Cloud Computing Fundamentals

An Internet connection is necessary for cloud computing interaction because cloud computing relies on remote servers to store, manage, and process data. Without an Internet connection, users would not be able to access these remote servers and utilize cloud services. Cloud computing is based on the concept of delivering computing resources over the internet, so a stable and reliable internet connection is essential for interacting with cloud services.

Google Docs is a type of cloud computing because it allows users to store and access their documents online. With Google Docs, users can create, edit, and collaborate on documents, spreadsheets, and presentations in real-time, all through a web browser. The files are stored on Google's servers, rather than on the user's local device, making it a cloud-based service. This allows for easy access to documents from any device with an internet connection, and also enables seamless collaboration and sharing with others.

Cloud computing is replacing all of the above options. Cloud computing allows organizations to store and access data on remote servers instead of relying on corporate data centers. It also eliminates the need for expensive personal computer hardware as users can access applications and data through the internet on any device. Additionally, cloud computing eliminates the need for expensive software upgrades as updates and maintenance are handled by the cloud service provider. Therefore, all of the mentioned options are being replaced by cloud computing.

The term "Cloud" in cloud computing represents the Internet. Cloud computing refers to the practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than using a local server or personal computer. The term "Cloud" is used metaphorically to represent the vastness and ubiquity of the Internet, where data and services can be accessed from anywhere and at any time.

Cloud computing has gained popularity in recent years, but one of the main concerns associated with it is security. As data is stored and accessed remotely, there is a fear of unauthorized access, data breaches, and loss of control over sensitive information. This concern arises due to the reliance on third-party service providers and the potential vulnerabilities in their systems. Organizations worry about the confidentiality, integrity, and availability of their data, making security concerns the number one concern about cloud computing.

The correct answer is that maintenance cost will be lower with cloud computing. This is because cloud computing eliminates the need for organizations to invest in and maintain their own physical infrastructure, such as servers and data centers. Instead, they can rely on the cloud service provider to handle these tasks, reducing the cost and effort required for maintenance. Additionally, cloud computing allows for scalability and flexibility, enabling organizations to easily adjust their computing resources as needed, further reducing maintenance costs.

Grid computing refers to a network of computers that share resources, whether it is a local network or distributed across the Internet. This concept allows multiple computers to work together as a single system, sharing processing power, storage, and other resources. By utilizing this network, tasks can be divided and executed simultaneously, increasing efficiency and performance. This approach is commonly used in scientific research, data analysis, and other computationally intensive applications.

Both statement A and B are correct. Elastic capacity refers to the ability of a system to quickly and easily scale up or down based on demand. Statement A states that elastic capacity can grow rapidly with the business, which means that the system can easily accommodate increased demand without causing lost revenue. Statement B states that elastic capacity can rapidly shrink with the business, meaning that the system can efficiently scale down when there is decreased demand, thus avoiding wasted expense. Therefore, both statements highlight the benefits of elastic capacity in terms of avoiding financial losses.

Amazon S3 is a cloud-based storage service provided by Amazon Web Services (AWS). It allows users to store and retrieve large amounts of data from anywhere on the web. It is commonly used for online backup and archiving purposes, as it provides a highly scalable and reliable storage solution. Therefore, the correct answer is "Both the above" as Amazon S3 serves as both an online backup and archiving service.

Cloud computing offers various benefits, such as location independence and not requiring user software installation. These benefits enable users to access their data and applications from anywhere and eliminate the need for software installation on individual devices. However, the exception mentioned in the question is that cloud computing is not customizable for individual customers. This means that the services and applications provided by cloud computing are not tailored to meet the specific needs and preferences of each customer.
