As it stands today, how a business manages and manages its own IT infrastructure, data and applications has a direct and measurable impact on its success. In the era of digital transformation, IT services not only influence, but determine the operational activities of all departments of any organization.
Finally the moment came when it became clear that the old extensive approaches to IT development were no longer applicable. Solving emerging problems by simply increasing technical capacity – buying a new server, disk array or software – is not really a solution, but only postpones it. It is necessary to analyze the current situation, put things in order in activities and plan actions.
In order for the IT infrastructure to be able to solve business problems for many years, scaling and modernizing to meet the needs of the business, it is extremely important, at the stage of construction, to correctly plan the architecture of all IT systems and design their further interaction.
This has become especially important today, when IT directors have to choose among a variety of development paths. From physical infrastructure to many variations of hybrid infrastructures. A very important part of IT is IT infrastructure design services.
Accelerating technology update cycles today forces us to try to predict the future, and even at the design stage, provide for the best options for infrastructure development.
A properly designed IT infrastructure ultimately reduces specific IT costs, while a wrong one increases them. Easily scalable and modernizable IT infrastructure is able to adapt to changing business processes in the future with minimal costs.
A logical, structured, well-documented and expertly built IT infrastructure is a guarantee of a stable, uninterrupted workflow.
The general design formula is: “As it is – As it should – What to do.” And, following it, the stages of IT infrastructure design will be as follows…
- Audit. The current model of the IT infrastructure is being built, a complete inventory of its constituent components is carried out. An analysis is carried out for technological and structural redundancy, or scarcity. The level of compliance with current business processes and the potential for possible future scaling and restructuring are assessed.
- Formulation of the problem. In accordance with the wishes of the customer, the specifics of the enterprise and the required level of automation, the final goals are formulated.
- Concept. Several models are developed, analyzed, the optimal one is selected, corresponding to the allocated budget.
- Terms of Reference (TOR). A document is created containing the goals and objectives of the project. The functionality of the ready-made solution, its integration with other systems operating at the enterprise is described. The TOR also contains clear requirements for fault tolerance and safety level. The terms of reference indicate the stages of the project implementation, the resources required for this. After approval, the TOR becomes the main document for the implementation of the project.
- Working solution. A list of components of the future infrastructure is documented with an indication of the functionality that determines the processing purpose.
- Equipment. In accordance with the functional purpose and within the allocated budget, a list of equipment is created for the project: servers, communication and network equipment, workstations, security tools and systems.
- Testing. The operability of the selected model of IT infrastructure is checked on a data array and equipment purchased for the project.
- Functional processing topology. Detailed maps (diagrams) of the location and interaction of infrastructure components are created, policies for the use of software and local networks are developed.
