use of resources that would otherwise be too expensive. One advantage of using colocation centres for data storage is security.

Colocation centres have several layers of security and threat detection to protect infrastructure. These facilities are also monitored at all times using CCTV cameras. And personnel are on active patrol 24/7.


Another important advantage of colocation services is the scalability that they provide. With a colocation setup, expanding is quick and seamless. The same can’t be said for in-house setups and server rooms.

Colocation makes it easier to grow long-term. This is thanks to better control over fixed-costs and IT budgets.


Colocation offers global and secure connectivity. These facilities provide fast networking solutions and stable connectivity at an affordable cost. Traffic flow on the network is monitored to ensure minimal downtime.

Fast internet connectivity is not always possible at an office location. And employing personnel to manage specialist equipment can be costly.

Sustainable infrastructure

Colocation provides organisations with a fully auditable system. They also have full control over their IT infrastructure. This is why colocation has an advantage over other data solutions such as cloud storage.

Cloud storage can be very expensive. It’s often more affordable for companies to store data on their own servers.

Moreover, data centres are constantly researching and making use of green technologies. This allows companies to reduce their environmental impact.

Colocation vs in-house data facilities

What is in-house data storage? It’s when a company stores servers and networking hardware on their premises. Some companies prefer this antiquated method of data storage.

Why? Because it gives you full control over your equipment, and you can tweak and change your setup when you want.

There’s one problem – maintaining your own hardware can be complicated and expensive. Colocation centres provide a simple, turnkey solution that comes at an affordable cost.

Also, companies don’t need to worry about the cost of power, cooling, and security. Colocation facilities also increase uptime by offering stable connectivity and redundant power solutions.

Improve your data management with colocation services

A colocation centre provides organisations with scalable solutions for their data management needs.

Colocation allows companies to lease space for their IT infrastructure. This includes power, cooling, connectivity, and security. Many tenants lease space in the same facility. This makes colocation more affordable than in-house data storage.

Why you’ll thank yourself for using a third party provider for data management

The total global volume of data is expected to reach 175 zettabytes within the next five years.

With the rise of SaaS and the Internet of Things (IoT), can companies continue to host their own data in-house? Or should they look to a third-party provider to manage their information?

This article examines third party data centres as the ideal solution to hosting critical business data.

We explain what a third party data management service is and how it differs from on-site hosting. We also outline the benefits of data centres and how colocation is the perfect choice to store your data safely.

Read on to discover the best way to manage your business data through a third-party provider.

Why the need for data management?

Data continues to play a critical role in business, from storing customer records to analysing big data through AI.

Yet all this data needs to be stored somewhere. It must remain safe, be accessible at all times, and comply with all necessary regulations.

Downtime in a world where the workplace never sleeps is unacceptable.

Databases, Software-as-a-Service (SaaS), web sites—they all require uninterrupted data flow. Servers control this movement and offer authorised connections to read and update information. Misconfiguration or faulty hardware can decimate a business overnight if no one is there to help fix it.

It’s essential to not only have a system to manage business data, but also to ensure it remains available at all times.

Types of data storage

There are 3 recognised types of data storage solutions:

  • On-site or on-premises
  • Colocation services
  • Cloud storage

On-site or on-premises

On-site data gets stored inside of a local or wide area network within the company’s own premises. For small to medium-sized businesses, that means using servers located in a dedicated data room or closet.

Full responsibility for this hardware lies with the office or IT manager.

That includes organising the installation, security, and maintenance of each piece of hardware. Any outdated equipment must be replaced and managers are ultimately liable for any downtime.

Colocation services

Companies that need bigger or better data management solutions use colocation.

Colocation services store data on company-owned equipment, but then house this equipment off-site, in a purpose-built data centre facility. Instead of having to physically house and service their own servers, they use a data centre to host their hardware.

Data centre operators like Netwise offer a dedicated solution to store your company data.

Businesses can either purchase their own servers or let us order, configure, and install them on your behalf. They’re placed in server racks, which can be divided into segregated cabinets, or even provided on a per unit basis.

Data centres are fully secured, both digitally and physically. They’re also monitored for intrusions such as hacking attempts and DDoS attacks.

Cloud storage

Cloud storage lets you save information to an off-site location, held on large distributed systems owned an operated by a cloud service provider.

Cloud providers host, manage, secure, and maintain all the necessary hardware. They’re also responsible for the infrastructure that lets you access your data.

A cloud storage system often uses multiple clusters of servers to host data. They’re termed data buckets and companies use them to hold multiple digital objects like videos or back-up files.

What is a data management third party provider?

A third party provider is an external company that’s responsible for hosting your data.

Unlike on-site storage, they help to maintain and control your servers for you. Our world-class London data centres enable our clients to colocate their own servers and utilise our high-uptime utilities.

