What is Cloud?

Cloud
refers to a large network of remote servers hosted on the internet and used to
store, manage, and process data, rather than on a local server or personal
computer.

This
allows for on-demand access to computing resources and data from any device
connected to the internet, making it possible to run applications and store
data remotely, making it more accessible and scalable.

 

What is Cloud Computing?

Cloud
computing is a model of delivering various services such as servers, storage,
databases, networking, software, analytics, intelligence, and more over the
Internet (“the cloud”) to offer faster innovation, flexible resources, and
economies of scale.

It
allows organizations and individuals to access these resources on-demand, without having
to manage the infrastructure themselves.

There are three main types of cloud computing:

Infrastructure
as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service
(SaaS). These
different models offer different levels of control and responsibility over the
infrastructure to the users, making it easier for them to focus on their core
business rather than managing the underlying technology.

 

Benefits of cloud Computing:

There
are several benefits of cloud computing, including:

Cost savings: Cloud computing can
reduce the cost of IT infrastructure and operations, as organizations only pay
for the resources they consume, rather than having to invest in and maintain
their own physical servers.

Scalability: Cloud computing makes
it easy to scale up or down as needed, without having to make a large upfront
investment in hardware and software.

Flexibility: With cloud computing,
employees can access the resources they need from anywhere, at any time, using
any device with an internet connection.

Disaster Recovery: Cloud providers
typically have robust disaster recovery systems in place, making it easier for
organizations to recover from a disaster and minimize downtime.

Improved security: Many cloud providers
offer security features and certifications that are difficult or expensive to
achieve with on premise systems.

Innovation: Cloud computing enables organizations to experiment and
innovate more quickly, as they can access the latest technologies and tools
without having to invest in new hardware and software.

 

SaaS
(Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure
as a Service) are three models of cloud computing that offer different levels
of service to customers.

SaaS
(Software as a Service):

SaaS
provides customers with access to software applications over the internet,
typically on a subscription basis.

Customers
do not need to manage or maintain any infrastructure or hardware, as everything
is provided and managed by the SaaS provider.

Examples
of SaaS applications include email, customer relationship management (CRM), and
accounting software.

PaaS
(Platform as a Service):

PaaS
provides a platform for customers to develop, run, and manage their own
applications and services.

PaaS
eliminates the need for customers to manage the underlying infrastructure, but
they are responsible for developing and deploying their applications. Examples
of PaaS include Heroku, Google App Engine, and Amazon Web Services (AWS)
Elastic Beanstalk.

IaaS
(Infrastructure as a Service):

IaaS
provides customers with access to virtualized computing resources, such as
virtual machines, storage, and networking, over the internet.

Customers
are responsible for managing the operating systems, middleware, and
applications they run on the infrastructure, but the IaaS provider manages the
underlying hardware and infrastructure. Examples of IaaS include Amazon Web
Services (AWS), Microsoft Azure, and Google Cloud Platform.

There are many vendors
that provide cloud computing services. Some of the most well-known include:

Amazon Web Services (AWS): Amazon’s cloud computing division, AWS,
offers a wide range of services, including computing, storage, databases, and
analytics.

Microsoft Azure: Microsoft’s cloud computing platform offers services for
compute, storage, databases, and more, and is integrated with other Microsoft
products, such as Office 365.

Google Cloud Platform: Google’s cloud computing platform offers services for
computing, storage,
