Infrastructure is the framework that aids an organization or system. In the world of computers, information technology infrastructure contains both the virtual and physical resources that help in the storage, flow, analysis, and processing of data. These infrastructures can either be decentralized or centralized. Centralized infrastructure is located within one data center while decentralized infrastructures are spread to several data centers that are run by the company or outsourced from a third party firm, like cloud provider or colocation facility.

The infrastructure found within a data center includes buildings required to support the hardware of the data center, cooling, and power. The hardware infrastructure of the data center involves storage subsystems, servers and other network appliances like the network firewalls.

The security of the data center infrastructure should carefully be considered. The building that hosts the data center needs to be heavily guarded through constant human and video surveillance and ensuring that the access to storage spaces and servers is controlled. This will make sure that only the authorized persons can access the hardware of the data center and thus reduce the risks of data theft or malicious damage.

The internet infrastructure found outside the data center which includes network components and transmission media that regulate the transmission paths. These infrastructures are built, operated and designed by the internet service providers like AT&T and Verizon.

Cloud computing is changing the design and implementation of data center infrastructures. Unlike the private data centers which require a lot of capital, cloud computing allows companies to access data services and support for free. This Infrastructure-as-a service (Iaas) approach will enable users to compute efficiently and with great flexibility. Users can enjoy computing and storage services without investing in those resources in their localities and adjust the use of the infrastructure as the workload increases.

Infrastructure-as-a service

The Software- as- a- service (Saas) model provides the same benefits for specific workloads. In this case, a third-party provider hosts the software, servers, storage, infrastructure components, and hardware. It allows users to access hosted workloads provided by the third firm instead of deploying and maintaining the workloads locally.

Traditionally, organizations were required to follow a formal process of setting a data center. This involved accessing and analyzing business objectives, design, and architectural decisions, maintaining and optimizing the infrastructure. The process involves careful selection of components, quality construction methodologies, and detailed expertise.

However, ICT infrastructure management is ever changing. The traditional infrastructure development required enormous optimization, management efforts, and integration.

Today, there is a converged infrastructure model that has preoptimized and reintegrated network and storage equipment that has changed the virtualization and IT hardware into one system. This has produced a single vendor who provides tighter ICT infrastructure management and integration over virtualization, compute and storage. The
advanced approach is known as hyper-converged infrastructure (HCI)

No matter how it was created, a good IT infrastructure must provide a base for all crucial IT functions and applications that an organization needs. This implies that the design of an IT infrastructure must help in efficient ICT infrastructure management. Software tools must give room for IT administrators to configure operating data of any device within the infrastructure. This single motive results in efficient and effective ICT infrastructure management. Proper ICT management allows administrators make good use of resources for various workloads and to comprehend the changes associated with the interrelated resources.

ICT infrastructure management is subdivided into various categories. For instance, Building Management System (BMS) offers tools that report on the parameters of the data center like efficiency, power consumption, cooling and temperature operation, and security activities.

System management incorporates tools that the IT team uses to manage and configure servers, network and storage devices. System management is nowadays supporting public and private cloud resources. Management tools are using automation to improve their efficiency and service delivery.

The primary objective of ICT infrastructure management is to employ repeatable and proven processes to offer a good environment for all people using the technology. It involves designing and implementing the right IT strategy for your organization. This will enable data-driven decisions and insights in your organization. It will improve the overall performance and productivity of the entire organization. It will help users detect problems early enough and take appropriate action.