But what are the main differences between a third-party provider and managing data on your own premises?

On-site vs online data centres

Until quite recently, most businesses traditionally stored data in-house, on the servers they keep in their offices.

That required the purchase and installation of cabling, switches, a network cabinet, and the servers themselves. Not to mention licencing the right software.

For many years, Microsoft SBS enabled Windows PCs to store and share files over a company’s network. Back-ups were saved to costly tape drives and placed in a fire-proof safe.

So why did Microsoft Small Business Server come to its end of life in January 2020?

Online data management

With the rise of broadband and fibre internet, companies abandoned on-site methods in favour of online solutions.

Modern internet infrastructure enables the sharing of terabytes of data around the world, all at the speed of light. That global network now enables businesses to store and access large volumes of information via third-party data centres.

Low latency combined with robust security ensures a better service than hosting on-site. But the benefits don’t stop there.

Benefits of a third party data management provider

Unlike your business’s premises, data centres are designed to do one thing: host your critical data.

A data centre provider like Netwise can manage your company’s data by offering:

  • Multiple reliable power sources
  • Resilient, high-performance connectivity
  • DDoS mitigation services
  • Multi-unit to full rack colocation services
  • Dedicated and custom hosting
  • Access to software licencing

Data centres come equipped with UPS hardware to ensure systems stay up when the power goes down.

Security software continually monitors for intrusion attempts and attacks. And they can provide custom servers to match your exact requirements.

Colocation vs public cloud

What’s the difference between a cloud host and a colocation data centre?

The main issue is where your private data gets stored.

A public cloud host saves your sensitive information on servers all around the world. There are often no geographic constraints which can cause problems when protecting data. It’s also more difficult to set-up an environment that’s dedicated to a legacy system on the cloud.

With a colocation provider, everything’s kept on your own servers.

You know exactly where your hardware is at all times, which makes life easier for GDPR compliance etc. You also manage who accesses it and what’s stored there.

If you want full control over your data but don’t want the limitations of hosting it yourself, always choose the colocation option.

The importance of sustainable data centres in London

The internet is used by more than 4 billion people worldwide.

The UK makes up for 60.3 million of these internet users, Great Britain bringing in 46.6 million as of 2016. That’s 92.6 per cent of our nation’s population; and growing.

We in London spend large chunks of our days on the internet, amplified further at the moment by the current COVID-19 restrictions. Whether it’s viewing our feeds on social media, sending work emails, video conference calls, uploading files, sending messages, downloading information, or simply surfing the web, data centres in London are working rigorously to transfer this information from one sector to the next.

Simply put, it’s fair to say that the majority rely extremely heavily on the internet.

We spend a lot of our lives online, and yet the environmental impact caused by our heavy use of the internet is commonly overlooked.

As we increasingly become more digitalised, the internet continues to play a key role in our lives. As such, there comes a time in which we must address the effect the internet has on the environment. There’s no doubt the internet requires a massive amount of energy to operate, so how can we remedy the effects of our carbon footprint? Where do we begin to address these effects?

It all starts at the data centre.

The internet in tangible form – data centres

It’s easy to fall short in understanding just how the internet requires so much energy due to its “invisible” nature. Nevertheless, there are four main areas that drive the digital world; devices, networks, manufacturing, and data centres. The latter being of tangible form and largely contributing to the egregious energy consumption the internet partakes in. 

Think of a data centre as you would a modern-day factory. They are physical facilities that function as large scale communication hubs and centralised computing facilities. These buildings can essentially be viewed as a collection of specialised computers, known as servers. These computers house a wide variety of things, including databases, websites, communication platforms, AI systems, and much more.

In short, data centres are the internet, materialized. They are the closest thing to the internet in physical form and they are one of two main components of the internet that contribute to having a very notable impact on the environment.

Why do data centres consume so much energy?

Think about data centres as you would your own personal computer. Your computer generates heat when in use. This heat is that energy. You know you’re generating a lot of heat when you hear the fans in your computer start to hum. Now imagine this but on a much, much larger scale. Millions of these specialised computers, known as servers, which are often many times more powerful (and power hungry) than your average home computer.

As a result, more than 4 billion individuals indirectly contribute to the IT sector’s energy consumption, which equates to 10 per cent of all energy consumption worldwide. This number is on continuously on the rise as we become more and more digital. It’s predicted that this number could increase to as much as 33 per cent by 2025.

Because of your indirect contribution to this consumption through use of your various digital services and platforms, a fair part of your carbon footprint comes from the operation of data centres. As an end-user, you have no input regarding what kind of energy your indirect data centre operators are purchasing and using. 

So, what is there to do?

