Development and design of critical IT infrastructure architecture

When developing and designing IT architecture, we rely on TOGAF (The Open Group Architecture Framework) information systems (IS) architecture structure methodology.
In this way, we ensure that the IT infrastructure architecture we develop meets the highest quality and functionality standards and serves customers efficiently, applying world-renowned practices. The design is certified according to the ISO 9K standard
TOGAF is based on four interrelated areas of specialization:

1. Organizational Architecture: built on business strategy, management, organization, and core business processes of an organization.
2. Data Architecture: defines the logical and physical data resources of an organization and the associated data management resources.
3. Application Architecture: defines individual detailed technical plans for individual deployment of systems, system interactions, and includes systems interaction with the organization's business processes and functions.
4. Technology Architecture: defines the physical, software, and network infrastructure required to support the deployment of critical applications.

The Architecture Development Method (ADM) is used to create and modify the architecture, which involves a cycle of four interactions:

1. Architectural context: preliminary stage; architectural vision;
2. Provision of architecture: business architecture; Information systems architecture; Technology architecture;
3. Transition planning: opportunities and solutions; migration planning;
4. Architecture Management: Implementation Management; architectural change management.
