Pilviinfrastruktuureja

Pilviinfrastruktuureja, or cloud infrastructure, refers to the hardware and software components that enable cloud computing services. These services are delivered over the internet and managed by third-party providers, allowing users to access computing resources on-demand. The primary components of cloud infrastructure include:

1. Servers: Physical or virtual machines that host applications and data.

2. Storage: Solutions for storing data, such as databases, file systems, and object storage.

3. Networking: Components that facilitate data transfer, including routers, switches, and load balancers.

4. Virtualization: Technology that allows multiple virtual environments to run on a single physical server.

5. Security: Measures to protect data and applications, including firewalls, encryption, and identity management.

Cloud infrastructure is typically categorized into three main service models:

1. Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, such as virtual machines, storage, and networking.

2. Platform as a Service (PaaS): Offers a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

3. Software as a Service (SaaS): Delivers software applications over the internet, on a subscription basis, eliminating the need for users to install and run applications on their own computers.

Cloud infrastructure is designed to be scalable, reliable, and cost-effective, making it an attractive option for businesses of all sizes. It enables organizations to focus on their core competencies while leveraging the expertise of cloud providers to manage infrastructure.
