What is a cloud really, and why isn't it good for everything?
Over the past decade, cloud computing has become the almost default technology choice in the enterprise sector. The business rationale behind it is clear: the shift from capital expenditure (CAPEX) to operational expenditure (OPEX), the promise of scalability and flexibility is extremely attractive. Essentially, what the industry defines as cloud computing means that you don’t run your IT infrastructure – servers, storage, networks – in your own data centre, but rent it from a service provider over the internet. But technological empathy requires that you follow real business needs, not trends. The real question is which model will serve your business continuity with the highest level of reliability. The cloud can be public (shared resources), private (dedicated environment) or a hybrid of the two, which offers the most effective trade-off for most mature companies.
Cloud service models (IaaS, PaaS, SaaS)
Cloud services can be broken down into layers, and you need to understand where the line of responsibility lies between your company and the service provider for each model.
- Infrastructure as a Service (IaaS): essentially, the company rents the virtual hardware: computing capacity, storage and network. The management of the operating system and the software layers above it remains the responsibility of your company. This is the most flexible model, but the one that requires the most expertise.
- Platform as a Service (PaaS): the service provider provides the hardware as well as the running environment (e.g. operating system, database managers). Your company only needs to develop and manage the applications.
Software as a Service (SaaS): the highest level of abstraction, where you use a ready-made application accessible from a browser (e.g. CRM, office software suite). Here you have the least control, and in return the least maintenance.
When can the cloud become an obstacle?
Despite the flexibility of cloud-based operations, there are business and technology scenarios where the model has limitations and on-premise infrastructure provides a more stable, secure or even cost-effective solution.
- Bandwidth and latency: In industries where real-time data processing is critical (e.g. factory automation, financial transactions), latency caused by physical distance can be an unacceptable business risk.
- Data protection and compliance (GDPR) issues: in highly regulated sectors or when handling sensitive personal data, the geographical location of the cloud service provider’s data centre and its data management practices can pose serious compliance challenges.
- Risks of the “neighbour effect”: in a multi-tenant public cloud environment, extreme resource usage by another customer may negatively impact the performance of the customer’s systems, leading to unpredictable slowdowns.
Cloud vs On-Premise: The big infrastructure comparison
The choice of IT infrastructure is a strategic decision that directly affects the financial stability, operational efficiency and data security of your company. The choice is not just a technological one, it is a profound business one, where the flexibility of the cloud must be balanced against total control over your own hardware assets. Making the decision requires an understanding of the fundamental differences between the two models, as analysed in detail in the international press, showing both the advantages and disadvantages of cloud and on-premises models.
The key considerations are:
- Cost structure: monthly operating expenditure (OPEX) instead of capital expenditure (CAPEX)?
- Availability: who guarantees the continued operation of critical systems?
- Scalability: do you expect dynamically varying or stable, predictable loads?
- Control and security: where is your data physically located and who has access to it?
Calculation of the total cost of ownership (TCO)
The initial attraction of cloud services lies in the lack of capital expenditure (CAPEX), and the monthly fee (OPEX) model is predictable and easy to plan. However, in the longer term, over a 3-5 year time horizon, the cumulative monthly charges can exceed the cost of purchasing and operating a proprietary system. When calculating the total cost of ownership (TCO) of an on-premise infrastructure, hidden items such as power consumption, cooling, licence fees and professional maintenance must also be taken into account. With a vendor-independent support contract, these maintenance costs can be significantly optimised, making in-house hardware a financially competitive alternative in the long term.
Security and control: where is your data?
One of the main benefits of having your own server room is total control. Your company controls who can access the room, what security protocols apply and you know exactly where your company data is stored. In contrast, in the cloud, the responsibility for physical security is left to the service provider. In both models, a robust backup strategy is cardinal, but the on-premise environment gives you greater flexibility to design a customised solution. The condition of the hardware assets is essential to maintain the security level of the own infrastructure. Proactive IT hardware maintenance ensures that systems are not only reliable but also free of security vulnerabilities, thus enhancing business continuity.
The hidden costs of the cloud and the renaissance of physical hardware
The initial promise of the cloud – infinite flexibility and CAPEX-free start-up – is attractive to many businesses. However, during operations they are often faced with hidden costs that make monthly bills unpredictable. One of the most significant of these is the “cloud egress” charge, the cost of moving data out of the cloud. Imagine you need to restore a large database or move to another provider: the transaction fee could run into millions of forints, taking your financial planning by surprise.
Closely related to this problem is the vendor lock-in. When your systems are deeply integrated with a single cloud provider’s technology, switching is costly and even technically very difficult. Recognition of these challenges has given rise to the phenomenon of cloud repatriation: more and more large enterprises that have previously moved to the cloud are moving their critical systems back to their own on-premise data centres to regain control of costs, security and data assets.
Life after expiry of the manufacturer's support (EoL)
Hardware manufacturers often use a proven strategy: artificially encouraging expensive hardware replacement after the end of warranty and official support (End-of-Life, EoL). We approach this issue with technological empathy: we understand that your company does not want to replace a perfectly functional, proven system just because a date on the calendar has passed. Vendor-independent maintenance services, such as professional Hewlett Packard Enterprise (HPE) support, solve exactly that problem. We ensure continuous, reliable operation throughout the physical life of your hardware, saving you up to 40% compared to factory support fees.
