Cloud adoption has reached near-universal status among larger organisations:\u00a094% of enterprises now use cloud services in some form<\/a>, and\u00a072% of all global workloads are now cloud-hosted<\/a>.\u00a0Smaller businesses\u00a0are\u00a0not far behind:\u00a0the Flexera 2026 State of the Cloud report found that SMB workloads running in the public cloud jumped from 55% to 63% in a single year<\/a>, a sign that cloud is no longer an enterprise-only conversation.\u00a0\u00a0<\/p>\n\n\n\n

And yet success rates\u00a0remain\u00a0stubbornly mixed. Independent analysis shows that while cloud can unlock significant business value,\u00a0many programmes leak value through missteps and inefficiencies<\/a>. The pattern is familiar: promised savings, rushed timelines, unplanned complexity, and then a cloud bill that keeps climbing for reasons nobody can quite explain.\u00a0UK-specific\u00a0research also suggests that most businesses found their move to the cloud more costly than envisaged<\/a>, with delays and hidden complexity common.\u00a0<\/p>\n\n\n\n

In our experience, cloud projects do not fail because the technology is difficult; they fail because the questions were too vague. If your goal is to “be in the cloud by Q4”, you are already over budget – you just have not seen the invoice yet. <\/p>\n\n\n\n

\n\n\n\n

Why rushed cloud moves backfire<\/strong> <\/h2>\n\n\n\n

Cloud migration projects tend to go wrong for mundane and unglamorous reasons such as unclear objectives, limited discovery, optimistic budgets, and a “lift and shift” mindset that treats the cloud as if it is just another data centre. <\/p>\n\n\n\n

Cost control is the pain that lingers longest\u00a0because\u00a0a big chunk\u00a0of the outlay\u00a0is wasted through over-provisioned resources, idle environments and forgotten services<\/a>.\u00a0Waste compounds quickly when teams simply recreate on-premises architectures in the cloud without\u00a0considering how to improve things.\u00a0You\u2019re\u00a0on the\u00a0cloud\u00a0but\u00a0nothing feels cheaper, faster,\u00a0or simpler.\u00a0<\/p>\n\n\n\n

Human factors make this worse. People keep using systems the old way while the organisation pays for a new platform; speed of adoption does not automatically lead to well-managed adoption. <\/p>\n\n\n\n

The cloud is not inherently expensive or risky unless migrations proceed without a structured framework linking technical decisions to business intent. If migration is treated as a series of isolated tasks rather than an end-to-end transformation, it becomes very difficult to control risk, cost and performance.<\/em> <\/p>\n\n\n\n

A practical cloud migration framework that works<\/strong> <\/h2>\n\n\n\n

A workable cloud migration framework links three phases: strategy, execution and post-migration optimisation, with feedback loops between them rather than a simple linear path.  <\/p>\n\n\n\n

Phase 1: Cloud Migration Strategy and Discovery.<\/strong>\u00a0<\/h3>\n\n\n\n

Define why you are moving, what success looks like, and which applications are actually suitable for migration.\u00a0This is where structured assessments, such as\u00a0Cardonet’s\u00a0formal\u00a0Cloud Readiness Service<\/a>, give you evidence rather than assumptions by reviewing application, integration, and operational requirements.\u00a0<\/p>\n\n\n\n

You can map applications to migration approaches using established patterns often described as the “6 Rs”: rehost, replatform, refactor, repurchase, retain, or retire.  <\/p>\n\n\n\n

Not every workload deserves the same amount of effort and forcing everything into a lift-and-shift model usually guarantees higher costs and limited benefit. A legacy reporting tool that nobody uses should be retired not retained. <\/p>\n\n\n\n

Migration priorities must be linked to business drivers, for example reducing data centre exposure, enabling remote work, supporting new digital services, or meeting regulatory requirements. If you can\u2019t explain how migrating a system will shift the dial, it should not be a priority. <\/p>\n\n\n\n

Phase 2: Cloud Migration<\/strong><\/strong> Detailed Planning and Design.<\/strong>\u00a0<\/h3>\n\n\n\n

Translate strategy into concrete architecture,\u00a0timelines\u00a0and responsibilities by defining landing zones, identity and access models, networking, security\u00a0controls\u00a0and backup strategies before workloads move, rather than treating these as follow-up tasks. Build a realistic migration roadmap that sequences workloads and plans for testing and rollback.\u00a0Identify\u00a0where you will use automation tools or Infrastructure as Code to\u00a0maintain\u00a0consistency and repeatability.\u00a0<\/p>\n\n\n\n

Phase 3: Cloud Migration<\/strong><\/strong> Execution.<\/strong>\u00a0<\/h3>\n\n\n\n

This is where well-planned frameworks prove their value because you are following a defined playbook rather than improvising under pressure. Phasing migration, starting with lower-risk or non-critical workloads,\u00a0lets you\u00a0test patterns, refine automation,\u00a0and build confidence before tackling complex or business-critical systems.\u00a0\u00a0<\/p>\n\n\n\n

You earn the right to move critical systems by showing that the approach works on less risky ones. <\/p>\n\n\n\n

Operational continuity must be a hard constraint. This means planning maintenance windows, fallback paths, data synchronisation mechanisms, and clear communication so business users know what to expect and how to raise issues during cutover.  <\/p>\n\n\n\n

It also means defining measurable success criteria for each wave of migration instead of treating “in the cloud” as the only goal that matters. <\/p>\n\n\n\n

Skills and ownership are equally important during execution. UK research into cloud migrations highlights skills shortages and unforeseen complexity as key reasons why projects overrun or underperform, especially where internal teams are expected to learn new platforms while maintaining existing services.  <\/p>\n\n\n\n

Clarifying responsibilities between internal IT, cloud providers and partners and ensuring that support processes reflect the new environment will help avoid gaps where incidents fall between teams and remain unresolved.  <\/p>\n\n\n\n

One practical rule: if everyone is responsible for a migrated application, nobody is. <\/p>\n\n\n\n

Post-migration optimisation: reclaiming value from the cloud<\/strong> <\/h2>\n\n\n\n

One of the most persistent myths about cloud migration is that the work ends once the last workload has moved. In reality, post-migration optimisation is where a significant share of the financial and operational value is either captured or lost, depending on how actively you manage the new environment. Migrations can deliver meaningful cost savings when well-executed, but poor configuration and limited governance can also lead to considerable wastage. <\/p>\n\n\n\n

Effective post-migration optimisation covers three main areas:  <\/p>\n\n\n\n
