In this video, you will learn about CloudPhysics, one of the third-party solutions you can use to automatically discover your environment. CloudPhysics is a solution that monitors and analyzes IT infrastructures and offers insights and reports that help you better understand your total cost of ownership, while also allowing you to analyze the actual usage of resources over time. These capabilities enable you to make a side-by-side comparison between the total cost of running on-premise virtual machines versus running in the Cloud, and will help you choose which machines in general to migrate. CloudPhysics also helps optimize your spend in the Cloud by recommending the right size of VMs to provision based on their actual utilization. CloudPhysics provides an easy to deploy, non-intrusive virtual software appliance that is installed within your on-premise environment and just needs read-only access to VMware vCenter. CloudPhysics does not deploy any probes or agents to your VMware ESXi hosts, guest virtual machines or AWS EC2 instances. In addition, all communications are achieved through existing management interfaces and have no performance impact on your virtual machines. If you're using AWS, CloudPhysics uses the same non-intrusive approach by leveraging AWS's APIs instead of harvesting data directly from the EC2 virtual machine instances. CloudPhysics collects data from your on-premises environment using a virtual appliance called the CloudPhysics observer. Note that if you are planning a migration from an on-premise VMware environment, you need to install the virtual appliance. But if you were migrating Virtual Machines from AWS, you need to provide AWS identity and access management, also known as IAM permissions, and no installation of CloudPhysics observer is required. The CloudPhysics observer is a minimum resource appliance designed to collect data from within your VMware vCenter through read-only APIs, process the data, and share the data to CloudPhysics web portal through secure means. Observer collects your on-premise VMware based performance and configuration data in order to provide you with a holistic picture of your environment, which we explore later in this module. For more information on how CloudPhysics handles your data, see the link attached to this video, as well as installation guides for both AWS and vSphere.