The future of internet sustainability 

Thankfully, we’ve too found ourselves in a collective cultural transition into renewable energy and the IT sector has followed suit – in fact, it’s lead the way in pervasive use of renewables. As society has shifted to having more concern for our impact on the environment, corporations have also looked to shift towards sustainable energy.

Data centre operators have been racing towards a completely renewable internet for quite some time. Not only is this change great for the environment, it’s also advantageous from a financial standpoint; sustainable energy is consistent in its nature, and therefore holds great value for companies and investors.

‘Going green’ has become standard in terms of what business are looking for when choosing a data centre partner. Because of this, modern internet companies are now actively pursuing green, more sustainable providers to partner with on a long-term basis. Finding a truly sustainable data centre operator in the centre of a city like London can be tough, but they are

Do you need a colocation centre to store your business data?

Every year, businesses collectively spend trillions of dollars on IT products and services worldwide. In fact, the global forecast for the sector reached $3.46 trillion for this year, which is quite a staggering figure.

All over the world, businesses have to make the right decisions in IT management every year. So how can you make the correct cost-effective moves that will truly protect your business?

Most businesses have basic IT needs such as affordable server space and server hardware.

If you’re looking for more in-depth options to manage your business data, here’s how and why a colocation centre might be the best solution for your organisation.

What are colocation centres?

Colocation centres, or “co-lo” data centres, contain enterprise data servers at a remote location away from your own business premises. This is a purpose-built facility designed specifically to house business data systems and infrastructure.

Your own IT technicians are then able to visit the site for any maintenance or updates, or use the facility operators in-house technical team to assist you remotely.

The transfer process

Your service provider may supply you with the physical server hardware, or if you already have hardware in place, you can choose from a variety of service packages for the space you need.

To find how much infrastructure you require, you will need to consider a variety of factors, including the power requirements for each of your servers. Your provider can help you understand what specification service you’d need to support your systems.

During this process, you should evaluate how much space and resources you need, both now and in the future. You may also want to take this opportunity to immediately upscale or downscale, since you’re now entering into the process of bolstering your technical capacity. 

Common issues in business data management

For many businesses, server space is a limited commodity on-premise. This is especially true for small businesses that typically have smaller operations.

IT resources simply grow in proportion to the scale of large businesses. No matter how much building capacity your business has now, more data in the future tends to mean more space will be required.

Physical space is just one of the issues that many businesses run into when growing their systems. Overall costs for data solutions can grossly overtax a business’s financial resources. 

Colocation centres are uniquely designed to hit both of these major pain points for business.

In general, a colocation data centre helps businesses centralise their data management and scale the space to their needs. This offers more flexibility, reliability, and predictability to help you achieve your operational priorities. 

Maintenance and flexibility

Colocation data centres often function like managed IT services. Because of this, data service providers can conduct regular maintenance on your behalf. This can be a big cost saver, and reduces stress on internal technical resources that can spend more time on core business functions. This also reduces the in-house personnel required to perform maintenance.

However, you also have the option to manage your own hardware maintenance through your internal IT department if you choose. 


Choosing to make use of an outsourced colocation service provider will always offer you increased security and reliability over going in-house.

Colocation server hosting can be an alternative to cloud storage. Many organisations that made the leap to cloud services when they began taking hold a few years ago are now moving back to physical colocation services. This is because they offer greater value for money, decentralise the control of data from the large US cloud service operators, and allow for far easier compliance when it comes to data domicile and security.

Being able to point to your own server hardware, and make physical changes to it, has major operational advantages.

Predictable expenses 

Operating costs for data management can become expensive over time. When businesses choose to manage their own IT needs the expenses typically include:

  • Electricity to power servers
  • Maintenance and equipment
  • Security
  • Data recovery
  • General overhead costs

Fortunately, you can reduce these expenses when you choose a colocation data centre. One of the best advantages to outsourcing your IT management is that providers offer services at predictable, contracted rates. 

Breaking down monthly costs

For example, a proper colocation plan will show you exactly how much space your services will occupy. These spaces are typically measured in “rack units,” also labelled as a “U.” Units will be the first expense in your data management plan, usually coming with a monthly rate for the space.

There are also predictable monthly rates for power flowing to your servers and your network bandwidth. 

Some providers may also offer additional consulting or hardware resources that may be included in your service free of charge. However, some may come at additional cost. 

At any rate, the necessary expenses for colocation data centres are largely predictable and simplified. This allows you to anticipate the costs by tailoring your service to the specific needs of your business.

Unlike traditional IT management, you don’t have to worry about surprise costs. You simply pay for exactly what you need.

Find better business data solutions

The best advantage to colocation data centres is the fact that you can customize your service to the needs of your business. 

Whatever your data management goals are, we’re here to help you achieve them with colocation solutions.
