Public Cloud
When a Cloud computing infrastructure is maintained and managed by the single cloud service provider and the shared resource services are rendered over the network to a different customer, and the cloud customer has no physical control what so ever over the infrastructure except the connectivity is called as a Public Cloud.
Public cloud services can be free or have a comparatively lower cost of engagement. And one has to be optimal and sure on the IT security services as they are more vulnerable to the attacks as the services been provided over the publically shared infrastructure i.e. (Applications, Storage, and other resources, etc). Few known service providers in the public domain are Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, etc.
Private Cloud
When a Cloud computing infrastructure is been solely hosted, Collocated, or on-premise and been maintained and managed by the cloud service provider with the dedicated resources services and cloud customer has physical control over the infrastructure hosted internally or externally is called as a Private Cloud.
The cost of engagement is on the higher end and majorly depending on the infrastructure hosting model as to be in the self-run data center or on the Cloud service provider location and one can optimize the logical and physical security as per the standards and organization norms to achieve the service requirement. Few known services for a private domain are Rackspace, VMware, SUSE Cloud, Openstack, etc.
Hybrid Cloud
When a Cloud computing infrastructure is the composition of public, private and community as a distinct entity and is bounded together as a solution offering for the benefit of the multi deployment model on the optimize requirement of the extended on-demand services from the different cloud service provider which allows extending cloud services capacity and capability by aggregation, integration or customization with another cloud services is a Hybrid Cloud.
The engagement of the cloud bursting as an application deployment model in which application runs in the private cloud and scale across the public or community cloud as required on demand of the performance and capacity of the resource for a certain period of time and organization pays only for those extra resources as utilize on demand for the specific period of time is a feasibility provision on hybrid cloud.
Community Cloud
When a cloud computing infrastructure is shared between several organizations with common goals and concerns and managed or hosted by the third parties, externally or internally across the organization. The cost of engagement spread across the organizations as an individual contribution to a particular community.
The community share similar requirement of privacy, performance, security compliance, jurisdiction, etc.

About :- The red-naped ibis (Pseudibis papillosa) Also known as the Indian black ibis or black ibis is a species of ibis found in the plains of the Indian Subcontinent. Unlike other ibises in the region it is not very dependent on water and is often found in dry fields a good distance away from water. It is usually seen in loose groups and can be told by the nearly all dark body with a white patch on the shoulder and a bare dark head with a patch of crimson red warty skin on the crown and nape.

Like any other Operating System (OS). Linux is an alternative OS for DOS, UNIX, Mac OS and Microsoft Windows platform. Linux belong to the family of "free and open source software" (FOSS). On September 17, 1991 the first distribution of LINUX kernel was released by "Linus Torvalds" freely. Later the project was taken up by open-source software collaboration community, which eventually contributed to todays multiple flavours distribution.
Linux was originally developed for personal computers based...

Step 1: Choosing Linux Distribution and downloading it.The world of Linux is free open-source software with hundreds of active Linux distributions, and dozens of different desktop environments you could run on them. Linux distributions combine the Linux kernel with other software like the GNU core utilities, X.org graphical server, a desktop environment, a web browser, and more. To form a single operating system you can install. Do check...

What is Cloud Computing?
To be precise Cloud computing is a concept to leverage the IT infrastructure and support to optimize liability of the capital expenditure and risk to maintain and provide the digital services.
To be very simple its a pool of shared services offered and delivered on-demand often over the internet as required on dynamically configurable system resources and manageable higher-level services that can be provided with minimal downtime and effort in term of computing services...

As per NIST, there are three services offering model for Cloud services as IAAS, PAAS, and SAAS
Infrastructure as a service (IaaS)A cloud-based computing solution offering, where a complete infrastructure is been outsourced. Where a service provider delivers a complete set of preinstalled and configured hardware or software or both usually a LAMP or WAMP stack on a virtualized or containerized and sometimes physical...
