The Cloud - Most Popular Word in IT

Cloud is the most popular topic nowadays but it is not simply fashionable term in the technology, it is actually broad term. 

The cloud is something beyond the internet. It can both software and infrastructure. Where you can use technology when you need it and as long as you need it. You just pay when you use it. You do not require installing any software in your desktop at all.

Cloud models
Public cloud

A public cloud service is based on a cloud provider typically offering pre-configured and published offerings. 

They normally have an online storefront that lists all available products, configurations, options, and pricing. Because the public cloud providers are offering services to the general public and a wide variety of customers, they have implemented their own cloud management platform. The cloud platform and services offered are targeted at the widest group of potential consumers; therefore, customization of the service is normally limited.

Private cloud

Private cloud services might begin with the same basic cloud computing services
as offered by a public cloud provider, but the service can be hosted at a customer owned or contracted data center. 

Private clouds offer choices of the cloud services to be deployed, how much integration there is between services, how the management and operations are handled, and the level of security controls and accreditation.

Hybrid cloud

Hybrid cloud is a cloud computing environment which uses both private and public cloud services.

It allows to move workload between private and public clouds as computing needs and costs change. It gives businesses greater flexibility and more data deployment options.

Cloud services

It simply provides software on demand. There is no need to install; you can directly can start using required software.

A service offering that provides one or more applications to the consumer. Applications are hosted and managed by the provider in the cloud with the consumer accessing the application services from various end-computing devices such as PCs, laptops, tablets, smartphones, or web browsers.

The consumer does not manage the underlying server farm, applications, or storage. The provider might provide the consumer a web-based self-service control panel to give the consumer some control over certain aspects of the application or user configuration. Pricing to the consumer is often based on a per seat user license with potential up-charges for additional storage or application features.


PaaS environments provide you with an infrastructure as well as complete operational and development environments for the deployment of your applications.


In simple terms it provides all the data center hardware needs based on the demand. 

A service that includes processing, memory, storage, and networking in the form of a VM. Consumers can deploy operating system and applications as they prefer. Cloud providers often supply OS templates as a quick-start to get the system operational quickly.

The cloud provider also handles all systems management of backend server farms, networking, storage systems, and virtualization hypervisors with the consumer managing the OS, applications, and data.
