The term cloud infrastructure is used to describe those elements necessary for cloud computing , including the hardware system, the extracted resources, the storage and the network resources. Think of cloud infrastructure as a necessary set of tools to design a cloud; therefore, you need it to host cloud services and applications.
The virtualization technology is used to extract resources from the hardware system physical and group them in the clouds, while software automation tools and management allocate these resources and implement new environments so that users can access what they need, when they need it.
The term cloud infrastructure is also used to describe a complete cloud computing system, once all the pieces are combined. Just as the term “IT infrastructure” is used to describe various technologies that, taken together, function as the basis for various computer systems in a company,
The term “cloud infrastructure” can also be used to describe technologies that, when designed together, serve as the foundation for executing operations in a cloud environment. It is a typical example of something that becomes more important than the sum of its parts.
Therefore, for the cloud infrastructure to work, all of this technology must be enabled. And that depends on the operating system , which is probably the most ignored technology of all.

What does the cloud infrastructure include?
The cloud infrastructure is made up of several elements, integrated together into a single architecture that supports business operations. A typical solution may consist of hardware, virtualization, storage, and network elements.
Elements of cloud infrastructure
Although it is common to think that clouds are totally virtual, they need to have hardware systems as part of the infrastructure.
A cloud network consists of several physical hardware systems that can be located in different geographic locations.
The hardware system includes network equipment such as switches, routers, firewalls, and load balancers; storage matrices; devices for backups and servers.
Virtualization connects servers, and divides and extracts resources so that users can access them.
Virtualization is a technology that separates IT functions and services from the hardware system.
The software system called hypervisor controls the physical hardware system and extracts resources from the machine, such as memory, computing power, and storage.
Once these virtual resources are assigned to centralized groups, they are considered clouds.
These provide you with certain benefits, such as self-service access, automated infrastructure expansion, and dynamic resource pooling.
Within a single data center, data can be stored on multiple disks in a single storage array. Storage management ensures adequate backup of data, regular removal of outdated backups, and indexing of data so that it can be recovered in the event of any storage failure.
Thanks to virtualization, storage space is removed from hardware systems so that users can access it as cloud storage .
When storage becomes a cloud resource, you can add or remove drives, reuse hardware, and respond to changes without manually adding storage servers for each new initiative.
A network consists of physical cables, switches, routers, and other equipment. Virtual networks are created based on these physical resources.
A traditional cloud network configuration consists of multiple subnets, each with different levels of visibility. The cloud enables you to create virtual local area networks (VLANs) and assign static or dynamic addresses, as needed, for all resources on the network.
Users obtain resources from the cloud over a network, such as the Internet or an Intranet, allowing them to access cloud applications or services remotely, as needed.
