The conversation around cloud computing has shifted over the past few years. It used to be about whether you should move to the cloud. Now it is more often about when and how. But that does not mean it is the right answer for every business, and I think it is worth being honest about that from the outset.
We have helped dozens of organisations migrate to cloud platforms — mostly Azure — and we have also advised some clients to stay exactly where they are. The right answer depends on your circumstances, not on what a vendor’s marketing department wants you to believe.
The Genuine Benefits
Let me start with what cloud hosting does well, because the advantages are real and significant for most businesses.
Capital Expenditure Becomes Operational Expenditure
This is the one that resonates most with finance directors. Traditional hosting requires upfront investment in hardware: servers, networking equipment, storage, and a physical space to put it all in. That hardware depreciates, needs replacing every few years, and sits idle during quiet periods.
With cloud services, you pay for what you use on a monthly basis. There is no large capital outlay, and the cost scales with your actual usage. For businesses that are growing or have unpredictable demand, this model is far more efficient.
Scalability That Actually Works
On-premises infrastructure forces you to guess your future capacity requirements. Guess too low and your application falls over during peak periods. Guess too high and you are paying for hardware that sits idle.
Cloud platforms let you scale up or down based on demand. During busy periods, you can add capacity in minutes. When things calm down, you scale back and stop paying for what you do not need. For businesses with seasonal fluctuations — retail, tourism, events — this is genuinely transformative.
Disaster Recovery Without the Second Data Centre
Proper disaster recovery used to require a duplicate set of infrastructure in a separate physical location. That was expensive enough that many small and mid-sized businesses simply did not bother, accepting the risk instead.
Cloud platforms provide geographic redundancy as a standard feature. Azure, for example, replicates your data across multiple data centres automatically. Setting up a proper disaster recovery plan on Azure costs a fraction of what a physical secondary site would, and it is far more reliable.
Enabling Remote and Flexible Working
This benefit became obvious to everyone during the pandemic, but it remains relevant. Cloud-hosted applications and data are accessible from anywhere with an internet connection. Your team in Dolgellau, your clients in London, and your remote developers can all access the same systems without VPN complexity or bandwidth constraints.
Automatic Updates and Patching
Managed cloud services handle operating system updates, security patches, and platform maintenance. That is not just convenient — it addresses a genuine security risk. Some of the most damaging breaches in recent years have exploited known vulnerabilities that simply were not patched in time.
The Costs You Need to Watch
Here is where I want to be straightforward, because cloud hosting is not automatically cheaper than the alternatives.
The Monthly Bill Can Creep Up
Cloud pricing is consumption-based, which means costs can increase without anyone making a deliberate decision to spend more. A developer spins up a test environment and forgets to shut it down. Someone selects a higher-performance tier during a load test and never scales back down. Data transfer charges accumulate quietly.
Every cloud migration should include:
- Cost alerts set at sensible thresholds
- Monthly reviews of actual spend against budget for at least the first year
- Governance policies around who can create and modify resources
- Auto-shutdown schedules for development and test environments
Data Transfer Costs
Moving data into a cloud platform is usually free. Moving data out is not. This catches people out, particularly businesses that need to transfer large volumes of data between cloud services and on-premises systems. Factor egress charges into your cost modelling from the beginning.
Skills and Training
Your existing IT team may need training to manage cloud infrastructure effectively. Azure and AWS are powerful platforms, but they are also complex. The cost of upskilling — or of hiring people with cloud experience — should be part of your migration budget.
When Cloud Is Not the Right Answer
There are legitimate situations where cloud migration does not make sense, or at least not yet:
-
Heavily customised legacy applications that depend on specific hardware or operating system configurations may cost more to refactor for the cloud than they save in hosting fees. Sometimes the pragmatic answer is to keep running them where they are until a replacement is planned.
-
Extremely latency-sensitive workloads where every millisecond matters may perform better on dedicated hardware physically close to their users. This is niche, but it is real.
-
Regulatory constraints in certain industries may require data to remain on infrastructure you physically control. This is becoming less common as cloud providers obtain more certifications, but check the specifics for your sector.
-
Very stable, predictable workloads that never need to scale may genuinely cost less on traditional infrastructure that has already been paid for. If your server is three years old, fully depreciated, and running without issues, the financial case for moving to the cloud is weaker than vendors would have you believe.
Getting the Migration Right
If you do decide to move, the approach matters as much as the destination. Here are the pitfalls we see most often:
Avoid the Lift and Shift Trap
Taking your existing servers and moving them directly into virtual machines in the cloud is the fastest migration path, but it rarely delivers the full benefits. You end up paying cloud prices for an on-premises architecture, missing out on managed services, auto-scaling, and the other advantages that justify the move.
A better approach is to assess each application individually. Some are candidates for a straightforward lift and shift. Others should be re-platformed to use managed services. A few might be better replaced entirely.
Migrate in Phases
Big-bang migrations are risky. Start with lower-risk workloads — development environments, internal tools, non-critical applications — to build confidence and expertise. Move production workloads once you understand the platform and have your operational processes in place.
Plan for Hybrid
Most organisations end up running a hybrid environment for some period, with some workloads in the cloud and others on-premises. Make sure your networking, security, and identity management support this from day one. Retrofitting hybrid connectivity after the migration has started is painful.
The Practical View
Cloud hosting is a mature, proven approach that delivers genuine advantages for most businesses. The cost model is more flexible, the resilience is better, and the operational burden is lower than managing your own infrastructure.
But it is not magic, and it is not free. The businesses that get the most value from cloud migration are the ones that go in with realistic expectations, a clear plan, and a willingness to invest in doing it properly.
