Q & A

What is the fundamental concept of cloud computing as described in the 2005 ACM Computing article?

The fundamental concept of cloud computing is defined as a means to enable on-demand network access to a scalable pool of computing resources, allowing for the use of various services and applications by a broad range of users from researchers to students and the general public.

What does the script suggest about the importance of conditions over hardware in cloud computing?

The script suggests that cloud computing focuses more on conditions (such as service level agreements) rather than hardware specifications, emphasizing the flexibility and scalability of services based on user needs.

What are the various deployment models of cloud computing mentioned in the script?

The script refers to the NIST model for cloud computing, which includes various deployment models such as public, private, hybrid, and community clouds, but does not explicitly list them in the provided transcript.

How does the script relate cloud services to service providers and consumers in terms of benefits?

The script indicates that the use of cloud services can potentially reduce the need for consumers to manage their own infrastructure, suggesting a reduction in costs and complexity, with service providers handling the service management.

What is the significance of resource pooling in cloud computing as discussed in the script?

Resource pooling in cloud computing allows for the efficient use of resources, potentially reducing costs by up to 90%, as it enables the sharing of resources among multiple users instead of each user having to own and maintain their resources.

How does the script compare the economics of owning versus renting resources in cloud computing?

The script uses the analogy of owning a car versus renting one to explain the economic model in cloud computing, where owning resources (like a car) might be unnecessary if they are not used frequently, making renting (or using cloud services) a more cost-effective option.

What are the challenges related to resource management in cloud computing as outlined in the script?

The script outlines challenges such as managing overloading and the need for efficient resource management to avoid unnecessary costs, as well as the importance of understanding the economic models behind resource usage.

What is the role of data management in cloud computing according to the script?

Data management in cloud computing is crucial as it involves how data is stored, managed, and serviced in the cloud, with considerations for scalability, reliability, and the potential for data loss.

How does the script address the issue of security in cloud computing?

The script addresses security by discussing the importance of access control, the need for robust security protocols, and the challenges of ensuring data integrity and confidentiality in distributed environments.

What are the script's views on open-source cloud and its various installation types?

The script suggests an interest in exploring open-source cloud solutions and their various installation types, indicating a desire to understand how these solutions can be implemented effectively.

What future aspects of cloud computing does the script express interest in exploring?

The script expresses interest in exploring the latest trends in cloud computing, including research at the postgraduate level, various projects, and different technologies, indicating a forward-looking approach to the field.
