"Should we move to the cloud?" comes up in almost every first meeting we have. The answer depends on your internet link, your budget and what your data rules allow, and for most organisations it is not all-or-nothing.
What each option involves
On-premise means your servers sit in your own building. You own the hardware and control it, and you also have to power it, cool it, secure it, back it up and replace it when it ages. Cloud means renting computing and applications from a provider and reaching them over the internet. There is no hardware to buy and you can add or drop capacity as you need it. In exchange you depend on your connection and pay a subscription every month.
Five things to check before you decide
1. Connectivity
In many African markets this is usually the deciding factor. A cloud system is only as reliable as the link to it. If an office runs on one unstable connection, moving everything to the cloud means staff sit idle every time that link drops. With two links and automatic failover, cloud becomes a much safer bet. With one weak link, keep the systems people need every hour on site.
2. How the cost falls
On-premise is a large purchase up front (capital) plus maintenance. Cloud is a monthly operating cost that rises and falls with use. Neither is cheaper by default; it depends on the workload and how many years you are planning for. Cloud tends to suit needs that are growing or change month to month. Owning the hardware can work out cheaper for steady, heavy workloads you expect to run for years.
3. Control of your data
Some organisations have contract or policy reasons to keep certain data in-country or under their direct control. Write down what those rules actually require before you decide. Often only part of the data is sensitive and the rest can move without any issue.
4. Resilience
Large cloud providers run redundancy and backup that would cost a lot to build yourself. Resilience also means being able to keep working while the connection to the cloud is down, so local backups and an offline fallback still matter.
5. Your own IT capacity
Running servers on-premise properly takes skills and time. Cloud moves much of that work to the provider (and to whoever manages your IT), so a small internal team can spend its time on the business instead of the server room.
Why we usually recommend hybrid
For most growing organisations here we recommend a hybrid setup. Email, collaboration tools such as Microsoft 365 and customer-facing apps go in the cloud, where staff can reach them from anywhere. Systems that are sensitive to delay, or that must keep running when the internet is down, stay on site with a backup copy in the cloud. Add a second internet link with failover, and one outage no longer stops the whole operation.
