An information technology infrastructure
An information technology infrastructure (IT infrastructure) is a complex of IT programs, computer equipment and means of communication between them and the staff that use it to carry out their professional activities.
IT infrastructure must fully meet the needs of the business, and for this it needs to be properly configured.
What a well-organized IT infrastructure provides:
- Continuous operation
Modern IT-companies are required to work 24/7, and even short-term failures can lead to large financial and reputational losses.
It is better to prevent failures and problems at the first stages than to correct them later.
In order to do this, large companies use monitoring systems that inform administrators about problems in the IT-infrastructure before these problems can lead to unpleasant consequences.
In order to improve scalability, companies use unified solutions – starting with the similar configurations of operating systems and software and ending with templates and scripts for deploying the infrastructure of entire branches (bank branches or retail stores). As a rule, the more processes in the IT-infrastructure are, the better its scalability is.
The more complex the infrastructure is, the more different systems it includes and the more vulnerable it is. For example, banking systems process information backed by real money. And access to this data can lead to serious losses.
Therefore, the information security system in banks necessarily includes the management of access rights, encryption of communication channels, total monitoring and maintaining detailed logs.
- The speed of changes
Competition greatly affects the fact that companies are constantly improving the level of their service.
Changing of business processes should be supported by IT-infrastructure services: if a decision is made about changes, then it should be implemented as soon as possible.
- Transparency and manageability
The simpler and more transparent the infrastructure is, the easier the management will be. Transparency is achieved by collecting data on the company’s information system. This includes everything that allows you to predict the behavior of IT with any changes. The more information about the processes and the state of the IT infrastructure is taken into account, the more accurately we can predict its behavior and, consequently, the more effectively we can manage it. If each event is not only recorded, but also described, this will provide a more complete forecast in case of a problem in the future.
- Adequate cost of ownership
Large company spend money mostly on support of the infrastructure, which implies a constant adjustment to the current needs of the business. For modern large companies, changing is not cheap. Therefore, the requirement of a reasonable cost of ownership of the IT-infrastructure becomes particularly important.
- Modular structure
It allows you to add new functionality and get rid of obsolete components with minimal cost. It is important that the IT infrastructure built on a modular basis and based on the mainstream technologies: this will make it possible to make changes to it in a short time and at minimal cost. If earlier IT only supported business processes, now they are becoming an integral part of business, the very essence of innovation.
