A public cloud is a platform that uses the typical cloud computing concept and is third-party managed to offer resources and services to remote users anywhere in the world. Databases, load balancers, management tools, firewalls, and other platform-as-a-service (PaaS) or software-as-a-service (SaaS) components are just a few examples of the types of workloads that can be included in services. The next step is for users to put together resources and services to create an infrastructure that can deploy and run enterprise workloads. Public cloud services may be provided without charge or in accordance with a number of subscription or on-demand pricing models, such as pay-per-use or pay-as-you-go (PAYG) models.
Public cloud services
Public cloud computing services are currently offered in a wide range of offers and service models. The cloud can now supply almost any service that doesn't require being physically close to the hardware that is hosting it. The following are the top three cloud service models:
Using the open Internet or dedicated connections, the public cloud provider provides on-demand access to basic computer, network, and storage resources. This could involve direct access to the underlying hardware, or "bare metal," but access to virtualized resources is far more common.
Application developers can build, run, and manage apps on a full platform that includes all essential infrastructure, software, and hardware. Users don't need to worry about minute details since the cloud provider normally manages the complete platform architecture.
Users can access software that is hosted in the cloud with SaaS. These programs are hosted in the cloud and accessed using a web browser or an API rather than being installed on local devices.
Other (typically more specialized) service models are also available. Offerings such as Business-Process-as-a-Service (BPaaS), in which an entire horizontal or vertical business process is delivered as a combination of similar IaaS, PaaS, and SaaS services, or Function-as-a-Service (FaaS), a subset of SaaS where application code operates only in response to particular events or requests, are examples. However, the vast majority of these products are variations or extensions of the three core cloud computing service models.
Benefits and challenges of public cloud
In contrast to on-premises data centers, public cloud solutions allow businesses to scale at an almost endless rate. As a company grows, it does not need to buy more hardware or manage a large network. Similarly, cloud-based services and apps use significantly less hardware than traditional applications. In other words, consumers no longer need to bother about installing and updating software on their computers. Instead, their cloud-hosted applications will always have the most recent features and security.
A public cloud strategy allows organizations to grow at scale without incurring high costs. Per-usage deals are available from providers such as Amazon Web Services, Google Cloud, and Microsoft Azure, allowing organizations to pay only for the services they use. Public cloud services, as an operating cost, can safeguard an organization's budget from large upfront capital investments.
Despite the fact that security is a top priority for public cloud providers, some companies opt to host their data on a privately managed cloud to keep it safe. Organizations in highly regulated areas, such as healthcare, may gain the most from a hybrid model. Established enterprises with extremely specialized computing demands may prefer a private or hybrid approach for improved resource optimization.
Why Public Cloud?
Utilizing the public cloud can save businesses money in a variety of ways:
Lower equipment purchase costs
Because employees can only use and pay for cloud-based resources when they need them, employing public cloud-based desktops and applications is frequently less expensive than buying physical IT equipment or software that may or may not be utilized and must be maintained.
Lower equipment maintenance costs
The expenses of maintaining IT equipment are also passed on to the cloud service provider when using public cloud-based services. Migrating applications to the public cloud may be easier for a small or new business; organizations with a large legacy IT infrastructure and applications have more to consider and plan for. However, an increasing number of large firms are turning to the public cloud as part of a multifaceted IT strategy. In this manner, they may reap the benefits of the public cloud while simultaneously retaining the advantages of on-premises architecture and private cloud choices.
Public cloud - Conclusion
Specialized security personnel are used by providers to automate security activities and monitor the system for abnormalities. Strict controls prevent other cloud tenants from accessing user data. A public cloud solution within a hybridized environment can be utilized by organizations to gain access to extra levels of protection.
Many organizations are aiming to utilize a combination of public and private clouds to obtain more agility and control, and they require a solution to manage hybrid multi-cloud setups.

A: There are numerous benefits of having a public cloud which includes lower costs, no maintenance, and near-unlimited scalability.
A: The public cloud is great for such organizations which have a better prediction of their requirements in the initial stage and later it can scale up or down based on their workload.
A: There's a general perception among people that the private cloud is more secure, although the public cloud is generally better in security since it has security experts for maintenance and continuous upgradation based on current vulnerability and its mitigations.
A: Besides lower cost and scalability, the public cloud's best benefit is to get free from a physical hard drive. It offers its users with remote sharing and accessing ability which makes things convinent.
