Fundamentals
Introduction
 Welcome to our presentation on "Cloud Computing Fundamentals." In today's 
digital age, cloud computing has become a cornerstone of modern technology, 
revolutionizing the way businesses and individuals access, store, and manage 
data and applications. In this presentation, we will explore the fundamental 
concepts of cloud computing, including its definition, key characteristics, 
deployment models, service models, benefits, and challenges.
What is Cloud Computing?
 Cloud computing refers to the delivery of computing services—including 
servers, storage, databases, networking, software, and more—over the 
internet ("the cloud") on a pay-as-you-go basis. Rather than owning and 
maintaining physical hardware and infrastructure, users can access 
computing resources remotely from cloud service providers, eliminating 
the need for on-premises hardware and reducing upfront costs.
 Key Characteristics of Cloud Computing
 On-Demand Self-Service: Users can provision and access computing 
resources (such as virtual machines, storage, and applications) on-
demand, without requiring human intervention from the service provider.
 Broad Network Access: Cloud services are accessible over the internet 
from any device with an internet connection, enabling ubiquitous access 
to computing resources.
What is Cloud Computing?
 Resource Pooling: Cloud providers pool and dynamically allocate 
computing resources (such as processing power, memory, and storage) 
to multiple users, optimizing resource utilization and scalability.
 Rapid Elasticity: Cloud resources can be rapidly scaled up or down in 
response to changing demand, allowing users to quickly adapt to 
fluctuating workloads and requirements.
 Measured Service: Cloud usage is metered and billed based on actual 
usage, enabling users to pay only for the resources they consume and 
providing cost transparency and control.
Deployment Models:
 Cloud computing offers various deployment models:
 Public Cloud: Services are provided over the public internet and shared 
among multiple users.
 Private Cloud: Services are dedicated to a single organization and 
hosted on-premises or in a private data center.
 Hybrid Cloud: Combines public and private cloud environments, offering 
flexibility and scalability.
Cloud computing provides different 
service models:
 Infrastructure as a Service (IaaS): Offers virtualized computing resources 
such as servers, storage, and networking.
 Platform as a Service (PaaS): Provides a platform for developing, testing, 
and deploying applications.
 Software as a Service (SaaS): Delivers software applications over the 
internet on a subscription basis.
 Infrastructure as a Service (IaaS): In the IaaS model, cloud providers 
offer virtualized computing resources over the internet. This includes 
virtual machines, storage, and networking capabilities. Users have 
control over the operating system, middleware, and applications, 
allowing for greater flexibility and customization. 
 Platform as a Service (PaaS): PaaS provides a platform for 
developers to build, deploy, and manage applications over the internet. 
Cloud providers offer development tools, middleware, and runtime 
environments, allowing developers to focus on application development 
without worrying about underlying infrastructure. PaaS simplifies the 
development process, accelerates time-to-market, and enables 
seamless integration with other cloud services.
 Software as a Service (SaaS): SaaS delivers software applications 
over the internet on a subscription basis. With SaaS, users can access 
and use applications hosted in the cloud without installing or 
maintaining them locally. Cloud providers handle software maintenance, 
updates, and support, allowing users to focus on using the software 
rather than managing it. Common examples of SaaS applications include 
email, CRM (Customer Relationship Management), collaboration tools, 
and productivity suites.
Benefits of Cloud Computing
 Cost Savings: Eliminates the need for upfront hardware investment and 
reduces operational expenses through pay-as-you-go pricing models.
 Scalability and Flexibility: Allows users to scale resources up or down 
based on demand, enabling agility and cost optimization.
 Global Accessibility: Provides ubiquitous access to computing resources 
from anywhere with an internet connection, facilitating collaboration and 
productivity.
 Reliability and Availability: Cloud providers offer high levels of 
reliability, redundancy, and uptime, ensuring continuous availability of 
services.
 Security: Cloud providers implement robust security measures and 
compliance standards to protect data and applications from cyber threats 
and breaches.
Challenges of Cloud Computing
 Security Concerns: Data security, privacy, and compliance remain top 
concerns for organizations moving to the cloud.
 Compliance and Regulation: Meeting regulatory requirements and 
industry standards can be challenging in multi-tenant cloud 
environments.
 Vendor Lock-In: Dependency on a single cloud provider may limit 
flexibility and portability of applications and data.
 Performance and Latency: Network latency and performance issues 
may arise when accessing cloud resources over the internet.
 Data Transfer Costs: Costs associated with data transfer between on-
premises and cloud environments can add up, especially for large 
volumes of data.
Uses of Cloud computing
 Cloud computing offers a wide range of uses and benefits for businesses and 
individuals across various industries. Some of the key uses of cloud 
computing include:
 Scalability and Flexibility: Cloud computing allows businesses to scale 
their computing resources up or down based on demand. This scalability 
enables organizations to handle fluctuations in workload efficiently, ensuring 
optimal performance and cost-effectiveness.
 Cost Savings: By moving to the cloud, businesses can reduce capital 
expenditures on hardware and infrastructure. Cloud computing operates on a 
pay-as-you-go model, where users only pay for the resources they consume, 
leading to significant cost savings over traditional IT infrastructure.
 Accessibility and Collaboration: Cloud computing enables ubiquitous 
access to data and applications from anywhere with an internet connection. 
This accessibility fosters collaboration among team members, allowing them 
to work together in real-time regardless of their location.
