"Move everything to the cloud" was the default advice for years. Today, many organisations are taking a more nuanced view: some workloads thrive in the public cloud, others are cheaper and simpler in colocation or on-premises, and some belong right at the edge. The right answer is usually a deliberate mix.
Start with the workload, not the platform
For each important application, write down five things: how predictable its usage is, how sensitive its data is, how much latency matters, how much data it moves, and how critical it is to the business. These answers do most of the deciding for you.
| Option | Often a good fit for | Watch out for |
|---|---|---|
| Public cloud | Variable or fast-growing workloads, new applications, managed services, global reach | Egress and storage costs at scale, cost governance, skills |
| Colocation | Steady, predictable workloads; owned hardware; strong connectivity to carriers and clouds | Upfront hardware investment, contract terms, remote-hands costs |
| On-premises | Workloads tied to a site, legacy systems, strict physical control | Power, cooling and resilience of the building; staffing |
| Edge | Low-latency processing near devices, sites with unreliable WAN, local data rules | Physical security and remote management of many small sites |
Don't forget data residency
Where your data is stored and processed can be as important as cost. Sector regulators, privacy laws and customer contracts in India, the EU, the GCC and elsewhere may require specific locations or safeguards. Map these requirements before choosing platforms.
Model cost over three to five years
Compare total cost of ownership, not monthly list prices: hardware refresh, licences, power, connectivity, support, staff time and exit costs. Steady workloads often look different over five years than over five months.
Plan for hybrid from the start
Most organisations end up hybrid. Design identity, networking, monitoring, security and backup to work consistently across environments, so moving a workload later is a project — not a crisis.
