Pilvandmeteenused

Pilvandmeteenused, or cloud services, refer to a range of computing resources delivered over the internet. Rather than maintaining local servers or personal devices, users access processing power, storage, and applications through third‑party data centers. The core model is pay‑as‑you‑go, which allows organizations of all sizes to scale their IT infrastructure without large upfront capital investments.

There are three primary cloud service models. Infrastructure as a Service (IaaS) provides virtualized hardware, enabling customers to run operating systems and custom software. Platform as a Service (PaaS) offers a ready‑made development environment, delivering runtime, middleware and development tools. Software as a Service (SaaS) delivers end‑user applications over the web, eliminating the need for software installation or management. Hybrid and multi‑cloud strategies combine these models to meet specific business requirements, such as data residency, redundancy or cost optimization.

Security and compliance remain top priorities for cloud adopters. Providers employ encryption, authentication, and access control to protect data in transit and at rest. Many also obtain industry certifications, such as ISO 27001, SOC 2 and GDPR compliance, to meet regulatory demands. Providers conduct regular audits, vulnerability assessments and incident response drills. Nevertheless, customers share responsibility for securing their own data, configurations and applications.

The benefits of pilvandmeteenused include rapid deployment, global accessibility, high availability, and elastic scaling. They are widely used for workloads such as web hosting, data analytics, artificial intelligence, and disaster recovery. As technology continues to mature, providers invest in edge computing, serverless architectures and advanced automation to enable more efficient and intelligent cloud environments.
