What are the steps used to design and deploy a cloud architecture?

"When I am designing and deploying a cloud architecture, I use three distinct steps in the process. The first is to develop a reference architecture. This is based on how the cloud resources will be used and what services the users would like to access. The next step was to create a technical architecture. This involves all the hardware, software, network, and applications required to provision the reference architecture. The final step is the deployment operation architecture. This describes how the technical architecture will be deployed and what resources will be required to keep it functioning. These resources involve the cloud provider's services and those managed by the organization's IT personnel."
