Cloud computing is a model that provides on-demand access to shared configurable computing resources like servers, storage, databases, networking, software, analytics and more over the internet. It has key characteristics of on-demand self-service, broad network access, resource pooling, rapid elasticity and measured service. There are three cloud service models - SaaS, PaaS and IaaS and four deployment models - private cloud, community cloud, public cloud and hybrid cloud. Cloud computing offers advantages of scalability, affordability and security.

2. CLOUD COMPUTING
• Cloud computing is a model for enabling ubiquitous, convenient, on-
demand network access to a shared pool of configurable computing
resources (e.g., networks, servers, storage, applications, and services)
that can be rapidly provisioned and released with minimal
management effort or service provider interaction.
• This cloud model is composed of five essential characteristics, three
service models, and four deployment models.

3. KEY CHARACTERISTICS OF CLOUD
• ON-DEMAND SELF SERVICE
• BOARD NETWORK ACCESS
• RESOURCE POOLING
• RAPID ELASTICITY
• MEASURED SERVICE

4. CLOUD SERVICE MODEL
• SAAS (SOFTWARE AS A SERVICE)
• PAAS (PLATFORM AS A SERVICE)
• IAAS (INSFRASTRUCTURE AS A SERVICE)

5. CLOUD DEPLOYMENT MODEL
• PRIVATE CLOUD
• COMMUNITY CLOUD
• PUBLIC CLOUD
• HYBRID CLOUD

6. ADVANTAGE
SCALABLE-
A cloud service allows quick scaling up and down of computing resources to
accommodate your changing needs.
AFFORDABLE-
You pay less for a cloud service, as it eliminates unnecessary costs involved in
hardware upgrades and maintenance.
SECURE-
By signing up for a cloud service, you are essentially making your data more secure
using their industry-grade security protocols.
