key term - Cloud Computing

Definition

Cloud computing is a model of computing that enables on-demand access to a shared pool of configurable computing resources, such as networks, servers, storage, applications, and services, over the internet. It allows users to access and utilize these resources without the need for local infrastructure or direct management by the user.

5 Must Know Facts For Your Next Test

1. Cloud computing allows users to access and utilize computing resources on-demand, without the need for local infrastructure or direct management.
2. The cloud computing model enables scalability, flexibility, and cost-efficiency by allowing users to dynamically allocate and release resources as needed.
3. Cloud computing services are typically delivered through a pay-as-you-go or subscription-based pricing model, allowing users to scale their usage and costs based on their requirements.
4. Cloud computing providers are responsible for the maintenance, security, and availability of the underlying infrastructure, allowing users to focus on their core business activities.
5. The widespread adoption of cloud computing has led to the emergence of various service models, including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

Review Questions

• Explain how cloud computing enables on-demand access to computing resources and the benefits it provides to users.
  • Cloud computing allows users to access a shared pool of computing resources, such as servers, storage, and software applications, over the internet. This on-demand access eliminates the need for local infrastructure and direct management, providing users with greater flexibility, scalability, and cost-efficiency. Users can dynamically allocate and release resources as needed, paying only for the resources they consume. Cloud computing service providers are responsible for maintaining the underlying infrastructure, ensuring its security and availability, allowing users to focus on their core business activities.
• Describe the different service models of cloud computing and how they cater to the diverse needs of users.
  • The cloud computing model has evolved to include various service models, each catering to different user needs. Software as a Service (SaaS) provides users with access to software applications hosted on the cloud, eliminating the need for local installation and maintenance. Platform as a Service (PaaS) offers a platform, including operating systems, programming languages, and tools, for users to develop, test, and deploy their own applications without managing the underlying infrastructure. Infrastructure as a Service (IaaS) provides users with on-demand access to fundamental computing resources, such as virtual machines, storage, and networking, allowing them to deploy and run their own applications and software. These service models offer users varying levels of control and responsibility over the underlying infrastructure, enabling them to choose the cloud computing solution that best fits their requirements.
