Cloud, on-premises or hybrid? Making placement decisions deliberately

"Move everything to the cloud" and "keep everything in-house" are both simple answers to a question that rarely has a simple answer. For most established businesses, the right environment is a deliberate mix.

Why placement matters

Each workload has its own characteristics: how sensitive its data is, how variable its demand is, how closely it integrates with other systems, and what it costs to run in each model. Treating them all the same leads to either unnecessary cost or unnecessary constraint.

Factors to assess

• Performance and latency. Does the workload depend on proximity to users or equipment?
• Demand patterns. Steady workloads and highly variable ones suit different models.
• Data requirements. Contractual, regulatory or client expectations may shape where data lives.
• Integration. Tightly coupled systems are often best placed together.
• Resilience. What recovery objectives does the business need?
• Total cost. Include operations, licensing and skills, not just hosting.

Hybrid done well

A hybrid environment works when it is governed as one estate: shared identity, consistent security policy, unified monitoring and clear ownership. Without that, hybrid simply means two environments to manage.

Revisit regularly

Placement decisions are not permanent. As platforms, costs and business needs change, workloads should be reviewed and moved when there is a clear reason to do so.
