This article on the migration of physical machines to the VMware virtual environment will be a two-part series.
In this first part, we will take a look at the following:
- Difference between Physical and Virtual infrastructure
- Benefits of migrating to a virtual environment
- Pros and Cons of Virtual environment
- How to move from physical to virtual
- Considerations to be checked before migration
In the second part, we will take a look at the overview of VMware free migration tool – VMware vCenter Converter, and how to perform P2V migration using it.
Difference between the Traditional Physical & Virtual infrastructure
Traditional Physical Infrastructure
In this, the resources and components of a physical server are not shared between multiple users. Each physical server includes own memory, processor, network connection, hard drive, and an operating system (OS) for running programs and applications.
Typically, in the physical infrastructure, the servers don’t have a sufficient amount of resources or they don’t completely utilize the allocated resources such as CPU, RAM, Storage. This is because many of the servers sit idle as the workload is distributed to only a few servers on the network. In addition to that, the physical servers also consume a lot of power and require separate maintenance.
Virtualization means the creation of virtual resources such as a server, desktop, operating system, file, storage or network. Virtualization allows you to utilize the computing resources completely by partitioning a physical server into multiple virtual servers, defining each server a specific OS and application. These virtual servers look and act like a physical server but are highly scalable and resources can be used efficiently.
