1. Definition of Cloud Computing

Cloud computing refers to the delivery of computing services—including servers, storage, databases, networking, software, and analytics—over the internet, commonly referred to as “the cloud.” These services provide faster innovation, flexible resources, and economies of scale. Instead of owning computing infrastructure or data centers, organizations can rent access to anything from applications to storage from a cloud service provider. This model reduces the

Q2. a. Discuss the AWS Architecture and Framework

1. Identify the Components of Amazon S3

Ans 2.

1. Overview of AWS Architecture

Amazon Web Services (AWS) offers a comprehensive and evolving cloud computing platform that includes infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) offerings. The AWS architecture is designed to provide high availability, scalability, fault tolerance, and security. It includes various regions, availability zones, and edge location

1. Explain the Service Models of Cloud

The service models of cloud computing represent the categories of services delivered through the internet. These models define the levels of control and responsibility between cloud providers and consumers. The three primary service models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides the most basic cloud services, offering virtualized computing infrastructure over the internet. It includes servers, storage, and networking hardware, along with virtualization. Users are responsible for managing operating systems, applications, and runtime. Examples include Amazon EC2 and Google Compute Engine. PaaS builds upon IaaS by providing not only infrastructure but

 

Q5. a. Strategies to Mitigate Vendor Lock-In

1. List the Steps in Cloud Application Development

Ans 5.

1. Strategies to Mitigate Vendor Lock-In

Vendor lock-in occurs when a customer becomes dependent on a single cloud provider and finds it difficult to migrate to another provider due to technical, contractual, or financial constraints. One effective strategy to mitigate vendor lock-in is adopting open standards and APIs that are widely supported across platforms. This ensures compatibility and simplifies migration. Another strategy is using containerization technologies like Docker and Kubernetes. Containers abstract the application from the underlying infrastructure, enabling it to run on any platform that supports the container runtime. Organizations should also design cloud-agnostic

 

Q6. a. Classify the Types of Blob Storage

1. Explain the Features of VPC

Ans 6.

1. Classify the Types of Blob Storage

Blob storage is designed to store large amounts of unstructured data such as images, videos, documents, and backups. In cloud platforms like Microsoft Azure, blob storage is classified into three main types based on data access patterns and cost: Hot, Cool, and Archive tiers. The Hot tier is intended for data that is accessed frequently. It offers the lowest access latency and highest retrieval speed but comes at a higher storage cost. This tier is suitable for active web content, streaming