Sustainability and hardware recycling
Extending the life of existing hardware is not only a financially responsible decision, but also an environmentally responsible one. The IT industry has a huge ecological footprint, so the principle of “repair, not discard” is strategic. Instead of scrapped devices ending up as electronic waste, we help make them valuable again. Professionally refurbished servers, storage and networking devices are ideal for building test and development environments, increasing redundancy or performing less critical tasks. This approach reduces environmental impact, optimises costs and contributes to a truly sustainable corporate IT infrastructure.
Decision framework: when should a company stay in its own server room?
The choice between your own server farm and the cloud is rarely black and white. While the flexibility of cloud solutions is attractive, there are business and technology scenarios where on-premises infrastructure is a strategic necessity. To make the right decision, a structured framework is needed that takes into account the unique operational characteristics of the company and the requirements of business continuity.
The first and most important step is to identify mission-critical workloads. This includes systems such as production management, central databases or applications that handle real-time transactions, where the smallest delay or service outage can cause serious business damage. In parallel, data security and regulatory requirements need to be assessed. Strict industry regulations (e.g. financial sector, healthcare) or GDPR data sovereignty principles often require that sensitive data remain within the physical corporate boundaries, under full control.
Running your own hardware also requires deep expertise and dedicated resources. The decision must be based on an honest assessment: does your internal IT team have the skills and capacity to guarantee the expected availability and security of your systems over the long term?
Checklist for infrastructure choices
The following questions will help you to find the right direction:
- What is the tolerable downtime? SLAs (Service Level Agreements) for business continuity often require a higher level of control than a standard cloud service.
- How often do resource needs change? Systems with stable, predictable loads can run more economically on their own optimised hardware.
- Is special hardware acceleration needed? Some tasks (e.g. AI model learning, high-performance computing) may require specialised GPUs or other hardware components that can be deployed in a more targeted and cost-effective way in an on-premise environment.
Operational challenges of the hybrid model
For most large enterprises, the future is not just the cloud or the server room, but an intelligent combination of the two. However, a well-designed hybrid strategy brings with it complexity: maintaining consistency, building secure network connections and managing the two platforms together requires considerable expertise. Network tools play a key role in ensuring smooth operations. We help you keep your headache at bay: by applying vendor-independent, international maintenance expertise, we ensure that your hybrid infrastructure provides a stable and reliable foundation for your business.

Frequently Asked Questions
Is the cloud cheaper in the long run than your own server?
The cost comparison is complex and the total cost of ownership (TCO) should be taken into account. The cloud converts high initial capital expenditure (CAPEX) into operating expenditure (OPEX), which gives flexibility. At the same time, for systems with stable, predictable workloads, a well-optimised, self-owned infrastructure can be more cost-effective in the long run. The decision always depends on the specific business needs, the nature of the load and growth plans.
What is a hybrid cloud and for whom is it recommended?
A hybrid cloud is a combination of private (on-premise) and public cloud infrastructures that work together in an integrated way. This model allows companies to keep sensitive data and mission-critical applications in their own secure data centre, while taking advantage of the scalability and flexibility of the public cloud for less critical or variable workloads, for example. It is particularly recommended for companies operating in a strict regulatory environment.
Is my data safer in the cloud than in my own office?
Leading cloud service providers are making physical and cybersecurity investments that would be out of reach for most companies. At the same time, security is based on a shared responsibility model: the service provider is responsible for protecting the infrastructure, but accessing data and configuring applications properly is your company’s responsibility. An improperly configured cloud environment can pose a serious security risk.
What is vendor-independent hardware maintenance?
Third-Party Maintenance (TPM) is a service that provides professional support and parts supply for your servers, storage and networking devices even after the manufacturer’s warranty has expired. This solution can significantly reduce your operating costs by up to 40% and extend the life of your existing hardware assets, avoiding costly and premature replacements.
What types of data should not be stored in the public cloud?
In general, it is not recommended to store data in the public cloud that is subject to strict industry or legal regulation, such as personal data classified as special category by the GDPR or information that is part of a national data estate. In addition, it is also preferable to keep your company’s most valuable intellectual property or trade secrets in a private or hybrid environment for maximum control and security.
How will the move to the cloud affect the IT team's tasks?
Moving to the cloud shifts the focus of the IT team away from routine hardware management tasks (e.g. installing servers, replacing components) towards higher value-added, strategic activities. They can spend their time optimising cloud architecture, managing costs (FinOps), automation and implementing security policies to more effectively support business objectives.
What happens to the data stored in the cloud if the service provider goes down?
Reputable cloud service providers have detailed service level agreements (SLAs) and contingency plans for such cases, which usually provide a grace period for data backup and migration. However, to minimise risk, a consciously structured backup and disaster recovery strategy, relying on multiple cloud platforms or hybrid solutions, is essential.
How to reduce the cost of running existing servers
There are several ways to optimise the cost of existing on-premise infrastructure. The most significant savings can be achieved by replacing vendor support contracts with a cost-effective, vendor-independent maintenance service. In addition, the virtualisation of systems, increased energy efficiency and the introduction of proactive monitoring will also help to reduce operational expenditure and losses due to unplanned downtime.
