Public Cloud

While the public cloud has gone mainstream, the bulk of the organization's IT expenditures are still on-premise. Organizations will continue to modernize their core applications, allowing them to leverage the public cloud as a strategic tool for digital transformation. This will drive business agility and innovation.

The public cloud is a type of computing that makes resources available to the public via the internet. These resources may include storage capabilities, applications, or virtual machines. Overall, it will allow for scalability and resource sharing that would not otherwise be possible for a single organization to achieve.

The Public Cloud Solution

The public cloud is always hosted by a third-party provider such as AWS, Azure or GCP. These providers make it easy for the organization to access while being relatively inexpensive to maintain and scale. The public cloud solution is ideal for smaller companies that can't afford the expense of maintaining their own IT datacenters. The public cloud environment, however, makes it a higher security risk than other options. Companies storing sensitive data in a public cloud need to be aware that their data could be compromised far more quickly.

Organizations share the computing resources and are leveraged as needed. The ability to access any applications on any device that is connected to the Internet is a key advantage to the public cloud. In addition, the public cloud utilizes built-in redundancies to prevent any data loss. This will aid in disaster recovery efforts if they ever arise.

Public clouds have three common structures. These are dependent upon the type of service being provided.

SaaS

SaaS is Software as a service and is the model that distributes software on the cloud. These applications are accessed via the internet eliminating the need for users to install any software. Ultimately, reducing hardware needs so organizations can scale down support and maintenance expenses.

PaaS

PaaS is Platform as a service and is the model that allows organizations to develop software without maintaining the infrastructure. This is delivered through a broadband connection. PaaS will include version control and compile services, coupled with computing and necessary storage resources for the software.

IaaS

IaaS is an Infrastructure as a service and is the model organizations utilize to outsource its entire data center to a cloud provider. The cloud provider will host storage, servers and network hardware, and it will maintain virtualization of the environment. Iaas will help your organization with cloud adoption. It will be more cost-efficient than purchasing and maintaining all the of equipment on-premise.

All options allow an organization to scale at an unlimited rate. This is beneficial as business grows, IT will not need to acquire additional on-premise equipment. Furthermore, all cloud-based applications will remain up to date as the cloud provider is responsible for the latest features and security.

Financially, a public cloud strategy offers organizations a way to grow at scale without accumulating substantial costs. Providers offer per-per-usage deals that allow organizations to pay only for the resources they use. Thus transferring the costs from CapEx to OpEx. As an operational cost, public cloud services can protect an organization's budget from high up-front capital investments.
