We often hear from clients that they’re “on their cloud journey” or planning to “move everything to the cloud.” But is the path to the cloud really that straightforward? The reality is that not every application, workload, or service can — or should — be migrated. Adopting a cloud-first strategy too quickly, whether driven by executive enthusiasm or the appeal of frameworks like G-Cloud (which simplifies public sector cloud procurement), could introduce unnecessary complexity, unexpected costs, and performance challenges — ultimately slowing innovation rather than enabling it.
As strategic advisors, our role at WhiteSpider is to help organisations cut through the hype and make informed decisions about what belongs in the cloud, what should stay on-premises, and why. This means understanding the nuances of each option — public, private, hybrid, multi-cloud, and community cloud — and helping organisations design an approach that fits their unique goals, requirements, and application use cases. For instance, one application might perform best in the cloud, while another could be better suited to a SaaS model.
Across industries, organisations are increasingly, and often justifiably, turning to cloud computing to enhance agility and scalability while moving beyond the potential limitations of traditional on-premises systems. Government research shows that 99% of UK businesses with at least 10 employees handled digitised data in 2024, of which 35% stored and processed data on-premises, 19% used a public cloud provider, and 13% used a private cloud provider. These figures show how widespread cloud adoption has become, yet also highlight that a significant portion of businesses still rely on traditional or hybrid approaches to balance security, cost, and performance.
The question, then, isn’t whether to move to the cloud – it’s which type of cloud best supports your organisation’s strategy and use case of applications. As hybrid cloud computing specialists, we explore the different cloud options available and how each can help you so that you can make informed choices.
Public cloud services
Public cloud services offer businesses an affordable and practical way to access substantial computing power without requiring significant investment in physical infrastructure.
Leading providers continue to expand their ecosystems, offering an ever-growing range of services. With flexible, pay-as-you-go pricing and fast scalability, public cloud gives organisations the ability to scale as demand changes with minimal CapEx costs — all while IT support is managed by the provider.
As public cloud environments are built on infrastructure not owned by the end user, they’re typically deployed as Infrastructure as a Service (IaaS) or developed into Platform as a Service (PaaS), providing accessible and adaptable technology for rapid innovation.
Hosted private cloud solutions
For organisations where security, compliance, and control are top priorities, a hosted private cloud is often the preferred option.
Hosted private cloud delivers dedicated computing resources to a single business, providing greater reliability and customisation. With no shared infrastructure, organisations benefit from enhanced performance and easier compliance management — ideal for highly regulated sectors such as finance, government, and healthcare.
Developed on offsite, supplier-owned data centres, hosted private cloud services combine flexibility in infrastructure management with the added advantage of a secure, isolated environment for robust data and network protection.
Private data centre
A private data centre is an environment that an organisation owns, operates, and manages entirely, typically located on-premises or within a co-location facility. Unlike a hosted private cloud, where you rent a dedicated environment managed by a third party, a private data centre gives the organisation full control over every aspect of the infrastructure — from servers and storage to networking and security.
This model is particularly well-suited to workloads that are highly regulated or sensitive, such as defence operations or classified research, where strict compliance and data sovereignty are essential. It also makes sense for organisations with significant existing investments in hardware and facilities, or for scenarios where low latency or complete physical control over data is critical.
While this approach requires more internal resources and management, it provides maximum control, security, and flexibility for organisations with specialised needs.
Hybrid cloud services
A hybrid cloud approach brings together the best of all the previous options — blending public and private cloud environments to create a unified and flexible infrastructure. It means organisations can securely connect the two options and take advantage of each model’s unique strengths and features.
This model enables businesses to allocate workloads intelligently, running them in the most appropriate environment based on performance, cost, or security needs. Hybrid cloud also supports stronger business continuity, using private cloud for sensitive workloads and public cloud for reliable backup and disaster recovery.
As a cost-effective, scalable model, hybrid cloud allows gradual migration and flexibility to adapt as business needs evolve — making it a popular choice for organisations seeking balance between growth and current challenges.
Multi-cloud options
Sometimes, one cloud provider alone can’t meet every business requirement or application. Multi-cloud strategies enable organisations to use two or more cloud providers simultaneously — spreading workloads and resources across different platforms.
This approach helps avoid dependency on a single vendor while optimising workloads across platforms. It also offers broader global reach, competitive pricing, and access to specialised services, empowering businesses to tailor their cloud mix for performance, resilience, and efficiency.
Community cloud
Community cloud models are designed for multiple organisations with shared goals — such as security, compliance, or industry standards.
Unlike public cloud, which is open to all, or private cloud, which serves a single organisation, community cloud is built for a group with common requirements. This allows participants to share costs and resources while maintaining a secure and compliant environment.
One of the main advantages of community cloud is cost efficiency and customisation. By pooling resources, organisations gain access to secure, specialised cloud environments without the significant cost of a private cloud service. This can be especially beneficial for government and healthcare sectors where compliance with strict regulations is critical.
Community cloud fosters enhanced collaboration and trust through a dynamic platform. It makes it easier to exchange information and manage resources effectively.
It’s not ‘cloud-first’, it’s what type of cloud?
Ultimately, choosing the right cloud solution depends on your specific business and application needs. Public, private, data centre, hybrid, multi-cloud, or community cloud each offer different advantages depending on your security, scalability, compliance, and cost requirements.
