INTRODUCTION

1.1 Definition and Concept of Cloud Computing

Cloud computing is a technology paradigm that involves delivering various com-
puting services over the internet. It allows users to access and use a wide range
of resources, such as servers, storage, databases, networking, software, and more,
without the need for them to own, manage, or maintain the underlying physical in-
frastructure. Cloud computing is based on the concept of delivering on-demand,
scalable, and often virtualized resources to users or organizations, offering several
key features and benefits:

1.On-Demand Self-Service: Users can provision and manage computing re-

sources as needed, without requiring human intervention from the service provider.

2. Broad Network Access: Cloud services are accessible over the internet
from a wide range of devices, such as laptops, smartphones, and tablets.

3.Resource Pooling: Cloud providers pool and share their computing resources
to serve multiple customers, optimizing resource utilization and efficiency.

4. Rapid Elasticity: Cloud resources can be scaled up or down quickly to

accommodate changing workloads, ensuring that users pay only for the resources
they actually use.

5. Measured Service: Cloud computing services are metered, meaning users

are charged based on their actual consumption, which can be more cost-effective
than traditional IT models.

Cloud computing is often categorized into three primary service models:

Department of Computer Science & Engineering,SKIT, Jaipur 1

 1. Infrastructure as a Service (IaaS): In IaaS, users can rent virtualized com-
puting resources like virtual machines, storage, and networking. This allows users
to have more control over the underlying operating systems and applications while
reducing the burden of managing physical hardware.

2. Platform as a Service (PaaS): PaaS provides a higher-level environment for

developing, testing, and deploying applications. It includes tools and services for
building and managing applications without having to worry about the underlying
infrastructure.

3. Software as a Service (SaaS): SaaS delivers fully functional software appli-

cations over the internet on a subscription basis. Users can access and use software
without worrying about installation, maintenance, or infrastructure management.

In addition to these service models, cloud computing is also often categorized

into deployment models:

1. Public Cloud: Public cloud services are owned and operated by third-party
providers and are made available to the general public. These services are accessible
over the internet and are typically more cost-effective due to economies of scale.

2. Private Cloud: Private clouds are dedicated to a single organization and

are hosted on-premises or by a third-party provider. They offer more control, secu-
rity, and customization options, making them suitable for organizations with specific
compliance or security requirements.

3. Hybrid Cloud: Hybrid clouds combine both public and private cloud re-
sources, allowing data and applications to be shared between them. This approach
provides flexibility and can be useful for businesses with variable workloads.

4. Community Cloud: Community clouds are shared by a specific group of or-

ganizations, such as those with similar compliance requirements or industry-specific
