What is Cloud Computing
                     What is Cloud Computing
Introduction
• Delivery of computing services over the 
internet.
• Includes servers, storage, databases, 
networking, software, analytics.
• Users access these services on demand, 
without needing their own hardware.
• Pay-as-you-go model eliminates upfront 
investments.
• Enables flexibility, scalability, and global 
accessibility.
• Speaker Notes: Provide a simple definition. 
Define key terms like "servers" and "on-
demand." Stress that the essential idea is 
accessing resources over the internet 
instead of owning them locally.
Traditional IT vs. 
Cloud
• Traditional IT: Businesses owned and managed 
their own hardware and software.
• Cloud Computing: Businesses rent resources 
from cloud service providers.
• Traditional IT: High upfront costs, limited 
scalability, maintenance burdens.
• Cloud Computing: Pay-per-use model, rapid 
scaling, reduced IT workload.
• Speaker Notes: Contrast the old model 
(owning physical servers, software licenses) 
with the cloud's subscription-based, 
outsourced approach. Emphasize the benefits 
of the cloud.
Types of Cloud Services
Software as a Service (SaaS): Ready-to-use applications over the 
internet (Ex: Gmail)
Platform as a Service (PaaS): Tools for developers to build 
applications (Ex: AWS)
Infrastructure as a Service (IaaS): Virtualized servers, storage, 
networking (Ex: Azure)
Deployment Models
Public Cloud: Shared by multiple organizations (most common)
Private Cloud: Dedicated to a single organization (higher security)
Hybrid Cloud: Mix of public and private for different use cases
Community Cloud: Shared by organizations with common interests
 Benefits of 
Cloud Computing
• Cost savings: No hardware purchase, 
pay-as-you-go.
• Scalability: Easily add resources as 
needed.
• Reliability: Cloud providers have 
redundant systems for uptime
• Accessibility: Work from anywhere with 
an internet connection
• Agility: Innovate faster with readily 
available tools
• Speaker Notes: Hit the big selling points!
