Cloud migration deployment models refer to the various ways in which an organization can deploy its applications and infrastructure in the cloud. There are three primary cloud deployment models:
Public Cloud Deployment
Using public cloud infrastructure from third-party cloud services providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform is part of this technique (GCP). In addition to managed services like databases and security, public clouds offer a range of services like computing, storage, and networking. The adoption of a public cloud enables scalability, flexibility, and cost savings because businesses only pay for the resources they really utilise.
Private Cloud Deployment
Using cloud infrastructure that is exclusive to one organisation is known as private cloud deployment. This can be hosted on-site or in a data centre operated by a different entity. Since an organisation has complete control over the infrastructure and may tailor it to suit its particular needs, private clouds offer more control and security than public clouds. Due to the need for the company to invest in its own infrastructure, private cloud deployment might be more expensive than public cloud deployment.
Hybrid Cloud Deployment
Hybrid cloud deployment uses both public and private cloud infrastructure to satisfy the unique demands of the enterprise. An organisation might, for instance, deploy public cloud infrastructure for non-sensitive workloads and private cloud for applications that are mission-critical and demand more protection and control. With using a hybrid cloud deployment, you have more control and security than with only a public cloud deployment and the freedom to select the cloud architecture that is best for your workload.
Apart from these, there are less commonly used methods like Multi-Cloud Deployment and Distributed Deployment methods.
