What is Cloud Computing?
Cloud computing is a service, usually provided by a cloud platform provider that includes its own set of tools and technologies. These are based on remote servers that can be accessed self-service over the internet. The cloud platform provider manages the storage, servers and networks required, businesses simply pay to use these services as and when they need them.
What is Colocation?
Colocation is a strategic move in the age of digital transformation, allowing businesses to rent space for IT infrastructure in a data centre. Colocation is the way forward for businesses as it provides the physical location, cooling, power and security, so that you can move to a future-proof agile IT infrastructure and expand your global footprint. Colocation services also include the possibility of multiple and hybrid cloud infrastructure, with direct access to providers such as Google, Amazon Web Services, and Microsoft Azure.
Advantages of Cloud
Cloud computing has a lower entry cost for businesses looking to expand their IT resources beyond servers in their own office. The self-service model allows for flexibility to scale up or down compute resources used depending on the business needs. The accessibility of cloud is another key factor in the growth of cloud hosting, with 94% of enterprises already using a cloud service.
Disadvantages of Cloud
The use of public cloud services has its downsides for businesses. The volume of data can grow quickly into cloud, which can balloon costs and surface potential security and compliance issues with sensitive data. To scale effectively, businesses should not solely rely on cloud storage, as it can be an expensive alternative to hybrid infrastructure that includes both colocation and cloud. Overuse of cloud resources by different teams in a business can lead to sprawling shadow IT which can be difficult to manage and consolidate efficiently when looking to scale digital transformation.
Advantages of Colocation
Colocation is an ideal solution for businesses that require a mix of hybrid and multi cloud storage, as well as servers that store data locally for compliance reasons. Businesses that have outgrown on-premise equipment in their offices, often don’t have the capex to build their own data centre, which is why colocation works so well.

Disadvantages of Colocation
Colocation requires businesses to provide their own servers and storage within the colocation facility which could cost more than using public cloud services, but it results in a much more secure infrastructure. Businesses have complete ownership and control over their equipment in colocation - but they need to consider the location of colocation very carefully. If engineers need to do routine maintenance on servers, a colocation centre situated far away from your head of operations could be a problem, costing time and money.
Colocation vs. Cloud - differences between Colocation and Cloud
Colocation and cloud are not mutually exclusive for businesses. Many companies use both or a combination of one with other IT infrastructure solutions. The main difference between cloud and colocation is how data is managed and stored. In cloud, servers are owned by the cloud provider and data is managed virtually. In colocation, servers are not owned by the colocation facility, but instead by the business that is leasing the space.
Colocation vs. Cloud - similarities between Colocation and Cloud
Cloud and Colocation both offer cost savings to businesses (compared to owned on-premise data centres) with cloud providers offering shared public resources virtually. Colocation is shared space within a data centre, but the resources within racks and cages are not shared, they are dedicated to the business that owns them. Shared resources in a colocation facility include:
- Cooling systems and redundancies
- Power systems and redundancies
- Security systems
Which is best for you?
Colocation and cloud both offer businesses different ways to store and manage their data. Cloud, while popular, has drawbacks that mean businesses are looking for alternative ways to include secure cloud in their hybrid IT infrastructure. With colocation, business owned servers can house data securely and locally, as well as benefit from direct connection routes to cloud providers such as Google, Amazon Web Services and Microsoft Azure with Interxion Cloud Connect.
