The main components of the virtual infrastructure
Virtual infrastructure (VI) is the creation of a virtual environment that emulates the functionality of physical equipment. Virtual infrastructure involves abstracting physical resources (CPU, memory, storage, network) and then representing them as virtual resources that can be dynamically allocated and managed. Implementation of VI allows optimizing the use of computing resources, increasing flexibility and reducing IT infrastructure costs.
In simple terms, a virtual infrastructure is a private cloud that is deployed on the provider’s hardware and software resources.
Cloud computing
Cloud computing is a fundamental aspect of virtual infrastructure. The delivery of computing resources (servers, storage, networks, and applications) occurs over the Internet.
Cloud platforms provide virtualized resources in the volume that the client needs. Resources can be provisioned and managed on demand, providing flexibility and the necessary scalability.
Definition and Features
So, we understand that cloud computing is the provision of computing services from a provider wordpress web design agency to a client in the cloud. Instead of having to own your own data centers and maintain them, you can access these resources on demand (and pay only for what you use).
Wide network access. Cloud services are accessible via the Internet, allowing you to access them from anywhere with a connection.
Pooling of resources. Cloud providers pool their resources to serve multiple clients at once. This results in more efficient use of resources, economies of scale.
Rapid scalability. Cloud resources can be quickly allocated and scaled depending on customer demand. Do you have an influx of traffic? Just increase the permissible load in the admin panel. This flexibility will allow you to quickly adapt your infrastructure to changing business needs in a matter of minutes or even seconds.
Measurable service. Cloud providers track resource usage, so we have more transparent information about consumption and costs.
Self-service on demand. The client can add their own infrastructure - cloud resources are provided and managed without the need for manual intervention from the service provider.
Server virtualization
Server virtualization is a key component of virtual infrastructure, which allows creating multiple virtual servers on a single physical server. It is based on a hypervisor: it abstracts physical hardware resources and presents them as virtual resources to guest OSs.
Virtualization technologies
A few words about the technologies that make virtualization possible. We have already talked about the hypervisor, but it is important that it can be of two types:
Type 1 hypervisor. It resides on top of a bare-metal server and has direct access to hardware resources. It is known as a bare-metal hypervisor.
Type 2 hypervisor: This is an application installed on the host OS.
Benefits of Virtual Infrastructure for Business
Increased flexibility: Virtual networks can be created and reconfigured quickly and easily, allowing organizations to adapt their network infrastructure to changing business needs.
Improved scalability: Virtual networks can be scaled up or down based on demand, allowing organizations to meet changing network requirements.
Network virtualization
Network virtualization is a technology that allows you to create virtual networks independent of the physical network infrastructure. We already talked about abstraction from physical resources and their presentation as virtual resources (which can be dynamically prepared and managed) at the beginning of this article. We will not repeat ourselves and move on to the role of virtual infrastructure in modern networks.
Role in modern networks
One of the main ones is a global increase in security. After all, virtual networks are isolated from each other, which increases security and reduces the risk of attacks.
And of course, simplified management. Remember: virtual networks can be managed centrally, which means that managing any complex network infrastructure is simplified. We will discuss this in more detail below.
