Choosing between colocation and the cloud is a common dilemma for many organisations. At a high level, it comes down to whether you want to run your workloads on infrastructure that you own and place in a secure data centre (either a private data centre or a third-party colocation facility) or operate them on infrastructure that is fully owned and managed by a cloud provider.
For the purposes of this blog, we group privately owned data centres and third-party colocation facilities under “colocation”, as both models offer similar characteristics when compared with public cloud.
Both colocation and cloud computing come with their own strengths and trade-offs. While the right choice is often influenced by factors such as cost, compliance needs, and operational control, with one of the most important considerations being the application use case. Modern, cloud-native applications are typically easy to run in cloud environments, but legacy applications can be far more expensive and complex to migrate—often where the hidden costs of “lift-and-shift” arise.
If your organisation manages business-critical IT systems, this blog outlines the key pros and cons of each option to help you assess which model best supports your current – and future – needs.
Colocation vs cloud: What do they mean?
To make an informed choice, you’ll need to understand the basics of colocation vs cloud so you can compare what each one offers and which is best for your needs.
What is colocation?
Colocation involves housing your servers, storage, and network equipment in a fully managed data centre. You’ll pay for the space, power, cooling systems and security required to keep your hardware operational. As you’ll still own and maintain the hardware, you’ll have full control of configurations and upgrades.
What is cloud computing?
Cloud computing involves moving your business functions and workloads onto infrastructure managed by a third-party provider or hosted in your own private cloud. Rather than buying and maintaining physical hardware, you have the flexibility to rent computing resources and only pay for the specific services you use. A cloud-based approach allows you to choose from several different deployment options tailored to your requirements. For example, private cloud gives businesses greater control and isolation, while public cloud offers more flexibility and scalability alongside lower upfront costs.
Colocation vs cloud: A full comparison
Both colocation and cloud computing allow you to run critical workloads without building your own data centre. But there are fundamental differences regarding cost, control, security, scalability and performance. Here is a direct comparison between colocation and cloud computing services:
| Feature | Colocation Computing | Cloud Computing |
| Governance & Control | You retain full ownership and responsibility for your hardware, operating systems, and configurations, while the data centre supplies the physical space, power, cooling, and security. | The cloud provider owns and maintains your critical infrastructure, leaving you to manage your applications, data, and configurations within their hosted platform. |
| Cost | Capital expenditure for hardware, along with ongoing costs for space, power and connectivity. Facility expenses are generally fixed, but you’ll take responsibility for all hardware upgrades and replacements. | Operational expenditure with flexibility and pay-as-you-go pricing. No upfront hardware costs, but expenses can increase with higher usage, greater cloud storage needs, and data transfer volumes. |
| Scalability | Scalable solutions for long-term stability, allowing you to add new hardware and secure extra space or power, often with lead times involved. | Scale instantly, giving you flexibility to support on-demand needs up or down in real time by modifying instance sizes or service levels. |
| Compliance & Security | You retain control of server hardening, network segmentation and tool selection, offering robust physical security. Ideal for strict or customised controls. | Extensive security features and recognised certifications. Compliance relies on proper configuration and shared-responsibility agreements and infrastructure. |
| Performance & Speed | Reliable speed and responsiveness thanks to direct control over hardware. You decide on network providers and interconnectors. | Depends on cloud provider architecture, geographic region and network routing. Convenient access to nearby managed services. |
What are the pros and cons of colocation and cloud hosting?
Understanding the major distinctions between colocation and cloud computing enables businesses to determine which workloads benefit from the hands-on control of colocation and which require the flexibility of cloud hosting. Here are some of the advantages and potential trade-offs of each option:
Colocation pros and cons
| Pros | Cons |
| ✔️ Full hardware and configuration control | ✖️ Colocation startup process can be overwhelming, though many providers guarantee a smooth transition |
| ✔️ “Smart hands” support when clients cannot physically access the data centre | ✖️ Reduced agility when it comes to scaling up or down |
| ✔️ Simplifies adherence to regulation and compliance standards | ✖️ Requires in-house expertise to manage, monitor and maintain equipment |
| ✔️ Dedicated resource and support, reliable performance | ✖️ Higher upfront costs for hardware and setup |
Cloud hosting pros and cons
| Pros | Cons |
| ✔️ Fast deployment of applications and resources | ✖️ Limited control over hardware and underlying infrastructure |
| ✔️ Ideal for dynamic, large-scale applications with variable workloads | ✖️ Security and compliance requirements can make shared resources unsuitable |
| ✔️ Lower upfront costs | ✖️ Costs can escalate – not just from ongoing consumption, but also from moving applications and data in and out of the cloud, which can be significantly more expensive than expected |
Colocation vs cloud: Which solution matches your business needs?
Both colocation and cloud computing offer significant benefits, but there’s no one-size-fits-all solution. The best choice depends on your workload, compliance requirements and how much control your business wants over its infrastructure. Here are some key considerations to bear in mind when choosing between the two.
1. Business size and growth status
New businesses and start-ups often benefit from the cloud’s flexibility and agility as well as the simplified cost structure. Meanwhile, larger organisations may require colocation for its core infrastructure reliability. However, colocation can also be suitable for smaller businesses thanks to the reliability and security it offers.
2. Compliance needs
Some industries and sectors, such as healthcare and finance, face strict data governance and compliance rules. This can make colocation necessary for handling specific workloads that require enhanced security and data protection.
3. Internal IT capabilities
Colocation demands in-house management of hardware and associated overheads. Meanwhile, cloud hosting removes hardware responsibilities but still requires oversight of applications and data.
4. Budget considerations
Companies focused on capital expenditure may prefer colocation, while those prioritising operational expenditure and scalability often lean towards cloud solutions.
