Defining virtualization in cloud computing

Virtualization is the premiere trend among computing and network engineering, and yet not a new idea. In fact, virtualization has existed in the form of Logical partitions for IBM mainframes and VLAN’s. In any case, soon to take over as the main job source for engineers and contractors in the IT world, demand for virtualization and cloud computing is high, even if those who demand it know nothing about it.

Virtualization refers to virtual machines, machines that do not have the physical hardware of their former computing components, but still act as though they do. These virtual machines believe they have the same type of hardware, software, and firmware, so they work the same way that other computers would. This virtualization in all its different forms is the foundation of cloud computing, without which cloud computing could not exist.

Within the world of cloud computing, a great deal of regular computer activity and storage is not held on physical machines anymore, but rather, inside of a cloud, a virtual computer. So how does visualization exist within cloud computing? And how can anyone really understand it? With AWS Training, companies get the know-how to better understand how virtualization is the backbone of cloud computing.

Virtualization is really a pillar of cloud computing, particularly with regard to internal cloud architecture. Virtualization in cloud computing is the ability to divide one hardware device or infrastructure into different logical components all of which are separate.

Virtualization is really the key to building cloud based architectures. The reason for this is that it allows for more flexibility which means better use of the underlying equipment. Rather than requiring separate pieces of physical equipment for each tenant (or company employee), multiple tenants can be separated logically on one piece of infrastructure. This is also referred to as multi-tenancy. Depending on the actual infrastructure that is being designed, the tenant in question can be an individual application, a team or department within your company, or an external customer.

When you use virtualization for cloud computing, there are three areas on which to focus.

1) Server virtualization

The first area is server virtualization. Server virtualization generally allows a single physical server to be divided into different subsets, by creating virtual hardware. The virtual hardware has an operating system and an application suite installed on it after which it operates like an independent server. OS Based virtualization operates services or applications within an OS which give users the ability to make virtual servers. Bare metal virtualization on the other hand installs a lightweight virtualization capable OS onto server hardware, so that it can then create virtual servers. The latter is more popular for production uses.

Benefits to cloud environments include increased server usage and operational flexibility. With increase server usage, less hardware is required to perform the same computer based tasks, something which reduces overall company costs. Increased flexibility is what creates cloud architectures.

2) Network virtualization

Network virtualization exists in many forms. VLANs, for instance, allow single physical LAN architecture to be divided up into separate networks without separate physical connections. Virtual Routing and Forwarding (VRF) lets you create separate routing tables on one piece of hardware, something you can use to support different routes for any number of purposes. These tools can be used simultaneously to provide the underlying architecture for cloud computing. Benefits include increased flexibility and utilization.

3) Storage virtualization

Storage virtualization defines anything that comes from an underlying RAID configuration. Consolidated storage is an important part of cloud infrastructure. Having data in a single place simplifies infrastructure and increases the feature set. Storage needs the right protocol options and offer flexibility to adapt to changing business needs. Cloud environments can do just that. With storage virtualization companies can maintain a single copy of any duplicate data, something which reduces the overall disk usage. Companies can also optimize disk usage by assigning disks to different serves based on how much space they might need. As a result applications can grow without taking up unnecessary disk space.

Overall, virtualization is really the foundation of all cloud environments. With server virtualization, network virtualization, and storage virtualization, cloud computing is made possible. Through virtualization, cloud environments enable companies to enjoy flexibility and higher utilization infrastructures.
