Cloud Computing Overview:
Cloud computing refers to the delivery of computing services (such as servers, storage, databases,
networking, software, analytics, and more) over the internet. Instead of owning and maintaining physical
servers and data centers, individuals and organizations can access these resources on-demand through a
cloud service provider. Cloud computing offers several benefits, including scalability, flexibility, costeffectiveness, and the ability to focus on core business objectives without worrying about infrastructure
management.
There are various cloud deployment models:
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud
4. Community-Cloud
Cloud computing also has several service models:
1. Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet, such as
virtual machines, storage, and networking.
2. Platform as a Service (PaaS): Offers a platform that allows developers to build, deploy, and manage
applications without worrying about the underlying infrastructure.
3. Software as a Service (SaaS): Delivers software applications over the internet, eliminating the need for
local installation and maintenance.
