A VPS (Virtual Private Server) is a dedicated portion of a physical server that functions as an independent server. Through virtualization, a single physical server is divided into multiple isolated environments, each with guaranteed resources (CPU, RAM, storage) and full root access.

KaralGreen VPS are hosted on physical nodes cooled by immersion in dielectric fluid. Unlike traditional VPS, where overheating causes thermal throttling and performance drops, our servers operate at constant temperatures of 30°–40°C, ensuring stable performance even under prolonged load.

The best VPS services for Italian users combine local infrastructure, direct support, and competitive costs. KaralGreen offers VPS on proprietary infrastructure in an Italian data center with specific advantages. In fact, with servers physically located in Italy, you get minimal latency and guaranteed GDPR compliance. Technical support is managed directly by our team, not by foreign call centers. The energy efficiency of immersion cooling (PUE 1.03) allows us to offer costs up to 50% lower while maintaining real performance: zero overselling, resources completely dedicated. Unlike international hyperscalers, we guarantee direct control over the infrastructure and Italian billing.

A VPS is reliable when resources are truly dedicated. If 10 virtual machines share 8 physical cores, expect slowdowns. Infrastructure efficiency determines the price: those paying high energy bills resort to overselling to remain competitive. KaralGreen reduces costs with immersion cooling (PUE 1.03) without cutting resources. Furthermore, support must be direct. An inexpensive VPS that leaves you waiting hours for assistance or support becomes the most expensive one.

A VPS shares the physical server with other environments, but the resources are dedicated and isolated. It costs less, scales easily, and works well for most projects: web applications, development environments, and medium-sized e-commerce. A dedicated server is entirely yours: zero sharing, maximum power, total control over the hardware. It costs more and is necessary when you cannot afford performance drops: critical databases that are always active, applications that saturate resources, or very specific hardware configurations. The rule is simple: start with a VPS. If in the future you find you need full power without sharing, switch to a dedicated server.

With KaralGreen, both solutions operate on immersion infrastructure, ensuring zero thermal throttling and consistent performance. The choice depends on your workload and budget: the VPS offers flexibility and low costs, while the dedicated server offers maximum power and control.

A dedicated server costs 3–5 times more than a VPS. It only makes sense to pay this difference if you constantly use all its resources. If your physical server is working at 30–40% capacity, you are wasting money. A VPS offers you exactly the resources you need at a proportional cost. You can scale when necessary, paying only for the increase. Most companies overestimate their needs: web applications, medium-sized databases, and staging environments work perfectly on a VPS. With KaralGreen, you save even more: immersion-cooled VPS cost up to 50% less than hyperscalers, offering superior performance to traditional VPS thanks to the absence of thermal throttling.

Public cloud seems cheap until you analyze the final bill. Between oversized instances, outbound traffic billed at a premium, snapshots, backups, and ancillary services, costs explode quickly. A VPS offers fixed and predictable costs: you pay a monthly fee for dedicated resources that are always available. If your load is relatively stable, a VPS costs you significantly less. With KaralGreen, you save even more: the efficiency of immersion cooling (PUE 1.03) allows us to offer VPS up to 50% cheaper than hyperscalers, without sacrificing performance.

A VPS is ideal for AI inference with pre-trained models, not for intensive training. If you need to deploy chatbots, classification APIs, recommendation engines, sentiment analysis, or NLP processing, a well-configured VPS is more than sufficient. It requires a powerful CPU, abundant RAM to load models into memory, and fast storage.

KaralGreen VPS offer CPUs with up to 500W TDP cooled by immersion: zero thermal throttling even under continuous 24/7 inference. Unlike traditional VPS that slow down after a few minutes under load, our nodes operate at 100% power constantly, ensuring predictable latency for your machine learning APIs.

For training complex models from scratch or GPU-intensive processing (video processing, large LLMs, image generation), dedicated hardware with GPUs is required. However, for the production deployment of most AI models, an immersion-cooled VPS offers the best price/performance ratio.
