Читать книгу IT Architecture from A to Z: Theoretical basis. First Edition - Vadim Aldzhanov - Страница 22

Based on the requirements and constraints defined above, you can summarize the basic approach in building the company’s IT architecture:

• Service oriented approach to building IT architecture;

• Minimizing risks by using tested and well-proven technologies and solutions;

• Reducing costs by maximizing and optimizing the use of current IT assets and solutions;

• Reducing the complexity and heterogeneity of the existing infrastructure;

• Maximum possible rational approach to the consolidation of IT assets (hardware, software), keeping the level of user support and / or specialized systems at the periphery;

• Multiple use of IT assets (IT personnel) on projects within the company;

• Standardizing IT assets (hardware, software and solutions) to reduce the cost of ownership, complexity of maintenance and increase information security;

• Implementation of single IT policies and procedures to reduce the cost of ownership, complexity of maintenance and increase information security in the company;

• Automation of routine IT processes to reduce the cost of ownership, maintenance complexity and increase information security;

• Creating a single information security policy in the organization;

• Creating a project team with a high level of competence.

Compatibility

Wherever possible, consider the availability of existing systems and maximize their benefits. This will reduce the cost of replacement, or the implementation and maintenance of new systems.

Following the main principles

When implementing new or intermediate solutions, or launching a business (or expanding it), it is recommended to be guided by the main requirements stipulated by this document. The cost of the solution and maintenance of IT infrastructure directly depends on the choice of a solution.
