Cloud Computing: Pros & Cons for Your Business Needs

4 June 2023

6 min Reading Time

Cloud computing is no longer a question of whether for most businesses, but of how. According to Gartner, global public cloud spending will surpass the $723 billion mark for the first time in 2025. At the same time, 60 per cent of IT decision-makers report that their cloud costs exceed original estimates. The cloud offers massive advantages – but also risks that often only become visible after migration. This article delivers an honest stocktake.

TL;DR

Global public cloud spending will reach $723 billion in 2025 (Gartner, October 2024).
Businesses save an average of 20-30 per cent on infrastructure costs after migration – but only with proper planning.
Data sovereignty remains the top concern for European CIOs: 78 per cent cite GDPR compliance as the biggest cloud challenge (KPMG Cloud Monitor 2024).
Cloud outages cost businesses an average of $9,000 per minute (Gartner estimate).
89 per cent of organisations use multi-cloud strategies to avoid vendor lock-in (Flexera State of the Cloud 2024).

What Cloud Computing Really Means in 2026

Cloud computing is not a single product. It is an operating model: IT resources such as compute power, storage and software are no longer run locally but provided by an external provider over the internet. The three fundamental models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).

For businesses, the question has shifted in recent years. It is no longer about whether the cloud makes sense, but about which workloads should run where. On-premises, private cloud, public cloud, hybrid cloud – the architecture decision has become more complex. Those who set up their multi-cloud strategy correctly avoid the biggest pitfalls.

The Advantages of Cloud Computing

Scalability and Flexibility

The greatest advantage of the cloud is its elasticity. Businesses can scale compute power and storage up or down within minutes. Seasonal peak loads, new projects or growing data volumes no longer require months of hardware procurement. The IT infrastructure adapts to demand, not the other way around.

For mid-sized companies, this means: entering new business areas is possible without massive upfront investment. A startup can work with the same cloud infrastructure as a corporation – it only pays for what it uses.

Cost Efficiency with Proper Planning

Cloud computing shifts IT costs from Capex (capital expenditure) to Opex (operating expenditure). Instead of buying servers, maintaining them and replacing them after five years, businesses pay a monthly fee. Hardware procurement, electricity, cooling and physical security are handled by the provider.

Actual savings vary. Studies show figures between 20 and 40 per cent reduction in total cost of ownership. The key is planning: those who migrate to the cloud without cost monitoring often end up paying more than before. AI workloads in particular are driving costs in 2026: GPU-based inference workloads can multiply the cloud bill several times over.

Access to Innovation

Cloud providers such as AWS, Azure and Google Cloud invest billions in AI services, machine learning platforms and data-driven tools. Businesses that use the cloud benefit from innovations they could never develop on their own. Whether AI-powered data analytics, serverless architectures or edge computing – the cloud is the gateway to technologies that would be virtually impossible to achieve on-premises.

Disaster Recovery and Business Continuity

Cloud providers operate redundant data centres across multiple regions. Data is mirrored automatically, backups run in the background. For businesses that cannot afford their own disaster recovery infrastructure, the cloud is often the only path to a robust contingency plan.

The Disadvantages of Cloud Computing

Cost Trap Without Governance

The pay-as-you-go flexibility of the cloud has a flipside: without clear cost controls, spending spirals out of control. Orphaned instances, over-provisioned resources and unused reserved capacity are the most common cost drivers. According to Flexera, an average of 32 per cent of cloud spending is wasted. Those familiar with the problem understand why AI agents are challenging the SaaS model.

Data Sovereignty and Compliance

For European businesses, GDPR compliance is a central challenge. Where does the data physically reside? Which jurisdiction applies? The US CLOUD Act permits American authorities to access data stored by US companies – regardless of the server location. Those processing sensitive data must carefully assess whether an EU data centre is sufficient or whether a sovereign cloud solution is required.

Provider Dependency (Vendor Lock-in)

Every cloud provider has its own APIs, services and data formats. The deeper a business is integrated into an ecosystem, the harder it becomes to switch. The VMware-Broadcom situation is a textbook example of what happens when a vendor unilaterally changes its terms: price increases of over 1,000 per cent, with no realistic short-term alternative.

Availability and Outage Risk

Cloud services are not infallible. AWS, Azure and Google Cloud have all experienced significant outages in recent years. When a provider goes down, every business that depends on it comes to a standstill. The average cost of a cloud outage is approximately $9,000 per minute according to Gartner. Multi-cloud architectures reduce this risk but increase complexity.

Security Risks

The cloud is not inherently less secure than on-premises. But the shared responsibility model is frequently misunderstood: the provider secures the infrastructure, the business secures its data and configurations. Misconfigured S3 buckets, exposed databases and overly broad IAM roles are the most common causes of cloud data breaches. Those not keeping NIS2 and the SaaS supply chain on their radar risk compliance violations.

The cloud does not solve problems. It relocates them. And anyone who fails to grasp that is trading a server farm for a cost explosion.

Cloud vs. On-Premises: When Each Makes Sense

Not every workload belongs in the cloud. Stable, predictable loads with consistent utilisation are often cheaper on-premises. Variable workloads, rapid growth and globally distributed teams benefit from the cloud. The reality in 2026 is hybrid: according to Flexera, 89 per cent of organisations use a multi-cloud approach, combined with on-premises infrastructure.

The decision depends on four factors: cost structure (Capex vs. Opex), regulation (GDPR, NIS2, industry-specific requirements), scaling needs and internal expertise. Those without qualified cloud engineers should start with managed services rather than a complex multi-cloud architecture.

Frequently Asked Questions

Is the cloud cheaper than running your own servers?

Not automatically. With variable loads and rapid growth, yes. With stable, high utilisation, on-premises servers can be more cost-effective in the long run. The deciding factor is the total cost of ownership including staff, maintenance and electricity.

How secure is data in the cloud?

Major cloud providers invest more in security than most businesses could on their own. The risk lies in configuration: misconfigurations on the customer side are the most common cause of data breaches. The shared responsibility model makes it clear: the provider secures the infrastructure, the business secures its applications and data.

What is the difference between public, private and hybrid cloud?

Public cloud (AWS, Azure, GCP) shares infrastructure among many customers. Private cloud is exclusive to a single organisation. Hybrid cloud combines both: sensitive workloads run privately, variable loads in the public cloud. Most organisations use a hybrid approach in 2026.

What does vendor lock-in mean?

Vendor lock-in occurs when a business is so deeply integrated into a cloud provider’s ecosystem that switching becomes economically or technically unfeasible. Proprietary APIs, data formats and services increase dependency. Multi-cloud strategies and open-source alternatives reduce this risk.

Do I need a fast internet connection for the cloud?

Yes. Cloud services depend on stable, fast internet connections. For latency-sensitive applications such as real-time analytics or video conferencing, bandwidth is critical. Edge computing can reduce latency by processing data closer to the user.
