Ce este un model de implementare a cloud-ului public?

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.

Principalul Modele de implementare cloud sunt cloud-ul public, cloud-ul privat și cloud-ul hibrid. Fiecare model este orientat către nevoile și cerințele unui anumit grup de utilizatori. Cloud-ul public oferă resurse partajate pentru eficiență în ceea ce privește costurile, cloud-ul privat oferă resurse dedicate pentru un control sporit, iar cloud-ul hibrid combină ambele pentru flexibilitate. Modelul ideal pentru organizația dvs. depinde de cerințe specifice, cum ar fi securitatea, bugetul și nivelul dorit de control.

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 să aibă less control over the underlying infrastructure compared to on-premises solutions.

When considering Modele de implementare cloud, 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:

• Infrastructură ca serviciu (IaaS): Virtual machines, storage, as well as networking.
• Platformă ca serviciu (PaaS): Soluții bazate pe cloud pentru dezvoltarea și implementarea aplicațiilor.
• Software ca serviciu (SaaS): Applications stored în the cloud (such as Salesforce, Dropbox, and others).
