IT Architecture is a series of policies, principles, procedures, requirements, standards, guidelines, models, road-maps and rules used by an enterprise to direct the process of acquiring, building, modifying and interfacing IT resources throughout the enterprise in-line with the business goals.

TechExpert can facilitate the implementation of an architecture that aligns with your business goals incorporating heritage equipment, procedures and staff expertise with new industry standards, best practices and techniques maximizing future potentials and reducing risk.
IT Architecture consists of a number of fields as described below requiring an extensive background both in depth and width, and in my case 8 years of university, continuing education with MIT Online Courses, and over 40 years of industry experience:
- Solution Architecture: is a practice of defining and describing an architecture of a system delivered in context of a specific solution and as such it may encompass description of an entire system or only its specific parts.
- Enterprise Architecture: is “a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes.
- Information Systems or Technology Architecture: is the process of development of methodical information technology specifications, models and guidelines, using a variety of Information Technology notations, for example UML, within a coherent Information Technology architecture framework, following formal and informal Information Technology solution, enterprise, and infrastructure architecture processes.
- Data or Information Architecture: is composed of models, policies, rules or standards that govern which data is collected, and how it is stored, arranged, integrated, and put to use in data systems and in organizations.
- Business Architecture: is a discipline that “represents holistic, multidimensional business views of: capabilities, end‐to‐end value delivery, information, and organizational structure; and the relationships among these business views and strategies, products, policies, initiatives, and stakeholders
- Application Architecture: describes the behavior of applications used in a business, focused on how they interact with each other and with users. It is focused on the data consumed and produced by applications rather than their internal structure. In application portfolio management, applications are mapped to business functions and processes as well as costs, functional quality and technical quality in order to assess the value provided.
- Security Architecture: is the practice of applying a comprehensive and rigorous method for describing a current and/or future structure and behavior for an organization’s security processes, information security systems, personnel, and organizational sub-units so that they align with the organization’s core goals and strategic direction.
