What is public cloud?
It is a new concept which evolved from the hybrid cloud models first developed by Google and Amazon. The first type was the Public Infrastructure Platform (PIA), which provided basic infrastructure services, such as file storage, application deployment, and e-mail services; the second was the Hybrid Infrastructure Model (HIM). The aim of both PIA and HIM was to provide a generic model for all businesses, rather than specific solutions for specific companies. With the latest evolution of these two models, called the Public Cloud Model or Cloud Computing, developers and service providers are finally able to share infrastructure and services.
This article will discuss the advantages and disadvantages of public cloud.
Advantages of Public Cloud
As the name suggests, what is public cloud is a model in which the hosted infrastructure is not dedicated to any one single organization or department. It is therefore ideal for companies that need to scale up their operations without losing their expertise or data to another source. Because the technology is based on the Internet, it is also possible to extend the services to the Internet for use anywhere in the world. This is in contrast with the traditional private cloud models, which were designed with IT infrastructures in mind. Public cloud is therefore an IT model in which a third-party host and virtual infrastructure services are managed directly by a single company and shared by multiple organizations using the same public Internet.
- Lower costs — no need to purchase hardware or software and pay only for the services used.
- No maintenance — service provider provides the maintenance.
- Near unlimited scalability — on-demand resources are available to meet business needs.
- High reliability — a vast network of servers ensures against failure.
Disadvantages of Public Cloud
On the other hand, there are some disadvantages of public cloud services. In the initial stage, it may seem to be a more economical option because it requires less server resources. Nevertheless, this can be overcome by choosing a better provider, who can guarantee the required service level. As more organizations adopt this model, more companies will need to invest in their own virtual infrastructures so as to remain competitive in the global marketplace.
A private cloud-based service can provide greater flexibility and also can offer more cost-effective options. Virtualization solutions are a great example of this, as they allow many virtual servers and platforms to be run on a common hardware platform. In the same way, virtualization software can be used to run applications across multiple private cloud infrastructures, thereby saving a great deal of money. Some of the most common uses of private cloud-based services are desktop computing, shopping carts, customer relationship management (CRM), and content moderation.
In order to take advantage of the benefits of cloud computing, a large investment in terms of time and money needs to be made. However, there are many private and public cloud service providers today, and it is possible for even the smallest organizations to use such services. This poses a challenge to IT departments, but if well-managed, public cloud-based services can provide a significant boost to an organization’s productivity.
Therefore, whether you are planning to start a business or expand an existing one, it is important for you to understand what public and private cloud-based services are, how they work, and how they can help business. IT managers can leverage a good knowledge of these concepts to improve the overall efficiency of their IT operations. In addition, IT managers should ensure that they have a good understanding of the advantages of using a public cloud service provider. They should also ensure that they have a good idea about the costs involved in opting for such a solution to minimize the risks involved and to leverage the benefits that the public cloud has to offer
Therefore, it is essential to have cloud computing as part of your IT strategy
