Public cloud is a type of computing where resources are offered by a third-party provider via the internet and shared by organizations and individuals who want to use or purchase them.

Simply put, cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

To summarize, Private Clouds are where your data is stored in a data center sectioned specifically for you, which may or may not be on your infrastructure, and Public Clouds are where your data is stored over public data centers which are on the infrastructure of your Cloud Service Provider.

The cloud resources (like servers and storage) are owned and operated by a third-party cloud service provider and delivered over the internet. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by the cloud provider. Microsoft Azure is an example of a public cloud.

The correct answer is c) Data resides on a server (computer) that you access via the internet.

There are also three main types of cloud computing services: Infrastructure-as-a-Service (IaaS), Platforms-as-a-Service (PaaS), and Software-as-a-Service (SaaS).

These include data storage, servers, databases, networking, and software.

In its simplest, a private cloud is a service that is completely controlled by a single organization and not shared with others. While a public cloud is a subscription service that is also offered to any and all customers who want similar services.

Public Cloud Services

The IaaS provider offers virtualized computing resources such as virtual machines (VMs) over the internet or via dedicated connections. Examples include Amazon Web Services(AWS), Microsoft Azure, IBM, and Digital Ocean.

Public cloud makes computing resources available to anyone for purchase. Multiple users typically share the use of a public cloud. In contrast, private cloud involves cloud-based services that are hosted within an organization's own private servers.

Public cloud is also internal to an organization as it is generally implemented within the infrastructure and resources of the organization.

Advantages of public clouds: Lower costs—no need to purchase hardware or software, and you pay only for the service you use. No maintenance—your service provider provides the maintenance. Near-unlimited scalability—on-demand resources are available to meet your business needs.

The public cloud increases the risk of threats like identity fraud and phishing attacks.

The Public cloud has an architecture which is a multi-tenant and it enables the user to share the resources of the computers. To share the computing resources the data of each tenant remains isolated from other tenants. It rapidly transmits the data and relies on high-bandwidth network connectivity.

Private cloud providers include Hewlett Packard Enterprise (HPE), Dell, IBM, Oracle, and some familiar names from the public cloud provider space, including AWS, Google, and Microsoft.

Public cloud resources are typically available on a pay-per-usage basis. Other services may be free to access or sold on a subscription-based model. Common public cloud examples include services like Amazon Web Services, Gmail, Google Drive, and Hotmail.

Question 63: Which data may not be suitable for public clouds? Explanation: Not all applications and their data are suitable for public cloud use. Legacy applications, mission-critical workloads and sensitive data — such as credit card information — may not be the best fit for a public cloud environment.

The five layers are the Physical layer, virtual layer, control layer, service orchestration layer, and service layer. Cloud Computing reference model is divided into 3 major service models: Software as a Service (SaaS)

Security: Code, Container, Cluster, and Cloud.

What is meant by 5 4 3 in cloud computing? ›

The 5-4-3 represents the creation of a single collision domain, and the numbers are maximums: (5-) no more than five segments between any two nodes that communicate with each other, (-4-) no more than four repeaters in those five segments, and (-3) no more than three of the five segments can have active devices ( ...

There are four cloud deployment models: public, private, community, and hybrid. Each deployment model is defined according to where the infrastructure for the environment is located.

Cloud architecture components include:

A frontend platform. A backend platform. A cloud-based delivery model. A network (internet, intranet, or intercloud)

The fundamental building block of cloud computing infrastructure is the server. Cloud computing servers are basically computers on which online applications can be run and data can be stored. When provided by an IaaS vendor, cloud servers can also be real or virtual.

Cloud computing is believed to have been invented by J. C. R. Licklider in the 1960s with his work on ARPANET to connect people and data from anywhere at any time.

Emails, calendars, Skype, and WhatsApp are cloud computing examples that we use every single day. They make use of the cloud feature of remote accessibility of data to support our data in the cloud infrastructure, helping us access them thru the Internet anytime, anywhere.

That's why it's essential for users to understand cloud analytics and the five V's of big data: volume, variety, velocity, veracity and value.

PHP. PHP is a programming language widely used for web development and cloud computing because it is easy to learn and manipulate. Therefore, it is popularly implemented while automating websites and other similar applications.

Software-as-a-Service (SaaS)

SaaS is another important cloud computing term and is referred to all the software applications owned and run off-premises that are offered by a cloud service provider. To give an example, Google Docs is one such application that lets users use it no matter where they are in the world.

How do you explain cloud computing to a layman? ›

In the simplest terms, cloud computing means storing and accessing data and programs over the internet instead of your computer's hard drive. (The PCMag Encyclopedia defines it succinctly as "hardware and software services from a provider on the internet.") Ultimately, the "cloud" is just a metaphor for the internet.
