Currently, cloud computing is defined as “the delivery of on-demand internet computing services - typically over the internet, usually on a pay-per-use basis - usually via the internet.” The popularity of cloud computing is on the rise as people realize its advantages over traditional computing. Cloud computing provides numerous opportunities to various organizations and businesses. Companies don’t need to invest in costly infrastructure for computers and other hardware and software with cloud computing. Instead, they can rent out any technology they may need from a third-party service provider at a very affordable cost.
The term ‘cloud’ has several meanings. It may mean a cloud-shaped object or the combination of cloud and utility software such as e-mails. A cloud may also refer to a network of remote sites, including an intranet, a digital library, or an intranet server. When speaking of what cloud computing is, one generally speaks of the Internet, as well as any application that is hosted on it and is accessible by a user via the Internet.
As we all know, cloud computing essentially means that any IT infrastructure, whether bought or rented, is provided on-demand by a third-party service provider such as a hosting provider. Therefore, it is not required to be maintained. Cloud computing can either be managed or self-managed. With unmanaged cloud computing, the user is responsible for maintaining his own infrastructure. This would require the administration of servers, application hosting, and security. However, with managed what cloud computing is, a company would have the capability to manage and ensure that their own IT infrastructure is kept as well-maintained as possible.
Cloud computing involves two kinds of infrastructures: public cloud and private cloud. The public cloud refers to any cloud accessible over the Internet and is available to anyone who needs it, free of cost. On the other hand, a private cloud, like a cloud or IaaS cloud, is not publicly accessible and is only meant to be utilized by a limited number of customers.
Public and private clouds are made up of IT infrastructures such as servers, data centers, and software development infrastructures. Both have advantages and disadvantages, and it entirely depends on the kind of usage a company makes. Some businesses find that using what is cloud-based on-demand can be very helpful in saving costs, as they are not obligated to invest in on-premises equipment and/or infrastructure. Some also believe that using PaaS is better because they do not require maintenance, uptime monitoring, support, security updates, upgrading software costs, and other worries.
However, a business case for using cloud computing has to take into consideration several factors. It has to consider what kind of use will be made of the cloud-based infrastructure. Businesses that heavily rely on their IT infrastructure need to ask some hard questions, such as whether they can make the investments in their data centers and equipment anymore. They have to decide if the benefits of using cloud computing outweigh the costs involved.
Another factor to consider is whether the business case for what is cloud computing is a realistic one. In many cases, this question is answered yes, but it is only in some cases. Using what is cloud-based may not be a problem if the company uses its IT infrastructure to operate other business functions. For instance, many hospitals today use cloud-based to run their ERP system and other systems that help them with patient care. Similarly, if the business owner requires a lot of back-ends IT support and upgrades, they should continue using what is cloud-based. But if the business only utilizes IT resources to maintain its own infrastructure, then using what is on the cloud may cause some problems since these resources are expensive and are not always available when you need them.
A third consideration involves what is cloud-based and what is not. Some of the services offered through what is cloud-based are not actually offered through a data center. These include software as a service, a platform as a service, and infrastructure as a service. Platform as a service is a type of application that runs cloud-based and is not offered through a data center. And infrastructure as a service is what is provided by a data center and is not cloud-based but rather delivered as needed throughout a business.
