Public Cloud-Advantages of Public Cloud Service

Public cloud is the most common type of cloud computing deployment.

A third-party cloud service provider owns and operates the cloud resources such as servers and storage, which are delivered over the internet. The cloud provider owns and manages all hardware, software, and other supporting infrastructure in a public cloud. Amazon Elastic Compute Cloud (Amazon EC2), Microsoft Azure, Google App Engine, IBM Cloud, and others are popular public clouds.

In a public cloud, you share the same hardware, storage, and network devices as other organizations or cloud “tenants,” and you use a web browser to access services and manage your account. Web-based email, online office applications, storage and testing, and development environments are all common uses for public cloud deployments.

Advantages of Public Cloud

  • Management of infrastructure is simple because public clouds are managed by a third party, it is a simple and trouble-free system. There is no need for a company to develop its own software because it is handled by a third party.
  • The costs are low. There is no need to invest in software or hardware because you only pay for the services you use.
  • Up-time. Expect to be up and running 24 hours a day, seven days a week. Because public cloud networks are extensive, there is availability and improved operation time.

Characteristics

The public cloud has a multi-tenant architecture. This architecture enables one user to share resources while keeping data isolated from other users. The ability to transmit data quickly is dependent on network connectivity. It can be used to assemble a large amount of data resources while remaining cost-effective. The public cloud allows us to access the cloud from any device at any time. As a result, the device frequently has to perform a small amount of computation, or even none at all. The structure of public clouds is determined by the structure provided. A brief description of the three most commonly used models on the market:

  • Saas

The software that is hosted in the cloud is distributed by the provider in the Software as a Service (SaaS) cloud model, and the application is accessed by the user via the internet. As a result, the user does not need to install the application software on their systems. This results in less hardware and, as a result, lower maintenance costs.

  • PaaS

The Platform as a Service (PaaS) cloud model allows an organization to develop software without having to worry about the lower levels or the type of infrastructure. The service provider provides an ideal environment, which may include version control and is delivered via a broadband connection.

  • IaaS

The entire data is outsourced by the organization to the cloud service provider in the Infrastructure as a Service (IaaS) cloud model. Everything, from the application hardware to the network hardware, is hosted on the server-side, and service virtualization is maintained. It simplifies the cloud adoption process. IaaS simplifies cloud adoption. Because everything is hosted on the server, this model is more cost-effective than others because it reduces hardware and maintenance costs. When a company grows, it is not necessary to purchase additional hardware or extend the network.

Similarly, Cloud-based applications typically require less hardware and, as a result, require less maintenance. In other words, the user does not need to worry about installing or modifying applications on their own. Instead, the corresponding host applications are kept up to date in terms of security and other features. The following are the key characteristics of the public cloud:

  • Scalability 
  • Cost-effectiveness
  • Reliability
  • Flexibility
  • Location Independence
  • On-demand computing
  • Pay per use pricing
  • broad network access
  • Resource pooling
