Czym jest model wdrażania w chmurze publicznej?

Public cloud, also known as external cloud, is a form of cloud computing that involves a third party providing end customers with access to the computing resources they require, such as servers, applications, and storage space, through the Internet. The provider runs them from its own data centers; the AWS Cloud, for example, spans 39 geographic regions as of October 2026. Public cloud services are usually billed on a ‘pay-as-you-go’ basis.

Główne modele wdrażania chmury to chmura publiczna, chmura prywatna i chmura hybrydowa. Każdy model jest dostosowany do potrzeb i wymagań określonej grupy użytkowników. Chmura publiczna oferuje współdzielone zasoby w celu zwiększenia efektywności kosztowej, chmura prywatna zapewnia dedykowane zasoby w celu zwiększenia kontroli, a chmura hybrydowa łączy oba te rozwiązania w celu zapewnienia elastyczności. Idealny model dla Twojej organizacji zależy od konkretnych wymagań, takich jak bezpieczeństwo, budżet i pożądany poziom kontroli.

Public cloud differs from on-premises infrastructure by ownership, payment structure, flexibility, assistance, and openness. Above all, while public cloud resources are owned and run by the third-party CSP, on-premise resources are owned and run by the actual company. This results in variations in costs, scalability, and responsibilities.

In this multi-tenancy model, each customer’s data and applications remain isolated (Microsoft Azure). However, in public cloud environments, data is stored across multiple servers in data centers owned and managed by cloud service providers (CSPs), where users lack direct control over these servers and posiadać less control over the underlying infrastructure compared to on-premises solutions.

When considering modele wdrażania chmury, the public cloud is applicable for scenarios involving fluctuating demand, such as websites with variable traffic, development and testing setups, and offsite data storage.

Some of the leading public cloud solutions include AWS, Azure, and GCP. The AWS Cloud spans 39 geographic regions as of October 2026 (AWS). Public cloud services fall into three models:

• Infrastruktura jako usługa (IaaS): Virtual machines, storage, as well as networking.
• Platforma jako usługa (PaaS): Rozwiązania w chmurze do tworzenia i wdrażania aplikacji.
• oprogramowanie jako usługa (SaaS): Applications stored w the cloud (such as Salesforce, Dropbox, and others).
