Multi-Cloud vs Single Cloud: Proven Guide to Avoid Cost Risk

Multi-cloud is usually chosen for resilience and rarely costed properly. This guide compares multi-cloud and single cloud honestly: what the two models actually mean, where the real cost difference sits and how large it tends to be, the three places multi-cloud genuinely saves money, a risk ledger showing what each model protects you from, whether the uptime argument survives arithmetic, a five-question scoring framework, how to make a single cloud position safe without a second platform, and a worked three-year cost model for a mid-sized UK platform.

Cloud Exit Strategy: Proven Guide to Avoid Lock-In Risk

Almost every organisation agrees a cloud exit strategy is sensible and almost none holds a tested one. This guide sets out where lock-in genuinely comes from, what the four realistic exit routes cost in money and elapsed time, how egress charges and the new switching rules actually work, which architecture decisions keep the door open cheaply, what exit rights belong in the contract, and how to rehearse the plan so it becomes a capability rather than a filing-cabinet artefact. The point is rarely to leave. It is to be credibly able to leave.

AI Model Exit Strategy: Proven Guide to Avoid Costly Risk

Model portability is an engineering property, not a legal one. This guide sets out where AI lock-in actually forms across five layers — the API surface, the prompt estate, embeddings, fine-tunes and the evaluation record — and what a switch really costs at each level of preparation. It covers the abstraction patterns that pay for themselves, why an evaluation harness is the instrument that makes a switch defensible, which assets transfer between models and which do not, the contract terms that keep the door open, and a 90-day runbook you can run without pausing delivery.
