IT-infrastructure   — it is a multicomponent integrated system that is a complex of information technologies (software and hardware) and ensures the activities of the organization. Computer hardware, software, network services, services, e-mail, monitoring systems, information security policies, control systems, backup and data storage systems, office equipment, telephony, etc. — these are all components.

Building an IT-infrastructure can include modern solutions in the field of:

  • effective communication (including e-mail, video and voice communication, organizing remote access to shared resources, linking remote departments, managing individual communication components);
  • system hardware and software systems for data centers (virtualization of workplaces and servers, element management, cloud computing);
  • setting access rights to data of this or that user, depending on the security policy in force at the enterprise;
  • organization of access to information regardless of the physical location of company employees;
  • workplace organization (setting up and managing hardware, software and software, managing users' computers);
  • ensuring effective interaction between company divisions, management of internal works and services of IT contractors (including the implementation and automation of ITSM);
  • maintenance of information security (analysis of probable risks, creation of protective mechanisms, effective information security management).
  • ensuring continued operation and utilization of hardware and software resources;
  • lower infrastructure maintenance costs;

IT-infrastructure planning

In order to start planning the future IT-infrastructure you need:
  • analyze the organization's business processes;
  • audit of IT infrastructure (if you plan to upgrade your IT infrastructure or migrate to a new one);
  • analyze the solutions, products, technologies, consumables available on the market and estimate the cost of their ownership (purchase, operation, maintenance costs);
  • calculate budgets and match opportunities to needs;

IT-infrastructure implementation

According to the approved terms of reference, the contractor starts to implement the project. Depending on the size of the project:
  • preparation of premises (SCS);
  • purchasing hardware and software;
  • installation and initial setup of equipment;
  • building a local area network;
  • install and configure software;
  • configuring services, connecting services;
  • creating users, grouping, setting permissions;
  • install and configure information security tools;
  • setting up the integration of information systems, services, services;
  • testing and performance testing according to the program and test methods;
  • writing documentation, service regulations, instructions.

After all the work, the infrastructure is put into pilot operation to test the work in production conditions, during which minor modifications are made and the project is handed over to the customer for operation or transferred to technical support for maintenance .

Operation and modernization of IT-infrastructure

During operation, the technical specialists of the customer or the contractor monitor the state of the IT-infrastructure, carry out preventive maintenance work with equipment and software, perform routine operations, collect and analyze feedback from users organizations and managers for use. For more information about the operation of the IT-infrastructure and its maintenance, see IT-outsourcing .
If, during the operation of the IT-infrastructure, new business processes appear in the organization, the existing ones change, the organization changes, we develop & mdash; there may be a need to modernize the IT-infrastructure.
Modernization can mean virtually any change to an IT-infrastructure to improve accessibility, safety and efficiency:
  • capacity building in connection with the development of the organization (purchase of computers, servers, licenses, disks, memory, etc.);
  • introduction of new systems, services, services into the existing infrastructure due to changes in business needs (teamwork tools, CRM, ERP, document management system, two-factor authentication, etc.);
  • introduction of information protection means due to changes in legislation or the emergence of new business areas (the need to ensure the safety of personal data, bank secrets, state secrets, etc.).
