What is Public Cloud? How it works and benefits?

An IT model known as the public cloud makes computing services, such as compute and storage, develop-and-deploy environments, and applications, on-demand accessible to businesses and individuals via the open internet.

A third-party cloud service provider owns and runs the servers and storage that make up the cloud resources, which are then delivered over the internet. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by the cloud provider.

The data centers used by cloud service providers are divided into virtual machines and shared by tenants. Tenants have the option of paying for additional cloud-based services like software applications, application development tools, or storage in addition to simply renting the use of those virtual machines. Businesses frequently use public cloud services to store data that does not need frequent access or for less-sensitive applications with unpredictable usage spikes.

Anyone can buy computing resources thanks to public clouds. Multiple users typically share the use of a public cloud. Private cloud, on the other hand, refers to cloud-based services that are hosted on a company's own private servers.

In order to scale their current IT resources on demand without having to commit to expanding their physical IT infrastructure, many enterprise businesses turn to public cloud services. For instance, instead of purchasing a physical desktop machine, a company can purchase a virtual desktop license. The virtual desktop can be instantly located anywhere and spun up or deactivated in a matter of minutes.

Since data stored on a public cloud is backed up and accessible from anywhere, the public cloud is also a well-liked option for storage needs. Data that doesn't need to be accessed frequently can frequently be stored in the public cloud for very little money thanks to the variety of storage options available.

How Public Cloud work?

A public cloud uses a virtualized environment to extend a business's IT infrastructure, enabling it to host some of its services and infrastructure on virtual servers that are located off-site and are owned by a different party. The strengths of public cloud service providers vary, and they provide a wide range of services and pricing structures. Companies that are thinking about moving to the public cloud should carefully weigh their provider options, especially if they will be bound by a long-term contract.

Security in the public cloud is another factor that IT managers will want to consider because servers in the cloud share data from various businesses. Data encryption is a good way to ensure greater security, but not all encryption platforms are compatible with both public and private clouds, which is what is known as a hybrid cloud. Every time data is transferred between a private data center or private cloud and a public cloud, there is an inherent security risk.

One last consideration is the location of your public cloud service provider. Many nations have laws requiring the local storage of specific types of data due to data privacy concerns. These laws change frequently, so it’s a good idea to choose a cloud service provider that is located in your country and can confirm that the servers where your data will be stored are local and in compliance with regional laws. Another problem is latency; if your data is being stored on another continent, it might take longer than if it were nearby.

Public Cloud Benefits

The following benefits of public cloud computing: 

Low Cost- Due to the fact that public clouds share the same resources with many more users than private or hybrid clouds, they are less expensive.

Independent of place- Because its services are provided over the internet, public clouds are location independent.

Save time- In the public cloud, the cloud service provider is in charge of managing and maintaining the data centers where data is stored, saving the cloud user's time when it comes to connecting to the network, launching new products, releasing product updates, configuring servers, and so forth.

Rapid and simple setup- Organizations can easily buy public cloud on the internet and deployed and configured it remotely through the cloud service provider within a few hours.

Business Agility- The public cloud offers the capability to elastically resize computer resources in accordance with the needs of the organization.

Scalability and reliability- The public cloud offers users scalable (easily added and removed) and dependable (available 24 hours a day, 7 days a week) services at a reasonable price.
