What is Cloud? Need to Know

Updated: Jan 19


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,
