Pilvepakkujad, also known as cloud providers, are companies that offer cloud computing services. These services allow individuals and organizations to access and use computing resources, such as servers, storage, and software, over the internet without needing to own or manage the underlying physical infrastructure. Cloud computing is typically delivered through three main models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

IaaS providers offer virtualized computing resources, including virtual machines, storage, and networking. Users can rent these resources on demand and manage their own operating systems and applications. Examples of IaaS providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

PaaS providers offer a platform that allows developers to build, deploy, and manage applications without worrying about the underlying infrastructure. This model typically includes operating systems, middleware, and development tools. AWS, Azure, and GCP also offer PaaS solutions.

SaaS providers offer ready-to-use software applications that are accessed over the internet, typically on a subscription basis. Users do not need to install or manage the software; the provider handles all maintenance and updates. Examples of SaaS include email services like Gmail, customer relationship management (CRM) software like Salesforce, and productivity suites like Microsoft 365.

The advantages of using cloud providers include scalability, flexibility, cost-effectiveness, and reduced IT management overhead. Businesses can easily adjust their computing resources up or down based on demand, pay only for what they use, and focus more on their core business activities rather than IT infrastructure.
