With cloud computing, you can provision computing services, like server time and network storage, automatically. You won’t need to interact with the service provider. Cloud customers can access their cloud accounts through a web self-service portal to view their cloud services, monitor their usage, and provision and de-provision services.
Another essential cloud computing characteristic is broad network access. You can access cloud services over the network and on portable devices like mobile phones, tablets, laptops, and desktop computers. A public cloud uses the internet; a private cloud uses a local area network. Latency and bandwidth both play a major role in cloud computing and broad network access, as they affect the quality of service.
With resource pooling, multiple customers can share physical resources using a multi-tenant model. This model assigns and reassigns physical and virtual resources based on demand. Multi-tenancy allows customers to share the same applications or infrastructure while maintaining privacy and security. Though customers won't know the exact location of their resources, they may be able to specify the location at a higher level of abstraction, such as a country, state, or data center. Memory, processing, and bandwidth are among the resources that customers can pool.
4. Rapid Elasticity
Cloud services can be elastically provisioned and released, sometimes automatically, so customers can scale quickly based on demand. The capabilities available for provisioning are practically unlimited. Customers can engage with these capabilities at any time in any quantity. Customers can also scale cloud use, capacity, and cost without extra contracts or fees. With rapid elasticity, you won’t need to buy computer hardware. Instead, can use the cloud provider's cloud computing resources.
5. Measured Service
In cloud systems, a metering capability optimizes resource usage at a level of abstraction appropriate to the type of service. For example, you can use a measured service for storage, processing, bandwidth, and users. Payment is based on actual consumption by the customer via a pay-for-what-you-use model. Monitoring, controlling, and reporting resource use creates a transparent experience for both consumers and providers of the service.
On-Demand Self-Service. Self-service means the cloud user can acquire the service independently, without going through an IT department, call center, or other middleman. ...
Static environment is not an essential characteristics of cloud computing. Explanation: Cloud computing is a convenient configurable computational resources.
Cloud computing is defined as the use of hosted services, such as data storage, servers, databases, networking, and software over the internet. Since cloud computing began, the world has witnessed an explosion of cloud-based applications and services in IT, which continue to expand.
The NIST Cloud Computing Definition provides three possible cloud services categories (called service models): Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).
As shown in Figure 1, the NIST cloud computing reference architecture defines five major actors: cloud consumer, cloud provider, cloud carrier, cloud auditor and cloud broker. Each actor is an entity (a person or an organization) that participates in a transaction or process and/or performs tasks in cloud computing.
Clouds are typically sorted and identified by characteristics such as their height in the sky, texture, and the type of “weather” they do or do not produce.
Which Of The Following Is An Essential Concept Related To The Cloud. Answer. Option A is the Correct Answer. Abstraction in the context of cloud computing refers to the process of hiding complex underlying infrastructure details and presenting simplified and user-friendly interfaces to users and applications.

Here are the key features of cloud computing: On-demand self-service: Users can provision computing resources, such as servers and storage, as needed without having to interact with a cloud provider's staff.
7. ________ has many of the characteristics of what is now being called cloud computing. Explanation: The Internet offers abstraction, runs using the same set of protocols and standards, and uses the same applications and operating systems.
The cloud is a holistic ecosystem of components, not a point product or single vendor solution, and has basic, specific requirements to meet the needs of enterprise organizations. These requirements include scalability, adaptability, extensibility, and manageability.
