Brief Explanation of Enterprise Architecture:
Enterprise Architecture is a concept that provides a blueprint that specifies organizational structure and operations. The objective of EA is to identify how an organization can achieve present and future goals efficiently. This approach includes the process of assessing, planning, designing, and ultimately carrying out analysis of an organization.
Enterprise Architecture assists organizations experience digital transformation, as it concentrates on putting together all existing available technologies and procedures in an effort to create a seamless environment. In light of advancements in business innovation during the 1980s, the utilization of EA systems expanded as a requirement for an approach to adjust to fast development in innovation was fundamental to business technique. This method was later stretched to a business entirely, not just for Information Technology (IT). In this manner as a whole, all organizations would be aligned with digital transformations.
Enterprise architecture principles are variable so for each organization it won’t look the same. For instance, software developers and other technical professionals interpret strategies for enterprise architecture in terms of technology, application, and management components as they track them under their control. However, as company architects are responsible for determining the layout of the corporation.
Enterprise Architecture Process:
Enterprise architecture is defined into four phases. They are:
- Design & Arrange
- Procure and Execute
- Freight and support system
- Control, Analyze, and Evaluate.
Microsoft’s Michael Platt, a chief in the vital task division, gives a perspective on big business engineering as having four perspectives: the market viewpoint, the application point of view, the data point of view, and the innovation viewpoint. The corporate viewpoint describes the procedures and practices by which the company functions on a daily basis. Developers will utilize endeavor engineering when alluding to the parts of the equipment and programming in a framework. This could include a web server, database, NoSQL database cache, API endpoints, and content delivery network for a website.
For explanations of technical enterprise architecture, EA may revolve around the nature of software architecture, types of implementation of systems architecture, and other steps such as testing.
EA Models and Paradigm:
Usually, enterprise architectures are implemented as frameworks. There are several different structures and when it comes to any one entity, some would be a better match than others. For example, a system based on continuity and relationships between different parts of a larger entity would be more effective compared to smaller entities with several moving pieces. A framework such as the Unified Architecture Framework (UAF) can operate in this case.
Advantages of Enterprise Architecture:
- Enhance managerial decisions.
- Improved adaptability to changing market conditions or demands.
- Removing obsolete and redundant processes.
- Optimizations of organizational resources utilization.
- Minimization of turnover of the employees.
- Enable improvements in organization for the restructuring and reorganization.
- Allows architecture easier to test against long-term goals.
- Can offer those outside IT views of the IT architectures.
- Can help unify processes within IT.
- Can help the finance teams simplify and
- Facilitates coordination with the management of programs.
Enterprise Architecture Management in ITIL: As per ITIL the IT Architecture Management approach intends to establish a blueprint for future improvement of the technological environment, taking into consideration the service approach and emerged technologies.
ITIL Enterprise Architecture:
ITIL Architecture management only defined as a method only for ITIL in design, and ITIL v3 official documentation does not specify details about this process. But this approach is used throughout the lifecycle phase to preserve the standard technology architecture design of an organization. The application perspective describes the relations between the organization’s processes and standards. The data point of view depicts and orders the crude information, (for example, text documents, data sets, pictures, introductions, and spreadsheets) required by the association for powerful activity.
ITIL V2 Framework in Enterprise Architecture:
IT Knowledge Library-based Management of IT Resources (ITIL-ITSM) is an IT method and operation Management System with a collection of best practices related to each collection of IT Processes.
ITIL offers a comprehensive range of best practices, drawn globally from the public and private sectors. It consists of seven collections of books related to the market viewpoint, Service implementation planning, Admin, service delivery, support systems, admin of ICT infrastructures, applications, management, and handling security.
Need for Enterprise Architecture:
- Coalition: Architecture aligns strategy with market demand and IT supply, ensuring the transition is in line with strategy and objectives.
- Thorough Understanding: Enterprise Architecture offers a thorough understanding of the current state of the organization, data, and system.
- Quality: EA sets and enhances the quality of solutions by simplifying their engineering and monitoring through the process.
The latest methods and methodologies have come into existence to assist Enterprise Architecture practitioners to benefit business architecture to help in investment and implementing decisions, which involves business benefitting models, business paradigms, etc.
ITIL architecture management seeks to define a model for the future implementation of the technological environment, considering service methodologies and available innovations. It offers guidance on architectural issues in the context of technology-related-activities. The main objective of IT architecture is to develop a solid foundation through which new services are upgraded.
