As a software development company, we’ve developed software that has been developed for cloud hosting and on-premises hosting. If you’re looking at developing a bespoke application or reviewing your current setup, making the right choice affects costs and how your software performs every day.
This post runs through the key factors to consider so you can make an informed decision on whether cloud vs. on-premises hosting is right for you.
What do we mean by cloud and on-premises hosting?
Cloud hosting means your software runs on servers owned and managed by a third-party provider, such as AWS, Microsoft Azure, or Google Cloud. You access it over the internet and pay for the resources you use, and the infrastructure is shared with other accounts through virtualisation.
On-premises hosting means your software runs on servers inside your own building or office, on your own network, or paying a third-party in a data centre. You own the hardware and are responsible for keeping it running, or you can lease/rent the hardware, but you’ll be responsible for managing it, including hardware upgrades.
There is also a middle option: a hosted or private cloud, where dedicated infrastructure is managed on your behalf. This is worth considering if neither standard option is a good fit for your business.
Costs
Cloud hosting generally has lower upfront costs. Rather than buying servers, you pay for the resources you use. But there are important caveats.
To get the full cost benefits of cloud hosting, software generally needs to be designed for the cloud from the start. Taking software that was built for on-premises infrastructure and moving it to the cloud will often cost more to run, not less. The savings associated with cloud hosting tend to come from architectural decisions made early in the build, not from simply switching where the software is hosted.
On-premises hosting requires upfront investment in hardware, plus ongoing costs for maintenance and eventual replacement. Over five to ten years, the total cost can be comparable to cloud hosting, particularly for larger organisations with stable, predictable needs.
Watch out for hidden costs on both sides. Cloud costs can grow quickly as your data volumes or user numbers increase. On-premises setups need IT resources and energy to keep them running effectively, and hardware will eventually need replacing.
Data control and security
On-premises hosting keeps your data on your own infrastructure. For businesses in regulated sectors with restrictions on where data can be stored, this may be a requirement rather than a preference.
Cloud providers invest heavily in giving you the tools to better secure your hosting, however, these often come at an additional cost and need to be carefully configured.
In general, cloud hosting is less secure than on-premises hosting, as the cloud is “public by default”. Unless you’re purchasing additional hardware level securing services, such as VLAN and VPN services, anyone can access your services via public internet.
Connectivity and resilience
Cloud-hosted software depends on a reliable internet connection. If your business operates in locations with variable connectivity, runs time-sensitive processes, or cannot afford downtime, you need to understand your provider’s uptime guarantees and what happens if the connection drops.
On-premises software runs on your local network and does not depend on an external connection. For manufacturing environments, remote sites, or anywhere operational continuity is critical, that independence can be a significant advantage.
Maintenance and IT resource
As mentioned already, with cloud hosting, the provider manages the infrastructure so that you do not need to worry about server maintenance, hardware failure, or data centre management.
On-premises systems need someone to look after them: patching, backups, and hardware maintenance. Some businesses handle this in-house; others work with a Managed Service Provider (MSP) to take on that responsibility.
Which should you choose?
Cloud hosting works well when you want lower upfront costs, minimal infrastructure overhead, and your software has been designed with cloud architecture in mind from the outset.
On-premises hosting makes more sense when data control is a regulatory requirement, when operational independence matters, or when your existing software was built for on-premises infrastructure and moving it to the cloud would increase rather than reduce your running costs.
