Choosing the infrastructure on which to host an application is a technical decision with direct business implications: costs, performance, security and the ability to scale with growth. Between cloud<\/strong> and dedicated server<\/strong>, there is no one-size-fits-all answer \u2013 only a decision that depends on the nature of the project, the available budget and the company\u2019s regulatory constraints. Here\u2019s how to make that choice on a sound basis.<\/p>\n\n\n\n

Understanding the two types of accommodation<\/strong><\/h2>\n\n\n\n

Before comparing costs or performance, we need to clarify exactly what these two options entail, as they are based on very different principles.<\/p>\n\n\n\n

The dedicated server: total control, fixed resources<\/strong><\/h3>\n\n\n\n

A dedicated server<\/strong> is a physical machine reserved exclusively for a single organisation, hosted either by a provider or on the organisation\u2019s own premises. The organisation has complete control over the configuration, but must plan its resource requirements in advance and manage maintenance, updates and scaling itself.<\/p>\n\n\n\n

The cloud: flexibility and on-demand resources<\/strong><\/h3>\n\n\n\n

Le cloud computing<\/strong><\/a> refers to access to IT services (computing, storage, databases) via the internet, billed on a pay-as-you-go basis. The main providers \u2013 AWS, Microsoft Azure and Google Cloud \u2013 offer resources that automatically scale to meet demand, without the need for any initial hardware investment. This elasticity makes it possible to absorb traffic spikes without having to permanently oversize the infrastructure.<\/p>\n\n\n\n

Compare actual costs over time<\/strong><\/h2>\n\n\n\n

The argument about price is often misrepresented: it is not the initial cost that matters, but the total cost over several years, taking into account the application\u2019s expected growth.<\/p>\n\n\n\n

The hidden cost of a dedicated server<\/strong><\/h3>\n\n\n\n

A dedicated server involves a predictable initial investment, but also hidden costs: hardware maintenance, replacement in the event of a breakdown, and the need to oversize the server to allow for future growth. If traffic remains stable, this budget predictability can be a real advantage.<\/p>\n\n\n\n

Pay-as-you-go cloud billing<\/strong><\/h3>\n\n\n\n

The cloud charges for resources actually used, meaning you avoid paying for unused capacity. On the other hand, a poorly configured infrastructure can lead to costs that spiral out of control if left unmonitored. A DevOps consultant<\/strong><\/a> implements monitoring systems that provide real-time alerts for any budget overruns, and can reduce cloud costs by 30 to 50 % through resource optimisation.<\/p>\n\n\n\n

Choose based on the application\u2019s traffic profile<\/strong><\/h2>\n\n\n\n

The right choice depends heavily on how the application\u2019s traffic changes over time. A project with stable traffic does not have the same requirements as a rapidly growing application.<\/p>\n\n\n\n

Stable and predictable traffic: dedicated servers remain a viable option<\/strong><\/h3>\n\n\n\n

For an internal application used by a constant number of users, with no major peaks in activity, a dedicated server can offer excellent value for money, with an infrastructure scaled once and for all.<\/p>\n\n\n\n

Whether traffic is stable or growing: the cloud comes out on top<\/strong><\/h3>\n\n\n\n

For an e-commerce site with seasonal peaks, a growing app or a service where usage is difficult to predict, the cloud automatically adjusts resources without the need for manual intervention, ensuring high availability without having to pay continuously for peak capacity that is rarely used.<\/p>\n\n\n\n

Taking data sovereignty into account<\/strong><\/h2>\n\n\n\n

Beyond cost and performance, the choice of hosting now raises an issue that is becoming increasingly important in the decision-making processes of European companies: where is the data physically stored, and under which jurisdiction?.<\/p>\n\n\n\n

The challenges of the US cloud for European businesses<\/strong><\/h3>\n\n\n\n

Storing data with a US cloud provider theoretically exposes organisations to the risk of access by the US authorities under the Cloud Act, regardless of where the servers are located. For organisations handling sensitive data (health, finance, personal data), this issue is becoming an increasingly important factor in their choice of provider.<\/p>\n\n\n\n

European cloud and sovereign hosting<\/strong><\/h3>\n\n\n\n

Providers such as OVHcloud, Scaleway and Hetzner offer a European alternative with the same flexibility as the US giants, whilst ensuring that data remains under European jurisdiction. This principle of sovereignty applies equally to application hosting and to the choice of business software, as demonstrated by the trend towards European sovereign ERPs<\/strong><\/a> as an alternative to US solutions.<\/p>\n\n\n\n

Combining the two approaches: the hybrid option<\/strong><\/h2>\n\n\n\n

The choice between the cloud and a dedicated server is not always a simple one. Many companies are adopting a hybrid architecture, which combines the advantages of both models according to the specific needs of each application component.<\/p>\n\n\n\n

Distinguishing between cloud service models<\/strong><\/h3>\n\n\n\n

Before choosing a cloud provider, it is worth understanding the difference between IaaS, PaaS and SaaS<\/strong><\/a> : IaaS provides raw infrastructure that you configure yourself, PaaS provides a platform ready for deploying code, and SaaS delivers a ready-to-use application directly. This choice determines the level of technical control retained by the organisation.<\/p>\n\n\n\n

Securing sensitive data on-premises<\/strong><\/h3>\n\n\n\n

A hybrid approach involves processing sensitive data on a dedicated or on-premises infrastructure, whilst utilising the cloud for components requiring greater processing power or flexibility. This architecture optimises costs, security and performance simultaneously, rather than relying on a single provider\u2019s standardised offering.<\/p>\n\n\n\n

Choosing the right accommodation with iterates<\/strong><\/h2>\n\n\n\n

iterates supports Brussels-based SMEs and start-ups in selecting and implementing their infrastructure: cloud deployment on AWS, Azure or Google Cloud, dedicated servers, or hybrid architectures. The hosting and application maintenance<\/strong><\/a> are guaranteed over the long term, with continuous monitoring of availability and costs.<\/p>\n\n\n\n
