Unveiling the Answers to NPTEL Cloud Computing Assignment 8 2023
Cloud computing has revolutionized the way we store, process, and access data. It has allowed us to extend computing resources on-demand. NPTEL Cloud Computing Assignment 8 2023 is a comprehensive exercise that aims to evaluate a student’s understanding of cloud architecture and deployment models, cloud security, big data analytics, containerization, and more.
In this article, we will dive deep into NPTEL Cloud Computing Assignment 8 2023, providing you with answers to the questions asked in the exam, along with detailed explanations to enhance your understanding.
Cloud Computing Architecture and Deployment Models
Question 1: What are the four layers of a cloud computing architecture, and briefly explain each of them?
Answer: The four layers of a cloud computing architecture are:
1. Hardware Layer – This layer comprises servers, storage devices, network equipment, and other physical components required to run a cloud infrastructure.
2. Software Layer – It includes the operating system, virtualization software, and management applications that run on top of the hardware layer.
3. Platform Layer – This layer consists of development tools, application frameworks, and runtime environments that enable developers to build, deploy, and manage applications in the cloud.
4. Application Layer – It is where end-users can interact with the cloud application or service through web browsers or other devices.
Cloud Security
Question 2: List the five essential characteristics of cloud computing security.
Answer: The five essential characteristics of cloud computing security are:
1. Confidentiality – Ensuring that sensitive data remains confidential and protected from unauthorized access.
2. Integrity – Ensuring that the data is not tampered with or altered in any way during transmission or storage.
3. Availability – Ensuring that the desired resources are always available whenever needed, and the system can recover quickly from any disruptions.
4. Authentication – Ensuring that the identity of users is verified, and only authorized users can access the resources.
5. Authorization – Ensuring that users have the necessary privileges and permissions to access specific resources.
Big Data Analytics
Question 3: Explain the difference between structured and unstructured data, and provide an example of each.
Answer: Structured data is organized and formatted in a specific way, making it easy to analyze and work with. Examples of structured data can include data captured in relational databases, spreadsheets, and CSV files.
Unstructured data, on the other hand, lacks any defined structure, making it challenging to analyze. Examples of unstructured data can include social media feeds, emails, images, and video.
Containerization
Question 4: How does containerization differ from virtualization, and what are the advantages and disadvantages of containerization?
Answer: Containerization is a lightweight form of virtualization that allows applications to run in isolated environments without the need for a full-blown operating system. Containers share the host operating system kernel, which makes them faster and more efficient than virtual machines.
Advantages of containerization include faster application deployment, improved resource utilization, and increased scalability and portability.
Disadvantages of containerization include potential security challenges and limited compatibility with certain applications that have complex dependencies.
Conclusion
NPTEL Cloud Computing Assignment 8 2023 provides an opportunity for students to test their knowledge of cloud computing architecture and deployment models, cloud security, big data analytics, and containerization.
In this article, we have provided detailed explanations of the questions asked in the exam. Understanding these concepts can help students develop their skills and knowledge, which can be immensely valuable in today’s cloud-based IT landscape.
