Another foundational concept of cloud are the deployment models. A deployment model is where your infrastructure resides and also determines who has control over its management. Like the cloud computing service delivery models, it is also important to choose the deployment model that will best meet the needs of your business.
There are three types of cloud computing deployment models:
A cloud deployment means your applications are fully run in the cloud and accessible by the public. Often, organizations will choose a public cloud deployment for scalability reasons or when security is not a main concern. For example, when testing an application. Businesses may choose to create or migrate applications to the cloud to take advantage of its benefits, such as its easy set-up and low costs. Additionally, a public cloud deployment allows for a cloud service provider to manage your cloud infrastructure for you.
An on-premises cloud deployment, or private cloud deployment, is for companies who need to protect and secure their data and are willing to pay more to do so. Since its on-premises, the data and infrastructure are accessed and managed by your own IT team. Due to in-house maintenance and fixed scalability, this deployment model is the costliest.
A hybrid cloud deployment connects cloud-based resources and existing non-cloud resources that do not exist in the cloud. The most common way to do this is between a public cloud and on-premises infrastructure. Through a hybrid cloud integration, you can segment data according to the needs of your business. For example, putting your highly sensitive data on-premises while putting less-sensitive data on the public cloud for accessibility and cost-effectiveness. This allows you to enjoy the benefits of the cloud while maintaining a secure environment for your data.
